Our Time Is Running Out Fast
If you think this is an exaggerated or alarmist statement, you should keep reading.
I have tried over the years to paint a very sobering picture of our collective reality, this is what the facts on the ground dictated. Most (though not all) have completely rejected the dire message no matter how much factual data was presented to back it up. I and others have been sounding the alarm on the global meltdown, methane release, and the likelihood of a “runaway greenhouse effect”, for a very long time. Though such warnings have been generally discounted or ignored, denial will not stop what is now unfolding by the day. Even now the combined factors of Al Gore’s hypocrisy, the main stream media propaganda machine, and the “climate engineers”, have convinced a huge percentage of the population that the planet is cooling. Such conclusions will very soon be seen for what they are, patently false.
Industrialized civilization was never sustainable, and is now in its death throes. Collapse can not come soon enough if life on Earth is to have any chance of even shorter term survival.This is what all available statistics indicate, those who read on will be have much to consider.
I have waited to post completely unvarnished data as I have felt such information would either be completely rejected, or would shut down those that were committed enough to objectively examine it. It has been my hope that the degree of warning I had tried to pass on about climate engineering and the state of the biosphere would be enough to compel those who examined the information into making the fight to stop climate engineering their top priority, this has not happened in too many cases.
We live in a society based on near total denial and delusion. As the walls crumble around us all and resource wars rage around the world, few seem to sense the gravity of what is now upon us. We have precious little time left to make monumental changes, or all will most certainly be lost if it is not already.
The article below by Guy McPherson is long, but it is of immense importance.
Guy is professor emeritus of natural resources and the environment at the University of Arizona, where he taught and conducted research for twenty award-winning years. Guy has shown incredible courage for speaking out loudly and clearly with impeccable research and references. So much of the scientific community has been criminally silent on the true threat posed by Earth’s crumbling life support systems. The same scientists are outright lying to hide the decimation from geoengineering and the totality of what we face in an apparent attempt to keep populations calm and under control till the last minute.
One thing to keep in mind while reading the extremely important text (and references) below, there is no mention of the ongoing climate engineering. Though I can not speak for Mr. McPherson as to why, in my communications with him I believe it is likely he can not speak directly on the subject of global geoengineering without severe repercussion. Again, this is my conclusion and has not been stated by Guy McPherson himself.
No matter how dark the horizon, we can not and must not give up. No one can know with certainty how things will unfold. No one can foresee what unknown factors there may be in our favor if we can achieve a complete change of direction for humanity beginning with exposing and halting climate engineering. Now is when we find out what we are really made of.
Climate-change summary and update
Updated frequently, and most recently 17 March 2014. ** Latest additions are flagged with two asterisks on each side. **
I’m often accused of cherry picking the information in this ever-growing essay. I plead guilty, and explain myself in this essay posted 30 January 2014.
American actress Lily Tomlin is credited with the expression, “No matter how cynical you become, it’s never enough to keep up.” With respect to climate science, my own efforts to stay abreast are blown away every week by new data, models, and assessments. It seems no matter how dire the situation becomes, it only gets worse when I check the latest reports.
The response of politicians, heads of non-governmental organizations, and corporate leaders remains the same. They’re mired in the dank Swamp of Nothingness. As Hallor Thorgeirsson, a senior director with the United Nations Framework Convention on Climate Change, said on 17 September 2013: “We are failing as an international community. We are not on track.” These are the people who know about, and presumably could do something about, our ongoing race to disaster (if only to sound the alarm). Tomlin’s line is never more germane than when thinking about their pursuit of a buck at the expense of life on Earth.
Worse than the aforementioned trolls are the media. Fully captured by corporations and the corporate states, the media continue to dance around the issue of climate change. Occasionally a forthright piece is published, but it generally points in the wrong direction, such as suggesting climate scientists and activists be killed (e.g., James Delingpole’s 7 April 2013 hate-filled article in the Telegraph). Leading mainstream outlets routinely lie to the public. According to a report published 11 January 2014, “the BBC has spent tens of thousands of pounds over six years trying to keep secret an extraordinary ‘eco’ conference which has shaped its coverage of global warming.” At the 2006 event, green activists and scientists — one of whom believes climate change is a bigger danger than global nuclear war — lectured 28 of the BBC’s most senior executives.
Mainstream scientists minimize the message at every turn. As we’ve known for years, scientists almost invariably underplay climate impacts. And in some cases, scientists are aggressively muzzled by their governments. I’m not implying conspiracy among scientists. Science selects for conservatism. Academia selects for extreme conservatism. These folks are loathe to risk drawing undue attention to themselves by pointing out there might be a threat to civilization. Never mind the near-term threat to our entire species (they couldn’t care less about other species). If the truth is dire, they can find another, not-so-dire version. The concept is supported by an article in the February 2013 issue of Global Environmental Change pointing out that climate-change scientists routinely underestimate impacts “by erring on the side of least drama.”
Ever late to the party, the Intergovernmental Panel on Climate Change (IPCC) admits global warming is irreversible without geoengineering in a report released 27 September 2013. As pointed out in the 5 December 2013 issue of Earth System Dynamics, known strategies for geoengineering are unlikely to succeed (“climate geo-engineering cannot simply be used to undo global warming“). “Attempts to reverse the impacts of global warming by injecting reflective particles into the stratosphere could make matters worse,” according to research published in the 8 January 2014 issue of Environmental Research Letters. In addition, as described in the December 2013 issue of Journal of Geophysical Research: Atmospheres, geoengineering may succeed in cooling the Earth, it would also disrupt precipitation patterns around the world. Furthermore, “risk of abrupt and dangerous warming is inherent to the large-scale implementation of SRM” (solar radiation management), as pointed out in the 17 February 2014 issue of Environmental Research Letters. Finally, “schemes to minimize the havoc caused by global warming by purposefully manipulating Earth’s climate are likely to either be relatively useless or actually make things worse,” judging from research published in the 25 February 2014 issue of Nature Communications. As it turns out, the public isn’t impressed, either: Research published in the 12 January 2014 issue of Nature Climate Change “reveals that the overall public evaluation of climate engineering is negative.”
Gradual change is not guaranteed, as pointed out by the U.S. National Academy of Sciences in December 2013: “The history of climate on the planet — as read in archives such as tree rings, ocean sediments, and ice cores — is punctuated with large changes that occurred rapidly, over the course of decades to as little as a few years.” The December 2013 report echoes one from Wood Hole Oceanographic Institution more than a decade earlier.
If you’re too busy to read the evidence presented below, here’s the bottom line: On a planet 4 C hotter than baseline, all we can prepare for is human extinction (from Oliver Tickell’s 2008 synthesis in the Guardian). Tickell is taking a conservative approach, considering humans have not been present at 3.5 C above baseline (i.e., the beginning of the Industrial Revolution, commonly accepted as 1750). According to the World Bank’s 2012 report, “Turn down the heat: why a 4°C warmer world must be avoided” and an informed assessment of “BP Energy Outlook 2030” put together by Barry Saxifrage for the Vancouver Observer, our path leads directly to the 4 C mark. The 19th Conference of the Parties of the UN Framework Convention on Climate Change (COP 19), held in November 2013 in Warsaw, Poland, was warned by professor of climatology Mark Maslin: “We are already planning for a 4°C world because that is where we are heading. I do not know of any scientists who do not believe that.” Adding to planetary misery is a paper in the 16 December 2013 issue of the Proceedings of the National Academy of Sciences concluding that 4 C terminates the ability of Earth’s vegetation to sequester atmospheric carbon dioxide.
I’m not sure what it means to plan for 4 C (aka extinction). I’m not impressed that civilized scientists claim to be planning for it, either.
According to Colin Goldblatt, author of a paper published online in the 28 July 2013 issue of Nature Geoscience, “The runaway greenhouse may be much easier to initiate than previously thought.” Furthermore, as pointed out in the 1 August 2013 issue of Science, in the near term Earth’s climate will change orders of magnitude faster than at any time during the last 65 million years. Tack on, without the large and growing number of self-reinforcing feedback loops we’ve triggered recently, the 5 C rise in global-average temperature 55 million years ago during a span of 13 years, and it looks like trouble ahead for the wise ape. This conclusion ignores the long-lasting, incredibly powerful greenhouse gas discovered 9 December 2013 by University of Toronto researchers: perfluorotributylamine (PFTBA) is 7,100 times more powerful than carbon dioxide as a greenhouse gas in the atmosphere, and it persists hundreds of years in the atmosphere. It also ignores the irreversible nature of climate change: Earth’s atmosphere will harbor, at minimum, the current level of atmospheric carbon dioxide concentration for at least the next 1,000 years, as indicated in the 28 January 2009 issue of the Proceedings of the National Academy of Sciences.
Finally, far too late, the New Yorker posits a relevant question on 5 November 2013: Is It Too Late to Prepare for Climate Change? Joining the too-little, too-late gang, the Geological Society of London points out on 10 December 2013 that Earth’s climate could be twice as sensitive to atmospheric carbon as previously believed. ** New Scientist piles on in March 2014, pointing out that planetary warming is far more sensitive to atmospheric carbon dioxide concentration than indicated by past reports. ** As usual and expected, carbon dioxide emissions set a record again in 2013, the fifth-warming year on record and the second-warmest year without an El Nino. ** Another El Niño is on the way, as pointed out by Robert Scribbler on 6 March 2014: “Should the predicted El Nino emerge and be as strong as average model values indicate, global surface temperatures could rise by between .05 and .15 degrees Celsius …. This would be a substantial jump for a single year, resulting in yet one more large shift toward an ever more extreme climate.” Indeed, he upper end of the projected range takes us to 1 C warmer than baseline. **
All of the above information fails to include the excellent work by Tim Garrett, which points out that only complete collapse avoids runaway greenhouse. Garrett reached the conclusion in a paper submitted in 2007 (personal communication) and published online by Climatic Change in November 2009 (outcry from civilized scientists delayed formal publication until February 2011). The paper remains largely ignored by the scientific community, having been cited fewer than ten times since its publication.
According to Yvo de Boer, who was executive secretary of the United Nations Framework Convention on Climate Change in 2009, when attempts to reach a deal at a summit in Copenhagen crumbled with a rift between industrialized and developing nations, “the only way that a 2015 agreement can achieve a 2-degree goal is to shut down the whole global economy.” Politicians finally have caught up with Tim Garrett’s excellent paper in Climatic Change.
Writing for the Arctic Methane Emergency Group, John Davies concludes: “The world is probably at the start of a runaway Greenhouse Event which will end most human life on Earth before 2040.” He considers only atmospheric carbon dioxide concentration, not the many self-reinforcing feedback loops described below. Tacking on only one feedback loop, and writing on 28 November 2013 — methane release from the Arctic Ocean — Sam Carana expects global temperature anomalies up to 20 C 2050 (an anomaly is an aberration, or deviation from long-term average). Small wonder atmospheric methane can cause such global catastrophe considering its dramatic rise during the last few years, as elucidated by Carana on 5 December 2013 in the figure below.
On the topic of tipping points, we crossed the Rubicon in 2007 at about 0.76 C warming. At this point, according to David Spratt’s excellent September 2013 report, “Is Climate Already Dangerous?”, not only had Arctic sea-ice passed its tipping point, but the Greenland Ice Sheet was not far behind, as the Arctic moves to sea-ice-free conditions in summer (the U.S. Navy predicts an ice-free Arctic by summer 2016, a year later than expected by the United Kingdom Parliament, which points out that the six lowest September ice extents have occurred in the last six years). Glaciologist Jason Box, an expert on Greenland ice, agrees. Box was quoted in a 5 December 2012 article in the Guardian: “In 2012 Greenland crossed a threshold where for the first time we saw complete surface melting at the highest elevations in what we used to call the dry snow zone. … As Greenland crosses the threshold and starts really melting in the upper elevations it really won’t recover from that unless the climate cools significantly for an extended period of time which doesn’t seem very likely.” ** Indeed, as stated that same year in the September issue of Global Policy, “because of increasing temperatures due to GHG emissions a suite of amplifying feedback mechanisms, such as massive methane leaks from the sub-sea Arctic Ocean, have engaged and are probably unstoppable.” By December 2013, the disappearance of Greenland’s ice had accelerated to five times the pace of a few years previously, and IPCC was acknowledging they’d been far too conservative with past estimates. Continued conservatism is buttressed by research reported in the 16 March 2014 issue of Nature Climate Change indicating melting of Greenland ice accounts for about one-sixth of recent sea-level rise. **
If you think we’ll adapt, think again. The rate of evolution trails the rate of climate change by a factor of 10,000, according to a paper in the August 2013 issue of Ecology Letters. And it’s not as if extinction events haven’t happened on this planet, as explained in the BBC program, The Day the Earth Nearly Died.
The rate of climate change clearly has gone beyond linear, as indicated by the presence of the myriad self-reinforcing feedback loops described below, and now threatens our species with extinction in the near term. As Australian biologist Frank Fenner said in June 2010: “We’re going to become extinct,” the eminent scientist says. “Whatever we do now is too late.” Anthropologist Louise Leakey ponders our near-term demise in her 5 July 2013 assessment at Huffington Post and her father Richard joins the fray in this video from December 2013 (see particularly 1:02:18 – 1:02:56). Canadian wildlife biologist Neil Dawe joins the party of near-term extinction in an interview 29 August 2013 and musician-turned-activist Sir Bob Geldof joins the club in a Daily Star article from 6 October 2013. In the face of near-term human extinction, most Americans view the threat as distant and irrelevant, as illustrated by a 22 April 2013 article in the Washington Post based on poll results that echo the long-held sentiment that elected officials should be focused on the industrial economy, not far-away minor nuisances such as climate change.
Supporters of carbon farming — the nonsensical notion that industrial civilization can be used to overcome a predicament created by industrial civilization — claim all we need to do is fill the desert with nonnative plants to the tune of an area three-quarters the size of the United States. And, they say, we’ll be able to lower atmospheric carbon dioxide by a whopping 17.5 ppm in only two decades. Well, how exciting. At that blistering pace, atmospheric carbon dioxide will be all the way back down to the reasonably safe level of 280 ppm in only 140 years, more than a century after humans are extinct from climate change.
According to the plan presented in the 23 August 2013 issue of Scientific American, the nonnative plants, irrigated with increasingly rare fresh water pumped by increasingly rare fossil-fuel energy, will sequester carbon sufficient to overcome contemporary emissions. Never mind the emissions resulting from pumping the water, or the desirability of converting thriving deserts into monocultures, or the notion of maintaining industrial civilization at the expense of non-civilized humans and non-human species. Instead, ponder one simple thought: When the nonnative plants die, they will emit back into the atmosphere essentially all the carbon they sequestered. A tiny bit of the carbon will be stored in the soil. The rest goes into the atmosphere as a result of decomposition.
This essay brings attention to recent projections and positive feedbacks. I presented much of this information at the Bluegrass Bioneers conference (Alex Smith at Radio Ecoshock evaluates my presentation here). More recently, I presented an updated version on the campus of the University of Massachusetts. All information and sources are readily confirmed with an online search, and links to information about feedbacks can be found here.
Intergovernmental Panel on Climate Change (late 2007): >1.8 C by 2100
Hadley Centre for Meteorological Research (late 2008): ~2 C by 2100
Later in 2008, Hadley Center’s head of climate change predictions Dr. Vicky Pope calls for a worst-case outcome of more than 5 C by 2100. Joe Romm, writing for Grist, claims, “right now even Hadley [Centre] understands it [> 5 C] is better described as the ‘business-as-usual’ case.”
United Nations Environment Programme (mid 2009): 3.5 C by 2100
Hadley Centre for Meteorological Research (October 2009): 4 C by 2060
Global Carbon Project, Copenhagen Diagnosis (November 2009): 6 C, 7 C by 2100
United Nations Environment Programme (December 2010): up to 5 C by 2050
These assessments fail to account for significant self-reinforcing feedback loops (i.e., positive feedbacks, the term that implies the opposite of its meaning). The IPCC’s vaunted Fifth Assessment continues the trend as it, too, ignores important feedbacks. On a positive note, major assessments fail to account for economic collapse. However, due to the four-decade lag between emissions and temperature rise as well as the feedback loops described below, I strongly suspect it’s too late for economic collapse to extend the run of our species. Indeed, as pointed out by Bruce Melton at Truthout in a 26 December 2013 piece featuring climate scientist Wallace Broeker: “today we are operating on atmospheric concentrations of greenhouse gases from the 1970s. In the last 29 years we have emitted as many greenhouse gases as we emitted in the previous 236 years. Because of the great cooling effect of the oceans, we have not yet begun to see the warming that this recent doubling of greenhouse gases will bring.”
The 40-year has been evident since at least 1938, when Guy Callendar pointed out influence of rising carbon dioxide on temperature in a paper in the Quarterly Journal of the Royal Meteorological Society. The hand-drawn figure from the paper shown below clearly illustrates a rise in global-average temperature beginning about 1915, roughly 40 years after the consumption of fossil fuels increased substantially.
Taking a broad view
Astrophysicists have long believed Earth was near the center of the habitable zone for humans. Recent research published in the 10 March 2013 issue of Astrophysical Journal indicates Earth is on the inner edge of the habitable zone, and lies within 1% of inhabitability (1.5 million km, or 5 times the distance from Earth to Earth’s moon). A minor change in Earth’s atmosphere removes human habitat. Unfortunately, we’ve invoked major changes.
The northern hemisphere is particularly susceptible to accelerated warming, as explained in the 8 April 2013 issue of Journal of Climate. Two days later, a paper in Nature confirmed that summers in the northern hemisphere are hotter than they’ve been for 600 years. As pointed out by Sherwood and Huber in the 25 May 2012 issue of the Proceedings of the National Academy of Sciences and then by James Hansen in his 15 April 2013 paper, humans cannot survive a wet-bulb temperature of 35 C (95 F).
As described by the United Nations Advisory Group on Greenhouse Gases in 1990, “Beyond 1 degree C may elicit rapid, unpredictable and non-linear responses that could lead to extensive ecosystem damage” (link mirrored here). James Hansen and crew finally caught up to the dire nature of 1 C warming 23 years after the U.N. warning, 28 self-reinforcing feedback loops too late. Planetary instruments indicate Earth has warmed about 1 C since the beginning of the industrial revolution. However, plant flowering dates in the vicinity of Concord, Massachusetts — where the instrumental record indicates warming of about 2.4 C — indicate accelerated flowering date that closely correlate to 2.4 C warming since the 1840s.
Whether you believe the plants or the instruments is irrelevant at the point. We’ve clearly triggered the types of positive feedbacks the United Nations warned about in 1990. Yet my colleagues and acquaintances think we can and will work our way out of this horrific mess with permaculture (which is not to denigrate permaculture, the principles of which are implemented at the mud hut). Reforestation doesn’t come close to overcoming combustion of fossil fuels, as pointed out in the 30 May 2013 issue of Nature Climate Change. Furthermore, forested ecosystems do not sequester additional carbon dioxide as it increases in the atmosphere, as disappointingly explained in the 6 August 2013 issue of New Phytologist. Adding egregious insult to spurting wound, the latest public-education initiative in the United States — the Next Generation Science Standards — buries the relationship between combustion of fossil fuels and planetary warming. The misadventures of the corporate government continue, even as collapse of ecosystems is fully under way. As pointed out in the April 2013 issue of PLoS ONE — too little, too late for many ecosystems — “catastrophic collapses can occur without prior warning.”
Hopium-addicted greenwashing solutionistas take refuge in the nuclear solution. It’s astonishing what one can conclude when grid-tied electricity is a viewed as a natural right. James Hansen’s endorsement notwithstanding, nuclear power plants cause, rather than prevent, additional warming of Earth.
Let’s ignore the models for a moment and consider only the results of a single briefing to the United Nations Conference of the Parties in Copenhagen (COP15). Regulars in this space will recall COP15 as the climate-change meetings thrown under the bus by the Obama administration. The summary for that long-forgotten briefing contains this statement: “THE LONG-TERM SEA LEVEL THAT CORRESPONDS TO CURRENT CO2 CONCENTRATION IS ABOUT 23 METERS ABOVE TODAY’S LEVELS, AND THE TEMPERATURES WILL BE 6 DEGREES C OR MORE HIGHER. THESE ESTIMATES ARE BASED ON REAL LONG TERM CLIMATE RECORDS, NOT ON MODELS.”
In other words, near-term extinction of humans was already guaranteed, to the knowledge of Obama and his administration (i.e., the Central Intelligence Agency, which runs the United States and controls presidential power). Even before the dire feedbacks were reported by the scientific community, the administration abandoned climate change as a significant issue because it knew we were done as early as 2009. Rather than shoulder the unenviable task of truth-teller, Obama did as his imperial higher-ups demanded: He lied about collapse, and he lied about climate change. And he still does.
Ah, those were the good ol’ days, back when atmospheric carbon dioxide concentrations were below 400 parts per million (ppm). We’ll blow through the 400 ppm mark soon, probably for the first time in 3.2 to 5 million years. And, as reported in the journal Global and Planetary Change in April 2013, every molecule of atmospheric carbon dioxide since 1980 comes from human emissions. Not to be outdone, methane levels reached an average mean of 1800 parts per billion (ppb) on the morning of 16 June 2013. ** Tacking on a few of the additional greenhouse gases contributing to climate change and taking a conservative approach jacks up the carbon dioxide equivalent to 480 ppm. ** Seeps are appearing in numerous locations off the eastern coast of the United States, leading to rapid destabilization of methane hydrates (according to the 25 October 2013 issue of Nature). On land, anthropogenic emissions of methane in the United States have been severely underestimated by the Environmental Protection (sic) Agency, according to a paper in the 25 November 2013 issue of Proceedings of the National Academy of Sciences. This figure is 1100 ppb higher than pre-industrial peak levels. Methane release tracks closely with temperature rise throughout Earth history — specifically, Arctic methane release and rapid global temperature rise are interlinked — including a temperature rise up to about 1 C per year over a decade, according to data from ice cores. The tight linkage between Arctic warming and global warming was verified in an article in the 2 February 2014 issue Nature Geoscience, which found that the Arctic’s cap of cold, layered air plays a more important role in boosting polar warming than does its shrinking ice and snow cover. A layer of shallow, stagnant air acts like a lid, concentrating heat near the surface.
1. Methane hydrates are bubbling out the Arctic Ocean (Science, March 2010). As described in a subsequent paper in the June 2010 issue of Geophysical Research Letters, a minor increase in temperature would cause the release of upwards of 16,000 metric tons of methane each year. According to NASA’s CARVE project, these plumes were up to 150 kilometers across as of mid-July 2013. Global-average temperature is expected to rise by more than 4 C by 2030 and 10 C by 2040 based solely on methane release from the Arctic Ocean, according to Sam Carana’s research (see especially Image 24). Whereas Malcolm Light’s 9 February 2012 forecast of extinction of all life on Earth by the middle of this century appears premature because his conclusion of exponential methane release during summer 2011 was based on data subsequently revised and smoothed by U.S. government agencies, subsequent information — most notably from NASA’s CARVE project — indicates the grave potential for catastrophic release of methane. (I doubt industrial civilization manages to kill all life on Earth, although that clearly is the goal.) Catastrophically rapid release of methane in the Arctic is further supported by Nafeez Ahmed’s thorough analysis in the 5 August 2013 issue of the Guardian as well as Natalia Shakhova’s 29 July 2013 interview with Nick Breeze (note the look of abject despair at the eight-minute mark). In early November 2013, methane levels well in excess of 2,600 ppb were recorded at multiple altitudes in the Arctic. Later that same month, Shakhova and colleagues published a paper in Nature Geoscience suggesting “significant quantities of methane are escaping the East Siberian Shelf” and indicating that a 50-billion-tonne “burst” of methane could warm Earth by 1.3 C. Such a burst of methane is “highly possible at any time.” By 15 December 2013, methane bubbling up from the seafloor of the Arctic Ocean had sufficient force to prevent sea ice from forming in the area. Nearly two years after his initial, oft-disparaged analysis, Malcolm Light concluded on 22 December 2013, “we have passed the methane hydrate tipping point and are now accelerating into extinction as the methane hydrate ‘Clathrate Gun’ has begun firing volleys of methane into the Arctic atmosphere.” According to Light’s analysis in late 2013, the temperature of Earth’s atmosphere will resemble that of Venus before 2100. Two weeks later, in an essay stressing near-term human extinction, Light concluded: “The Gulf Stream transport rate started the methane hydrate (clathrate) gun firing in the Arctic in 2007 when its energy/year exceeded 10 million times the amount of energy/year necessary to dissociate subsea Arctic methane hydrates.”
Discussion about methane release from the Arctic Ocean has been quite heated (pun intended). Paul Beckwith was criticized by the conservative website, Skeptical Science. His response from 9 August 2013 is here.
Robert Scribbler provides a terrifying summary 24 February 2014, and concludes, “two particularly large and troubling ocean to atmosphere methane outbursts were observed” in the Arctic Ocean. Such an event hasn’t occurred during the last 45 million years. Scribbler’s bottom line: “that time of dangerous and explosive reawakening, increasingly, seems to be now.”

2. Warm Atlantic water is defrosting the Arctic as it shoots through the Fram Strait (Science, January 2011). Subsequent melting of Arctic ice is reducing albedo, hence enhancing absorption of solar energy. “Averaged globally, this albedo change is equivalent to 25% of the direct forcing from CO2 during the past 30 years,” according to research published in the 17 February 2014 issue of the Proceedings of the National Academy of Sciences. Destabilization of the deep circulation in the Atlantic Ocean may be “spasmodic and abrupt rather than a more gradual increase” as earlier expected, according to a paper published in the 21 February 2014 issues of Science. ** Models continue to underestimate relative to observations, as reported in the 10 March 2014 issue of Geophysical Research Letters. **
3. Siberian methane vents have increased in size from less than a meter across in the summer of 2010 to about a kilometer across in 2011 (Tellus, February 2011). According to a paper in the 12 April 2013 issue of Science, a major methane release is almost inevitable, which makes me wonder where the authors have been hiding. Almost inevitable, they report, regarding an ongoing event.
4. Peat in the world’s boreal forests is decomposing at an astonishing rate (Nature Communications, November 2011)
5. Invasion of tall shrubs warms the soil, hence destabilizes the permafrost (Environmental Research Letters, March 2012)
7. Methane is being released from the Antarctic, too (Nature, August 2012). According to a paper in the 24 July 2013 issue of Scientific Reports, melt rate in the Antarctic has caught up to the Arctic and the West Antarctic Ice Sheet is losing over 150 cubic kilometres of ice each year according to CryoSat observations published 11 December 2013, and Antarctica’s crumbling Larsen B Ice Shelf is poised to finish its collapse, according to Ted Scambos, a glaciologist at the National Snow and Ice Data Center at the annual meeting of the American Geophysical Union. Further confirmation of large methane releases is revealed by noctilucent clouds over the southern hemisphere from 21 November 2013 to 6 December 2013.
8. Russian forest and bog fires are growing (NASA, August 2012), a phenomenon consequently apparent throughout the northern hemisphere (Nature Communications, July 2013). The New York Times reports hotter, drier conditions leading to huge fires in western North America as the “new normal” in their 1 July 2013 issue. A paper in the 22 July 2013 issue of the Proceedings of the National Academy of Sciences indicates boreal forests are burning at a rate exceeding that of the last 10,000 years.
9. Cracking of glaciers accelerates in the presence of increased carbon dioxide (Journal of Physics D: Applied Physics, October 2012)
11. Exposure to sunlight increases bacterial conversion of exposed soil carbon, thus accelerating thawing of the permafrost (Proceedings of the National Academy of Sciences, February 2013)
12. The microbes have joined the party, too, according to a paper in the 23 February 2013 issue of New Scientist
13. Summer ice melt in Antarctica is at its highest level in a thousand years: Summer ice in the Antarctic is melting 10 times quicker than it was 600 years ago, with the most rapid melt occurring in the last 50 years (Nature Geoscience, April 2013). ** According to a paper in the 4 March 2014 issue of Geophysical Research Letters — which assumes relatively little change in regional temperature during the coming decades — “modeled summer sea-ice concentrations decreased by 56% by 2050 and 78% by 2100″ (Robert Scribbler’s in-depth analysis is here). ** Although scientists have long expressed concern about the instability of the West Antarctic Ice Sheet (WAIS), a research paper published in the 28 August 2013 of Nature indicates the East Antarctic Ice Sheet (EAIS) has undergone rapid changes in the past five decades. The latter is the world’s largest ice sheet and was previously thought to be at little risk from climate change. But it has undergone rapid changes in the past five decades, signaling a potential threat to global sea levels. The EAIS holds enough water to raise sea levels more than 50 meters.
14. Increased temperature and aridity in the southwestern interior of North America facilitates movement of dust from low-elevation deserts to high-elevation snowpack, thus accelerating snowmelt, as reported in the 17 May 2013 issue of Hydrology and Earth System Sciences.
15. Floods in Canada are sending pulses of silty water out through the Mackenzie Delta and into the Beaufort Sea, thus painting brown a wide section of the Arctic Ocean near the Mackenzie Delta brown (NASA, June 2013). ** Pictures of this phenomenon are shown on this NASA website. **
16. Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, according to a study accepted for publication in the Journal of Geophysical Research: Earth Surface (July 2013). It appears a Heinrich Event has been triggered in Greenland. Consider the description of such an event as provided by Robert Scribbler on 8 August 2013:
In a Heinrich Event, the melt forces eventually reach a tipping point. The warmer water has greatly softened the ice sheet. Floods of water flow out beneath the ice. Ice ponds grow into great lakes that may spill out both over top of the ice and underneath it. Large ice damns (sic) may or may not start to form. All through this time ice motion and melt is accelerating. Finally, a major tipping point is reached and in a single large event or ongoing series of such events, a massive surge of water and ice flush outward as the ice sheet enters an entirely chaotic state. Tsunamis of melt water rush out bearing their vast floatillas (sic) of ice burgs (sic), greatly contributing to sea level rise. And that’s when the weather really starts to get nasty. In the case of Greenland, the firing line for such events is the entire North Atlantic and, ultimately the Northern Hemisphere.
17. Breakdown of the thermohaline conveyor belt is happening in the Antarctic as well as the Arctic, thus leading to melting of Antarctic permafrost (Scientific Reports, July 2013). ** In the past 60 years, the ocean surface offshore Antarctica became less salty as a result of melting glaciers and more precipitation, as reported in the 2 March 2014 issue of Nature Climate Change. **
18. Loss of Arctic sea ice is reducing the temperature gradient between the poles and the equator, thus causing the jet stream to slow and meander (see particularly the work of Jennifer Francis). One result is the creation of weather blocks such as the recent very high temperatures in Alaska. As a result, boreal peat dries and catches fire like a coal seam. The resulting soot enters the atmosphere to fall again, coating the ice surface elsewhere, thus reducing albedo and hastening the melting of ice. Each of these individual phenomena has been reported, albeit rarely, but to my knowledge the dots have not been connected beyond this space. The inability or unwillingness of the media to connect two dots is not surprising, and has been routinely reported (recently including here with respect to climate change and wildfires) (July 2013)
21. Drought-induced mortality of trees contributes to increased decomposition of carbon dioxide into the atmosphere and decreased sequestration of atmospheric carbon dioxide. Such mortality has been documented throughout the world since at least November 2000 in Nature, with recent summaries in the February 2013 issue of Nature for the tropics and in the August 2013 issue of Frontiers in Plant Science for temperate North America.
One extremely important example of this phenomenon is occurring in the Amazon, where drought in 2010 led to the release of more carbon than the United States that year (Science, February 2011). In addition, ongoing deforestation in the region is driving declines in precipitation at a rate much faster than long thought, as reported in the 19 July 2013 issue of Geophysical Research Letters. ** An overview of the phenomenon, focused on the Amazon, was provided by Climate News Network on 5 March 2014. **
22. Ocean acidification leads to release of less dimethyl sulphide (DMS) by plankton. DMS shields Earth from radiation. (Nature Climate Change, online 25 August 2013). Plankton form the base of the marine food web, and are on the verge of disappearing completely, according to a paper in the 17 October 2013 issue of Global Change Biology.
23. Sea-level rise causes slope collapse, tsunamis, and release of methane, as reported in the September 2013 issue of Geology. In eastern Siberia, the speed of coastal erosion has nearly doubled during the last four decades as the permafrost melts.
25. Earthquakes trigger methane release, and consequent warming of the planet triggers earthquakes, as reported by Sam Carana at the Arctic Methane Emergency Group (October 2013)
27. Mixing of the jet stream is a catalyst, too. High methane releases follow fracturing of the jet stream, accounting for past global-average temperature rises up to 16 C in a decade or two (Paul Beckwith via video on 19 December 2013).
** 29. “Thawing permafrost promotes microbial degradation of cryo-sequestered and new carbon leading to the biogenic production of methane” (Nature Communications, February 2014) **
30. Arctic drilling was fast-tracked by the Obama administration during the summer of 2012
31. Supertankers are taking advantage of the slushy Arctic, demonstrating that every catastrophe represents a business opportunity, as pointed out by Professor of journalism Michael I. Niman and picked up by Truthout (ArtVoice, September 2013)
As nearly as I can distinguish, only the latter two feedback processes are reversible at a temporal scale relevant to our species. Once you pull the tab on the can of beer, there’s no keeping the carbon dioxide from bubbling up and out. These feedbacks are not additive, they are multiplicative: They not only reinforce within a feedback, the feedbacks also reinforce among themselves. Now that we’ve entered the era of expensive oil, I can’t imagine we’ll voluntarily terminate the process of drilling for oil and gas in the Arctic (or anywhere else). Nor will we willingly forgo a few dollars by failing to take advantage of the long-sought Northwest Passage.
Robin Westenra provides an assessment of these positive feedbacks at Seemorerocks on 14 July 2013. It’s worth a look.
See how far we’ve come
Never mind that American naturalist George Perkins Marsh predicted anthropogenic climate change as a result of burning fossil fuels in 1847. Never mind the warning issued by filmmaker Frank Capra in 1958 or the one issued by José Antonio Viera-Gallo, Assistant Secretary of Justice in the Chilean government of Salvador Allende, in 1973: “the impact of industrially packaged quanta of energy on the social environment tends to be degrading, exhausting, and enslaving, and these effects come into play even before those which threaten the pollution of the physical environment and the extinction of the (human) race.” Never mind that climate risks have been underestimated for the last 20 Years, or that the IPCC’s efforts have failed miserably (David Wasdell’s scathing indictment of the vaunted Fifth Assessment is archived here. After all, climate scientist Kevin Anderson tells us what I’ve known for years: politicians and the scientists writing official reports on climate change are lying, and we have less time than most people can imagine. Never mind David Wasdell pointed out in 2008 that we must have a period of negative radiative forcing merely to end up with a stable, non-catastrophic climate system. Never mind that even the Atlantic is displaying “five charts about climate change that should have you very, very worried.” Never mind that atmospheric carbon dioxide is affecting satellites. Never mind that even the occasional economic analyst is telling climate scientists to be persuasive, be brave, and be arrested. Never mind that Peruvian ice requiring 1,600 years to accumulate has melted in the last 25 years, according to a paper in the 4 April 2013 issue of Science. And never mind that summer warming in the interior of large continents in the northern hemisphere has outstripped model predictions in racing to 6-7 C since the last Glacial Maximum, according to a paper that tallies temperature rise in China’s interior in the 15 May 2013 issue of the Proceedings of the National Academy of Sciences. ** And finally, never mind that the IPCC’s projections have been revealed as too conservative time after time, including low-balling the impact of emissions, as pointed out in the 9 March 2014 issue of Nature Climate Change. **
Never mind all that: Future temperatures likely will be at the higher end of the projected range because the forecasts are all too conservative and also because climate negotiations won’t avert catastrophe.
Through late March 2013, global oceans have risen approximately ten millimeters per year during the last two years. This rate of rise is over three times the rate of sea level rise during the time of satellite-based observations from 1993 to the present. Ocean temperatures are rising, and have been impacting global fisheries for four decades, according to the 16 May 2013 issue of Nature.
Actually, catastrophe is already here, although it’s not widely distributed in the United States. Well, not yet, even though the continental U.S. experienced its highest temperature ever in 2012, shattering the 1998 record by a full degree Fahrenheit. But the east coast of North America experienced its hottest water temperatures all the way to the bottom of the ocean. The epic dust bowl of 2012 grew and grew and grew all summer long. As pointed out in the March 2004 issue of Geophysical Research Letters, disappearing sea ice is expectedly contributing to the drying of the western United States (more definitive research on the topic appeared in the December 2005 issue of Earth Interactions). Equally expectedly, the drought arrived 40 years early.
Even James Hansen and Makiko Sato are asking whether the loss of ice on Greenland has gone exponential (while ridiculously calling for a carbon tax to “fix” the “problem”), and the tentative answer is not promising, based on very recent data, including a nearly five-fold increase in melting of Greenland’s ice since the 1990s and a stunning melting of 98 percent of Greenland’s ice surface between 8 and 15 July 2012. The mainstream media are finally taking notice, with the 18 July 2013 issue of Washington Post reporting the ninth highest April snow cover in the northern hemisphere giving way to the third lowest snow cover on record the following month (relevant records date to 1967, and the article is headlined, “Snow and Arctic sea ice extent plummet suddenly as globe bakes”).
On a particularly dire note for humanity,
climate change causes early death of 400,000 people each year causes early death of five million people each year. Adding to our misery are interactions between various aspects of environmental decay. For example, warming in the Arctic is causing the release of toxic chemicals long trapped in the region’s snow, ice, ocean and soil, according to research published in the 24 July 2011 issue of Nature Climate Change.
Greenhouse-gas emissions keep rising, and keep setting records. According to 10 June 2013 report by the International Energy Agency, the horrific trend continued in 2012, when carbon dioxide emissions set a record for the fifth consecutive year. The trend puts disaster in the cross-hairs, with the ever-conservative International Energy Agency claiming we’re headed for a temperature in excess of 5 C.
Completely contrary to the popular contrarian myth, global warming has accelerated, with more overall global warming in the 15 years up to March 2013 than the prior 15 years. This warming has resulted in about 90% of overall global warming going into heating the oceans, and the oceans have been warming dramatically, according to a paper published in the March 2013 issue of Geophysical Research Letters. Even Slate magazine figured it out by 5 November 2013, and The Guardian‘s headline from 13 November 2013 announces, “Global warming since 1997 more than twice as fast as previously estimated, new study shows.” About 30% of the ocean warming over the past decade has occurred in the deeper oceans below 700 meters, which is unprecedented over at least the past half century. According to a paper in the 1 November 2013 issue of Science, the rate of warming of the Pacific Ocean during the last 60 years is 15 times faster than at any time during the last 10,000 years. By the end of 2013, the fourth-hottest year on record, the deep oceans were warming particularly rapidly and NASA and NOAA reported no pause in the long-term warming trend. “In 2013 ocean warming rapidly escalated, rising to a rate in excess of 12 Hiroshima bombs per second — over three times the recent trend.” When the heat going into the ocean begins to influence land-surface temperatures, “rapid warming is expected,” according to a paper published 9 February 2014 in Nature Climate Change. According to James Wight, writing for Skeptical Science on 12 March 2014, “Earth is gaining heat faster than ever.”
Coincident with profound ocean warming, the death spiral of Arctic sea ice is well under way, as shown in the video below.
In the category of myth busting comes recent research published in the August 2013 issue of Proceedings of the National Academy of Sciences. Contrary to the notion that changing solar radiation is responsible for rising global temperature, the amount of solar radiation passing through Earth’s atmosphere and reaching the ground globally peaked in the 1930s, substantially decreased from the 1940s to the 1970s, and changed little after that. Indeed, the current solar activity cycle is the weakest in a century. In addition, according to a paper in the 22 December 2013 issue of Nature GeoScience, climate change has not been strongly influenced by variations in heat from the sun.
Global loss of sea ice matches the trend in the Arctic. It’s down, down, and down some more, with the five lowest values on record all happening in the last seven years (through 2012). As reported in a June 2013 issue of Science, the Antarctic’s ice shelves are melting from below. When interviewed for the associated article in the 13 June 2013 issue of National Geographic, scientists expressed surprise at the rate of change. Color me shocked. Three months later, the 13 September 2013 issue of Science contains another surprise for mainstream scientists: The Pine Island Glacier is melting from below as a result of warming seawater. And four months after that dire assessment, the massive glacier was melting irreversibly, according to a paper in the 12 January 2014 issue of Nature Climate Change (Robert Scribbler provides an overview of the latter phenomenon).
Then see where we’re going
The climate situation is much worse than I’ve led you to believe, and is accelerating far more rapidly than accounted for by models. Even the U.S. Centers for Disease Control and Prevention acknowledges, in a press release dated 6 June 2013, potentially lethal heat waves on the near horizon. Piling on a month later, the World Meteorological Organization pointed out that Earth experienced unprecedented recorded climate extremes during the decade 2001-2010, contributing to more than a 2,000 percent increase in heat-related deaths.
Although climate change’s heat — not cold — is the real killer, according to research published in the December 2013 issue of the Journal of Economic Literature, swings in temperature may be even more lethal than high temperatures. Specifically, research published in the 29 January 2014 issue of the Proceedings of the Royal Society of London indicates insects are particularly vulnerable to temperature swings.
Ice sheet loss continues to increase at both poles, and warming of the West Antarctic Ice Sheet is twice the earlier scientific estimate. Arctic ice at all-time low, half that of 1980, and the Arctic lost enough sea ice to cover Canada and Alaska in 2012 alone. In short, summer ice in the Arctic is nearly gone. Furthermore, the Arctic could well be free of ice by summer 2015, an event that last occurred some three million years ago, before the genus Homo walked the planet. Among the consequences of declining Arctic ice is extremes in cold weather in northern continents (thus illustrating why “climate change” is a better term than “global warming”). In a turn surprising only to mainstream climate scientists, Greenland ice is melting rapidly.
Even the conservative International Energy Agency (IEA) has thrown in the towel, concluding that “renewable” energy is not keeping up with the old, dirty standard sources. As a result, the IEA report dated 17 April 2013 indicates the development of low-carbon energy is progressing too slowly to limit global warming.
The Arctic isn’t Vegas — what happens in the Arctic doesn’t stay in the Arctic — it’s the planet’s air conditioner. In fact, as pointed out 10 June 2013 by research scientist Charles Miller of NASA’s Jet Propulsion Laboratory: “Climate change is already happening in the Arctic, faster than its ecosystems can adapt. Looking at the Arctic is like looking at the canary in the coal mine for the entire Earth system.” In addition, “average summer temperatures in the Canadian Arctic are now at the highest they’ve been for approaching 50,000 years” (and perhaps up to 120,000 years) according to a paper published online 23 October 2013 in Geophysical Research Letters. On the topic of rapidity of change, a paper in the August 2013 issue of Ecology Letters points out that rates of projected climate change dramatically exceed past rates of climatic niche evolution among vertebrate species. In other words, vertebrates cannot evolve or adapt rapidly enough to keep up with ongoing and projected changes in climate.
How critical is Arctic ice? Whereas nearly 80 calories are required to melt a gram of ice at 0 C, adding 80 calories to the same gram of water at 0 C increases its temperature to 80 C. Anthropogenic greenhouse-gas emissions add more than 2.5 trillion calories to Earth’s surface every hour (ca. 3 watts per square meter, continuously).
Ocean acidification associated with increased atmospheric carbon dioxide is proceeding at an unprecedented rate — the fastest in 300 million years — leading to great simplification of ecosystems, and capable of triggering mass extinction by itself. Already, half the Great Barrier Reef has died during the last three decades. As with many attributes, the Arctic Ocean leads the way in acidification. ** Similarly to the long lag in temperature relative to increase greenhouse gas emissions, changes in ocean acidity lag far behind alterations in atmospheric carbon dioxide, as reported in the 21 February 2014 issue of Environmental Research Letters. **
An increasing number of scientists agree that warming of 4 to 6 C causes a dead planet. And, they go on to say, we’ll be there much sooner than most people realize. Earth-system scientist Clive Hamilton concludes in his April 2013 book Earthmasters that “without [atmospheric sulphates associated with industrial activity] … Earth would be an extra 1.1 C warmer.” In other words, collapse takes us directly to 2 C within a matter of weeks. According to a paper in the 24 November 2013 issue of Nature Climate Change, warming of the planet will continue long after emissions cease. Several other academic scientists have concluded, in the refereed journal literature no less, that the 2 C mark is essentially impossible (for example, see the review paper by Mark New and colleagues published in the 29 November 2010 issue of the Philosophical Transactions of the Royal Society A). The German Institute for International and Security Affairs concluded 2 June 2013 that a 2 C rise in global-average temperature is no longer feasible (and Spiegel agrees, finally, in their 7 June 2013 issue), while the ultra-conservative International Energy Agency concludes that, “coal will nearly overtake oil as the dominant energy source by 2017 … without a major shift away from coal, average global temperatures could rise by 6 degrees Celsius by 2050, leading to devastating climate change.” At the 11:20 mark of this video, climate scientist Paul Beckwith indicates Earth could warm by 6 C within a decade. If you think his view is extreme, consider (1) the 5 C rise in global-average temperature 55 million years ago during a span of 13 years (reported in the 1 October 2013 issue of Proceedings of the National Academy of Sciences), and also (2) the reconstruction of regional and global temperature for the past 11,300 years published in Science in March 2013. One result is shown in the figure below.
It’s not merely scientists who know where we’re going. The Pentagon is bracing for public dissent over climate and energy shocks, as reported by Nafeez Ahmed in the 14 June 2013 issue of the Guardian. According to Ahmed’s article: “Top secret US National Security Agency (NSA) documents disclosed by the Guardian have shocked the world with revelations of a comprehensive US-based surveillance system with direct access to Facebook, Apple, Google, Microsoft and other tech giants. New Zealand court records suggest that data harvested by the NSA’s Prism system has been fed into the Five Eyes intelligence alliance whose members also include the UK, Canada, Australia and New Zealand.” In short, the “Pentagon knows that environmental, economic and other crises could provoke widespread public anger toward government and corporations” and is planning accordingly. Such “activity is linked to the last decade of US defence planning, which has been increasingly concerned by the risk of civil unrest at home triggered by catastrophic events linked to climate change, energy shocks or economic crisis — or all three.” The global police state has arrived, and it’s accompanied by a subtle changes in Earth’s rotation that result from the melting of glaciers and ice sheets (i.e., climate change is causing Earth’s poles to shift).
