Climate Change

The collapse of large parts of the ice sheet in West Antarctica appears to have begun and is almost certainly unstoppable, with global warming accelerating the pace of the disintegration, two groups of scientists reported Monday.

The finding, which had been feared by some scientists for decades, means that a rise in global sea level of at least 10 feet may now be inevitable. The rise may continue to be relatively slow for at least the next century or so, the scientists said, but sometime after that it will probably speed up so sharply as to become a crisis.

“This is really happening,” said Thomas P. Wagner, who runs NASA’s programs on polar ice and helped oversee some of the research. “There’s nothing to stop it now. But you are still limited by the physics of how fast the ice can flow.”

Whatever the mix of causes, they appear to have triggered a retreat of the ice sheet that can no longer be stopped, even if the factors drawing in the warmer water were to reverse suddenly, the scientists said. At this point, a decrease in the melt rate back to earlier levels would be “too little, too late to stabilize the ice sheet,” said Ian Joughin, a glaciologist at the University of Washington and lead author of the new paper in Science. “There’s no stabilization mechanism.”

The basic problem is that much of the West Antarctic ice sheet sits below sea level in a kind of bowl-shaped depression the earth. As Dr. Mercer outlined in 1978, once the part of the ice sheet sitting on the rim of the bowl melts and the ice retreats into deeper water, it becomes unstable and highly vulnerable to further melting.

Richard B. Alley, a climate scientist at Pennsylvania State University who was not involved in the new research but has studied the polar ice sheets for decades, said he found the new papers compelling. Though he has long feared the possibility of ice-sheet collapse, when he learned of the new findings, “it shook me a little bit,” Dr. Alley said.

He added that while a large rise of the sea may now be inevitable from West Antarctica, continued release of greenhouse gases will almost certainly make the situation worse. The heat-trapping gases could destabilize other parts of Antarctica as well as the Greenland ice sheet, causing enough sea-level rise that many of the world’s coastal cities would eventually have to be abandoned.

Resting atop a deep marine basin, the West Antarctic Ice Sheet has long been considered prone to instability. Using a numerical model, we investigate the sensitivity of Thwaites Glacier to ocean melt and whether unstable retreat is already underway.

Our model reproduces observed losses when forced with ocean melt comparable to estimates. Simulated losses are moderate (<0.25 mm per year sea level) over the 21st Century, but generally increase thereafter.

Except possibly for the lowest-melt scenario, the simulations indicate early-stage collapse has begun. Less certain is the timescale, with onset of rapid (> 1 mm per year of sea-level rise) collapse for the different simulations within the range of two to nine centuries.

Widespread, rapid grounding line retreat of Pine Island, Thwaites, Smith and Kohler glaciers, West Antarctica from 1992 to 2011. - Rignot - Geophysical Research Letters - Wiley Online Library

We measure the grounding line retreat of glaciers draining the Amundsen Sea Embayment of West Antarctica using Earth Remote Sensing (ERS-1/2) satellite radar interferometry from 1992 to 2011. Pine Island Glacier retreated 31?km at its center, with most retreat in 2005–2009 when the glacier un-grounded from its ice plain.

Thwaites Glacier retreated 14?km along its fast-flow core and 1 to 9?km along the sides. Haynes Glacier retreated 10?km along its flanks. Smith/Kohler glaciers retreated the most, 35?km along its ice plain, and its ice shelf pinning points are vanishing.

These rapid retreats proceed along regions of retrograde bed elevation mapped at a high spatial resolution using a mass conservation technique (MC) that removes residual ambiguities from prior mappings.

Upstream of the 2011 grounding line positions, we find no major bed obstacle that would prevent the glaciers from further retreat and draw down the entire basin.
 
[Mercer 1978] West Antarctic Ice Sheet And CO2 Greenhouse Effect: A Threat Of Disaster

If the global consumption of fossil fuels continues to grow at its present rate, atmospheric CO2 content will double in about 50 years. Climatic models suggest that the resultant greenhouse-warming effect will be greatly magnified in high latitudes. The computed temperature rise at lat 80° S could start rapid deglaciation of West Antarctica, leading to a 5 m rise in sea level.

The accelerating rate of climate change poses a severe risk to national security and acts as a catalyst for global political conflict, a report published Tuesday by a leading government-funded military research organization concluded.

The CNA Corporation Military Advisory Board found that climate change-induced drought in the Middle East and Africa is leading to conflicts over food and water and escalating longstanding regional and ethnic tensions into violent clashes. The report also found that rising sea levels are putting people and food supplies in vulnerable coastal regions like eastern India, Bangladesh and the Mekong Delta in Vietnam at risk and could lead to a new wave of refugees.

In addition, the report predicted that an increase in catastrophic weather events around the world will create more demand for American troops, even as flooding and extreme weather events at home could damage naval ports and military bases.

In an interview, Secretary of State John Kerry signaled that the report’s findings would influence American foreign policy.

“Tribes are killing each other over water today,” Mr. Kerry said. “Think of what happens if you have massive dislocation, or the drying up of the waters of the Nile, of the major rivers in China and India. The intelligence community takes it seriously, and it’s translated into action.”

Mr. Kerry, who plans to deliver a major speech this summer on the links between climate change and national security, said his remarks would also be aimed at building political support for President Obama’s climate change agenda, including a new regulation to cut pollution from coal-fired power plants that the administration will introduce in June.

“We’re going to try to lay out to people legitimate options for action that are not bank-breaking or negative,” Mr. Kerry said.

Pentagon officials said the report would affect military policy. “The department certainly agrees that climate change is having an impact on national security, whether by increasing global instability, by opening the Arctic or by increasing sea level and storm surge near our coastal installations,” John Conger, the Pentagon’s deputy under secretary of defense for installations and environment, said in a statement. “We are actively integrating climate considerations across the full spectrum of our activities to ensure a ready and resilient force.”

The report on Tuesday follows a recent string of scientific studies that warn that the effects of climate change are already occurring and that flooding, droughts, extreme storms, food and water shortages and damage to infrastructure will occur in the near future.

In March, the Pentagon’s Quadrennial Defense Review, the agency’s main public document describing the current doctrine of the United States military, drew a direct link between the effects of global warming — like rising sea levels and extreme weather patterns — and terrorism.

“These effects are threat multipliers that will aggravate stressors abroad, such as poverty, environmental degradation, political instability and social tensions — conditions that can enable terrorist activity and other forms of violence,” the review said.

Tuesday’s report is an update of a report by the center’s Military Advisory Board in 2007, the first major study to draw the link between climate change and national security. The report’s authors said the biggest change in the seven years between the two studies was the increase in scientific certainty about global warming, and of the link between global warming and security disruptions.

The 2007 report also described climate change as a “threat multiplier” or a problem that could enhance or contribute to already existing causes of global disruption. The 2014 report updates that language, calling climate change a “catalyst for conflict” — a phrase intentionally chosen, the report’s authors said, to signal that climate change is an active, driving force in starting conflict.

“In the past, the thinking was that climate change multiplied the significance of a situation,” said Gen. Charles F. Wald, who contributed to both reports and is retired from the Air Force. “Now we’re saying it’s going to be a direct cause of instability.”

The most recent scientific reports on climate change warn that increasing drought in Africa is now turning arable land to desert. The national security report’s authors conclude that the slow but steady expansion of the Sahara through Mali, which is killing crops and leaving farmers starving, may have been a contributing force in the jihadist uprising in that African country in 2012. Since then, Al Qaeda in the Islamic Maghreb has seized control of northern Mali and remains in conflict with the Malian government.

The report warns that rising sea levels in the United States imperil many of the Navy’s coastal installations. Last week, the White House released a National Climate Assessment report citing Norfolk, Va., as one of the cities most vulnerable to damage by rising sea levels. Norfolk is home to the world’s largest naval base as well as a nuclear submarine construction yard — all of which are vulnerable to destruction by rising sea levels, found in Tuesday’s report.

“Norfolk is so big, it’s so important to the Navy, it’s important to Virginia for jobs, and it would go,” General Wald said.

A scientific report released this week found that global warming has contributed to the melting of a large section of a West Antarctica ice sheet, which could lead to a rise in sea level of 10 feet or more.

Senator James M. Inhofe of Oklahoma, the ranking Republican on the Senate Armed Services Committee and a vocal skeptic of the established science that greenhouse gas emissions contribute to global warming, scoffed at the idea that climate change is linked to national security threats.

“There is no one in more pursuit of publicity than a retired military officer,” he said of the report’s authors. “I look back wistfully at the days of the Cold War. Now you have people who are mentally imbalanced, with the ability to deploy a nuclear weapon. For anyone to say that any type of global warming is anywhere close to the threat that we have with crazy people running around with nuclear weapons, it shows how desperate they are to get the public to buy this.”

Rear Admiral David Titley, a co-author of the report and a meteorologist who is retired from the Navy, said political opposition would not extinguish what he called the indisputable data in the report.

“The ice doesn’t care about politics or who’s caucusing with whom, or Democrats or Republicans,” said Admiral Titley, who now directs the Center for Solutions to Weather and Climate Risk at Pennsylvania State University.
Correction: May 14, 2014

Because of an editing error, an earlier version of this article misstated the military rank of David Titley. He is Rear Admiral, not Admiral. Also because of an editing error, an earlier version stated incorrectly the name of a leading government-funded military research organization that released a report on the accelerating risks of climate change. It is the CNA Corporation Military Advisory Board, not the Center for Naval Analyses Military Advisory Board. (CNA is not an acronym.)

IPCC reports 'diluted' under 'political pressure' to protect fossil fuel interests
Saudi-led coalition sought to make policy summaries as vague as possible to minimise climate action

Increasing evidence is emerging that the policy summaries on climate impacts and mitigation by the UN Intergovernment Panel on Climate Change (IPCC) were significantly 'diluted' under political pressure from some of the world's biggest greenhouse gas emitters, including Saudi Arabia, China, Brazil and the United States.
 
An Obama Advisor Is Attacking Me for Testifying That Climate Change Hasn't Increased Extreme Weather

Does Climate Change Cause Extreme Weather? I Said No, and Was Attacked | New Republic


By Roger Pielke Jr.

Last Friday, the White House posted on its website a six-page criticism of me by the president’s science advisor, John Holdren, expanding on testimony he had given to Congress last week claiming that my views on climate change and extreme weather are outside of "mainstream scientific opinion.” Holdren was specifically responding to Senate testimony I gave last year where I argued that recent extreme weather events, including hurricanes, droughts, floods, and tornadoes, have not increased in recent decades due to human-caused climate change.

In this debate the facts are on my side. The claims I made in my congressional testimony are no different from the ones made by the Intergovernmental Panel on Climate Change ("Long-term trends in economic disaster losses adjusted for wealth and population increases have not been attributed to climate change, but a role for climate change has not been excluded") and broadly supported in the peer-reviewed scientific literature. Even Warren Buffett recently explained that more extreme events haven't affected his insurance investments, but that "I love apocalyptic predictions" because they increase insurance rates, earning him more money. When Holdren links specific weather events to human-caused climate change—such as the California drought or the cold winter—he is exaggerating the state of scientific understandings.

His subsequent attack on me has him serving not as science advisor to the president, but rather wielding his political position to delegitimize an academic whose views he finds inconvenient. We academics wouldn't stand for such behavior under George W. Bush and we shouldn't under Barack Obama either.

Our debate aside, Holdren’s exaggerations on climate science will make it harder, not easier, to establish a bipartisan consensus for action on climate change.

As background, I am an expert on the relationship between natural disasters and climate change. I have published extensively in the scientific, peer-reviewed literature over the past several decades. I believe the basic science of climate change is sound and has been for decades. Humans influence the climate today and will into the future, mainly through the emission of carbon dioxide from the burning of fossil fuels, and this influence poses unknown, but potentially large and irreversible risks in the future. The conclusions lay at the core of the work of the Intergovernmental Panel on Climate Change, which despite a few missteps along the way, has well-summarized these fundamental understandings.

Moreover, I have argued for nearly two decades that stronger policy action is needed by nations to both mitigate and adapt to climate change. I have called for a carbon tax linked to greater government spending on energy technology innovation. And I have supported what President Obama has done to combat climate change, including stronger regulations on efficiency, power plants, and his funding for energy innovation and investment overseas.

Why, then, am I being attacked by the White House science advisor as outside the scientific mainstream?

Because I have also argued against exaggerating the relationship between climate change and extreme weather. While politicians and environmental advocates routinely attribute natural disasters with human-caused climate change, the uncomfortable reality is that such attribution remains speculative. There is not yet a scientific basis for making such a connection. That is not an argument against taking action, but it is an argument for accurately representing the science.

Start with drought. According to the U.S. Climate Change Science Program, drought has, “for the most part, become shorter, less frequent, and cover a smaller portion of the U.S. over the last century. The main exception is the Southwest and parts of the interior of the West, where increased temperature has led to rising drought trends.” Globally, according to the IPCC in its special report on extreme events, “There is medium confidence that since the 1950s some regions of the world have experienced a trend to more intense and longer droughts, in particular in southern Europe and West Africa, but in some regions droughts have become less frequent, less intense, or shorter, for example, in central North America and northwestern Australia.”

A new review paper just out by a team of drought experts from around the world, and who hold a range of views on climate change and drought, explained many of the complexities, “How is drought changing as the climate changes? Several recent papers in the scientific literature have focused on this question but the answer remains blurred.”

And it’s not just drought. It is wrong to claim that disasters associated with hurricanes, tornadoes, or floods have increased on climate timescales either in the United States or globally. Hurricanes have not increased in the U.S. in frequency, intensity, or damage since at least 1900. The same holds for tropical cyclones globally since at least 1970 (at which point the data became available to allow for a global perspective).

Floods in the U.S. have not increased in frequency or intensity since at least 1950. Indeed, flood losses as a percentage of U.S. GDP have dropped by about 75 percent since 1940. At the global scale there is a similar lack of evidence for upwards trends in floods. Tornadoes have not increased in frequency, intensity or normalized damage in the U.S. since 1950, and there is some evidence to suggest that they have actually declined.

If this comes as a surprise to anyone it is because of the tendency by campaigners to cherry-pick details, obscure the larger context, and, ironically enough, attack as "deniers" anyone who disagrees.

A considerable body of research projects that various extremes may become more frequent and/or intense in the future as a direct consequence of human-caused climate changes. However, our research, and that of others, suggests that assuming that these projections are accurate, it will be many decades, perhaps longer, before the signal of human-caused climate change can be detected. Extremes are by definition rare events, and for that reason they are just not the best place to be looking for, or expecting to see, the consequences of climate change today.

Climate change is an important issue that will be managed for decades and centuries to come, making accurate representation of climate science by scientists and government officials crucial to maintaining public trust. Exaggerations by advocates of climate action, like those of science advisor Holdren, undermine that trust when they go beyond what the science is telling us. Efforts to quash mainstream, legitimate voices will further undermine that trust.
 
MIT Climate Scientist Responds on Disaster Costs And Climate Change
MIT Climate Scientist Responds on Disaster Costs And Climate Change | FiveThirtyEight

As someone who has spent some time looking at changes in the incidence of hurricanes around the planet, I have been asked to provide a response to Roger Pielke Jr.’s article “Disasters Cost More Than Ever — But Not Because of Climate Change,” published at FiveThirtyEight earlier this month.

Let me begin by saying that I am sympathetic to Pielke’s emphasis on the role of changing demographics in increasing damages from natural disasters. This is a serious problem that could be addressed by wiser policies. For example, in the United States, policies regulating insurance and providing federal flood insurance and disaster relief have the effect of subsidizing risk-taking, and the recent repeal of large sections of the 2012 Biggert-Waters Federal Flood Insurance Reform Act shows just how difficult it is to reform these risk-inducing policies.

Having said that, I’m not comfortable with Pielke’s assertion that climate change has played no role in the observed increase in damages from natural hazards; I don’t see how the data he cites support such a confident assertion.
 
Top scientific journal rejects Times front-page article claims
Top scientific journal rejects Times front-page article claims | Carbon Brief

A Times front page today claims a leading scientific journal has "deliberately suppressed" dissenting views on the severity of global warming.

But the scientific journal in question has dismissed the claims and taken the unusual step of publishing reviewer comments on the paper, which show reviewers had raised concerns about the quality of the research.


Statement from IOP Publishing on story in The Times
http://ioppublishing.org/newsDetails/statement-from-iop-publishing-on-story-in-the-times

Dr. Nicola Gulley, Editorial Director at IOP Publishing, says, “The draft journal paper by Lennart Bengtsson that Environmental Research Letters declined to publish, which was the subject of this morning’s front page story of The Times, contained errors, in our view did not provide a significant advancement in the field, and therefore could not be published in the journal.”

“The decision not to publish had absolutely nothing to do with any ‘activism’ on the part of the reviewers or the journal, as suggested in The Times’ article; the rejection was solely based on the content of the paper not meeting the journal’s high editorial standards, ” she continues.

“The referees selected to review this paper were of the highest calibre and are respected members of the international science community. The comments taken from the referee reports were taken out of context and therefore, in the interests of transparency, we have worked with the reviewers to make the full reports available.”

The full quote actually said “Summarising, the simplistic comparison of ranges from AR4, AR5, and Otto et al, combined with the statement they are inconsistent is less then helpful, actually it is harmful as it opens the door for oversimplified claims of "errors" and worse from the climate sceptics media side.”

Global warming: it's a point of no return in West Antarctica. What happens next?
Last week saw a 'holy shit' moment in climate change science. A landmark report revealed that the collapse of a large part of Antarctica is now unstoppable
Global warming: it's a point of no return in West Antarctica. What happens next? | Eric Rignot | Comment is free | The Observer

We announced that we had collected enough observations to conclude that the retreat of ice in the Amundsen sea sector of West Antarctica was unstoppable, with major consequences – it will mean that sea levels will rise one metre worldwide. What's more, its disappearance will likely trigger the collapse of the rest of the West Antarctic ice sheet, which comes with a sea level rise of between three and five metres. Such an event will displace millions of people worldwide.
 
Forget going green -- Earth doesn't care

Forget going green -- Earth doesn't care - Paul B. Farrell - MarketWatch
Cover story: "The Earth Doesn't Care If You Drive a Hybrid!" Or recycle. Or eat organic food. Or live in a green house powered by solar energy. Or squander commodities. The Earth just doesn't care how much you waste.

Was that a cover story in Mother Earth News? Or The Onion? No folks, it was the cover story in the elite American Scholar Journal by Nobel physicist Robert B. Laughlin of Stanford University. I bring it to your attention because in today's resurgence of Know-Nothing party politics few care what scholars say about anything.

But you better care. Laughlin pinpoints the key reason a global crisis is coming soon: What he says has everything to do with America's global warming policies, our deficits, hot commodities, investment strategies and how to live in an age of increasing warfare.

The Scholar's editor hammers home Laughlin's warning that "humans have already triggered the sixth great period of species extinction in Earth's history." The what? Yes, we are in an age of species extinction. And it's happening fast. The last extinction was 65 million years ago, at the end of the 250 million year Mesozoic era. But this one is very different. Ask yourself: Will the human species be the new dinosaurs, which vanished long before we arrived?

Your brain needs to shift into a new mindset to think like Laughlin, a physicist who thinks in geologic time, in hundreds of millions of years, about a planet that's been around over five billion years. Yes, geologic time is very long. But get this: The end may catch us by surprise. A sudden accelerating geologic quickie, like the asteroids that wiped out the dinosaurs. Or like the Earth's beginning, a sudden Big Bang.

But can anyone prepare? No. But not for lack of warnings. Why? Because our human brains can't see past our noses, let alone plan for obvious catastrophes.

Same when it comes to climate change and energy futures. Laughlin warns that our collective judgment is "fogged by misunderstandings about the Earth. Experts are little help in the constant struggle to separate myth from reality, because they have the same difficulty, and routinely demonstrate it by talking past each other."
We're committing suicide -- and our leaders are the executioners

And the experts will all miss it: "Respected scientists warn of imminent energy shortages as geologic fuel supplies run out. Wall Street executives dismiss their predictions as myths and call for more drilling. Environmentalists describe the destruction to the Earth from burning coal, oil and natural gas. Economists ignore them and describe the danger to the Earth of failing to burn coal, oil and natural gas. Geology researchers report fresh findings about what the Earth was like millions of years ago. Creationist researchers report fresh findings that the Earth didn't exist millions of years ago."

So the warnings just cancel out one another.

Laughlin's advice: "The only way not to get lost in this awful swamp is to review the basics and decide for yourself what you believe and what you don't." No, no, no. With the reemergence of Know-Nothing political discourse, myth and ideology beat reality and the facts.
Earth warns humans, you started the new species extinction

As anthropologist Jared Diamond put it in his classic "Collapse," our fate depends on leaders with "the courage to practice long-term thinking and to make bold, courageous, anticipatory decisions at a time when problems have become perceptible but before they reach crisis proportions"

Unfortunately, "this type of decision-making is the opposite of the short-term reactive decision-making that too often characterizes our elected politicians, focusing only on issues likely to blow up in a crisis within the next 90 days." Even if our leaders see a disaster coming, they'll ignore it, till it's too late.

Laughlin's no activist like Bill McKibben warning "that it might be too late. The science is settled, the damage has already begun." Laughlin's an academic scholar. You even sense he's talking to a dear old friend, Earth, in a special language both understand, a grumpy old friend who doesn't really give a damn whether you drive a hybrid, recycle, eat organic or live in a greenhouse fueled by solar power; a dear old friend who periodically (on its geologic timetable) gets extra grumpy and simply wipes out species that threaten its survival, including humans if we get too threatening. Listen to Laughlin:

"A considerable amount of evidence shows that humans are causing what biologists call the sixth mass extinction, an allusion to the five previous cases in the fossil record where huge numbers of species died out mysteriously in a flash of geologic time."

Like massive asteroids wiping out the dinosaurs "with the power of a million 100-megaton hydrogen warheads. The damage that human activity presently inflicts, many say, is comparable." Then he reminds us that "Earth didn't replace the dinosaurs after they died, notwithstanding the improved weather conditions and 20,000 ages of Moses to make repairs. It just moved on and became something different than it had been before."
The real problem? By 2050 we'll add too many cute new babies

So what's Earth now telling its old friend, Nobel physicist Laughlin? Earth is exposing the real problem that's forcing us into the sixth species extinction, the elimination of toxic species threatening Earth's survival: The "real problem is human population pressure generally -- overharvesting, habitat destruction, pesticide abuse, species invasion and so forth."

So what's the solution? "Slowing manmade extinctions in a meaningful way would require drastically reducing the world's human population. That is unlikely to happen." Get it? Population growth will continue inexorably from six billion to nine billion. Earth doesn't want 50% growth. So the sixth species extension is in progress.

Whether you're an activist or a climate-denier, you can rant and rave all you want -- for or against all the politically correct campaigns to cut carbon emissions, recycle plastic water bottles, eat locally grown organic food, tax breaks for solar energy, buying hybrids or greenophying urban skyscrapers. At best, all that jockeying around may delay the endgame -- the inevitable sixth species extinction -- by a few seconds on the geologic time-clock. But it won't stop the clock. Fifty percent growth guarantees extinctions.
Yes, you can delay ... but you cannot stop the inevitable

Yes, you can delay Earth's endgame scenario, says Laughlin. But nothing can change the Earth's trajectory on the new path of the sixth species extinction ... as long as China, India, Africa, Asia, the Americas and the rest of the world keep adding more babies, blowing up the population bubble from roughly 6 billion today to more than 9 billion by 2050. Remember, if all 6 billion Earth inhabitants used resources and generated as much waste as America today, we'd already need six Earths. With a 2050 population of 9 billion, it's "game over."

Laughlin's geologic-time equation says population is the key problem that renders all recycling-hybrid-organic-green-solar-energy solutions ineffective in stopping the inevitable species extinction. Population growth is the one key variable in the Earth's economic equation that actually accelerates all other problems.

Laughlin concludes like a conductor building to the grand climax of an orchestral masterpiece: "The great ice episodes were not the only cases of natural climate change, however. Six million years ago the Mediterranean Sea dried up. Ninety million years ago alligators and turtles cavorted in the Arctic. One hundred fifty million years ago the oceans flooded the middle of North America and preserved dinosaur bones. Three hundred million years ago, northern Europe burned to a desert and coal formed in Antarctica. The great ice episodes themselves were preceded by approximately 30 smaller ones between one and two million years ago."
This time is different. Why? The first 'species extinction' with people

"Nobody knows why these dramatic climate changes occurred in the ancient past. ... One thing we know for sure is that people weren't involved. There weren't enough people around during the ice episodes to matter, and there weren't any people around before the ice episodes." So can we do anything to stop the "sixth species extinction?" No.

Climate change "is a matter of geologic time, something that the Earth routinely does on its own without asking anyone's permission or explaining itself," warns Laughlin. Earth "doesn't include the potentially catastrophic effects on civilization in its planning. Far from being responsible for damaging the earth's climate, civilization might not be able to forestall any of these terrible changes once the earth has decided to make them ... climate ought not to concern us too much ... because it's beyond our power to control."

So if climate change is "beyond our control," why not accept it and enjoy life? Yes, forget about recycling, hybrids, solar cells, wind power, clean coal, desalination and living green. They're ineffective, can't stop the "sixth species extinction" ... as long as population continues growing out of control from six billion to nine billion.

In the end, however, no matter what Laughlin says, we are still masters of our fate, captains of our souls. Yes, we did light the fuse on the next "Big Bang," the population time bomb. Yes, we set in motion the "sixth species extinction." Yes, the "geologic time bomb" is ticking away. But we made the decision. Not Earth. Admit it. Take responsibility. Go enjoy life, live for today. And stop wasting time, money and energy on ineffective solutions to reverse the inevitable ending that we already set in motion.

The American Scholar: What the Earth Knows - Robert B. Laughlin

The sea has risen and fallen particularly vigorously over the past million years as a result of Ice Age glaciation. We know this because oxygen isotope ratios in the ocean sediments vary violently with depth. These ratios indirectly measure the amount of water locked up in glacial ice sheets at the time of sedimentation. The sediments record nine major glacial episodes, each of which lowered the sea level by more than 50 meters and then returned it abruptly to its present value. At least four of these episodes lowered the sea by more than 100 meters. This includes the most recent one, which lowered it 120 meters. The amount of lowering is corroborated by uplifted coral reefs, which show growth in places that would otherwise have been impossible because they require shallow water. It’s also consistent with estimates of the ice mass required to leave behind such industrial-strength mischief as Long Island, Nantucket, and the Great Lakes—about 50 million cubic kilometers in all, or five million billion tons.

The major glacial episodes are spectacular examples of the natural climate change that has occurred in geologic time. They took place at regular intervals of 100,000 years and always followed the same strange pattern of slow, steady cooling followed by abrupt warming back to conditions similar to today’s. We know this because chemical records in polar ice, the patterns of which match those of the sediments, contain a signal that strongly tracks the earth’s precessional wobble, the 24,000-year cyclic drift of the earth’s spin axis caused by the gravitational tugging of the moon and sun. The precession is a clock-like astronomical quantity, so its appearance in the ice data enables a precise dating of the ice. That, in turn, enables a precise dating of the sediments. The last glacial melting, cross-dated at 15,000 years ago by the radiocarbon age of wood debris left by the glaciers as they retreated, occurred rapidly. The sea rose more than one centimeter per year for 10,000 years, then stopped. The extra heat required for this melting was 10 times the present energy consumption of civilization. The total melt**water flow was the equivalent of two Amazons, or half the discharge of all the rivers in all the world.

The great ice episodes were not the only cases of natural climate change, however. Six million years ago the Mediterranean Sea dried up. Ninety million years ago alligators and turtles cavorted in the Arctic. One hundred fifty million years ago the oceans flooded the middle of North America and preserved dinosaur bones. Three hundred million years ago, northern Europe burned to a desert and coal formed in Antarctica. The great ice episodes themselves were preceded by approximately 30 smaller ones between one and two million years ago, and perhaps twice that many before that.

Nobody knows why these dramatic climate changes occurred in the ancient past. Ideas that commonly surface include perturbations to the earth’s orbit by other planets, disruptions of ocean currents, the rise and fall of greenhouse gases, heat reflection by snow, continental drift, comet impacts, Genesis floods, volcanoes, and slow changes in the irradiance of the sun. No scientifically solid support has been found for any of these suggestions. One thing we know for sure is that people weren’t involved. There weren’t enough people around during the ice episodes to matter, and there weren’t any people around before the ice episodes.

The geologic record as we know it thus suggests that climate is a profoundly grander thing than energy. Energy procurement is a matter of engineering and keeping the lights on under circumstances that are likely to get more difficult as time progresses. Climate change, by contrast, is a matter of geologic time, something that the earth routinely does on its own without asking anyone’s permission or explaining itself. The earth doesn’t include the potentially catastrophic effects on civilization in its planning. Far from being responsible for damaging the earth’s climate, civilization might not be able to forestall any of these terrible changes once the earth has decided to make them. Were the earth determined to freeze Canada again, for example, it’s difficult to imagine doing anything except selling your real estate in Canada. If it decides to melt Greenland, it might be best to unload your property in Bangladesh. The geologic record suggests that climate ought not to concern us too much when we’re gazing into the energy future, not because it’s unimportant, but because it’s beyond our power to control.

Dietary deficiencies of zinc and iron are a substantial global public health problem. An estimated two billion people suffer these deficiencies, causing a loss of 63?million life-years annually. Most of these people depend on C3 grains and legumes as their primary dietary source of zinc and iron. Here we report that C3 grains and legumes have lower concentrations of zinc and iron when grown under field conditions at the elevated atmospheric CO2 concentration predicted for the middle of this century. C3 crops other than legumes also have lower concentrations of protein, whereas C4 crops seem to be less affected. Differences between cultivars of a single crop suggest that breeding for decreased sensitivity to atmospheric CO2 concentration could partly address these new challenges to global health.
 
Joseph Bast and Roy Spencer: The Myth of the Climate Change '97%' - WSJ.com

Last week Secretary of State John Kerry warned graduating students at Boston College of the "crippling consequences" of climate change. "Ninety-seven percent of the world's scientists," he added, "tell us this is urgent."

Where did Mr. Kerry get the 97% figure? Perhaps from his boss, President Obama, who tweeted on May 16 that "Ninety-seven percent of scientists agree: #climate change is real, man-made and dangerous." Or maybe from NASA, which posted (in more measured language) on its website, "Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities."

Yet the assertion that 97% of scientists believe that climate change is a man-made, urgent problem is a fiction. The so-called consensus comes from a handful of surveys and abstract-counting exercises that have been contradicted by more reliable research.

One frequently cited source for the consensus is a 2004 opinion essay published in Science magazine by Naomi Oreskes, a science historian now at Harvard. She claimed to have examined abstracts of 928 articles published in scientific journals between 1993 and 2003, and found that 75% supported the view that human activities are responsible for most of the observed warming over the previous 50 years while none directly dissented.

Ms. Oreskes's definition of consensus covered "man-made" but left out "dangerous"—and scores of articles by prominent scientists such as Richard Lindzen, John Christy, Sherwood Idso and Patrick Michaels, who question the consensus, were excluded. The methodology is also flawed. A study published earlier this year in Nature noted that abstracts of academic papers often contain claims that aren't substantiated in the papers.

Another widely cited source for the consensus view is a 2009 article in "Eos, Transactions American Geophysical Union" by Maggie Kendall Zimmerman, a student at the University of Illinois, and her master's thesis adviser Peter Doran. It reported the results of a two-question online survey of selected scientists. Mr. Doran and Ms. Zimmerman claimed "97 percent of climate scientists agree" that global temperatures have risen and that humans are a significant contributing factor.

The survey's questions don't reveal much of interest. Most scientists who are skeptical of catastrophic global warming nevertheless would answer "yes" to both questions. The survey was silent on whether the human impact is large enough to constitute a problem. Nor did it include solar scientists, space scientists, cosmologists, physicists, meteorologists or astronomers, who are the scientists most likely to be aware of natural causes of climate change.

The "97 percent" figure in the Zimmerman/Doran survey represents the views of only 79 respondents who listed climate science as an area of expertise and said they published more than half of their recent peer-reviewed papers on climate change. Seventy-nine scientists—of the 3,146 who responded to the survey—does not a consensus make.

In 2010, William R. Love Anderegg, then a student at Stanford University, used Google Scholar to identify the views of the most prolific writers on climate change. His findings were published in Proceedings of the National Academies of Sciences. Mr. Love Anderegg found that 97% to 98% of the 200 most prolific writers on climate change believe "anthropogenic greenhouse gases have been responsible for 'most' of the 'unequivocal' warming." There was no mention of how dangerous this climate change might be; and, of course, 200 researchers out of the thousands who have contributed to the climate science debate is not evidence of consensus.

In 2013, John Cook, an Australia-based blogger, and some of his friends reviewed abstracts of peer-reviewed papers published from 1991 to 2011. Mr. Cook reported that 97% of those who stated a position explicitly or implicitly suggest that human activity is responsible for some warming. His findings were published in Environmental Research Letters.

Mr. Cook's work was quickly debunked. In Science and Education in August 2013, for example, David R. Legates (a professor of geography at the University of Delaware and former director of its Center for Climatic Research) and three coauthors reviewed the same papers as did Mr. Cook and found "only 41 papers—0.3 percent of all 11,944 abstracts or 1.0 percent of the 4,014 expressing an opinion, and not 97.1 percent—had been found to endorse" the claim that human activity is causing most of the current warming. Elsewhere, climate scientists including Craig Idso, Nicola Scafetta, Nir J. Shaviv and Nils- Axel Morner, whose research questions the alleged consensus, protested that Mr. Cook ignored or misrepresented their work.

Rigorous international surveys conducted by German scientists Dennis Bray and Hans von Storch —most recently published in Environmental Science & Policy in 2010—have found that most climate scientists disagree with the consensus on key issues such as the reliability of climate data and computer models. They do not believe that climate processes such as cloud formation and precipitation are sufficiently understood to predict future climate change.

Surveys of meteorologists repeatedly find a majority oppose the alleged consensus. Only 39.5% of 1,854 American Meteorological Society members who responded to a survey in 2012 said man-made global warming is dangerous.

Finally, the U.N.'s Intergovernmental Panel on Climate Change—which claims to speak for more than 2,500 scientists—is probably the most frequently cited source for the consensus. Its latest report claims that "human interference with the climate system is occurring, and climate change poses risks for human and natural systems." Yet relatively few have either written on or reviewed research having to do with the key question: How much of the temperature increase and other climate changes observed in the 20th century was caused by man-made greenhouse-gas emissions? The IPCC lists only 41 authors and editors of the relevant chapter of the Fifth Assessment Report addressing "anthropogenic and natural radiative forcing."

Of the various petitions on global warming circulated for signatures by scientists, the one by the Petition Project, a group of physicists and physical chemists based in La Jolla, Calif., has by far the most signatures—more than 31,000 (more than 9,000 with a Ph.D.). It was most recently published in 2009, and most signers were added or reaffirmed since 2007. The petition states that "there is no convincing scientific evidence that human release of . . . carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate."

We could go on, but the larger point is plain. There is no basis for the claim that 97% of scientists believe that man-made climate change is a dangerous problem.

The Wall Street Journal denies the 97% scientific consensus on human-caused global warming
The Rupert Murdoch media continues to deny the reality of human-caused global warming

Rupert Murdoch’s The Wall Street Journal editorial page has long published op-eds denying basic climate science. This week, they published an editorial denying the 97% expert scientific consensus that humans are causing global warming. The editorial may have been published as a damage control effort in the wake of John Oliver’s brilliant and hilarious global warming debate viral video, which has now surpassed 3 million views. After all, fossil fuel interests and Republican political strategists have been waging a campaign to obscure public awareness of the expert consensus on global warming for nearly three decades.

The Wall Street Journal editorial was written by Joseph Bast, president of the Heartland Institute political advocacy group of Unabomber billboard infamy, and Roy Spencer of “global warming Nazis” infamy. Spencer previously claimed in testimony to US Congress to be part of the 97% consensus, although his research actually falls within the less than 3% fringe minority of papers that minimize or reject the human influence on global warming.

Spencer’s claim to the contrary was a result of failing to understand the consensus research he referenced. In The Wall Street Journal this week, Spencer and Bast continued that tradition of misunderstanding and misrepresenting the scientific literature on the expert global warming consensus.

For example, in order to reject the findings of the paper my colleagues and I published last year finding a 97% consensus on human-caused global warming in the peer-reviewed literature, Bast and Spencer referenced a critical comment subsequently published by David Legates et al. in an obscure off-topic journal called Science and Education. That paper was based on a blog post written by Christopher Monckton, who's infamous for calling environmental activists “Hitler Youth.”

Monckton's blog post and paper tried to deny the consensus by ignoring 98% of the papers that endorse it. He compared only papers that explicitly quantified the human contribution to global warming to the full sample of all peer-reviewed papers that mention the phrases “global warming” or “global climate change.”

By that standard, there’s less than a 1% expert consensus on evolution, germ theory, and heliocentric theory, because there are hardly any papers in those scientific fields that bother to say something so obvious as, for example, “the Earth revolves around the sun.” The same is true of human-caused global warming. That Bast and Spencer refer to Monckton and Legates’ fundamentally wrong paper in an obscure off-topic journal as “more reliable research” reveals their bias in only considering denial “reliable.”
