Climate change: Big changes for big mammals
Jan 23rd
in mammal responses to climate change
If you were a shrew snuffling around a North American forest, you would be 27 times less likely to respond to climate change than if you were a moose grazing nearby.
That is just one of the findings of a new University of Colorado Boulder assessment led by Assistant Professor Christy McCain that looked at more than 1,000 different scientific studies on North American mammal responses to human-caused climate change. The CU-Boulder team eventually selected 140 scientific papers containing population responses from 73 North American mammal species for their analysis.
The studies assessed by the team examined seven different responses to climate change by individual mammal species: local extinctions of species known as extirpations, range contractions, range shifts, changes in abundance, seasonal responses, body size and genetic diversity. The researchers used statistical models to uncover whether the responses of the 73 mammals to a changing climate were related to aspects of their physiology and behavior or the location of the study population.
The analysis showed only 52 percent of the mammal species responded as expected to climate change, while 7 percent responded the opposite of expectations and the remaining 41 percent had no detectable response. The two main traits tied to climate change responses in the CU-Boulder study were large mammal body size and restricted times during a 24-hour day when particular mammal species are active, she said.
A paper on the study by McCain and former CU-Boulder postdoctoral fellow Sarah King was published online Jan. 22 in the journal Global Change Biology. The National Science Foundation funded the study. King is currently a research associate at Colorado State University.
While body size was by far the best predictor for response to climate change — almost all of the largest mammals responded negatively — the new study also showed that mammals active only during the day or only at night were twice as likely to respond to climate change as mammals that had flexible activity times, she said.
“This is the first time anyone has identified specific traits that tell us which mammals are responding to climate change and which are not,” said McCain of CU-Boulder’s ecology and evolutionary biology department.
McCain said she and King were surprised by some of the findings. “Overall the study suggests our large, charismatic fauna — animals like foxes, elk, reindeer and bighorn sheep — may be at more risk from climate change,” she said. “The thinking that all animals will respond similarly and uniformly to temperature change is clearly not the case.”
The researchers also found that species with higher latitudinal and elevation ranges, like polar bears, American pikas and shadow chipmunks, were more likely to respond to climate change than mammals living lower in latitude and elevation. The ability of mammals to hibernate, burrow and nest was not a good predictor of whether a species responded to climate change or not. American pikas have been extirpated from some of their previously occupied sites in the West, as have shadow chipmunks, which are in decline in California’s Yosemite National Park.
One of the most intriguing study findings was that some small mammals may shelter from climate change by using a wider array of “micro-climates” available in the vegetation and soil, she said. McCain compared the findings with the events at the K-T boundary 66 million years ago when an asteroid smacked Earth, drastically changing the climate and killing off the big dinosaurs but sparing many of the small mammals that found suitable shelter underground to protect them from the cataclysmic event.
“I think the most fascinating thing about our study is that there may be certain traits like body size and activity behaviors that allow some smaller mammals to expand the range of temperature and humidity available to them,” said McCain, also a curator of vertebrate zoology at the University of Colorado Museum of Natural History. “These areas and conditions are not available to bigger mammals that live above the vegetation and experience only ambient temperatures.”
The new study builds on a growing body of global information documenting the shifting behaviors and environments of organisms like flowers, butterflies and birds in response to a warming world, said McCain.
“If we can determine which mammals are responding to climate change and the ones that are at risk of disappearing, then we can tailor conservation efforts more toward those individual species,” said McCain. “Hopefully, this potential loss or decline of our national iconic mammals will spur more people to curb climate impacts by reducing overuse of fossil fuels.”

CU: Gas-fired plants help clean the air
Jan 10th
Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis accepted for publication Jan. 8 in Earth’s Future, a journal of the American Geophysical Union. The so-called “combined cycle” natural gas power plants also release significantly less nitrogen oxides and sulfur dioxide, which can worsen air quality.
“Since more and more of our electricity is coming from these cleaner power plants, emissions from the power sector are lower by 20, 30 even 40 percent for some gases since 1997,” said lead author Joost de Gouw, an atmospheric scientist with NOAA’s Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder. NOAA is the National Oceanic and Atmospheric Administration.
De Gouw, who works at NOAA’s Earth System Research Laboratory (ESRL), and his NOAA and CIRES colleagues analyzed data from systems that continuously monitor emissions at power plant stacks around the country. Previous aircraft-based studies have shown these stack measurements are accurate for carbon dioxide (CO2) and for nitrogen oxides and sulfur dioxide. Nitrogen oxides and sulfur dioxide can react in the atmosphere to form tiny particles and ozone, which can cause respiratory disease.
To compare pollutant emissions from different types of power plants, the scientists calculated emissions per unit of energy produced, for all data available between 1997 and 2012. During that period of time, on average:
- Coal-based power plants emitted 915 grams (32 ounces) of CO2 per kilowatt hour of energy produced;
- Natural gas power plants emitted 549 grams (19 ounces) CO2 per kilowatt hour; and
- Combined cycle natural gas plants emitted 436 grams (15 ounces) CO2 per kilowatt hour.
In combined cycle natural gas plants, operators use two heat engines in tandem to convert a higher fraction of heat into electrical energy. For context, U.S. households consumed 11,280 kilowatt hours of energy, on average, in 2011, according to the U.S. Energy Information Agency. This amounts to 11.4 metric tons per year of CO2 per household, if all of that electricity were generated by a coal power plant, or 5.4 metric tons if it all came from a natural gas power plant with combined cycle technology.
The researchers reported that between 1997 and 2012, the fraction of electric energy in the United States produced from coal gradually decreased from 83 percent to 59, and the fraction of energy from combined cycle natural gas plants rose from none to 34 percent.
That shift in the energy industry meant that power plants, overall, sent 23 percent less CO2 into the atmosphere last year than they would have, had coal been providing about the same fraction of electric power as in 1997, de Gouw said. The switch led to even greater reductions in the power sector’s emissions of nitrogen oxides and sulfur dioxide, which dropped by 40 percent and 44 percent, respectively.
The new findings are consistent with recent reports from the Energy Information Agency that substituting natural gas for coal in power generation helped lower power-related carbon dioxide emissions in 2012.
The authors noted that the new analysis is limited to pollutants emitted during energy production and measured at stacks. The paper did not address levels of greenhouse gases and other pollutants that leak into the atmosphere during fuel extraction, for example. To investigate the total atmospheric consequences of shifting energy use, scientists need to continue collecting data from all aspects of energy exploration, production and use, the authors concluded.
Authors of the new paper, “Reduced Emissions of CO2, NOx and SO2 from U.S. Power Plants Due to the Switch from Coal to Natural Gas with Combined Cycle Technology,” are de Gouw (CIRES), David Parrish (NOAA ESRL), Greg Frost (CIRES) and Michael Trainer (NOAA).

Climate Protection: The New Insurgency
Dec 31st
Faced with the failure of conventional lobbying, the climate protection movement is now turning to mass civil disobedience—but we can take it further still.
By Jeremy Brecher, December 10, 2013.
This article is a joint publication of Foreign Policy In Focus and TruthOut. For a longer presentation, see the Foreign Policy In Focus report, “A Nonviolent Insurgency for Climate Protection?“
When 30 climate protestors from 18 countries protested drilling at an Arctic oil platform operated by Gazprom, they represented the people of the world taking a symbolic stand against climate destruction, the corporate climate destroyers, and the governments that back them. But the action of the Arctic 30 may be prophetic of something more: The emergence of a global insurgency that challenges the very legitimacy of those who are destroying our planet.
The 2013 Fifth Report of the Intergovernmental Panel on Climate Change confirmed that humans are destroying the earth’s climate. But it also revealed something even more alarming: Twenty-five years of human effort to protect the climate have failed even to slow the forces that are destroying it. On the contrary, the rate of increase in carbon emissions from burning fossil fuels tripled between the release of the first IPCC report in 1988 and today.
Scientists and climate protection advocates once expected that rational leaders and institutions would respond appropriately to the common threat of climate change. As Bill McKibben said of Jim Hansen and himself, “I think he thought, as did I, if we get this set of facts out in front of everybody, they’re so powerful — overwhelming — that people will do what needs to be done.”
It didn’t work. Those who are fighting to save the climate need a new strategy. One such strategy to consider is a global nonviolent law-enforcing insurgency.
A nonviolent insurgency
Insurgencies are social movements, but movements of a special type: They reject current rulers’ claims to legitimate authority. Insurgencies often develop from movements that initially make no direct challenge to established authority but eventually conclude that one is necessary to realize their objectives. To effectively protect the earth’s climate and our species’ future, the climate protection movement may have to become such an insurgency.
The term “insurgency” is generally associated with an armed rebellion against an established government. Its aim may be to overthrow the existing government, but it may also aim to change it or simply to protect people against it. Whatever its means and ends, the hallmark of such an insurgency is to deny the legitimacy of established state authority and to assert the legitimacy of its own actions.
A nonviolent insurgency pursues similar objectives by different means. Like an armed insurgency, it does not accept the limits on its action imposed by the powers-that-be. But unlike an armed insurgency, it eschews violence and instead expresses power by mobilizing people for various forms of nonviolent mass action.
After closely following the massive strikes, general strikes, street battles, peasant revolts, and military mutinies of the Russian Revolution of 1905 that forced the czar to grant a constitution, Mohandas (not yet dubbed “Mahatma”) Gandhi concluded, “Even the most powerful cannot rule without the cooperation of the ruled.” Shortly thereafter he launched his first civil disobedience campaign, proclaiming “We too can resort to the Russian remedy against tyranny.”
The powers responsible for climate change could not rule for a day without the acquiescence of those whose lives and future they are destroying. They are only able to continue their destructive course because others enable or acquiesce in it. It is the ordinary activity of people — going to work, paying taxes, buying products, obeying government officials, staying off private property — that continually re-creates the power of the powerful. A nonviolent climate insurgency can be powerful if it withdraws that cooperation from the powers-that-be.
Why a law-enforcing insurgency?
Faced with the failure of conventional lobbying and political “pressure group” activity, much of the climate protection movement is now turning to mass civil disobedience, as witnessed by the campaigns against the Keystone XL pipeline, mountaintop removal coal mining, coal-fired power plants, and Arctic oil drilling. Such civil disobedience, while generally recognizing the legitimacy of the law, refuses to obey it in specific instances.
Civil disobedience represents moral protest, but it does not in itself challenge the legal validity of the government or other institutions against which it is directed. Rather, it claims that the obligation to oppose their immoral actions — whether discriminating against a class of people or conducting an immoral war or destroying the climate — is more binding on individuals than the normal duty to obey the law.
A law-enforcing insurgency goes a step further. It declares a set of laws and policies themselves illegal and sets out to establish law through nonviolent self-help. Such insurgents view those who they are disobeying as merely persons claiming to represent legitimate authority — but who are themselves violating the law under what’s known as “color of law,” or the false pretense of authority. So “civil disobedience” is actually obedience to law and a form of law enforcement.
Social movements that engage in civil disobedience often draw strength from the claim that their actions are not only moral, but that they represent an effort to enforce fundamental legal and constitutional principles flouted by the authorities they are disobeying. And they strengthen a movement’s appeal to the public by presenting its action not as wanton law breaking but as an effort to rectify governments and institutions that are themselves in violation of the law.
For the civil rights movement, the constitution’s guarantee of equal rights meant that sit-inners and freedom riders were not criminals but rather upholders of constitutional law. For the struggle against apartheid, racism was a violation of internationally guaranteed human rights. For war resisters from Vietnam to Iraq, the national and international laws forbidding war crimes defined civil disobedience not as interference with legal, democratic governments but rather as a legal obligation of citizens. For the activists of Solidarity, the nonviolent revolution that overthrew Communism in Poland was not criminal sedition but an effort to implement the international human and labor rights law ratified by their own government.
These examples seem paradoxical. On the one hand, the movement participants appear to be resisting the constituted law and the officials charged with implementing it. On the other, they are claiming to act on the basis of law — in fact to be implementing the law themselves against the opposition of lawless states.
Law professor and historian James Gray Pope has developed a concept of “constitutional insurgency” to understand such cases. A constitutional insurgency, or what might be called a “law-enforcing insurgency,” is a social movement that rejects current constitutional doctrine but that “rather than repudiating the Constitution altogether, draws on it for inspiration and justification.” Pope detailed how the American labor movement long insisted that the right to strike was protected by the 13th amendment to the constitution, which forbade any form of “involuntary servitude.” Injunctions to limit strikes were therefore unconstitutional. Although courts disregarded this claim, the radical Industrial Workers of the World told its members to “disobey and treat with contempt all judicial injunctions,” and the “normally staid” American Federation of Labor maintained that a worker confronted with an unconstitutional injunction had an imperative duty to “refuse obedience and to take whatever consequences may ensue.”
Why climate destruction is illegal
The Justinian Code, issued by the Roman Emperor in 535 A.D., defined the concept of res communes (common things): “By the law of nature these things are common to mankind — the air, running water, the sea and consequently the shores of the sea.” The right of fishing in the sea from the shore “belongs to all men.”
Based on the Justinian Code’s protection of res communes, governments around the world have long served as trustees for rights held in common by the people. In U.S. law this role is defined by the public trust doctrine, under which the government serves as public trustee on behalf of present and future generations. Even if the state holds title, the public is the “beneficial owner.” As trustee, the state has a “fiduciary duty” to the owner — a legal duty to act solely in the owners’ interest with “the highest duty of care.” The principle is recognized today in both common law and civil law systems in countries ranging from South Africa to the Philippines and from the United States to India.
On Mother’s Day, 2011, the youth organization Kids vs. Global Warming organized the “iMatter March” of young people in 160 communities in 45 countries, including the United States, Russia, Brazil, New Zealand, and Great Britain. Concurrently, the Atmospheric Trust Litigation Project brought suits and petitions on behalf of young people in all 50 U.S. states to require the federal and state governments to fulfill their obligation to protect the atmosphere as a common property. Speaking to one of the rallies, 16-year-old Alec Loorz, founder of Kids v. Global Warming and lead plaintiff in the Federal lawsuit, said:
Today, I and other fellow young people are suing the government, for handing over our future to unjust fossil fuel industries, and ignoring the right of our children to inherit the planet that has sustained all of civilization. The government has a legal responsibility to protect the future for our children. So we are demanding that they recognize the atmosphere as a commons that needs to be preserved, and commit to a plan to reduce emissions to a safe level.
Loorz concluded: “The plaintiffs and petitioners on all the cases are young people. We are standing up for our future.”
A trustee has “an active duty of vigilance to ‘prevent decay or waste’ to the asset,” according to University of Oregon law professor Mary Christina Wood, whose new book Nature’s Trust: Environmental Law for a New Age lays out the legal basis for the suits. “Waste” means “permanently damage.” If the asset is wasted in the interest of one generation of beneficiaries over future generations, it is in effect an act of “generational theft.”
Although so far the courts have turned down most of these atmospheric public trust suits, the decisions are being appealed. On October 3, 2013, the Supreme Court of Alaska became the first state supreme court to hear such an appeal.
A global climate insurgency
Compelling as the logic of the atmospheric public trust argument may be, it is easy to imagine that many U.S. courts will refuse to force governments to meet such obligations. In a brief to dismiss the Kansas suit, lawyers called the claim “a child’s wish for a better world,” which is not something a court can do much about.
The sad fact is that virtually all the governments on earth — and their legal systems — are deeply corrupted by the very forces that gain from destroying the global commons. They exercise illegitimate power without regard to their obligations to those they claim to represent, let alone to the common rights beneficiaries of other lands and future generations to whom they also owe “the highest duty of care.”
But protecting the atmosphere is not just a matter for governments. Indeed, it is the failure of governments to protect the public trust that is currently prompting the climate-protection movement to turn to mass civil disobedience. Looked at from the perspective of the public trust doctrine, these actions are far from lawless. Indeed, they embody the effort of people around the world to assert their right and responsibility to protect the public trust. They represent people stepping in to provide law enforcement where corrupt and illegitimate governments have failed to meet their responsibility to do so.
When the climate protection movement uses nonviolent direct action to protect the public trust, it is often confronted by government officials acting under color of law to perpetuate climate destruction. The Arctic 30 were held at gunpoint, for example, and charged with piracy. Russian Prime Minister Dmitry Medvedev said, “Concern for the environment must not cover up unlawful actions.” A law-enforcing climate insurgency will answer: Concern for oil company profits must not cover up unlawful government complicity in destroying the atmospheric public trust.
