from AP, via PhysOrg:
That 'other' climate problem
Gas locked inside Siberia's frozen soil and under its lakes has been seeping out since the end of the last ice age 10,000 years ago. But in the past few decades, as the Earth has warmed, the icy ground has begun thawing more rapidly, accelerating the release of methane - a greenhouse gas 23 times more powerful than carbon dioxide - at a perilous rate. Some scientists believe the thawing of permafrost could become the epicenter of climate change. They say 1.5 trillion tons of carbon, locked inside icebound earth since the age of mammoths, is a climate time bomb waiting to explode if released into the atmosphere.... Yet awareness of methane leaks from permafrost is so new that it was not even mentioned in the seminal 2007 report by the Intergovernmental Panel on Climate Change, which warned of rising sea levels inundating coastal cities, dramatic shifts in rainfall disrupting agriculture and drinking water, the spread of diseases and the extinction of species.... As the Earth warms, the summer thaw bites a bit deeper, awakening ice-age microbes that attack organic matter - vegetation and animal remains - buried where oxygen cannot reach, producing methane that gurgles to the surface and into the air. The newly released methane adds to the greenhouse effect, trapping yet more heat which deepens the next thaw, in a spiraling cycle of increasing warmth. ...

from Guardian:
Global emissions of carbon dioxide drop 1.3 percent, say international scientists
Global emissions of carbon dioxide dropped by 1.3 percent in 2009 compared with the previous year, largely due to the effects of the economic crisis and an overall fall in GDP, according to an international team of scientists. The drop is smaller than the 2.8 percent fall predicted by many experts for 2009, however, because the reductions in carbon emissions per unit of GDP - a measure of efficiency called the carbon intensity - was smaller than expected in many emerging economies.... Despite the 1.3 percent overall drop, the 2009 global fossil fuel emissions - 30.8bn tons of CO2 - were the second highest in human history, just below the all-time high of 2008. The small overall decrease in global emissions masks some big regional shifts, according to the report published today in Nature Geoscience. Because the global financial crisis has mainly affected developed nations, this is where emissions dropped by the largest amounts: in the US by 6.9 percent, the UK by 8.6 percent, Germany by 7 percent, Japan by 11.8 percent, Russia by 8.4 percent and Australia by 0.4 percent. In the emerging markets, however, there were big increases: China rose by 8 percent, India by 6.2 percent and South Korea by 1.4 percent. ...

from TheEnergyCollective:
Oil industry insider exposé: what it took to wake some of them up on climate.
I've just read Challenged by Carbon: The Oil Industry and Climate Change, which was written by Dr. Bryan Lovell, a former senior executive at British Petroleum.... Lovell writes about how it came to be that the senior European oil executives backed Kyoto while Exxon-Mobil continued on with its denial campaign. In the process, he also shows us what he and his European counterparts believe about how dangerous climate change is. I was astonished.... The oil execs understand and believe that the amount of carbon that is being moved into the atmosphere as civilization accelerates its use of fossil fuels is going in at such a rate that the only comparable event in Earth's history is the PETM (Paleocene-Eocene Thermal Maximum). They believe a recurrence of this event is not only possible but likely. They can't face being held responsible by history. The European senior oil execs, unlike their American counterparts, and perhaps only briefly, lost their nerve about the denial policy, backed Kyoto, and confronted the Americans. The science described by Lovell is why BP started its "Beyond Petroleum" campaign. The science hasn't changed. Obviously, BP has. ...


Hey, you think there'll even be any historians left? Ha! I'm safe.

from National Oceanic and Atmospheric Administration via ScienceDaily:
Earth's Lower Atmosphere Is Warming, Review of Four Decades of Scientific Literature Concludes
The troposphere, the lower part of the atmosphere closest to the Earth, is warming and this warming is broadly consistent with both theoretical expectations and climate models, according to a new scientific study that reviews the history of understanding of temperature changes and their causes in this key atmospheric layer.... The paper documents how, since the development of the very first climate models in the early 1960s, the troposphere has been projected to warm along with the Earth's surface because of the increasing amounts of greenhouse gases in the atmosphere....This new paper extensively reviews the relevant scientific analyses -- 195 cited papers, model results and atmospheric data sets -- and finds that there is no longer evidence for a fundamental discrepancy and that the troposphere is warming. ...

from UC Berkeley News:
Dire messages about global warming can backfire, new study shows
Dire or emotionally charged warnings about the consequences of global warming can backfire if presented too negatively, making people less amenable to reducing their carbon footprint, according to new research from the University of California, Berkeley. "Our study indicates that the potentially devastating consequences of global warming threaten people's fundamental tendency to see the world as safe, stable and fair. As a result, people may respond by discounting evidence for global warming," said Robb Willer, UC Berkeley social psychologist and coauthor of a study to be published in the January issue of the journal Psychological Science. "The scarier the message, the more people who are committed to viewing the world as fundamentally stable and fair are motivated to deny it," agreed Matthew Feinberg, a doctoral student in psychology and coauthor of the study. But if scientists and advocates can communicate their findings in less apocalyptic ways, and present solutions to global warming, Willer said, most people can get past their skepticism. ...
