from Reuters:
Ice cap thaw may awaken Icelandic volcanoes
A thaw of Iceland's ice caps in coming decades caused by climate change may trigger more volcanic eruptions by removing a vast weight and freeing magma from deep below ground, scientists said on Friday. They said there was no sign that the current eruption from below the Eyjafjallajokull glacier that has paralysed flights over northern Europe was linked to global warming. The glacier is too small and light to affect local geology. "Our work suggests that eventually there will be either somewhat larger eruptions or more frequent eruptions in Iceland in coming decades," said Freysteinn Sigmundsson, a vulcanologist at the University of Iceland. "Global warming melts ice and this can influence magmatic systems," he told Reuters. The end of the Ice Age 10,000 years ago coincided with a surge in volcanic activity in Iceland, apparently because huge ice caps thinned and the land rose. ...


All those extra, unnecessary consonants can't be helping the situation!

from CSIRO, via EurekAlert:
Ocean salinities show an intensified water cycle
Evidence that the world's water cycle has already intensified is contained in new research to be published in the American Journal of Climate. The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases.... The paper also confirms that surface warming of the world's oceans over the past 50 years has penetrated into the oceans' interior changing deep-ocean salinity patterns.... The study finds a clear link between salinity changes at the surface driven by ocean warming and changes in the ocean subsurface which follow the trajectories along which surface water travels into the ocean interior. ...


Yes, but are you calculating the salt added from my tears?

from National Center for Atmospheric Research/University Corporation for Atmospheric Research:
'Missing' Heat May Affect Future Climate Change
Current observational tools cannot account for roughly half of the heat that is believed to have built up on Earth in recent years, according to a "Perspectives" article in this week's issue of Science. Scientists at the National Center for Atmospheric Research (NCAR) warn in the new study that satellite sensors, ocean floats, and other instruments are inadequate to track this "missing" heat, which may be building up in the deep oceans or elsewhere in the climate system. "The heat will come back to haunt us sooner or later," says NCAR scientist Kevin Trenberth, the lead author...Whereas satellite instruments indicate that greenhouse gases are continuing to trap more solar energy, or heat, scientists since 2003 have been unable to determine where much of that heat is going. Either the satellite observations are incorrect, says Trenberth, or, more likely, large amounts of heat are penetrating to regions that are not adequately measured, such as the deepest parts of the oceans. Compounding the problem, Earth's surface temperatures have largely leveled off in recent years. Yet melting glaciers and Arctic sea ice, along with rising sea levels, indicate that heat is continuing to have profound effects on the planet. ...


Perhaps that heat we can't account for is being sequestered in skeptics.

from University of Washington via ScienceDaily:
Traumatized Trees: Bug Them Enough, They Get Fired Up
Whether forests are dying back, or just drying out, projections for warming show the Pacific Northwest is becoming primed for more wildfires. The area burned by fire each year is expected to double -- or even triple -- if temperatures increase by about 3.5 degrees Fahrenheit (2 C) in our region, according to University of Washington and USDA Forest Service research... "The difference between now and our prior history is the magnitude of the impact," said Elaine Oneil, UW research associate in forest resources. "We basically have massive bark beetle outbreaks in the western U.S. and Canada over the entire extent of pines that are susceptible. We're seeing these massive mortality events of millions and millions of acres." ...


The trees' trauma may include grief for fallen comrades.

Chicago Lawmakers Propose Tougher Coal-Plant Rules
Chicago lawmakers proposed new clean air regulations Tuesday that they say would be among the toughest in the nation and curb emissions from the city's two coal-burning power plants. Advocates say the two large plants, set in heavily populated South Side neighborhoods, long have been among the city's worst polluters, pumping out thousands of tons of soot and millions of tons of gases linked to global warming. The ordinance would require the Fish and Crawford plants to cut particulate emissions by 90 percent from existing levels by installing modern pollution controls. ...


Now that's my kind of town!

from Guardian:
Confidential document reveals Obama's hardline US climate talk strategy
A document accidentally left on a European hotel computer and passed to the Guardian reveals the US government's increasingly controversial strategy in the global UN climate talks.... Top of the list of objectives is to: "Reinforce the perception that the US is constructively engaged in UN negotiations in an effort to produce a global regime to combat climate change." It also talks of "managing expectations" of the outcome of the Cancun meeting and bypassing traditional media outlets by using podcasts and "intimate meetings" with the chief US negotiator to disarm the US's harsher critics. But the key phrase is in paragraph three where the author writes: "Create a clear understanding of the CA's [Copenhagen accord's] standing and the importance of operationalising ALL elements." This is the clearest signal that the US will refuse to negotiate on separate elements of the controversial accord, but intends to push it through the UN process as a single "take it or leave it" text. The accord is the last-minute agreement reached at the chaotic Copenhagen summit in December. Over 110 countries are now "associated" with the accord but it has not been adopted by the 192-nation UN climate convention. The US has denied aid to some countries that do not support the accord.... It lacks any specific cuts in greenhouse gas emissions and sets a temperature rise limit of 2C, which critics say is too high to prevent serious harm to Africa and other parts of the world. ...


This hard line is thin, and vanishing.
