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.

Climate row: backing for scientists
A distinguished panel of independent scientists has given a resounding vote of confidence in the credibility and integrity of the key studies into climate change that have emerged over the past 20 years from the embattled Climatic Research Unit (CRU) at the University of East Anglia.
The panel, chaired by Lord Oxburgh, a geologist and former rector of Imperial College London, was asked to review the scientific papers and methodology of the CRU following the theft of university emails, the leaking of which suggested a possible conspiracy to subvert data in order to support the case for man-made climate change.
Lord Oxburgh's investigation found no evidence to suggest that the CRU scientists had acted improperly or dishonestly. It found the unit's overall conclusions were sound but it criticised the CRU for not using the best statistical tools to analyse the data -- although this misjudgement did not alter the overall results and conclusions. ...

from Guardian, from Wit's End:
Peruvian glacier split triggers deadly tsunami
A massive ice block broke from a glacier and crashed into a lake in the Peruvian Andes, unleashing a 23-metre tsunami and sending muddy torrents through nearby towns, killing at least one person.
The chunk of ice, estimated at the size of four football pitches, detached from the Hualcan glacier near Carhuaz, about 200 miles north of the capital, Lima, on Sunday. It plunged into a lagoon known as lake 513, triggering a tsunami that breached 23 metre (75ft) high levees and damaged Carhuaz and other villages, according to authorities.
The Indeci civil defence institute said 50 homes and a water processing plant serving 60,000 residents were wrecked. Trout fishermen initially presumed dead survived, leaving one confirmed death.
Authorities evacuated mountain valley settlements fearing that the ice block, measuring 500 metres by 200 metres, could be followed by more ruptures as the glacier melts.... It was the latest evidence that glaciers are vanishing from Peru, which has 70 percent of the world's tropical icefields. They have retreated by 22 percent since 1975, according to a World Bank report, and warmer temperatures are expected to erase them entirely within 20 years. ...

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. ...
