    IPCC admits Himalayan glacier error

    The Intergovernmental Panel on Climate Change acknowledged today that it had erred in projecting the rate and impacts of retreating Himalayan glaciers in a 2007 report.

    IPCC relied on unvetted Himalaya melt figure

    British newspapers have uncovered what appears to be an embarrassing fact-checking omission by the Intergovernmental Panel on Climate Change, or IPCC. It regards the degree of glacial melting in the Himalayas — information that said parts of the area could be icefree a quarter century from now.

    Climate: Deal or no deal?

    We’ve got a climate accord, President Barack Obama said at a parting press conference tonight (at about 11 to 11:30 p.m. local time, before leaving Denmark). Not so fast, argue a number of other negotiating the G77.

    Climate: China defends its reputation

    Over the past few days, a number of national delegations – not least the United States’ – have criticized implicitly, if not explicitly, China’s unwillingness to accept binding limits on its greenhouse-gas emissions and the measurement of emissions by outside auditors. This morning, Chinese Premier Wen Jiabao addressed a plenary meeting of the United Nations climate-change conference – populated by more than 100 heads of heads of state – to make his case that China has embarked on an earnest step toward substantive climate protection.

    Obama: Climate’s rock star

    A little over a half-hour ago, President Barack Obama wrapped up a stirring pep talk to his fellow world leaders attending the United Nations climate change meeting. He didn’t promise the world. Only that the United States could be depended upon to do its part in helping stem global greenhouse gas emissions and to fund measures that would help fund the world’s poorest and climate-beleaguered nations adapt. But what was especially interesting was to watch how the whole climate conference has waited with baited breath to learn what Obama would say: Could our President make promises that would at last galvanize action in the United States and accord among countries whose views, even yesterday, seemed poles apart?

    Climate emissions mandates: What role China and India?

    One major schism between negotiating blocs at the United Nations climate change meeting is over which nations should face a mandate to reduce their greenhouse-gas emissions. Just the industrial powers that have historically spewed most of the carbon dioxide responsible for today’s climate troubles? Or that group and the newly emerging industrial leaders – especially China, who for several years has reigned as the world’s greenhouse-gas king? The deadline for resolving this dilemma is ostensibly quite imminent. As in today.

    Tiny Tuvalu could quash climate deal

    Prime Minister Apisai Ielemia brags that his tiny 9-island state of Tuvalu is the world’s smallest independent country. Its 10,000 inhabitants live an average of 2 meters above sea level, which makes their homeland highly vulnerable to disappearing with even modest sea-level rise. With the nation’s survival so dependent on climate protection, he vowed today that Tuvalu will not sign onto any climate-change accord that does not require “legally-binding” language and programs aimed at ensuring global temperatures peak at “well below” 1.5 oC. That could effectively torpedo hopes for a climate accord tomorrow when the United Nations climate change meeting is slated to wrap up.
