    EPA issues greenhouse-gas rules for new factories and more

    EPA released new rules on greenhouse-gas emissions for new power plants, factories and oil refineries — any big new facility, really that emits huge amounts of carbon dioxide, methane, nitrous oxide, or any of several other classes of chemicals. Existing facilities can continue to spew greenhouse gases at current levels.

    Alaskan peatlands expanded rapidly as ice age waned

    The rapid growth of Alaskan wetlands before 8,600 years ago was due to hotter summers and colder winters, which could spell trouble in a warmer world, a new study suggests.

    IPCC looks to vet, report climate-science better

    Major U.S. science organizations aren’t the only ones to realize that the climate-science community has bungled – and badly – its portrayals of research on global change in recent months, if not years, and its responses to criticisms. Yesterday, the Intergovernmental Panel on Climate Change (a group established by the United Nations and World Meteorological Organization) said: “we recognize the criticism that has been leveled at us and the need to respond.” So will be convening an “independent review” panel to investigate what the organization’s procedures should be to vet not only the data it uses and how to synthesize conclusions based on those data, but also how it should convey those conclusions (and any necessary caveats) in reports to the public and policymakers.

    Climate science: Credibility at risk, scientists say

    Publication of hacked emails exchanged by climate scientists. News accounts of problems in vetting data used in climate-assessment reports. Charges by critics that scientists won’t release their raw data so that others might independently vet published analyses of climate trends. Taken together, these events have marred the reputations of climate scientists, the Intergovernmental Panel on Climate Change and perhaps science generally. Or so concluded a distinguished panel of science luminaries.

    Sea levels erratic during latest ice age

    Mineral crusts deposited 81,000 years ago in a Mediterranean island’s caves suggest an abrupt jump in sea level.
