"The Obama Administration has ignored wrenching climate impacts such as ocean acidification in its effort to estimate the cost of carbon emissions, making emissions limits disproportionately expensive, economists say."
"Almost 200 nations meet in Mexico this month to try to agree a "green fund" for poor countries and other steps toward an elusive climate treaty amid warnings that inaction is driving up the costs of tackling global warming."
"States with coastal water that is becoming more acidic because of carbon dioxide should list them as impaired under the Clean Water Act, the U.S. Environmental Agency said."
"At least one energy measure will see congressional action this week, and a handful of hopeful Senate Democrats have lofty plans to cut through the partisan gridlock of recent months to move several climate and energy bills by year's end."
"Not only is Earth's surface warming, but the troposphere -- the lowest level of the atmosphere, where weather occurs -- is heating up too, U.S. and British meteorologists reported on Monday." The findings may put to rest a 20-year-old controversy over differences between satellite and surface measurements of warming.
"At the Seoul G-20 Summit [Friday], leaders of the world's 19 most industrialized nations and the EU said they have made 'substantial progress' toward phasing out fossil fuel subsidies in the 14 months since their decision to do so at last year's G-20 Summit in Pittsburgh, Pennsylvania."
"Leaks from carbon dioxide injected deep underground to help fight climate change could bubble up into drinking water aquifers near the surface, driving up levels of contaminants in the water tenfold or more in some places, according to a study by Duke University scientists."
A record amount of US corn-based ethanol is being exported, despite the PR campaign touting ethanol as a domestic alternative to importing foreign oil. The reason: a Congress-passed tax credit for blending ethanol with gasoline. The credit -- a giveaway adding at least $6 billion to the federal deficit -- is scheduled to expire this year.
"U.N. climate talks starting in Mexico this month will seek a complex set of interlocking deals to slow global warming but will fall well short of a new treaty, the U.N.'s climate chief said on Wednesday."
A new joint study by the World Bank and the U.N. says that the cost of preventing disasters related to climate change would be far less than post-disaster cleanup.
