Let's be serious.

"'The implications of global warming over the coming decades for our industrial economy, water supplies, agriculture, biological diversity and even geopolitics are massive,' said Achim Steiner, the executive director of the United Nations Environment Program. 'This new report should spur policymakers to get off the fence and put strong and effective policies in place to tackle greenhouse gas emissions.”

[Meanwhile, in Washington: The EPA has been closing its research libraries and destroying archived materials on pollution, chemicals and climate... And the US gov't wanted this UN climate report to include a proposal in which giant space mirrors or high-altitude sulfate droplets (more pollutants) could be used to reflect sunlight away from the planet in case greenhouse-gas reductions (that the US hasn't yet committed to) didn't work.]

"The warming and other climate shifts will be highly variable around the world, with the Arctic particularly seeing much higher temperatures, said Susan Solomon, the co-leader of the team writing the summary and the section of the I.P.C.C. report on basic science. She is an atmospheric scientist for the National Oceanic and Atmospheric Administration.

"The kinds of vulnerabilities are very much dependent on where you are, Dr. Solomon said in a telephone interview. 'If you’re living in parts of tropics and they’re getting drier and you’re a farmer there are some very acute issues associated with even small changes in rainfall — changes we’re already seeing are significant,' she said. 'If you are an Inuit and you’re seeing your sea ice retreating already that’s affecting your lifestyle and culture.'

The 20-page summary is a sketch of the findings that are most germane to the public and world leaders.

The full I.P.C.C. report, thousands of pages of technical background, will be released in four sections through the year — the first on basic science, then sections on impacts and options for limiting emissions and limiting inevitable harms, and finally a synthesis of all of the findings near year's end."
