Scientists warn the world

With the climate change report:

PARIS, Jan. 29 — Scientists from across the world gathered Monday to hammer out the final details of an authoritative report on climate change that is expected to project centuries of rising temperatures and sea levels unless there are curbs in emissions of carbon dioxide and other gases that trap heat in the atmosphere.

Among the findings in recent drafts:

¶The Arctic Ocean could largely be devoid of sea ice during summer later in the century.

¶Europe’s Mediterranean shores could become barely habitable in summers, while the Alps could shift from snowy winter destinations to summer havens from the heat.

¶Growing seasons in temperate regions will expand, while droughts are likely to ravage further the semiarid regions of Africa and southern Asia.

“Concerns about climate change and public awareness on the subject are at an all-time high,” the chairman of the panel, Rajendra Pachauri, told delegates on Monday.

“We basically have three choices: mitigation, adaptation and suffering,” said John Holdren, the president of the American Association for the Advancement of Science and an energy and climate expert at Harvard. “We’re going to do some of each. The question is what the mix is going to be. The more mitigation we do, the less adaptation will be required and the less suffering there will be.”
