U.N. Panel Issues Its Starkest Warning Yet on Global Warming.

Failure to reduce emissions, the group of scientists and other experts found, could threaten society with food shortages, refugee crises, the flooding of major cities and entire island nations, mass extinction of plants and animals, and a climate so drastically altered it might become dangerous for people to work or play outside during the hottest times of the year.

The new report comes just a month before international delegates convene in Lima, Peru, to devise a new global agreement to limit emissions, and it makes clear the urgency of their task.
