"The weather may not always have been kind to cocoa farmers in West Africa, but until recently it was at least broadly predictable."

"Global warming already is causing suffering and conflict in Africa, from drought in Sudan and Somalia to flooding in South Africa, President Jacob Zuma said on Monday, urging delegates at an international climate conference to look beyond national interests for solutions."

"DURBAN, South Africa — World temperatures keep rising, and are heading for a threshold that could lead to irreversible changes of the Earth, the U.N. weather office said Tuesday."

"AUSTIN, TEXAS — The nuclear disaster in Fukushima, Japan, earlier this year caused many countries to rethink their appetite for nuclear power. It is also, in subtler ways, altering the fraught discussion of what to do with nuclear plants’ wastes."

"The officials from around the world who will gather in South Africa on Monday to convene the latest round of U.N. climate negotiations are facing an uncomfortable fact: The global pact that has dictated greenhouse-gas targets since 1997 may no longer be relevant.

"Namie, JAPAN — Eight months ago, people left this place in haste. Families raced from their homes without closing the front doors. They left half-finished wine bottles on their kitchen tables and sneakers in their foyers. They jumped in their cars without taking pets and left cows hitched to milking stanchions.

Now the land stands empty, frozen in time, virtually untouched since the March 11 disaster that created a wasteland in the 12-mile circle of farmland that surrounds the Fukushima Daiichi nuclear power plant.
