"China and India formally agreed Tuesday to join the international climate change agreement reached in December in Copenhagen, the last two major economies to sign up."

"One of the stickiest points in international climate change negotiations is how to account for carbon dioxide and other greenhouse gas emissions produced to make goods that are then sold for export."

"Two billion people worldwide do their cooking on open fires, producing sooty pollution that shortens millions of lives and exacerbates global warming. If widely adopted, a new generation of inexpensive, durable cook stoves could go a long way toward alleviating this problem."

"Diplomacy and energy are never far apart in the Persian Gulf. So, as American officials seek new international sanctions against Iran this week, it’s probably wise for them to remember how much the world’s global energy map has changed over the past decade."

"The European Union's development chief may be forced to name and shame France, Germany and Italy for not living up to their aid commitments, contributing to a roughly $17 billion funding gap this year."

"Scientists say global climate change may be contributing to the increased appearance of dead zones in the Pacific, Atlantic, and Indian Oceans where low oxygen levels are damaging the undersea ecosystem."

"French anti-nuclear campaigners claim a new power plant being built in Normandy carries an accident risk of 'Chernobyl proportions'."

The pace at which glaciers are melting in many places around the world from Asia to Alaska. An error in an estimate of Himalayan glacier melting in a 2007 UN report has been seized on by climate change deniers. But the evidence of widespread and rapid glacial melting is overwhelming.

"Climate scientists have long warned that global warming could unlock vast stores of the greenhouse gas methane that are frozen into the Arctic permafrost, setting off potentially significant increases in global warming. Now researchers at the University of Alaska, Fairbanks, and elsewhere say this change is under way in a little-studied area under the sea, the East Siberian Arctic Shelf, west of the Bering Strait."
