January 11, 2012 Ever wondered who the big greenhouse-gas emitters are in your neck of the woods? The answer is now just a click away.
December 11, 2011 After a third sleepless night, climate negotiators in Durban, South Africa, finally found a way to reach a compromise early Sunday. The agreement charts a course for a legally binding climate pact that would include all the major emitters, including China, the United States and India.
December 8, 2011 Frustrated by what some see as U.S. foot-dragging on climate policy, an American college student interrupted U.S. envoy Todd Stern Thursday during his remarks at the climate conference in South Africa. Later, Stern emphasized that the U.S. has been working hard to advance global climate policy into the 21st century.
December 7, 2011 Fundamental disagreements among the nations attending the U.N. climate conference in Durban, South Africa, may stall a possible deal. There's still no consensus about the best way to move forward with an international agreement to reduce greenhouse gas emissions.
November 28, 2011 A presidential pledge to reduce emissions two years ago went nowhere in Congress. Today, the U.S. is spewing more carbon dioxide than ever into the atmosphere. Without meaningful U.S. action on emissions, a global pact seems unlikely to emerge from U.N. climate talks under way in Durban, South Africa.
November 11, 2011 In addition to carbon dioxide, power plants also spew chemicals like nitrogen and sulfur into the air. This complicated soup actually offsets some global warming by reflecting sunlight into space and pulling carbon dioxide from the air. But the long-term effects of reducing these emissions aren't fully understood.
November 9, 2011 Inventor Michael Laberge is building a machine that aims to generate electricity through nuclear fusion — the same process that powers the sun. His goal is "insanely ambitious": He thinks he can do it using a much cheaper approach than that used by existing multibillion-dollar fusion labs.
October 27, 2011 Increasing U.S. coal exports to China doesn't necessarily mean global emissions will rise. As demand abroad drives up coal prices at home, it could prompt U.S. utilities to switch to cheaper and more environmentally friendly natural gas. And that might alter the politics of climate change in the U.S., an expert says.
