Dirty deeds: The world's biggest polluters by country

US carbon dioxide emissions rose slightly in 2013 following years of decline.

It's cold out. Here's what climate change skeptics have to say about that.

In most of the United States, it's really cold. Really, really, really cold, thanks to something called the "polar vortex." That's not the only chilly news. You might have been following the icy saga of the Akademik Shokalskiy, a ship carrying scientists, journalists, and tourists that got stuck in Antarctic ice on Christmas eve. It's finally been freed by a Chinese icebreaker called the Snow Dragon.  What gives with all this ice in the Antarctic? What's with all this cold outside my house? I thought the world was supposed to be warming!!!

Timeline: President Obama's record on climate change

President Obama announced his new climate change initiative Tuesday at Georgetown University, the first step in what the White House hopes will be a concerted effort to reduce greenhouse gas emissions and increase output of green energy technology. But his administration's climate change record leaves much to be desired.

With annual negotiations on a global climate change in Doha, Qatar just completed, it is clear that the world is failing to meet the challenge to reduce carbon emissions. As countries squabble about low-carbon investment funds, historical responsibility, and “climate compensation,” one proven low-carbon technology is being left out of the discussion: nuclear power.
