Human beings emit over 30 billion tons of carbon dioxide per year. It’s a global problem, connected with sea level rise and changing global temperatures. There have been many calls for reductions in CO2 emissions, but others look to technology to sequester or trap CO2 below the earth’s surface. Ashley Ahearn reports how some of the most promising research in this field is happening in Iceland.

Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years. That despite a gradual cooling trend over that time as the Earth cycled further away from the sun. A new study to be published in Science Magazine concludes that that cooling was reversed because of increased emissions of carbon dioxide and other green house gases. The World’s Katy Clark reports.

In the fight to curb global warming, we’re often encouraged to drive less or use more fuel efficient cars. Well, it turns out that cars aren’t the biggest source of greenhouse gases. Buildings are responsible for roughly half of the total greenhouse gas emissions around the world. There’s a group of architects that’d like to change that. They call themselves ‘Architecture 2030′. Their goal is to make buildings that use no fossil fuels by the year 2030. The World’s Jason Margolis has our story.
