Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.
A team of scientists used a computer model to synthesize mil...
The concentration of heat-trapping CO2 pollution in the atmosphere has passed the 400 parts per million (ppm) threshold in Antarctica for the first time in at least 800,000 years, and possibly as long as four million years, scientists reported this week.
The new measurements, reported by British an...
Norway has agreed on a 2030 target to cut net greenhouse gas emissions to zero, 20 years earlier than the previous deadline, a national assembly official said on Tuesday.
Norway will pay for emission cuts abroad that correspond to its own emissions to reach the target.
Norway set a similar 2030 ca...
Former Secretary of State Hillary Clinton, if elected president, likely wouldn’t prioritize a sweeping rule on climate, her campaign chairman, John Podesta, said Friday.
The front-runner for the Democratic presidential nomination would want to work with Congress on climate action, Podesta said. But...
Last year, global efforts on climate change focused on Paris, where representatives from 195 countries hammered out a landmark agreement to limit warming.
This week, the diplomatic scrum shifts to San Francisco.

Representatives from more than 170 countries met on Earth Day ...
The climate science is uncompromising. We’ve already warmed the earth 1 degree Celsius. And we have enough carbon and methane and other greenhouse gasses in the atmosphere and enough heat in the oceans to warm the earth another half a degree Celsius already. So if we stop all greenhouse gas emi...
The climate talks that concluded last December were a great success, but it will be decades before we can judge whether the Paris Agreement itself is ultimately successful. What can be said is that the accord provides a good foundation for meaningful progress on climate change, and represents a dram...

Greenland's snowy surface has been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows. That trend is likely to continue, with the surface's reflectivity, or albedo, decreasing by as much as 10 percent by ...
Leonardo DiCaprio used his Oscar acceptance speech last night to declare that climate change “is real” and to blast what he called the “politics of greed.”DiCaprio won the Academy Award for best actor for his role in “The Revenant” as a 19th-century frontiersman who is left for dead after being maul...

I’m over Greenland headed home to San Francisco and just got the news that a strong climate agreement has been reached back in Paris. Peeking out the window to see ice caps brought a tear to my eyes, when I realized they don’t actually have to melt.
