Ice rafts traveling farther and faster across the Arctic Ocean

Climate change may be causing Arctic sea ice to travel farther and faster than it did 15 years ago, taking pollutants and other material along for the ride.

Climate

Year in review: Global warming continues apace

New climate research showed that the much-discussed warming hiatus never happened, carbon dioxide levels are higher than ever and Earth is heading toward a new normal.

Climate

195 nations approve historic climate accord

The Paris climate talks end with delegates from 195 nations releasing a hard-fought agreement to curb climate change and limit warming to 2 degrees Celsius.

Climate

Global carbon emissions fell in 2015, despite economic growth

Society’s carbon footprint fell slightly in 2015, largely due to decrease coal consumption in China, researchers report.

Climate

Warming culprit CO₂ has a cool side — and it’s in Antarctica

Rising CO2 levels above central Antarctica cause cooling, not warming, new research suggests. The odd effect results from surface temperatures that are colder than the overlying stratosphere.

Climate

Thinning ice leads to winter warming in the Arctic

Thinning Arctic sea ice could boost heat-trapping water vapor in the air during autumn and winter, leading to more ice loss.

Animals

Getting creative to cut methane from cows

Changing feed, giving vaccines and selective breeding may enable scientists to help beef and dairy cattle shake their title as one of society's worst methane producers.

Climate

Geoengineering is world’s last hope, new book argues

Geoengineering is humankind’s only viable solution to curb climate change impacts, a journalist contends in The Planet Remade.

Climate

Kangaroo farts may not be so eco-friendly after all

Kangaroos fart methane, but not much thanks to the metabolism of gut microbes

Climate

Eocene temperature spike caused by half as much CO₂ as once thought

Revised experiments demonstrate that hot temperatures during the Eocene resulted from lower carbon dioxide concentrations than previously thought.

How to melt an ice cave

Frigid winter air keeps gives ice caves their perpetual chill, researchers find, warning that airtight seals on some ice caves could cause the frigid formations to melt within decades.

Oceans

Rising temperatures complicate efforts to manage cod fishery

Higher water temperatures in the Gulf of Maine could play a role in Atlantic cod crashes.
