In a new paper, climate scientists at the University of Massachusetts Amherst and Woods Hole Oceanographic Institution propose that massive amounts of melting sea ice in the Arctic drained into the North Atlantic and disrupted climate-steering currents, thus playing an important role in causing past abrupt climate change after the last Ice Age, from about 8,000 to 13,000 years ago.

Climate change, with more and more storms and heat waves, also has consequences for our energy supply. 

Warm air prevailed in the 2019-2020 winter season, preventing much ice from forming on the lakes.

Can you tell if the two marshes shown below are thriving or deteriorating over time?

Delta-X, a new NASA airborne investigation, is preparing to embark on its first field campaign in the Mississippi River Delta in coastal Louisiana.

Rapid Arctic warming has not led to a “wavier” jet stream around the mid-latitudes in recent decades, pioneering new research has shown.

A paper released today by the journal Nature Food presents a new global food system approach to climate-change research that brings together agricultural production, supply chains and consumption.

By measuring the carbon-14 isotope in air from more than 200 years ago, the researchers found that scientists have been vastly overestimating the amount of fossil methane emitted by natural sources, and have therefore been underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels.

Four factors to consider in the race to solve the climate crisis, including how to scale up a tool called negative emissions and why the oceans can only help so much.

The polar vortex usually encompasses the polar region in the winter stratosphere, but sometimes shifts markedly away from its normal position and distorts during stratospheric sudden warmings (SSWs).
