The Atlantic meridional overturning circulation (AMOC), a system of ocean currents that carry warm water from the tropics into the North Atlantic and transport cold water from the northern to the southern hemisphere, is a fundamental mechanism for the regulation of Earth’s climate.

The types of ocean bacteria known to absorb carbon dioxide from the air require more energy – in the form of carbon – and other resources when they’re simultaneously infected by viruses and face attack from nearby predators, new research has found.

Small sulfate particles of diameters 0.4 µm or less from anthropogenic sources could have had a cooling effect on the climate in the 1970s, by triggering cloud formation and reflection radiation.

There’s a freezer door in the mountainside outside of Fairbanks, Alaska. 

Stumbling upon a new source of underwater caffeine was just an added bonus of a new study examining the impact of chemical compounds that corals release into the seawater.

Satellites face greater chances of collision with space debris as a result of reduced density in the upper atmosphere.

New research finds that flooding can affect food security for over 5.6 million people across several African nations.

In a new study, researchers at the Department of Energy’s Pacific Northwest National Laboratory find that the U.S.

By the end of this century, permafrost in the rapidly warming Arctic will likely emit as much carbon dioxide and methane into the atmosphere as a large industrial nation, and potentially more than the U.S. has emitted since the start of the industrial revolution.

A major new project will help benchmark biodiversity change in the Arctic Ocean and guide conservation efforts by identifying unique species and assessing their extinction risk.
