While the results of the trial in New York state are promising for this carbon-removal technique,…

A continent-like shelf beneath the Martian surface hints that a vast ocean once covered up to a third of Mars, reshaping the long-running debate over its watery past. This artist’s impression shows how Mars may have looked about 4 billion years ago. Image credit: M. Kornmesser / ESO. While it is widely accepted that Mars…
The seas around Antarctica might begin releasing CO2 Nigel Killeen/Getty Images Global warming caused by humanity’s carbon emissions has been slowing the Atlantic Meridional Overturning Circulation (AMOC), a system of currents including the Gulf Stream that warms Europe. If the AMOC collapsed entirely, it could release massive amounts of carbon from the deep Southern Ocean…
Visualisation showing the western boundary currents that form part of the Atlantic Meridional Overturning Circulation NASA’s Scientific Visualization Studio Buoy measurements show the Atlantic Meridional Overturning Circulation, which moderates Europe’s climate, is weakening at four different latitudes, the strongest evidence so far that this system of ocean currents is slowing and could be heading toward…
