Ocean Uptake of CO2 Could Drop as We Cut Carbon Emissions

A new study finds that ocean absorption of CO2 rises and falls along with human activity and natural phenomena. The findings are important for understanding how much the oceans will offset future climate change.

How Catastrophic Floods May Have Carved Greenland’s ‘Grand Canyon’

In a new study, researchers propose a mechanism for how mega-canyons under northern Greenland’s ice sheet formed: from a series of catastrophic outburst floods that suddenly and repeatedly drained lakes of meltwater.
