Salt marsh carbon may play role in slowing climate warming

A warming climate and rising seas will enable salt marshes to more rapidly capture and remove carbon dioxide from the atmosphere, possibly playing a role in slowing the rate of climate change, according to a new study led ...

Earth's glacial cycles enhanced by Antarctic sea-ice

During past glacial periods the earth was about 6ºC colder and the Northern hemisphere continents were covered by ice sheets up to 4 kilometers thick. However, the earth would not have been so cold, nor the ice sheets so ...

Curbing climate change—why it's so hard to act in time

This summer I worked on the Greenland ice sheet, part of a scientific experiment to study surface melting and its contribution to Greenland's accelerating ice losses. By virtue of its size, elevation and currently frozen ...

Lowering the temperature on a hot topic: A climate change primer

Climate changes. It has done so, often dramatically, over the course of Earth's geologic timescales, measured in hundreds of thousands and millions of years. Some of these changes might have caused a phenomenon called snowball ...
