Phys.org / We can predict space weather—what if we could also stop it?

The weather on Earth can get pretty messy sometimes. But in space, it can be wild, and the effects can be far-reaching. Solar flares, giant explosions on the sun, can send out streams of energy that block radio communications ...

Phys.org / Rising seas could eventually 'drown' mangroves and release carbon

Mangroves could store less carbon—and even begin releasing it—as sea levels rise, suggests new research in Earth's Future. Mangroves are made up of salt-tolerant plants that grow in coastal areas. They cover less than 1% ...

Phys.org / Arctic river deltas face rising climate pressure while holding vast frozen carbon reserves

Many rivers flow into the Arctic Ocean north of the Arctic Circle—including the Lena in Siberia and the Mackenzie River in Canada. The deltas of these large and small rivers store large amounts of carbon, which is bound there ...
