About 150,000 penguins have perished in Antarctica after a huge iceberg cut off their access to the sea, forcing them to trek dozens of kilometers to find food. Scientists warn the birds could be gone within 20 years.
Soil frost is a nearly universal process in the Arctic. In a recent dissertation by doctoral student Marina Becher at Umeå University, it is shown that the frequency and extent of soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil.
It’s vast, frozen and 4000km away at the very bottom of the world. But what’s happening there could affect us all.
