What does COP26 mean for global glacier and ice sheet change?

Earth’s glaciers and ice caps (here, we differentiate from the two ice sheets, the Antarctic and Greenland ice sheets) are shrinking at an alarming rate. Each year, global glaciers are losing more mass than is being replenished in each accumulation season. 28 trillion tonnes of ice were lost from 1994 to 2017[1], and rates of …

Choosing the future of Antarctica

In a new article in the journal Nature, Stephen Rintoul and colleagues present two very different visions of Antarctica’s future, from the perspective of an observer looking back from 2070. In one vision, humanity continues to exploit Earth’s natural resources (such as fossils fuels) and does little to protect the environment, and in the other, …

Antarctic Ice Cores

Ice cores are the time machines that allow us to investigate past climate. They preserve actual bubbles of air that mean that we can look at past concentrations of greenhouse gases in the atmosphere. They allow us to reconstruct past temperature and precipitation changes, and help us understand relationships between the composition of the atmosphere …
