We can now only watch as West Antarctica’s ice sheets collapse

Antarctic climate science is having a moment – a worrying moment. Three new studies have all concluded that the West Antarctic Ice Sheet has begun to collapse. This collapse will impact humanity for generations…

Melting glaciers deform the Earth’s mantle and crust

The significant retreat of elements of the West Antarctic ice sheet such as the Thwaites glacier recently reported in the journal Science suggests a possible sea level rise of 3 to 3.7m. This is a huge…

Greenland ice sheet is melting at an accelerating rate

Warming in the Arctic has now reached the northernmost sections of the Greenland ice sheet. After a long period of stability (more than 25 years), we have found in a new study of the region that the northeast…

What lies beneath … evidence of life under the Antarctic ice

That extreme lifeforms might exist in the cold and dark lakes hidden kilometres beneath the Antarctic ice sheet has fascinated scientists for decades. Understanding how life can exist in the most extreme…

The inevitability of sea level rise

Small numbers can imply big things. Global sea level rose by a little less than 0.2 metres during the 20th century – mainly in response to the 0.8 °C of warming humans have caused through greenhouse gas…
