The Gulf Stream’s tipping point

Back in May, we checked in on the developments in the eastern Pacific’s ocean currents, that we call El Niño. We said that stirrings in the surface suggested there might just be quite a big one. Now, it seems, everyone is talking about it, and it’s definitely big. What is the El ...  Show more

Tom Whipple investigates one of the biggest days in the 10,000 year history of maths. This week, overnight, OpenAI dropped hundreds of mathematical papers onto the internet. From the Margulis-Platonov conjecture to the Gaussian Propeller conjecture to Banach’s simple Lebesgue-spe ...  Show more

A large system of ocean currents known as the Atlantic meridional overturning circulation (AMOC) has been making headlines this week as a new paper predicts its imminent collapse. This could have devastating consequences for the climate. But not all climate scientist and oceanogr ...  Show more

Has the loss from Greenland’s vast ice sheet reached a tipping point? According to glaciologist Michalea King, the rate at which its ice flows into the sea stepped up about 15 years ago. The process of glacial retreat is outpacing the accumulation snow and ice in Greenland’s inte ...  Show more

Record-breaking global temperatures are accelerating Greenland ice melt at an alarming rate. Professor of glaciology Alun Hubbard has witnessed the melt first hand. He tells us how the ice sheet is being destabilised and what this could mean on a human level. Also, how safe are J ...  Show more

Researchers have projected that by the end of the century, days where snow covers the ground will virtually disappear in the ...
