Antarctic areas reach 40C above normal at same time as north pole regions hit 30C above usual levels

Startling heatwaves at both of Earth’s poles are causing alarm among climate scientists, who have warned the “unprecedented” events could signal faster and abrupt climate breakdown.
Temperatures in Antarctica reached record levels at the weekend, an astonishing 40C above normal in places.
At the same time, weather stations near the north pole also showed signs of melting, with some temperatures 30C above normal, hitting levels normally attained far later in the year.
At this time of year, the Antarctic should be rapidly cooling after its summer, and the Arctic only slowly emerging from its winter, as days lengthen. For both poles to show such heating at once is unprecedented.
The rapid rise in temperatures at the poles is a warning of disruption in Earth’s climate systems. Last year, in the first chapter of a comprehensive review of climate science, the Intergovernmental Panel on Climate Change warned of unprecedented warming signals already occurring, resulting in some changes – such as polar melt – that could rapidly become irreversible.
