‘Doom loops’ are accelerating climate change – but we can break them

Vicious cycles are accelerating climate change. One is happening at the north pole, where rising temperatures caused by record levels of fossil fuel combustion are melting more and more sea ice.

Indeed, the extent of Arctic winter sea ice in March 2025 was the lowest ever recorded. This decline in sea ice means the Earth reflects less of the Sun’s energy back into space. So, more climate change leads to less sea ice – and more climate change.

Human behaviour is not immune to this…
