As we head into COP29 in oil-and-gas-rich Azerbaijan with the UN warning we are on course for up to 3°C of temperature rise, climate scientists are urging governments to focus on cryosphere. The frozen regions of our planet are warming several times faster than the global average. If the nations of the world cannot agree on measures to hold global warming to a maximum of 1.5°C, the experts warn of potentially devastating and irreversible impacts from cryosphere melt, not just for the icy north, but for the whole planet.
