Climate collapse is a bigger threat than China and Russia

"Risk" analyzes largely ignore the dangers of the climate crisis. Unless we wake up to them, they will soon overwhelm everyone else. The latest scientific analysis, based on evidence from the last ice age, suggests that there is a possibility that the Amoc could shut down at a surprising rate, and as early as the middle of this century, due to global warming and the subsequent influx of fresh water from the melting Greenland ice sheet.

If that were to happen, the consequences would be catastrophic. With the resulting hypothetical temperature drop of 10 to 15 °C, Britain's climate would change to that of Newfoundland. Agriculture would collapse and the entire landscape would change. Housing and infrastructure would have to be radically adapted to withstand the new climate. (Anatol Lieven, more at theguardian.com)
