Temperatures above 50C used to be a rarity confined to two or three global hotspots, but the World Meteorological Organization noted that at least 10 countries have reported this level of searing heat in the past year: the US, Mexico, Morocco, Algeria, Saudi Arabia, Kuwait, Iran, Pakistan, India and China.
In Iran, the heat index – a measure that also includes humidity – has come perilously close to 60C, far above the level considered safe for humans.
Heatwaves are now commonplace elsewhere, killing the most vulnerable, worsening inequality and threatening the wellbeing of future generations. Unicef calculates a quarter of the world’s children are already exposed to frequent heatwaves, and this will rise to almost 100% by mid-century.
Sea levels rising is only one of the concerns. I think the biggest concern is the reduction of ariable land due to climate change. I.e. the carrying capacity of the Earth will decrease (and I’m of the opinion that the human species has already greatly overshot Earth’s carrying capacity; hence the current degradation of our environment).
I think the species will survive, but may experience a population crash (i.e. mass death), and severly reduced quality of life. I think having 1 or 2 kids is fine for now, and hope I’m wrong in my Malthusian-like thinking.
