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.

    For carbon sequestration, which also needs to happen.

    Agree, but I think virtually all methods typically talked about are nonsense. Using massive fossil resources to design, build, and maintain giant machines or many smaller machines will ultimately do little to slow ecological collapse even if it does reduce carbon somewhat after some years needed to break even on production. The only sequestration method I’ve ever heard about that makes any sense to me is neighborhood scale production and use of biochar (and avoiding buying any sort of purpose made biochar device that required fossil resources to produce and ship to you). I make biochar in my backyard fire pit (which is a low smoke design) with used coffee tins (i.e. trash) and use the resulting biochar and ash in my compost.

    Harm reduction is valid.

    Agree, Any and all scientifically backed methods to allow us time for degrowth should be considered. I’m not convinced nuclear energy should be a significant part of this though, too many downsides and risks.
