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.
That’s when it becomes Rita as opposed to “heat Katrina”.
For folks who don’t remember/know about Rita because they didn’t live through it, less than a month after Katrina a record-breaking cat 5 hurricane was heading for Texas. Everyone still had Katrina on their minds and panicked. Millions of people (literally estimated as 2.5–3.7 million) evacuated, or tried.
The highways out of Houston came to a total standstill. About 100 people died before the storm even hit land because of the evacuation. And then the hurricane itself was nbd; the evacuation was literally the worst part.
