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.
The issue here is that leading climate scientists are saying our current models aren’t accounting for the actual reported climate, and they’re not sure why it’s off. They’re hoping the new NASA climate program will provide more data for the causes. Currently it’s not explainable by CO2 emissions, sulfur from boats, volcanoes, etc, all of which when factored in still don’t account for more than 90% of how much warmer it is getting.
Yes, human caused global warming is real and happening. The big concern right now is it’s happening much faster than expected and we have no good, proven theory as to why. That’s a problem.
