Will it be apocalyptic? Will it be catastrophic? How bad will it get? What phrase can we use and not be exaggerating  ー civilizational collapse? An uninhabitable Earth?   In this direction, I recently read a fantastic Opinion piece in the Proceedings of the National Academy of Sciences (PNAS) by Daniel Steel et al.

But for those without access to this piece, and with similar gnawing questions, here is my attempt to cover their article " Climate change and the threat to civilization ". A sensible vocabulary The authors write, " Although a body of scientific research exists on historical and archaeological cases of collapse, discussi...

Here is a map of the maximum temperature for Wednesday, May 08, 2024. Source: https://climatereanalyzer.org/   If you don't like the resolution (like me), I encourage you to get a better look at: https://climatereanalyzer.org/  Climate Reanalyzer is a pretty handy website with many visualizations available for climate/weather data. To recreate the map above, select Today's Weather Maps → 2 m Temperature  → Max. You could also look at Avg (average for the day), Clim (climatological mean) or Min (minimum for the day) for 2m Temperature. In other categories, you should also look at 2m Temp anomaly, which is basically the difference between the temperature for the selected date and the climatological mean value from 1979-2000. In this map, most of India is covered in white, which indicates maximum temperatures around 45 ℃. (Some technical details and explanations are available at the bottom of this page.)   But all of this is to reaffirm what you already know if you...
