I am once again begging the New York Times to stop treating a private company’s marketing materials as anything even remotely approaching a scientific consensus
Which is not to say there’s not a consensus that hazards are getting worse or that it will affect insurance rates

I completely agree we should always take a skeptical view of commercial climate risk products AND ALSO acknowledge that it's really freaking hard to correctly take the measure of things we've seen happen either once or never.

Another great post by Bartosz! Definitely also check out his archive, it's full of gems like these. In depth science communication at its best.

Fun little advent challenge! Let's see how far my #rstats skills have come in my two years of use!
This was my tenth(!) year building 25 days of puzzles for #AdventOfCode. You can solve them all for free! Most people write code to solve them, but you can solve them however you like. I hope they help people become better programmers. 🌟
The first puzzle comes out in two hours: adventofcode.com

From my 'to read' backlog, just read this interesting account of the role of the (re)insurance industry in the climate change discourse. I like how it shows the journey of reinsurers from seeing the first signals of CC, to becoming powerful communicators on CC.

Bookkeepers of catastrophes: The overlooked role of reinsurers in climate change debates
Global warming had long been discussed as an abstract matter of physics and chemistry. Only in the 1990s did the more tangible costs caused by natural…

**New Paper Alert**
Thrilled to finally announce the release of our Part 1 paper that re-evaluates and quantifies (normalizes) historical US hurricane losses. This builds upon previous work by introducing counties affected by the radius of maximum wind.
