Does the range of plausible temperatures in a next-day forecast translate into any substantial difference in expectations for the day’s energy expenditure? A simple calculation shows that the answer is yes. www.interactivebrokers.com/campus/trade...

There’s a real possibility that Hurricane Erin may still be the only hurricane of the 2025 Atlantic season by the end of next week. As it stands, the market probabilities at ForecastEx appear to be overvaluing the odds of high activity. www.interactivebrokers.com/campus/trade...

Incidentally, I did a little back-of-envelope calculation for folks in my research group.
The value of real estate in the United States is on the order of 60 trillion $. Thus 1.4 trillion $ is about 2.3% of total current real estate value. Since this is over 30 years, that works out to 0.08 % per year loss in real estate value.
The average annual appreciation in the US real estate market is 4.4% per year, so this 0.08 % per year represents a 2% decrease in the growth rate of US real estate value.
They toss off big numbers, but these numbers are all in the noise.

“Los Angeles is burning, and accelerating hydroclimate whiplash is the key climate connection.” That was the first line of the UCLA press release on a recently-published Nature review paper by @weatherwest.bsky.social et al. ... www.breakthroughjournal.org/p/how-much-d...

“Climate whiplash” appears to be a larger advance in climate science marketing than in climate science.

Using our attributions methods (adapted from the study below), we calculate that climate change enhanced wildfire intensity over the LA area by 6% between January 7th-11th. This is assuming a 10% difference in wind speed.

Here's the reality about the #LAFires this week: this isn't the first time ANY of these places have burned. Not even close. In 2018, we mapped CA fire history to look at fire frequency across SoCal. Santa Monica Mtns area burns more than anywhere else -- up to once per decade in a given spot. 🧵
Map showing the number of times a location has burned in SoCal and which kind of fire it was: one burning under Santa Ana winds, or one that was a summer, fuel-driven fire without Santa Ana winds. Malibu area had burned at least 8 times from 1900-2017, and has burned twice now since. Image from Kolden and Abatzoglou (2018): https://www.mdpi.com/2571-6255/1/2/19

Human deaths associated with both cold and hot temperatures have been decreasing over time, and people living in warmer climates are much less sensitive to hot temperatures. This should have implications for adaptation research. My lecture for the Johns Hopkins on this topic: youtu.be/Psgfsa3iEX0
