I love to see papers on wind drought but also because so many models struggle to get the correct rhythm of ENSO + El NiΓ±o is a big influence on extended spells of weak winds, I worry this sort of analysis might still underestimate the risks. Definitely going in my read pile though, thank you.

Prolonged wind droughts in a warming climate threaten global wind power security - Nature Climate Change Prolonged low wind speeds can lead to a strong reduction in wind power generation. Here, the authors show that such wind drought events become more frequent and extended under global warming, threaten...

Expect an increase in the frequency and duration of wind droughts in a world that has a reduced equator-to-pole temperature difference #climate πŸ§ͺ🌊

Good grief. Does anybody understand what the β€œ1 in X” catastrophe is? Maybe we should just forget about the curve-fitting and switch to β€œX times bigger than the previous record”.

After a week of smoke, a look at Canada's approach to fighting wildfires differently Minnesota saw a record-breaking six-day air quality alert due to wildfires burning in Canada sending smoke into the skies. Canada is seeing one of it’s worst wildfire seasons on record.

Great discussion here on the causes of increased smoke in our Minnesota skies.
Wildfires have increased 4X in Canada and the US since the 1970s. πŸ”₯
What changed?
The climate.

Rain At Bristol Speedway Classic Was Well-Predicted. So Why Play? The MLB Speedway Classic baseball game between the Atlanta Braves and Cincinnati Reds was a well-predicted rainfest. So why did they try to play?

My breakdown on the weather and climate information that should have informed MLB on its game between the Reds and Braves at Bristol Motor Speedway last night. Because that was an epic fail. They will try again today

Big El Niños 🌊 usually come with big 🌎 teleconnections.
The one in 2023/24 didn't. Why?
Rainfall anomalies in the tropical Pacific were suppressed due to greater warming in Indian and Atlantic Oceans.

DOE climate report response form We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me. We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

🚨 If you're interested in working on a coordinated response to the DOE climate report, please enter your info on this google form 🚨

Please RT this so as many people see it as possible.

Claim: "Water vapor is a greenhouse gas!"
Reality: Yes, and there's more of it in a warmer atmosphere

-"CO2 is plant food!"
-pretty hard to eat when you're on fire

-"Climate has changed before!"
-We know, we told you that

-"Scientists don't know everything!"
- doesn't mean we know *nothing*

Storm update…

Should get into the northwest metro 9:15-9:30pm, and work through the Twin Cities by 11:00pm-12:00am

Severe risk update: ⚑️
Still high uncertainty when/where storms will blow.
Latest models trending later & further south.
Possible bow after 10 PM south of MSP along I-90?
Still a (lesser?) risk for MSP.
We'll keep watching.
Latest NAM 3k model(19Z) below 7 PM to 2 AM.

Senate budget bill clear rebuke to administration plans to gut science Meanwhile, OPM head says "whatever"

The police made that choice for me, and I’m grateful for them stepping in.

I hadn’t realized how much more help my mom needed than what I could provide.

She’s often not happy in memory care, but she was never happy at her own house prior. I do feel better knowing that she’s safe.

Take care.

I am really struggling to figure out how to get exactly this point across.

Assuming that the future will look like the recent past could actually work pretty well for a good while. And at some point, it will fail catastrophically and wipe you out.

Joe is absolutely right. This tragedy was not caused by inadequate data, poor modeling, or incorrect risk assessments. The old technical solution was flawed but basically correct. It still wasn’t enough.

Yeah, but year after year, the defense (including me one time) kept losing the case! I don’t know what the current win/loss record is, but at the time, it was pretty discouraging for the defense/pro-reality argument…

despite Katherine's kind mention, I'm not really sure there's too much innovative about the insurance industry's approach to weather extremes. But it is true we do worry about the worst of the worst-case scenarios.

just the worst part. "Value" only applies to the cost of rebuilding the structures, not the lives of those people killed by the flood.
