what makes you think I haven't studied it?

If you'd asked me five years ago if I'd talk about insurance in a climate class AND THE STUDENTS WOULD LIKE IT, I'd say you were nuts.

Reminds me of this comment by Kerry Emanuel

Kerry Emanuel: "If somebody asked me 20 years ago what's a boring profession to go into, I might have said insurance. Boy has that turned out to be wrong."

The Financial Impact of Shifting Hurricanes Patterns in our Changing Climate

Rising climate risks, such as hurricanes along the Gulf and Atlantic Coasts, are putting immense pressure on insurance companies to cover escalating costs. This leaves homeowners and businesses in a precarious situation, teetering on the edge of crisis. Watch this recording of First Street’s webinar to hear from a distinguished panel of experts on hurricane and climate implications. The session will delve into the reasons behind the evolving severity of hurricane patterns, how we can effectively track and measure these changes, and how these increasing climate risks are already leading to significant financial implications for homeowners, businesses, and local economies. The video will cover: - How hurricane patterns have changed over the years and what factors contribute to this change - How to effectively forecast and model future hurricane behaviors and impacts - How increasing climate risk impacts homeowners, local economies, and has national financial implications - The steps regulators and other entities are taking to assess climate risk

I taught a new class on climate risk this fall. One of the things I emphasized was the role of insurance in our economy and how climate change is blowing it up.

In the end of semester evaluations, the students really liked learning about insurance.

• I learned a lot of new things, such as about insurance and energy.
• This course honestly went above and beyond the course objectives, not only did it teach about climate risk but it provided helpful insights into insurance and LLMs which are topics that are very helpful to know and not often taught in other schooling.
• A lot goes into the risk of climate risk that didn't know about. Talking about how insurance plays a role in the whole aspect of the climate changing were my favorite lectures. Talking about LLMs we also interesting because they need to be more understood and I feel like I know a lot more than I used too.

it's hot here, too. it's like something has changed with the climate.

I went to the #bcstx Costco today and put my car sunshade in the windshield to keep the car cool. While 81F in Dec. is actually pretty comfortable, I can't help but think of what those extra degrees of warmth will feel like in August.

#bcstx officially topped off at 81° this afternoon at Easterwood Airport.

We'll put Christmas Eve Eve 2025 in the books as tying for the THIRD hottest December 23rd of record (alongside 1955)

The thing is that they must understand that the DOE CWG report was a dismal failure because it was so bad. This report is going to make the DOE report look like a paradigm of great science.

Andrew Dessler @andrewdessler.com · 5d

The more I think about it ("I'm going to write a National Assessment in a few weeks using AI") the more I think they're just trolling. It's simply not possible.

I'll make a prediction: They will never release any National Climate Assessment.

The next National Climate Assessment will be written by five climate deniers and an AI in a trench coat.

I look forward to the legally required, transparent peer review process required by the US Global Change Research Act and the Information Quality Act. I always thought they would try to do a NCA with Judith Curry, five old men and a LLM.

It’s the gold standard of US climate research. Contrarians could write the next one.

Researchers who have downplayed the threat of global warming have been asked to author the next National Climate Assessment.

They’re not even pretending that it’s for any kind of legitimate reason. Instead, they’re trying to dismantle NCAR to suppress knowledge.

The administration dismantling NCAR is scientific vandalism, much like the Taliban demolishing cultural artifacts.

I came to the US over 10 years ago for a postdoc at NCAR. It changed my life and supercharged my ability to do science. NCAR's unique community nature makes it a global node in atmospheric and climate research. It's really not possible to overstate its value for science and society.

I don’t know how many people came from outside the US.
