Thank you @maibached.bsky.social! This is the result of a massive effort by @virginiaclimate.bsky.social and an extended network of experts from around the Commonwealth and beyond. We are incredibly excited to share the first of many such assessments for Virginia.
Hazzah! Today, my colleagues at @virginiaclimate.bsky.social released the first-ever Virginia Climate Assessment, a "comprehensive, science-based evaluation of how past, current, and anticipated climate conditions have and will impact Virginia and its people." Please join me in thanking them.

At least 70% of US households are uninsured or underinsured against floods, yet climate change is rapidly increasing the number and severity of flooding in the US. This doesn’t end well for most people—unless we do something about it now.

The latest casualty in Virginia? Solar for All, plus the clean air & water, better health, and local jobs it would have produced.

There's a new 2025 peak demand record in ERCOT: 82,566 megawatts at 4:55 today. Solar provided 30% of the power at that time and wind about 16%; wholesale power was just $22/MWh. No conservation alerts. No energy emergencies. Just abundant, affordable power. #txlege #txenergy

Everyone is acting like US scientists will just go get science jobs elsewhere and sure some will but there are not anywhere close to enough science jobs elsewhere.

The end result of this will be much, much, much less science, not science happening in different places.
People are talking about the imminent brain drain of US researchers to other countries but that’s not the only way it’s going to look. There is going to be a brain drain out of science and into other US sectors. There are a lot of non-science things you can do with a Ph.D.

Tip of the cap to any state proactively working to identify natural hazard risk areas. This is not a trivial exercise, nor one that ends without A LOT of feedback.

Oregon tried creating their own wildfire maps, and then took a step back.

Most climate denial falls into one of five general categories:

It’s not real
It’s not us
It’s not bad
We can’t fix it
It’s too late

Conspiracy theories about secret experiments have been around for decades and they fall solidly into category 2 above: “it’s not us, it’s THEM”

Many states - Texas, Utah - actively participate in weather modification (cloud seeding) to help address water supply issues. The process disperses silver iodide, a substance that encourages ice crystal formation in clouds, increasing precipitation.
