hi new folks!

I’m a PhD student at UNC Chapel Hill planning studying climate adaptation, (non)migration, and well-being. ⚠️🧪🏡

My current project describes built and behavioral adaptations in rural communities facing chronic coastal flooding. sunny-day-flooding-project.github.io/carteret-flo...
Chronic coastal flooding tolerance in rural North Carolina
We asked rural communities how they are dealing with chronic flooding from changes in tides, wind, and rainfall.

For so long, fossil fuel projects have said their contribution to climate change is "negligible".
Turns out that's wrong.
Our research in NPJ Climate Action proves it.
Every tonne of CO2 matters.

🚨 Important paper in Nature: "Systematic attribution of heatwaves to the emissions of carbon majors".

Systematic attribution of heatwaves to the emissions of carbon majors - Nature
Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

Our lab at Yale literally studies government suppression of outbreak reporting. Please: don't promote unverifiable reports from anonymous accounts. They're very likely to be false, and it boosts unreliable actors. (If this is happening, I suspect CDC sources know how to text a journalist just fine.)
"Just spoke with my CDC sources. They said RFK Jr. has ordered officials to hide tuberculosis cases, even as three active TB cases were just reported in Maine. He's also suppressing bird flu reports. Pandemics don't start with viruses they start with secrecy. RFK Jr. must resign now!"

There is a VERY strong reason to think that moving from private to public insurance will lead to political pressure that keeps premiums artificially low and incentivizes building in the riskiest areas. (See federal flood insurance)

A financial time bomb: the alarming intersection of mortgage lending, physical climate risk, and federal policy. Nonbank lenders financing homes in high-risk areas, GSE privatization retaining an "implied guarantee"--all muting market signals. susanpcrawford.substack.com/p/its-still-...
It's still easy to buy a home in a climate risky area. It's harder to sell it.
Fintech lenders are more likely to approve loans in high climate risk areas, but property values in those areas are dropping.

In a 2000 oral history, one Kerr County resident remembered when his father, in 1959, tried to warn a new resident about building a house close to the river.

“It’s going to surprise newcomers when we get another flood like the ’32 flood," he said.

As this week's heatwave bears down on parts of the US, important to highlight many households in heat-exposed areas either 1. don't have air conditioning, or 2. can't afford to run their ACs.

E.g., in NYC ~10% of households don't have AC. In contrast to...(1/2)
