I’m a scientist who studies how climate change impacts our lives and the places we love.
Most of us are worried, but many feel stuck on what to do. If that's the way you feel, check out this list below!
We can’t fix it alone, but I know we can together. 💚

The Wreck of the Edmund Fitzgerald was 50 years ago today. Check out the post quoted below that remaps older satellite data and uses ERA5 reanalysis to look back at the #weather on that day. #history 1/2 🧪

Yet another record breaking storm supersized by a warming world 😢
Climate change doesn’t create these storms: it makes them worse. They intensify faster, reach higher strengths and dump more rain.
That’s why climate action isn’t just about saving the planet: it’s quite literally about saving US.
