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. 💚
A list of the most effective ways an individual can catalyze change at the scale we need to effectively tackle climate change, based on social science.

Thank you for sharing! I’m sorry this person is already blocked - I can’t speak specifically to why, but most of the people I block here are because they’re so panicked about climate change they decide attacking a climate scientist is the best thing they can do to feel better for a second 😬😢

This quantification method clearly demonstrated that the risks to climate, ecosystems, and human lives posed by individual fossil fuel projects are not 'negligible' but, in fact, 'serious’ threats.

Extreme heat doesn’t just feel exhausting — it ages your body.
A new study shows repeated heatwaves can age you as much as smoking or drinking.
Climate change is literally speeding up our biological clock.

Repeated heatwaves can age you as much as smoking or drinking
Long-term study suggests that the more heatwaves people are exposed to, the more it accelerates body ageing.

I have three copies of Climate Champions by @rachelsarah.bsky.social to give away! I bought a bunch when they came out (I’m in it). This book, targeted at middle and high schoolers, features biographies of a diversity of women working on climate action across disciplines.

Three late November tropical cyclones have devastated cities and villages in countries around the Indian Ocean.

When "a region unused to tropical cyclones has had three in a week, the world needs to ask why this happened, not look away."

It took us a while to determine what they were after, but we figured out that at least the first few rounds of them were trying to get control of large Facebook pages. I’m not sure what the latest iteration is after, but obviously it’s nothing good. 😵‍💫

Just a reminder that if you get an invitation from a relatively well-known person inviting you to be on their podcast and they are offering to pay you: it is a fraud.

I read a lot of fiction, upwards of 200 books a year; but most is deliberately irrelevant to climate, so I didn't recommend any others here. If you want another tho - Victoria Goddard!

(In general I strongly dislike cli-fi so I never read or recommend it. Sorry - just a personal preference.)

For me, 2025 has felt like a particularly heavy year ... and you might feel the same. So as we head into the holiday season, I wanted to share a few recommendations — books, podcasts, and newsletters — that encourage me, make me think, and remind me how hope begins with action.

We also saw massive under-communication in the benefits & accomplishments of carbon pricing in Canada, similar to what happened in the US with the inflation reduction act.

People aren’t going to natively figure out that it’s working & that it’s a good thing. We need to be informed-and we weren’t.

very useful analysis!

I’m not surprised – in Canada, public concern & willingness to vote on climate related issues plummeted after our disastrous wildfire seasons.

I believe what we are seeing is lack of efficacy which is compounded by massive disasters that make people feel even more helpless.

Do climate disasters change us? New research with Hoenow & Karki (RWI Essen) examines Germany's devastating 2021 Ahrtal flood. We'd expect a disaster in your backyard to spark urgent climate action—but does it actually? Our findings: it's complicated. 🧵
