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.

There absolutely is a way! Climate change affects every single bread and butter issue. From fertility risks to the price of chocolate.

My TED talk explains more, and then every week I have a newsletter that makes this connection!

The most important thing you can do to fight climate change: talk about it

How do you talk to someone who doesn't believe in climate change? Not by rehashing the same data and facts we've been discussing for years, says climate scientist Katharine Hayhoe. In this inspiring, ...

Have you heard about this?

"As the govt shutdown drags on, buildings at NASA's Goddard Space Flight Center (HQ for the Webb telescope among other missions) are being emptied without notice. Highly specialized equipment is at risk of being thrown away like trash."

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.

Fung-wong: Super typhoon hits Philippines as nearly a million evacuate

Typhoon Fung-wong, with sustained winds of 185 km/h (115mph), made landfall on Sunday evening local time.

Unf, shaming individuals is not going to catalyze the long-term action we need. Today, we can direct them to options that still fulfill their perceived needs at much lower impact. But an even better option is to advocate for policies that make the best choice also the most affordable and easiest!

Typhoon FUNG-WONG is heading to the Philippines as the equivalent of a major Atlantic hurricane.
What’s really stands out is its immense eye. At one point today its eye spanned ~70 miles - about the distance from Tampa to Orlando. Picture an eye like that spanning the state!… 1/
