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.

This week’s Talking Climate is a mega-edition, a deep dive into the hot and contentious topic of AI and climate.

If you’ve been wondering whether AI is a climate villain, a climate tool, or both, this edition’s for you.

As TX heads into what may be the biggest ice storm of the year, let’s get one thing straight before the disinfo starts.

Solar and wind energy operate reliably in far colder places.

The real issue is simple: large parts of the grid are not appropriately winterized. When storms come, they fail.
A screen capture from Wikipedia stating that "Data showed that failure to winterize traditional power sources, principally natural gas infrastructure but also to a lesser extent wind turbines, had caused the grid failure,[15][16] with a drop in power production from natural gas more than five times greater than that from wind turbines."

University partners around the country are launching weather balloons today as part of CUSP-ARR in support of AR-RECON and other field campaigns. Data are being ingested into the operational models for improved predictions!

The largest share of emissions linked to rich individuals comes not from their yachts or jets, but from the production of their businesses, says Tasnia Hussain. They should be taxed on their investments. @katharinehayhoe.com @taxjustice.net @climatedesk.org www.nationalobserver.com/2026/01/19/o...

EPA just made its priorities clear.
Instead of valuing the lives saved by limits on deadly air pollution, the agency has stopped counting those benefits altogether. Now it is only counting what pollution rules cost companies. 😡😡
When profits matter more than people’s lives, public health loses.

Must-read reporting by @virginiagewin.bsky.social on how US federal actions are affecting science.

By pairing the scale of the damage with the very human, personal stories behind the numbers, she paints a powerful and comprehensive picture of just how thoroughly US science is being hollowed out.

When we are panicked about climate change, it can make us feel better to judge others. It’s a coping mechanism that is tragically divisive.

I started seeing this type of thing pop up in my social media comments a couple of years ago and it’s just continued since then 😢

You’ve made assumptions about my choices without asking or understanding them: and you misspelled my name while doing so.

My favourite is when they think I have never heard of natural cycles and I'm like, "how do YOU know about them? Because you heard about them from a scientist!"
