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.

A new study has concluded that solar power plants are now cost-competitive with diesel for many rural Alaska communities, even if solar is only usable during part of the year. (via Alaska Beacon)

Hybrid solar-diesel power is less expensive than diesel alone in parts of rural Alaska, study shows

Diesel prices in remote areas are so high that it’s cheaper to use solar for part of the year, the analysis found, even with the cost of two power plants.

There was a comprehensive analysis by 30 experts supported by Netflix that is currently offline (hopefully back on soon!) - that is the basis for my pinned post. But I bet @kimberlynicholas.bsky.social would have something at her fingertips.

I feel the same and this is exactly why I put so much effort into creating all my starter packs and curating the list of now 4,500 scientists who study climate related topics. It’s hard to start again but I also feel it is worth trying because of all the reasons you say.

You do know that’s fake. I assume you’re sharing it as a joke?

No: I’m a scientist who calculates the numbers.

Right now, fresh ingredients for low carbon diets are usually more expensive and harder to get.

We need to change the SYSTEM so the easiest and most affordable options are also the best for people and the planet.

How? With our voices. Read:

This week, we lost one of the world’s greatest advocates for people and nature. Even in her final days, Dr. Jane Goodall was urging us not to give up, and now her legacy lives on through the countless voices she inspired.

Jane Goodall's final lesson

Honoring Jane Goodall's life, Pope Leo's first climate address, and finding hope in action When I was young, we didn’t have a TV; but every Friday night my mom would bring home movies from the library—sometimes classics like The Sound of Music, but often National Geographic documentaries. The one I remember most vividly featured a young British woman living in Africa, working with chimpanzees.

99.95 of climate denial is solution aversion. What that means is, soon as you respond to one "but what about?" objection, they'll pop right up with a new one.

This video explains, and if you're interested in a deep dive, I have a whole book about this! It's called Saving Us.

If I just explain the facts, they'll get it, right?

Seconded.

Right. See my post about the six most effective science based actions an individual can take above. No thermostat on the list 😄

Please provide a citation for claim number 3: not only for the genetic bias but also for the corollary that this excludes them from engaging in or supporting climate action.

(full disclosure: I don't think the second exists, because climate action can be entirely selfish)

Millions of people using their voices to change the world. That's the only way society has changed before - and that's how I know we can do it again!

My essay here talks about how to link recycling your yoghurt container to catalyzing society-wide change :)

And every week in my newsletter Talking Climate I share good news & not so good news you can use to start a conversation, as well as something concrete you can do to make a difference today.

This week's to-do? Be more like Jane! Jane Goodall, of course :)
