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.

The best part about #iucncongress is seeing online friends IRL. Who knew @pammcelwee.bsky.social and I were sisters separated at birth? And I’ve been connected with Neeshad Safi of the Arab Youth Climate Movement for years; but getting to talk w him and two new AYCM members? As they say, priceless 💚
Me in front of the convention center holding up my badge. Barb and I at one of the pavilions inside the exhibition hall. With Neeshad and two of the young climate advocates he’s mentoring.

As always, today's issue of my friend @katharinehayhoe.com's newsletter has good climate news, not-so-good news, and info on what you can do to make an actual impact on saving our planet.

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.

Same. This is why I don’t read clifi

Came here to say the same thing 😂

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.

Some of our ocean’s most iconic species are vanishing — whale sharks, oceanic whitetip sharks, manta and devil rays.

I’m sorry, Steven, but that question showed you didn’t read the newsletter!

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:

Which is why I have that list pinned to the top of my profile.

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.

Please join USAA-IPCC and @agu.org next week for a webinar on how to engage with @ipcc.bsky.social reports as an Expert Reviewer! The Special Report on Cities and Climate Change opens for first review on Oct 17 - we'll discuss in our webinar how to register and what makes for good review comments.

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?

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)
