Top Climate Experts to Follow on Twitter

We’re huge fans of Twitter. But sometimes it’s hard to know who to trust to get the latest on climate science. This list can help.


We get this question a lot here at Climate Reality – “Who should I follow on Twitter for the latest climate and related sciences?”

We don’t blame you. We’re huge fans of Twitter to stay informed on climate news, science reports, and expert opinions. But with 261 million users and 6,000 tweets tweeted every second, it’s easy to get lost in the sea of information and lose sight of what’s really important.

>> Ten of the best tweets on climate change <<

But we’re happy to point you in the right direction – and by that we mean point you to our favorite climate experts to follow on Twitter.

We created a list of 15 people with exciting feeds on climate change. And we promise you’ll want to check out all of them, since we’ve included experts who work on different aspects of the climate crisis – from melting glaciers to climate justice.

We’ve highlighted some below – but don’t forget to read on for the full list!

Michael E. Mann

Twitter is never dull if you follow our friend and collaborator Dr. Michael E. Mann, director of Penn State’s Earth System Science Center and author of several books about climate change, including The Madhouse Effect  (with cartoonist Tom Toles) and The Tantrum that Saved the World (a children’s book). You can count on him for smart commentary on the latest climate news and answers to questions from the public – both climate activists and …errr.. deniers.

Dr. Ayana E. Johnson

Dr. Johnson fell in love with the ocean when she was just five years old during a family vacation in Key West. Her passion led her to become a PhD marine biologist and self-entitled “ocean policy nerd.” She’s now a lecturer on ocean conservation at New York University and the CEO of consultancy Ocean Collectiv. Follow her to understand the connection between the ocean, climate change, and climate justice – or as she puts it, #OceanJustice.

Katharine Hayhoe

This is the perfect account to follow if you want a little bit of everything climate related. Dr. Hayhoe is a well-known climate scientist and the director of Texas Tech University’s Climate Science Center. She covers it all on her Twitter feed – from the latest climate reports to the connection between climate and religion. As a bonus, she tweets whenever there’s a new episode of Global Weirding, the widely popular YouTube series she hosts.

Marshall Shepherd

Dr. Shepherd has some seriously impressive credentials. A former NASA scientist, he currently teaches atmospheric sciences and geography at the University of Georgia. He is the host of The Weather Channel’s podcast Weather Geeks, a Forbes contributor, and a guest on lots of TV shows discussing climate change. And we’re very proud to announce that he will be one of the experts at our upcoming 40th Climate Reality Leadership Corps training in Atlanta, that will focus on environmental justice. Follow him on Twitter for some climate myths debunking and unapologetic jabs at climate deniers.
