If you're a @drilledmedia.bsky.social listener you know I think social scientists are key sources if we want to understand why governments haven't acted on climate. So imagine my nerd delight to get my hands on an incredible new batch of research on climate obstruction. drilled.media/podcasts/dri...

🌡️ While Europe's #heatwave pushes temperatures above 40°C, today's first session of our training series underlined: #climate #disinformation doesn't just happen, it's a tool used by powerful actors to sabotage #climateaction – and it must be better understood + countered. 1/2

Autocracies often follow a common playbook, built around the “3 Ps”: populism, polarization, and post-truth

This handbook highlights both historic and contemporary measures aimed at attacking scholars, their institutional environments, and their scholarship

With the rampant spread of mis- and disinformation, how can health professionals fight back with the truth? @johnfocook.bsky.social joined @lisapatel.bsky.social for a new episode of Healthy Climate America to explore this question and more.

I was recently invited to participate in an expert meeting on climate misinformation in the U.S. After much thought and talking to colleagues, I regretfully declined. Like many academics, I consider the U.S. not a safe country to visit atm. Sadly the meeting is in-person, no virtual option :-(

In February 2025, @johnfocook.bsky.social gave two webinars for republicEN explaining the scientific consensus on human-caused climate change. The 1st webinar focused on the history of this scientific consensus, the 2nd on the misinformation spread about it.

Cartoon featuring a cranky uncle archetype claiming there's no scientific consensus on climate change, and when confronted with evidence to the contrary then shifting his argument to say that science isn't done by consensus.
