Doh thanks for letting me know :-(

Why the federal government is making climate data disappear Under Trump, climate denial has given way to something even more dangerous: climate erasure.

Spoke to @katieyoder.bsky.social about the very disturbing development of the Trump administration disappearing climate reports and data, taking climate denial to an unseen level grist.org/language/tru...

The false dichotomy of systemic and individual behaviour change Individuals aren't going to solve climate change, but they are an important part of the system that will get us there.

"you need to make it cheap and easy for people to make the switch. If it’s expensive, most people won’t do it. If it’s difficult or inconvenient, then forget it."

New Handbook Aims to Protect Scientists From Autocratic Threats - Inside Climate News Scientists, experts say, need to help protect democracy, “the system of government in which science, health and humanity are most likely to thrive.”

Great coverage of our Anti-Autocracy Handbook by Bob Berwyn: insideclimatenews.org/news/0407202... . It's difficult to make autocracy seem funny but the White House managed to produce a hilarious comment @ninajankowicz.com @noupside.bsky.social @chrischirp.bsky.social @philippmarkolin.bsky.social

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

A promotional graphic for the Healthy Climate America podcast. At the top, the podcast logo features a green and blue caduceus symbol with the text "Healthy Climate America." Below, two circular headshots are displayed: on the left, Lisa Patel, MD, MESc, labeled as "Host: Lisa Patel, Executive Director, The Medical Society Consortium on Climate & Health," and on the right, John Cook, Senior Research Fellow, Melbourne Center for Behavior Change." White soundwave graphics are in the background. The main text reads: "New Podcast Episode – Teaching the Choir to Sing: How Health Professionals Can Fight Misinformation." At the bottom, a green banner displays "Listen now: bit.ly/HealthyClimateAmerica.

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 :-(

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.

Image showing nine pie-charts depicting nine consensus studies published between 2004 and 2021 100% - Oreskes 2004 97% - Doran 2009 97% - Anderegg 2010 97% - Cook 2013 91% - Verheggen 2014 93% - Stenhouse 2014 97% - Carlton 2015 98% - Myers 2021 99% - Lynas 2021

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 of Erik the Red discovering Greenland and trying to persuade his fellow vikings to settle there.

Cartoon of Erik the Red trying to come up with an enticing name for the icesheet-ridden landmass so people were more likely to move there.

This cartoon parodies the (false) argument that Greenland used to be green so human-caused global warming isn't real. The only relevance it has to recent news is it also involves ridiculous alternative names for Greenland (IMO Icesheetia or Spectaculonia are still better than Red, White & Blueland)

No, this comes from the Cranky Uncle vs. Climate Change book www.amazon.com.au/Cranky-Uncle...

Cartoon: What fossil fuel knew vs. what fossil fuel did

Cartoon of Cranky Uncle holding a groundhog saying “This ground predicts a long winter.” Man says “Scientists say winters are getting warmer.” Cranky Uncle responds “You can’t trust what scientists say.”

My cartoon on the questionable practise of trusting winter predictions to a groundhog when scientists’ climate predictions are called into question. Almost as questionable as my drawing of a groundhog!

Ditto, just followed you :-)

Restoring Freedom Of Speech And Ending Federal Censorship – The White House By the authority vested in me as President by the Constitution and the laws of the United States of America, and section 301 of title 3, United

Seems to me the executive order is against censorship, not against censoring fact-checking (at least for now). So the initial Bsky post citing "claims combatting misinformation are infringements on 1st Amendment" is misrepresenting the EO www.whitehouse.gov/presidential...

Climate misinformation is rife on social media – and poised to get worse Meta’s decision could open the floodgates to more climate misinformation on its apps, including misleading or out-of-context claims during disasters.

Jill Hopke writes on the sad state of affairs on Facebook where the platform opts out of fact-checking so the onus is now on users to push back against misinformation theconversation.com/climate-misi...

Cartoon about being an honest broker between science and denial. Scientist says "2 + 2 = 4". Cranky Uncle says "2 + 2 = 2". Roger Pielke Jr says "2 + 2 = 3"

It's Lindzen. This is my caricature of Pielke (junior, not senior).

Cartoon caricature of John Christy

No, not John Christy. This is my caricature of John Christy from the "97 Hours of Consensus" - which was retweeted by Obama and reached millions of people skepticalscience.com/97-Hours-of-...
