Global Assessment - Brown Climate Social Science Network Climate advocacy has not failed, climate policy has been sabotaged, explains a new open access book, Climate Obstruction: A Global Assessment.

Proud to have contributed to the blockbuster new volume Climate Obstruction: A Global Assessment, documenting the many, many ways that corporations & orgs try to block climate action. Comprehensive, global in scope, authors from all over the world & the ebook version is FREE cssn.org/news-researc...

Did you see that we resurrected the Fifth National Climate Assessment this week!?

Did you know that we have a $10k match donation challenge live right now?!

Fact: The scientific consensus on climate change is strong, with over 97% of climate scientists agreeing that human activities are the primary driver of global warming.

In the 1st half of 2025, @climate.noaa.gov 's staff were terminated, shutting down daily operations.

Now, former members have joined w/ nonprofit partners to launch Climate.us, where climate info can be safeguarded from politics.

Check out our website and join the effort today.

“This is information that the taxpayers have already paid for,” said @relindsey.bsky.social. “This administration is trying to hide it and take it away from us. It’s an abuse of government. It’s a waste of resources. People should be indignant.”

Notice of Availability: A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate The U.S. Department of Energy (DOE or the Department) seeks public comment on the draft report produced by DOE's Climate Working Group (CWG), titled "A Critical Review of Impacts of Greenhouse Gas Emi...

If you'd like to offer comments on the misleading & error-ridden US federal report, "Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate," the link to do so is below.

Comments are due by Sept 2. Pls see next post for links to resources that debunk the claims in this report.

Is sea level around the US accelerating? If you actually do the analysis, instead of just repeating talking points from decades ago, the answer is yes.

Text from the 1990 global change research act (see link above).

The US Global Change Research Program's website, including all its sub-domains that host the National Climate Assessments and related reports, is now offline.

The 1990 Global Change Research Act (see below) mandates its research findings be available to all federal agencies & departments.

Screenshot of the partial list of Sabin rebuttals showing the first 7 of them all related to solar energy myths.

Since publication, some of the rebuttals have already been updated based on feedback received & 66 links leading to US-government sources in the references were replaced by permanently archived links to avoid link-rot for them if websites are moved or vanish.

All rebuttals: sks.to/sabin33-rebu...

Screenshot of a slide showing composite images of German fact brief and Sabin rebuttal translations.

On top of this collaboration with the Sabin team, German translations of all the rebuttals were created by a class at the Institute for translations at the University Heidelberg. These translations are all available via sks.to/sabin33-rebu...

Creating the rebuttals based on Sabin's report proved to be more complex and timeconsuming than initially thought as it for example entailed reformatting and adapting the ~460 references to our needs and to add many of them to our glossary.

After 33 weeks of highlighting one of the rebuttals to solar, wind and EV myths on Tuesdays, this phase of our successful collaboration with the @sabincenter.bsky.social came to a close recently. We recap the project in this blog post:

Berardelli Bonus: Today I taught a Climate Change 101 Class at USF to seniors A question that came up - Is it possible that global warming is caused by variations in the Sun's energy? Here we plot the changes in solar irradiance (sun's energy that hits the Earth) vs Global temperatures to find out.

Screenshot of fact brief answering the question "Is the sun responsible for global warming?" with "No - Greenhouse gas emissions from human activities, not solar variability, is responsible for the global warming observed since the Industrial Revolution." https://sks.to/gfb-sun
