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.

Our latest fact brief:

Q: "Is global warming actually happening?"

A: "Yes - Multiple indicators show Earth is warming rapidly. [...]"

“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.”

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.

Our latest fact brief:

Q: "Are human CO2 emissions driving current global warming?"

A: "Yes - While many natural factors influence Earth’s climate, human emissions of heat-trapping carbon dioxide are driving today’s global warming. [...]"

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.

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...

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:

June 21 is #showyourstripes day and we encourage everybody to join and start conversations about climate risks and solutions with the help of the icon graphic created by @edhawkins.org in 2018, inspired by a blanket crocheted by @elliehighwood.bsky.social

If you are shocked, alarmed, or disappointed about the news that Climate.gov has been effectively shut down with the firing of its content team, here are some things you can do to help! (1/6) 🧪

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.

We also have a short fact brief to answer 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."

Our latest fact brief:

Q: "Are CO2 measurements reliable?"

A: "Yes - Measurements of the amount of carbon dioxide in the atmosphere are consistent, reliable, and globally verified across multiple independent systems. [...]"
