"Are humans responsible for climate change?" recently became fact brief #50 published in collaboration with @gigafactproject.bsky.social and this milestone gave @baerbelw.bsky.social a reason to write a short blog post about the current status of this project: skepticalscience.com/50-fact-brie...

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.” Meet @climate.us: www.theguardian.com/environment/...

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. tamino.wordpress.com/2025/08/03/s...

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.

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: sks.to/sabin33-reca...

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 skepticalscience.com/show-your-st...

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.

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. [...]" sks.to/gfb-co2data?... Full list of fact briefs sks.to/gfb?utm-sour...

Apparently some folks are still confused about how much CO2 in the air has grown due to human activities. It's increased by more than 50%, which means over one third of all CO2 in the air is due to us.

Last week, I was at the General Assembly of the @egu.eu and joined sessions related to (climate) science comms, outreach & policy and had oral presentations in two of them myself about translation activities & collaborations we have at @skepticalscience.bsky.social sks.to/egu25-diary?... #egu25
