Sea Level Mis-information from DOE Here in the USA, the Department of Energy (DOE) has issued a report titled “A Critical Review of the Impacts of Greenhouse Gas Emissions on the U.S. Climate.” It is a product of the &#8…

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:

Warming stripes - global 1850 - 2024

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

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

Live from NASA GISS, kicking-off the Weather and Climate 100-hour livestream YouTube video by The Weather & Climate Livestream

Tune into the 💯 hour Weather & Climate Livestream, brought to you by US meteorologists and climate scientists whose research is at risk due to proposed budget cuts. Learn about the federally funded science that makes weather forecasts and climate predictions possible!

Screenshot of the announcement for the Weather & Climate Livestream: SAVE AMERICA'S FORECASTS Whether it's tomorrow's temperatures or the sea level in fifty years, Americans need to plan for our futures. For generations, the US government has invested in the science that helps us do so, building one of the greatest meteorology and climate science communities in the world. In recent months, this community have been thwarted in our mission of serving the public due to substantial cuts and firings. These actions have already hurt our forecasts, endangering Americans as hurricane season approaches. Legally required assessments of the climate are being stopped, and far more drastic cuts are being proposed. But it's not too late to stop these cuts. Already, public pressure has helped to reopen shuttered weather data centers. To help keep this pressure building, meteorologists and climate scientists from across America want to fulfill our mission by sharing our science with you - so we're coming to your screens, speaking and answering your questions, for over 100 hours, in this science-filled, non-partisan event: The Weather & Climate Livestream From Wednesday, May 28th to Sunday, June 1st, join meteorologists and climate scientists from across the US as we share our work, and show you what makes it so vital. We will clarify the impact of the cuts on this research, and answer your questions about weather and climate research in the US. Information on how to watch is coming soon. If you are a scientist who wants to participate, please visit this speakers page to learn more.

Graph showing clearly that CO2 levels in the atmosphere was flat for thousands of years before the industrial revolution and have now increased by 50% (to over 420 ppm). Over one third of the CO2 in the air is from human activity.

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.

Compilation of impressions from this year's General Assembly of the European Geosciences Union in Vienna.

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
