National Academy of Sciences Goes to War Over CO₂

When five independent scientists dared to produce the first U.S. government report to reject the climate alarmist narrative, Big Climate vowed to strike back. And it has. This week, a group of 85 scientists released a rebuttal to the Department of Energy’s “Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate.” They condemned the report, writing that “no one should doubt human-caused climate change is real,” and attacked the work and motivations of the 2025 Climate Working Group authors: Judith Curry, John Christy, Steven Koonin, Ross McKitrick, and Roy Spencer. We will rebut their rebuttal on Episode 172 of The Climate Realism Show.Join The Heartland Institute’s Anthony Watts, Sterling Burnett, Linnea Lueken, and Jim Lakely, along with special guest Steve Milloy, as they hit this topic, cover the Crazy Climate News of the Week, and answer your questions.

The EPA is moving to rescind the 2009 “endangerment” finding that declared CO₂ a pollutant—supposedly dangerous to human health, well-being, and the planet. Now that the public comment period is open, the National Academy of Sciences is rushing activist scientists into action to defend it. The usual suspects—Michael Mann, Zeke Hausfather, and others—are already whining, while media allies like AP’s Seth Borenstein launch their own attacks.In this episode of The Climate Realism Show, The Heartland Institute’s Anthony Watts, H. Sterling Burnett, Linnea Lueken, and Jim Lakely—joined by returning special guest Chris Martz—dig into the coming “NASty Gram” on CO₂ headed to the EPA. Chris brings his sharp, meteorology-based analysis to cut through the noise and spotlight the facts.We also cover some of the week’s most outrageous climate news: claims that “deniers” are refusing to die from heat waves, a school district ditching electric buses to go back to gas because EVs can’t be repaired, and why climate change isn’t dooming your bananas.Sponsored by Advisor Metals Protect your wealth with precious metals: https://climaterealismshow.com/metals In The Tank broadcasts LIVE every Thursday at 12pm CT on on The Heartland Institute YouTube channel.

During COVID, power‑mad government officials around the globe shut down society to protect us from a contagious virus that killed a small percentage of those who got it. Restaurants, parks, and beaches were closed. Gatherings larger than what could fit in a phone booth were canceled. They even told us not to celebrate Thanksgiving with our loved ones for “the greater good.”Today, power‑grabbers in Canada are banning hikers from the woods in the Maritimes and imposing enormous fines on those who dare set foot in their own public forests. Why? Because of the Canadian wildfires. And this kind of madness is just the beginning.Join The Heartland Institute’s Anthony Watts, Sterling Burnett, Linnea Lueken, and Jim Lakely — along with special guest Matthew Wielicki — to discuss the coming Climate Lockdowns. We will also cover some of the crazy climate news of the week, including rap music being used to raise climate awareness among the illiterate in Pakistan, the continued blackballing of non‑alarmist climate scientists, and how the road to Hell is being paved with green intentions.

A “1,000-year flood.” The hottest temperatures ever recorded! Wildfires “everywhere.” The legacy media and social platforms can’t stop peddling sensational “climate p0rn” — fear-based stories designed to shock, not inform. But behind the dramatic headlines lies a far different reality. This week, we pull back the curtain and show you the hard facts the alarmists leave out.The Heartland Institute’s Anthony Watts, Sterling Burnett, and Jim Lakely dive into Crazy Climate News of the Week:🌍 New evidence revealing just how high atmospheric CO₂ was during the age of dinosaurs🌲 Are claims that climate change is making trees more flammable actually true?⚠️ How the Climate Alarmist Industrial Complex works to crush science and common sense in public policy In The Tank broadcasts LIVE every Thursday at 12pm CT on on The Heartland Institute YouTube channel.

This is a historic week—historically catastrophic for climate alarmists who have bullied their way through every institution in the United States and around the world. Trump’s Environmental Protection Agency formally announced, at long last, that it will repeal the so-called “Endangerment Finding” for carbon dioxide and other greenhouse gases. The EPA has determined that GHGs are not pollution and that their emissions from human activity do not pose a threat to human health. On the same day, Trump’s Department of Energy released a “critical review of impacts of GHG emissions on the U.S. climate.” This marks the first time ever that a climate report from the federal government can withstand scientific scrutiny, as it is based on actual science and data rather than politics or any particular agenda.The Heartland Institute’s Anthony Watts, Sterling Burnett, Linnea Lueken, and Jim Lakely will be joined by Dr. Judith Curry, president of Climate Forecast Applications Network (CFAN). Dr. Curry is one of America's most prominent climate scientists and a co-author of the Department of Energy’s critical review.We will also cover some of the Crazy Climate News of the Week from around the world.

The International Court of Justice at the United Nations this week ruled that failing to take poverty-creating “appropriate action to protect the climate system” — meaning ending the use of life-giving fossil fuels — could open nations to being hauled before a global tribunal to answer for their crimes. As a trio of climate attorneys wrote in The New York Times, “continuing fossil fuel production and use, let alone expanding it, violates the law.” We’ll see about that.But this development is just the latest in a long line of legal actions trying to enforce climate communism, even as more and more countries reject it.The Heartland Institute’s Anthony Watts, Sterling Burnett, Linnea Lueken, Jim Lakely, and our special guest Daren Bakst — director of the Center for Energy and Environment at the Competitive Enterprise Institute — will also cover some of the breaking and Crazy Climate News of the Week from around the world.Thanks to Trump, those gasoline cans everyone hates will no longer be mandatory. We now have only three years left to save the planet, apparently.

The two most important members of the Trump administration reversing years of climate alarmism and junk science in public policy have been crushing it in media appearances. Alarmist outlets like CNN are on the defensive, left with little to say after EPA Administrator Lee Zeldin and Energy Secretary Chris Wright finish with them. Never before have both public policy and public messaging been this coordinated and effective at pushing back against the alarmist narrative. We’ll break it all down.The Heartland Institute’s Anthony Watts, Sterling Burnett, Linnea Lueken, Jim Lakely, and special guest Steve Milloy of JunkScience.com will also cover some of the Crazy Climate News of the Week: Greta Thunberg’s Sweden is backing away from its climate-fighting commitments (with other European countries soon to follow), global warming supposedly makes kids dumber, the carbon footprint of heart surgery is now a “big concern,” and the National Academy of Sciences is throwing a Hail Mary to save the Endangerment Finding for greenhouse gases.

Losing the 2000 election was the best thing to happen to Al Gore. He has since become insanely wealthy and admired around the world by peddling climate alarmism. Hollywood gave him an Oscar for his fictitious documentary An Inconvenient Truth, and (like Michael Mann) he claims to be a Nobel Peace Prize winner for his environmental activism.Yet despite trillions of dollars in propaganda, there’s a sign that Gore’s message of doom is in big trouble: He gave a TED Talk attacking “climate realists” by name. That’s BIG, folks—it shows that the truth, the data, and reality are winning.The Heartland Institute’s Anthony Watts, Sterling Burnett, Linnea Lueken, Jim Lakely, and our special guest Lois Perry, director of Heartland UK/Europe, will cover some of the breaking and crazy climate news of the week from around the world.Antarctica is gaining ice, defying the predictions of climate doomers. A BBC presenter is worried that climate scientists might be a monolithic ideological bloc. An environmental protection charity in Scotland is finally pushing back against wind power because of how it kills threatened bird species. And a “controlled burn” by our government betters turned into a raging inferno at the Grand Canyon that destroyed a historic building.Join us LIVE at 1 p.m. ET on YouTube, Rumble, and X—we’ll answer the questions you leave for our panel in the chat!

The tragedy on the Guadalupe River in Texas is as shocking and sad as it gets. A flash flood took the lives of at least 100 people, including many children, at a popular Christian summer camp held in the floodplain. Climate alarmists and ghoulish politicians were quick to blame both climate change and budget and staffing cuts by President Trump for the loss of life.The truth is, the federal agency responsible for issuing flash flood warnings did its job and confirmed it had sufficient staffing. Flash floods are a regular occurrence in the Texas Hill Country, with that very same floodplain experiencing a similar tragedy in the 1980s. The attempts to politicize this tragedy and use it to advance the climate agenda are disgusting and wrong.On episode #164 of The Climate Realism Show, we bring you the facts.The Heartland Institute’s Anthony Watts, Sterling Burnett, Linnea Lueken, and Jim Lakely will also cover some of the Crazy Climate News of the Week with special guests Myron Ebell and Steve Milloy.What changes are afoot in climate and energy policy thanks to the Big Beautiful Bill signed into law by President Trump on July 4? Why are climate alarmists so obsessed (and wrong) about bees? And Bill Nye is up to his tired old tricks again, blaming the Texas floods on our use of fossil fuels.Join us LIVE at 1 p.m. ET on YouTube, Rumble, and X, and drop your questions in the chat for our panel to answer.

Two of the most prestigious physicists in America have written a new paper explaining why greenhouse gases (GHG) produced by human activity — namely carbon dioxide — cannot cause dangerous warming on the planet. Based on their findings, Dr. Will Happer and Dr. Richard Lindzen urge Congress to repeal all Net Zero subsidies, all laws requiring GHG emission reductions, and all restrictions on fossil fuel development and infrastructure.Our special guest this week is Dr. Will Happer, who will break down how he and Dr. Lindzen reached this conclusion — and why continuing to push Net Zero without scientific justification is a recipe for economic disaster.On Episode #163 of The Climate Realism Show, Dr. Happer joins The Heartland Institute’s Anthony Watts, Sterling Burnett, Linnea Lueken, and Jim Lakely to also cover the Crazy Climate News of the Week.📺 Join us LIVE at 1 p.m. ET on YouTube, Rumble, and X — and drop your questions for Dr. Happer and the panel in the live chat!LINK TO Dr.  Happer's Paper: https://co2coalition.org/wp-content/uploads/2025/06/Lindzen-Happer-GHGs-and-Fossil-Fuels-Climate-Physics-2025-06-07.pdf In The Tank broadcasts LIVE every Thursday at 12pm CT on on The Heartland Institute YouTube channel.
