One could pin the birth of the modern environmental movement to the early 20th century when Theodore Roosevelt’s love of nature led to the creation of America’s beautiful national parks, the preservation of land for future generations, and the beginning of a genuine effort to clean our land, water, and air. That agenda, which enjoyed broad support, has since given way to a professional “climate movement” that is obsessed with carbon dioxide emissions and addicted to gloom and doom messaging with little grounding in science.

On The Heartland Institute’s Episode #125 of The Climate Realism Show, we bring back guest Matthew Wielicki, an “earth science professor-in-exile” to talk about how and why a conservationist movement morphed into endless and ever-louder climate hysteria. Heartland’s Jim Lakely, Anthony Watts, and Linnea Lueken will also review the “Crazy Climate News of the Week,” including a new video game where you shoot “climate deniers,” a leftist publication wondering if it is time for the climate movement and media to end its obsession with stopping “climate misinformation” from being spoken, and how your refrigerator is really just a luxury that you should give up to save the planet.
