A new study from the University of Alabama in Huntsville addresses the question of how much the Urban Heat Island (UHI) effect is responsible for the higher temperatures at weather stations across the world. Dr. Roy Spencer and Dr. John Christy have spent several years developing a novel method that quantifies, for the first time, the average UHI warming effects related to population density. Their finding: no less than 65% of “runaway global warming” is not caused by our emissions of carbon dioxide, but by the urbanization of the world.

Dr. Spencer will join us to go over his findings. We’ll also cover the Crazy Climate News of the Week, including an absurd new bit of unscientific propaganda from the U.S. Climate Reference Network at NOAA, wonder if the sun is setting on wide-scale solar energy, and discuss how alarmists refuse to see that we live in a climactic “golden age”—and more.

Join Heartland’s Anthony Watts, Linnea Lueken, H. Sterling Burnett, Jim Lakely, and Dr. Roy Spencer LIVE at 1 p.m. ET for Episode #157 of The Climate Realism Show. We’ll be answering questions in the chat for us, and for Dr. Spencer, on the show.
