Sterling Burnett will discuss the the big white elephant in the climate room: urban heat islands (UHI), a significant but often overlooked topic in climate science. This phenomenon has been known for decades, yet climate advocates often dismiss it as either insignificant or claim to adjust for it when, in reality, they do not.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Joining us will be Dr. Roy Spencer from the University of Alabama in Huntsville. He will talk about his new UHI dataset, which not only demonstrates the strong effect in the United States but also in other parts of the world. He has discovered some remarkable findings that we&#8217;ll illustrate with maps.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tune in to Climate Change Roundtable #87 for a discussion on URBAN HEAT ISLAND EFFECT \u2013 Dramatic New Findings! We&#8217;ll also cover the week&#8217;s crazy climate news and take your questions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;Climate Change Roundtable&#8221; is live every Friday at 12 PM CT\/1 PM ET.
