The Big 5 Natural Causes of Climate Change: part 4 Landscape Changes - video Jim Steele
May 23, 2022
In parts 1 thru 3 we detailed how ocean currents warmed the Arctic, how more La Ninas were warming the oceans and affecting jet streams. Here I examine the dynamics that warm the land. Because the degree to which the earth's surface is heated by the sun determines air temperatures, landscape changes like lost wetlands, deforestation, overgrazing and urbanization have all contributed significantly to warming since the Little Ice Age ended. Although most landscape changes are caused by humans, the intent here is show how landscape changes largely account for the land's temperature trends that have been incorrectly blamed on rising CO2. A transcript of this video may be viewed at https://perhapsallnatural.blogspot.co... Jim Steele is Director emeritus of San Francisco State University’s Sierra Nevada Field Campus, authored Landscapes and Cycles: An Environmentalist’s Journey to Climate Skepticism, and proud member of the CO2 Coalition.
