Fear of Global Cooling and Falling Iguanas

A tweet from the National Weather Service in Miami: "Brrr! Much colder temps expected for Christmas. Falling iguanas are possible".  On Christmas Day, the Associated Press reported: "With unexpectedly cold weather in the forecast and pandemic-related curfews. Florida is about to have a Christmas unlike any other in recent memory, and it may involve falling iguanas."  It seems that the lizards which are cold-blooded like to sleep in trees. But when it gets unusually cold their body temperature drops enough, they go sort of dormant. And in losing their grip fall from the branches. Without warning, which was part of the weather alert that temps could be the lowest in some 21 years.  The outstanding climate site WUWT recently ran a list of over 100 climate alarms. These range from dire warnings about another ice age—from using too much fossil fuels—to global warming. For the same reason.

Fear of The World Frying

"The lowest winter temperatures are likely to increase in Northern Europe…The duration of the snow season is very likely to shorten and snow depth is likely to decrease." – IPCC Climate Change, 2007.  "All simulations show the trend of less snowfall will continue into the future. And winter sports will no longer be possible." – Liebnitz Institute for Oceanography, February 17, 2005.  However, this winter seems to be generating some concerning news stories – about too much snow. And even one about too much cold in Brazil. "More Record Lows in Brazil" – Coutiniho, November 7, 2020.  "Snow Chaos – Record Snowfall Causes Mayhem in Austria" – Today, RTZ.Lu, December 9, 2020. "Delhi, Weather: IMD Records Coldest October in 58 Years" – The Quint, October 31, 2020. "Record Snowfall in New York State" – WGRZ.com, December 26, 2020. "Texas Snowfall Almost As Far South As Austin" – NBC, Dallas-Fort Worth, December 28, 2020.

Fear of Another Ice Age

"The world has been chilling sharply…At twice what it would take to put us in an ice Age." – Earth Day 1970, Kenneth Watt, Ecologist. "Discharge into the atmosphere by burning fossil fuel will screen out so much of the sun’s rays that the Earth’s average temperature could fall by six degrees. Sustained emissions over five to ten years, could be sufficient to trigger an Ice Age." – Washington Post, July 9, 1971. Now, just where did the Washington Post sensationalism come from? From a paper published by NASA physicists Rasool and Schneider in 1971:

"For aerosols, however, the net effect of increases in density is to reduce the surface temperature of the Earth. If sustained over a period of several years, such a temperature decrease over the whole globe is believed to be sufficient to trigger an ice age."

In other articles at the time, "aerosols" mainly meant carbon particulates emitted by burning fossil fuels. Indeed, an article published by "New Scientist" in December 2003 quoted James Hansen on increasing amounts of particulate carbon in the atmosphere causing global warming. Hansen, the "father" of global warming hysteria, was quoted: "It causes a strong warming effect". For this old geologist the change from carbon causing cooling to causing global warming with no change in its place in the periodic table has been fascinating. But to go with the mandated fad, global warming due to whatever reason could eventually diminish fears about falling iguanas.
