The Mankato Free Press
---- — A June 1 letter (“Free Press informs on environment”) referenced anthropogenic climate change, a subject I follow.
On June 10 a New York Times article recognized a 15 year warming “plateau.” But to the surprise of almost no one the Times predicted a sharp rise in warming after the plateau. Based on what? More computer models? The mean computer model projections used to forecast future warming do not track with subsequent empirical observations. The warming the models predicted just isn’t happening.
Monthly studies of the global lower atmosphere taken from instruments carried by NOAA satellites demonstrate virtually no sustained warming since before the high school graduating class of 2013 were kindergartners, regardless of what they might have been taught. Moreover, as of 2008 the minuscule concentration of carbon dioxide in the atmosphere was about 40 percent higher than it was before the start of the Industrial Revolution.
Until this science is settled — if it can ever be settled because climate continues to fluctuate naturally — I remain skeptical and lean toward the line of thought that alarmist claims of an anthropogenic global warming crisis are not sufficiently fact based. And as I have written previously, often more political than scientific.
But I understand some are true believers. Though I do not agree with George Orwell’s political convictions, a quotation attributed to him might be worthy of consideration by those true believers as studies continue: “We are all capable of believing things that are not true.”
For those pushing a political agenda maybe something Harry S. Truman said long before the global warming debate took off, so to speak, best describes their tactics: “If you can not convince them, confuse them.”
