It’s a good thing Dave Morrow’s commentary about humans causing climate change “The evidence is clear” (March) was included in the opinion section because it is devoid of facts. One thing is very clear: The people are tired of this nonsense. Opinion polls reveal that “global warming” is last on the list of public concerns. Belief in anthropogenic global warming is dropping faster than the nighttime temperature in Buffalo. Why? Because the facts don’t support
Yes, CO2 is a green house gas. But more than 96 percent of the CO2 emissions on Earth come from natural sources, not from man’s activities. And greenhouse gases are a very minor factor in our planet’s heat retention capacity, compared to water vapor. These are facts.
It is also a fact that the average global temperature decreased from 1940 to 1975 while the atmospheric CO2 concentration was increasing. After a brief warming period we are experiencing this same trend now—temperature decreasing while the CO2 concentration is increasing. If you do read the IPCC reports as Dave suggested you will see that the words “uncertain” and “uncertainty” appear repeatedly. And we are supposed to radically change our use of energy and the world’s economic structure based on this political science? The IPCC process is a sham meant to provide cover for politicians. It should and likely will be disbanded.
