RE 2: Deceptive Climate Poll should be ignored
Re: "Deceptive climate poll should be ignored," Tom Harris, Opinion, Feb. 27.
How galling that Tom Harris should dismiss climate change without citing a shred of evidence. He asserts "the period around 1970 was the coldest in the last 80 years in the U.S.," but conspicuously fails to note that this cooling was only 0.2 degrees, whereas from 1970 to 2005 there has been a temperature increase of 0.55 degrees. All of the preceding data come from the U.S. National Climate Data Centre.
He asserts "much of the data from cold rural stations was dropped out of the record in the early 1990s." No such statement can be taken seriously until, and unless, he gives the numbers and the source of the information. If anything, with the use of polar orbiting satellites and using radio telemetry for easier to access data from remote stations, the temperature record has never been better.
Harris's insistence that global warming should not be a public policy issue until it is at a "dangerous" level is tantamount to locking the barn door after the horse has been stolen.
He also assures us that the "geological record indicates that it (global warming) was highly unlikely to happen in the foreseeable future."
As the geological record contains no evidence of the impact of an energy-intensive civilization, it is utterly irrelevant to the possibility of global warming in the present century.
There are serious and important questions to be asked about the possibility of global warming, but Harris has not asked a single one.
