I'll just let Reid Bryson (father of climate science) speak for himself.
There is no question the earth has been warming. It is coming out of the "Little Ice Age," he said in an interview this week.And from an article in May:
"However, there is no credible evidence that it is due to mankind and carbon dioxide. We've been coming out of a Little Ice Age for 300 years. We have not been making very much carbon dioxide for 300 years. It's been warming up for a long time," Bryson said.
"There is very little truth to what is being said and an awful lot of religion. It's almost a religion. Where you have to believe in anthropogenic (or man-made) global warming or else you are nuts."
While Bryson doesn't think that global warming is man-made, he said there is some evidence of an effect from mankind, but not an effect of carbon dioxide.
For example, in Wisconsin in the last 100 years the biggest heating has been around Madison, Milwaukee and in the Southeast, where the cities are. There was a slight change in the Green Bay area, he said. The rest of the state shows no warming at all.
"The growth of cities makes it hotter, but that was true back in the 1930s, too," Bryson said. "Big cities were hotter than the surrounding countryside because you concentrate the traffic and you concentrate the home heating. And you modify the surface, you pave a lot of it."
Bryson didn't see Al Gore's movie about global warming, "An Inconvenient Truth."
"Don't make me throw up," he said. "It is not science. It is not true."
Bryson is a believer in climate change, in that he’s as quick as anyone to acknowledge that Earth’s climate has done nothing but change throughout the planet’s existence. In fact, he took that knowledge a big step further, earlier than probably anyone else. Almost 40 years ago, Bryson stood before the American Association for the Advancement of Science and presented a paper saying human activity could alter climate.
“I was laughed off the platform for saying that,” he told Wisconsin Energy Cooperative News.
“Climate’s always been changing and it’s been changing rapidly at various times, and so something was making it change in the past,” he told us in an interview this past winter. “Before there were enough people to make any difference at all, two million years ago, nobody was changing the climate, yet the climate was changing, okay?”
We ask Bryson what could be making the key difference:
Q: Could you rank the things that have the most significant impact and where would you put carbon dioxide on the list?
A: Well let me give you one fact first. In the first 30 feet of the atmosphere, on the average, outward radiation from the Earth, which is what CO2 is supposed to affect, how much [of the reflected energy] is absorbed by water vapor? In the first 30 feet, 80 percent, okay?
Q: Eighty percent of the heat radiated back from the surface is absorbed in the first 30 feet by water vapor…
A: And how much is absorbed by carbon dioxide? Eight hundredths of one percent. One one-thousandth as important as water vapor. You can go outside and spit and have the same effect as doubling carbon dioxide.
Asked to evaluate the [global warming forecast] models’ long-range predictive ability, he answers with another question: “Do you believe a five-day forecast?”
