I’ve written in previous blogs that I think Al Gore and the others who pound the drum of manmade global warming should change the title of their mantra to “climate change.” They would finally be right this if they predict climate change, because the climate has always changed and it always will. The warnings in the 1970s were that man was going to create a global cooling climate disaster. The climate did change, but there was a warming trend instead of the predicted cooling. Some researchers responded by developing computer models that correlated warming temperatures to carbon dioxide concentrations in the atmosphere. They never mention the oceans warm when the sun is more active and carbon dioxide in the atmosphere increases. Man has no control over the warming of oceans that causes higher levels of carbon dioxide in the atmosphere.
A recent Denver Post editorial took both Barrack Obama and Mitt Romney to task for not proposing more aggressive actions to battle climate change. Much of the basis for the editorial is the low level of Arctic ice coverage. The Sea and Ice Data Center indeed does show that ice levels dropped below the average levels and the 2007 levels beginning around the first of August. I expect the Post was also influenced by the record number of over 90 degree days this summer. However, there are other indications that “catastrophic global warming” is not occurring. A web site that has numerous graphs of the average temperature of Gulf of Mexico waters shows 2011 had one of the largest drops in temperature in eighty years.
The book Climatism reviewed on that link of this web site is a good place to start if you want to read details of why man is not the cause of global warming and most if not all of the efforts to develop alternative energy sources are doomed to fail because of simple economics.
Carbon dioxide emissions in the U.S. were at a twenty year low last year because significant amounts of power are being generated with recently inexpensive natural gas. Power generated with natural gas creates half the carbon dioxide compared to coal. One report says that it is expected there will be 175 coal burning plants will be replaced by natural gas plants over the next five years.
Michael Mann of the Earth System Science Center at Penn State University seemed to be grumbling about the improvements created by the shift from dirtier-burning coal to natural gas. He commented that “ultimately people follow their wallets on global warming.” Roger Pielke, Jr., a climate expert at the University of Colorado had a bit different take. He said, “There is a very clear lesson here. What it shows is that if you make a cleaner energy source cheaper, you will displace dirtier sources.”
Some environmentalists aren’t happy about the good news. They don’t like the “fracking” that has resulted in production of huge amounts of natural gas and caused the price of the fuel to drop by more than half. They believe the practice will pollute underground water sources and cause leakage of methane to the atmosphere despite the belief by many government officials that the practice is safe if done properly. My suspicion is that those who are grumbling are mostly worried that there will be even less emphasis on development of expensive solar and wind generated energy. “Installation of new renewable energy facilities has now all but dried up, unable to compete on a grid now flooded with a low-cost, high-energy fuel.” The massively advertised “shift to renewable energy” has added scant amounts of power generation. “Wind supplied less than 3 percent of the nation’s electricity in 2011…and solar power was far less.”
I won’t be in the grumbling camp. I find it refreshing that ingenuity and economics have resulted in improved air quality.
