More Debunking Of The Global Warming Hysteria

A new study released this week by the National Center for Policy Analysis, "Climate Science: Climate Change and Its Impacts", is taking the Environazi’s to task once again.  Here is an editorial from the WSJ which breaks it down a bit:

It concludes that "the science does not support claims of drastic increases in global temperatures over the 21rst century, nor does it support claims of human influence on weather events and other secondary effects of climate change."

There are substantial differences in climate models–some 30 of them looked at by the United Nations Intergovernmental Panel on Climate Change–but the Climate Science study concludes that "computer models consistently project a rise in temperatures over the past century that is more than twice as high as the measured increase." The National Center for Atmospheric Research’s prediction of 1.8 degrees Fahrenheit warming is more accurate. In short, the world is not warming as much as environmentalists think it is.

What warming there is turns out to be caused by solar radiation rather than human pollution. The Climate Change study concluded "half the observed 20th century warming occurred before 1940 and cannot be attributed to human causes," and changes in solar radiation can "account for 71 percent of the variation in global surface air temperature from 1880 to 1993."

As for hurricanes, 2005 saw several severe ones–Katrina and Rita both had winds of 150 knots–hitting New Orleans, the Gulf Coast and Florida. But there is little evidence linking them to global warming. A team of National Oceanic and Atmospheric Administration scientists concluded that the increased Atlantic hurricane activity since 1995 "is not related to greenhouse warming" but instead to natural tropical climate cycles.

Regarding Arctic temperature changes, the Study found the coastal stations in Greenland had actually experienced a cooling trend: The "average summer air temperatures at the summit of the Greenland Ice Sheet, have decreased at the rate of 4 degrees F per decade since measurements began in 1987." Add in Russian and Alaskan temperature data and "Arctic air temperatures were warmest in the 1930s and near the coolest for the period of recorded observations (since at least 1920) in the late 1980s."

As for sea ice, it is not melting excessively. Canada’s Department of Fisheries and Oceans concluded that "global warming appears to play a minor role in changes to Arctic sea ice." The U.N.’s IPCC Third Assessment Report concluded that the rate of sea level rise has not accelerated during the last century, which is supported by U.S. coastal sea level experience. In California sea levels have risen between zero and seven millimeters a year and between 2.1 and 2.8 millimeters a year in North and South Carolina.

[…]The Climate Science study concludes that projections of global warming over the next century "have decreased significantly since early modeling efforts," and that global air temperatures should increase by 2.5 degrees and the United States by about 1 degree Fahrenheit over the next hundred years. The environmental pessimists tell us, as in Time magazine’s recent global warming issue, to "Be Worried. Be Very Worried," but the truth is that our environmental progress has been substantially improving, and we should be very pleased.

Meanwhile ANOTHER climate scientist, this time Dr. William Cotton,  has come out in opposition to this man-made global warming hysteria, saying exactly what we have been saying for some time.  We just don’t understand climate enough to predict what will happen 10 years from now, let alone 100.  And there is just no solid evidence to suggest we humans are causing global warming:

“I am not exactly speaking out against global warming. But, I don’t think the science is as solid as many lead us to believe. Don’t get me wrong, the science of how greenhouse gases directly affect climate is strong. But where it gets messy is all the feedbacks in the system that the theory relies upon and most particularly the role of clouds. Also when it comes to future scenarios (predictions?) decades or longer I point out there are many other factors affecting climate and some of these can be quite large but often are not predictable. Many of these are related to aerosols either natural (volcanoes) or manmade. Then there is also the wildcard with respect to solar variability impacting climate. I think there is something going on there that we just don’t understand. I try to keep up on papers in that area and so far am not convinced about their physical arguments especially the cosmic ray/cloud cover arguments But just because we can’t explain it doesn’t mean something important isn’t happening.

I have attached a copy of the recent talk I gave at the University of Tel-Aviv. I didn’t put it on a slide but I also point out that this position is purely from my personal scientific evaluation. My book on “Human Impacts on Weather and Climate,” 2nd Edition by Cotton and Pielke published by Cambridge is out by the way.

I also point out that I am very “green” as I ride a bicycle to and from work 12 miles a day, I have a Toyota Prius, fly a sailplane, sail boats and paddle kayaks, have an electric lawnmower and weedwacker, florescent lights throughout the house, and support reducing pollution of all sorts.

I put the figure showing the correlation between greenhouse gas emissions and population to show that the bottom line is we are overloading our planet and that as long as we keep putting more and more people on it we will be increasing the likelihood of serious impacts on water resources, air quality, and weather and climate. However, as a scientist I have to draw the line between being “objective” and being an advocate of policies.”

Now this is an honest assessment by someone who quite obviously believes humans are impacting the planet, but is not following the money to advocate the man-made global warming industry. 

Because make no mistake about it….

It is a industry…

But at least THIS 15 year old gets it.
