Science doesn’t support current global warming alarms and, even if it did, current proposals to fix things won’t work and might make life worse.No, it's worse than a drug. It's a religion. You can go cold turkey off drugs, but it's a little harder to break the religious hold.
That’s the well-known view of Dr. John Christy, a University of Alabama in Huntsville climate scientist, and Christy spelled out the “whys” and “why nots” of his perspective Tuesday to the Huntsville Rotary Club.
“Consensus is not science,” Christy began, quoting the late author Michael Crichton.
Christy, the state climatologist, is well-known in the global warming debate. He has testified before Congress many times and was an unpaid expert witness for the automobile industry in a federal lawsuit against fleet mileage requirements.
Here’s Christy’s basic argument:
* The data being used to predict catastrophic warming is suspect.
* Models generated from that data “overstate the warming” actually taking place. The earth is warming, but not that much, and it has warmed and cooled for eons.
* The Earth’s atmosphere is nowhere near as sensitive to carbon dioxide as some environmentalists believe.
* Any “solution” to perceived global warming must balance the growing worldwide demand for energy against cutting carbon dioxide output.
Fleet mileage requirements now proposed by the Environmental Protection Agency “would reduce global temperatures by about 1/100th of a degree,” Christy said.
You would need to replace 1,000 coal-fired power plants with 1,000 nuclear plants to change global climate even .15 of a degree, he said.
“This is the scale (of global climate) we are talking about,” Christy said.
* One cost of mandating harsh energy controls is the migration of industry to areas where requirements are less, Christy said.
In his talk, Christy also took aim at several other widely discussed pronouncements.
* Temperatures in the Arctic have increased over the last 100 years, he agreed, but that’s only because 100 years ago “was the coldest it’s been in a long time.”
* Arctic ice has melted, but ice has grown in Anartica. Between the two, there’s about as much ice as always.
* There are more polar bears now, not fewer. Canada issues 800 bear-hunting permits each year, he pointed out.
* Temperatures may be warmer in Greenland, but scientific experiments with ice fields show “that 4,000 years ago, it was warmer in Greenland than it is today.
“Greenland did not melt,” Christy said.
Why is the apocalyptic view of climate change so widespread?
“Funding comes if you have an alarming story,” Christy said.
He also cited “group think” and said scientists revel in the attention their views about climate brings.
“It’s almost a drug,” Christy said.

Science Doesn't Support Current Global Warming Theories
We've known that for a long time, but it's taking awhile to get the message to the most ardent adherents of the global warming religion:

Tens of billions of dollars have been spent in futile efforts to prove that added CO2 caused Global Warming while an unpaid engineer has discovered what really caused the temperature run-up in the 20th century.
All of the average global temperatures for the entire 20th century and on into the 21st century are readily calculated with no consideration whatsoever needed of changes to the level of atmospheric carbon dioxide or any other greenhouse gas.
Data sources, a graph that overlays the measured and calculated temperatures from 1880 to 2008 and a detailed description of the method are in a new paper at http://climaterealists.com/index.php?tid=145&linkbox=true .
This research shows that there is no significant Anthropogenic Global Warming (AGW) (and therefore no human caused climate change) from added atmospheric carbon dioxide or any other added greenhouse gas.
