(by Michael Bastasch, The Daily Caller) – A group of 15 scientists and meteorologists have put forward a scathing rebuttal to the Obama administration’s recent climate report which said the U.S. is already being harmed by global warming.

Scientists skeptical that mankind is causing the Earth’s climate to change say that such claims are based on false theories and flawed models. The White House report is a “masterpiece of marketing” that is trying to scare people into action, scientists said.

“As independent scientists, we know that apparent evidence of ‘Climate Change,’ however scary, is not proof of anything,” wrote the 15 scientists and meteorologists,including Dr. Don Easterbrook of Western Washington University and Dr. George Wolff, who formerly chaired the Environmental Protection Agency’s Clean Air Scientific Advisory Committee.

“Science derives its objectivity from robust logic and honest evidence repeatedly tested by all knowledgeable scientists, not just those paid to support the administration’s version of ‘Global Warming,’ ‘Climate Change,’ ‘Climate Disruption,’ or whatever their marketing specialists call it today,” they continued.

The White House’s “National Climate Assessment” (NCA), released last week, claimed that the U.S. was already being affected by global warming though warmer temperatures and increasing extreme weather events.

But the 15 skeptical scientists said the White House is trying to lay the blame for global warming at the feet of the fossil fuels industry when there is little evidence to back up that claim. The Earth’s climate is very cyclical and has gone through many changes in the past, the scientists said, without humans emitting carbon dioxide.

“This NCA (White House’s “National Climate Assessment”) is so grossly flawed it should play no role in U.S. Energy Policy Analyses and CO2 regulatory processes,” the skeptics wrote. “As this rebuttal makes clear, the NCA provides no scientific basis whatsoever for regulating CO2 emissions.”

“We are asked to believe that humans are drastically changing the earth’s climate by burning fossil fuels,” they added. “The problem with their theory is very simple: It is NOT true.”

The NCA says the U.S. average temperature has risen between 1.3 degrees Fahrenheit to 1.9 degrees Fahrenheit since 1895, which is causing more extreme weather, like hurricanes and droughts, and harming fragile ecosystems around the country.

The NCA also warns that the U.S. average temperature could rise 4 degrees Fahrenheit in the coming decades if nothing is done to limit carbon dioxide emissions. The report suggests a slew of regulatory solutions from cap-and-trade to green energy subsidies to mitigate [ease] global warming.

“’Global Warming’ has not been global and has not set regional records where warming has occurred,” the skeptical scientists rebutted. “For example, over the last fifty years, while the Arctic has warmed, the tropical oceans had a flat trend and the Antarctic cooled slightly.”

“The most significant warming during this period occurred in the Northern Hemisphere, north of the tropics but that ceased over the last 15 years or more,” they wrote, adding that “over the last 130 years the decade of the 1930s still has the most U.S. State High Temperatures records.”

“And, over the past 50 years, there were more new State Record Lows set than Record Highs,” they wrote. “In fact, roughly 70 percent of the current State Record Highs were set prior to 1940.”

President Obama touted the NCA’s findings late last week when announcing his plan to promote more solar power use through executive orders. [A presidential executive order  is a directive issued to federal agencies, department heads, or other federal employees by the President under his statutory or constitutional powers.]

“So unfortunately, inside of Washington we’ve still got some climate deniers who shout loud, but they’re wasting everybody’s time on a settled debate,” Obama said, doubling down on remarks made during his State of the Union Address this year by adding that, “Climate change is a fact.”

“Here in California, you’ve seen these effects firsthand,” Obama told the audience at a Mountain View Wal-Mart. “You know what’s happening. And increasingly, more and more Americans do — including, by the way, many Republicans outside of Washington.”

The Obama administration and environmentalists have tried to make it seem like there are virtually no dissenting voices among scientists that mankind is causing the Earth to warm rapidly and towards a catastrophic end. But not all scientists are in lock-step with the White House on climate science.

“By ignoring and even denouncing growing criticism, they have lost the benefit of crucial scientific debates which are critical to keeping their analyses honest and objective,” the 15 skeptical scientists wrote. “In fact… they are even disregarding their usual allies, the U.N. IPCC and U.S. National Academy of Sciences, both of whom have been dialing back apocalyptic claims [that there will be catastrophic destruction on earth], not [increasing] them due at least in part to such critical feedback.”
