Politicians pushing climate-change legislation such as cap and trade are more interested in grabbing power rather than paying attention to the complete scientific record, Dr. Roy Spencer, a respected former NASA climate scientist, tells Newsmax.TV.
Spencer currently serves as a principal research scientist at the University of Alabama at Huntsville and leads the advanced science team monitoring the Advanced Microwave Scanning Radiometer on NASA’s Aqua satellite, which monitors global climate fluctuations.
“The legislation train left the station over 20 years ago, and it’s going to be very difficult to stop,” Spencer says. “I think there are politicians who really do not care about the science, but are looking to expand government and gain control over our energies.”
Former Vice President Al Gore, who has made millions through his company that buys carbon credits in exchange for planting trees to absorb the carbon, stands chief among them.

“You can’t do that for all the carbon that’s emitted by humanity; it just doesn’t work,” Spencer says. “It’s like he’s trying to convince everyone of the disease we have, and he’s also selling the cure for the disease.”
He also has authored a new book, “The Great Global Warming Blunder: How Mother Nature Fooled the World’s Top Climate Scientists, ” which examines research flaws in theories supporting man-made global warming.
Climate change legislation, such as that being considered by Senate Democrats, intends to reduce carbon-dioxide emissions due using stiff taxation in an effort to reduce alleged global warming, but Spencer says the bill rests on flimsy science.
He says carbon dioxide emissions caused by human activity have a very small impact on overall global climate. Instead, he says carbon dioxide is essential for life because plants use it for photosynthesis, which makes it essential for the rest of the food chain including humans.
“Our latest modeling and information, and satellite data suggests that the clouds are going to act in such a way to reduce the little bit of CO2 warming even more,” Spencer tells Newsmax.TV.
Spencer draws an analogy between global climate fluctuations and what happens when people roll down their car windows to let heat escape on a hot summer day. The prevailing view suggests the planet’s climate system keeps the Earth’s windows rolled up trapping heat and increasing global temperatures, but Spencer says evidence shows otherwise.
He reached his conclusion that CO2 emissions have little impact on overall climate change after reviewing satellite data over the past decade showing “clouds act in such a way as to roll down the window.”
“Basically, what people have done in this area ̶ previous researchers ̶ is they have mixed up cause and effect,” Spencer says. “They have examined cause variations, and they have just misinterpreted cause and effect.”
Newsmax.TV asked Spencer why Gore’s climate guru, NASA scientist James Hanson, continues to take the opposite view.
He says Hanson uses prior ice ages as his benchmark and assumes man-made carbon dioxide emissions upsets the equilibrium between the heat the Earth receives from the sun and what it sends back into space, greatly increasing global temperatures.
“I think we really don’t have a clue why there were ice ages and the interglacials,” He says. “He assumes he knows how nature is working, and I think he’s confusing cause and effect. And that’s also true of a lot of the scientists in this field.
“If you don’t get cause and effect right, you can be totally wrong about the way the climate system responds to forces, and think that’s what all this comes down to.”
Spencer notes in his book that efforts to say a scientific consensus exists on man-made global warming is not science.
Asked by Newsmax.TV why supporters of the man-made global warming theory say a consensus exists, Spencer says it comes down to politics. Unlike people such as Sen. James Inhofe and Weather Channel founder John Coleman, Spencer does not believe man-made global warming is a hoax because he believes in the sincerity of his scientific peers who believe in it.
“If you notice, it is not the scientists who are saying we are sure of the science now; it’s politicians who have taken what a few of the scientists feel what they believe and exaggerated even more in terms of certainty,” he says. “Science is never settled, and in climate science there is so much we do not understand; this is a very young discipline.
“We understand how the climate system works on average year after year; what we don’t understand is how the climate system responds to a little poke in the side such as adding CO2 to the atmosphere, or we don’t know how natural climate change works.”
Spencer says contemporary climate scientists have convinced themselves natural climate change does not exist, and he attributes the climatic changes that have been observed in recent decades to natural fluctuations in the Earth’s climate system.
“It can cause its own climate change just by changing circulation patterns ̶ changing global cloud cover by 1 or 2 percent ̶ it’s all that it takes,” Spencer says. “Once you’ve changed cloud cover by 1 or 2 percent, you’ve got either global warming or global cooling.”
Speaking in response to a question from Newsmax.TV about the validity of the U.N.’s International Government Panel on Climate Change (IPCC), Spencer says the panel was established 20 years ago for purely political purposes, with the aim of reducing carbon dioxide emissions.
The IPCC gathered most of the world’s climate scientists together and succeeded in using the carrot and stick of government research funding to stack the deck in favor of man-made global warming, he says.
“That’s not scientific,” Spencer says. “You should also be looking for alternative hypotheses. What are potential natural methods of climate change? There is virtually no research being done today; out of the billions of dollars we spend on climate research there is virtually none going into possible alternative explanations for climate change for global warming.”
Spencer says IPCC researchers have ignored the 800-pound gorilla in the room he calls “natural climate chaos,” which includes ocean temperature fluctuations in the Pacific such as El Nino and La Nina, and the Pacific Decadal Oscillation. He theorizes the latter had a lot to do with the cooling period between 1940 and the mid-1970s and the warming period that followed up until 10 years ago.
“It is there that Mother Nature is causing climate change, and nobody is studying it,” Spencer says. “If we get that wrong, we can totally misinterpret how sensitive the climate system is to how much CO2 we put in the atmosphere.”
