Astronauts and former employees caution NASA on global warming claims

Approximately 50 former astronauts and scientists have sent a letter to NASA regarding claims that manmade carbon emissions are the cause of global warming. In the letter, the experts ask the agency to “refrain from including unproven and unsupported remarks in its future releases and websites on this subject.”

Branded media and politicians frequently claim that the science is “settled” regarding carbon emissions causing Planet Earth to warm. Al Gore, perhaps the most recognizable voice in the government-academia global warming complex, actually declared the science “settled” during testimony before Congress in 2007.

However, concurrent with a mobilization of agreement on Gore’s claims, a counter-movement coalesced. That counter-movement disagrees with the Gore sector on what is causing the planet to warm, and on whether records on warming aren’t a reflection of past cycles on the planet when natural cooling and warming spells occurred.

The letter followed an announcement in early April delivering positive but unexpected news about ice in the Arctic’s Bering Sea. The Register (London), a tech publication, said:

“The US National Snow and Ice Data Center announced last week that ice extent in the Bering for the month of March has now been collated and compared, and is the highest seen since records began.”

A website familiar to those who consider themselves “climate realists”, Climate Depot, splashed The Register’s announcement above the fold in very large type.

One group, The Heartland Institute, holds an annual conference to examine different theories about global warming and climate change. The conference for 2012 will be held in May in Chicago. The Institute said the conference will feature “60 scientists and policy experts speaking at plenary sessions and on three tracks of concurrent panel sessions exploring what real climate science is telling us about the causes and consequences of climate change, and the real consequences of choices being made based on the current perceptions of the state of climate science.”

The astronauts and scientists—among them, the ex-head of the Johnson Space Center— who sent the letter to NASA definitely believe Gore is in error by claiming the science is “settled”:

"We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated, especially when considering thousands of years of empirical data. With hundreds of well-known climate scientists and tens of thousands of other scientists publicly declaring their disbelief in the catastrophic forecasts, coming particularly from the GISS leadership, it is clear that the science is NOT settled.

The unbridled advocacy of CO2 being the major cause of climate change is unbecoming of NASA’s history of making an objective assessment of all available scientific data prior to making decisions or public statements."

Some images at NASA have captions that climate change has occurred on other planets, despite the fact there are no carbon emissions by humans on those bodies.

Ignoring contradictory theories, James Hansen, who heads up NASA’s Goddard Institute for Space Studies in New York City, has called for a global government and a global tax on carbon. Hansen believes power must be removed from the “hands of individual states” and he uses “states” as a reference for nations.

Luboš Motl, a physicist who was an assistant professor at Harvard before returning to his home in the Czech Republic, blogs about physics topics and politics. In a recent post, Motl criticized Hansen and his supporters for politicizing science:

“People around Hansen have stopped interacting with scientists or sensible people in general many years ago. They're not even trying to hide anymore that they have switched from attempts to find valid answers to scientific questions – a challenge in which they have failed miserably – to pure political activism.”

Motl noted that Hansen has also declared global warming to be as important an issue as slavery.

In 2011, Nobel Prize winner Dr. Ivar Giaever refused to renew his membership in the American Physical Society because of the organization’s stance on global warming causes. Giaever said, “The claim (how can you measure the average temperature of the whole earth for a whole year?) is that the temperature has changed from ~288.0 to ~288.8 degree Kelvin in about 150 years, which (if true) means to me is that the temperature has been amazingly stable, and both human health and happiness have definitely improved in this 'warming' period.’”

Current political policy driven by government’s support for manmade warming theories has resulted in costly regulations on energy for both individuals and businesses in the U.S.
