Last year, forty former NASA scientists and astronauts sent a letter to NASA Administration Charles Bolden admonishing him for NASA’s role in advocating a high degree of certainty that man-made CO2 was a major cause of climate change while neglecting empirical evidence that calls the theory into question. The group which includes 7 Apollo astronauts and 2 former directors of NASA’s Johnson Space Center in Houston were upset at NASA’s failure to make objective assessment of all available scientific data, charging that NASA is relying too heavily on complex U.N. models that have already been proven inadequate and wrong.

Dr. Vincent Gray, former U.N. IPCC climate scientists said that “there is currently no evidence that included human based emissions of CO2 or other greenhouse gases have any measurable effect on the climate.” He further stated that in his view as an expert reviewer of UN IPCC reports that the “IPCC claims are based on estimates of “likelihood” that model “projections” are “possibly true” by the authors themselves. . .who are “paid to supply the models and are therefore “compromised by conflict of interests.” He also stated that the “assertion that the earth is warming is also without scientific basis since it is impossible to measure the “average” temperature of the earth’s surface and the “Mean Global Surface Temperature Anomaly Record” was riddled with statistical errors. . .”
The scientists organized “the Right Climate Stuff” research team to re-examine the belief that human-generated C02 and other greenhouse gases were creating a global warming crisis and invited a number of scientists, both for and against the global warming theory to study the issue, stipulating that all presentations had to be backed by scientific data.
An initial progress report from the study reports that:
- The science that predicts the extent of anthropogenic (man-made) global warming is not settled science.
- There is no convincing physical evidence of catastrophic anthropogenic global warming; most of the alarm results from output of invalidated computer models.
- Computer models need to be validated before being used in critical decision-making. “Our manned aerospace backgrounds in dealing with models of complex phenomena have convinced us that this rule must be followed to avoid decisions with serious unintended consequences.”
- Because there is no immediate threat of global warming requiring swift corrective action, scientists have time to study global climate changes and improve prediction accuracy.
- The U.S. government is overreacting to concerns about anthropogenic global warming. More carbon dioxide in the atmosphere would be beneficial for forest and crop growth to support the Earth’s growing population, so control of carbon dioxide emissions is not an obvious best solution to hyped-up concerns regarding anthropogenic global warming.
- A wider range of solution options should be studied for global warming or cooling threats from any credible cause.
“Because we are not predisposed to believe climate change is caused by human greenhouse gas emissions, we are able to look at evidence the [U.N.-backed] Intergovernmental Panel on Climate Change ignores,” explains the group’s website. “Because we do not work for any governments, we are not biased toward the assumption that greater government activity is necessary.”
