Global Warming

“The moderate increase in global temperature, too, should benefit civilization.  This is not just unfounded speculation.  The effects of the climate fluctuations of the past millennium support the notion that warm periods are preferable for civilization.”  Guillermo Gonzalez and Jay W. Richards, The Privileged Planet, p. 360

“There is a huge (and rapidly growing) volume of published material demonstration the many benefits to the biosphere and to civilization of elevated carbon dioxide levels.”  Ibid.

“There is much historical anecdotal evidence that the Little Ice Age was much harsher on European peoples than the Medieval Warm Period.”  Ibid.

“There is also increasing evidence that the Medieval Warm Period and Little Ice Age were global phenomena.  If the many predicted catastrophes resulting from warmer temperatures (such as the shutdown of the Atlantic circulation or the sudden release of methane from the ocean floor) did not already occur during the Medieval Warm Period (or during the even warmer ‘Holocene maximum,’ about five thousand years ago), then they are not likely to occur in the coming centuries either.”  Ibid.

 “Some prominent voices at NASA are fed up with the agency’s activist stance toward climate change.  The following letter asking the agency to move away from climate models and to limit its stance to what can be empirically proven, was sent by 49 former NASA scientists and astronauts.

“The letter criticizes the Goddard Institute for Space Studies especially, where director Jim Hansen and climatologist Gavin Schmidt have been outspoken advocates for action.

“The group, which includes seven Apollo astronauts and two former directs of NASA’s Johnson Space Center in Houston, are dismayed over the failure of NASA, and specifically the Goddard Institute for Space Studies (GISS), to make an objective assessment of all available scientific date on climate change.   They charge that NASA is relying too heavily on complex climate models that have proven scientifically inadequate in predicting climate only one or two decades in advance.

H. Leighton Steward, chairman of the non-profit Plants Need CO2, noted that many of the former NASA scientists harbored doubts about the significance of the CO2-climate change theory and have concerns over NASA’s advocacy on the issue.  While making presentations in late 2011 to many of the signatories of the letter, Steward realized that the NASA scientists should make their concerns known to SASA and the GISS.

“’These American heroes—the astronauts that took to space and the scientists and engineers that put them there—are simply stating their concern over NASA’s extreme advocacy for an unproven theory,’ said Leighton Steward. ‘There’s a concern that if it turns out  that CO2 is not a major cause of climate change, NASA will have put the reputation of NASA, NASA’s current and former employees, and even the very reputation of science itself at risk of public ridicule and distrust.’  Greg Poliowitz, Business Insider, April 11, 2012
