BIO Note: Physicist Walter Cunningham, an award-winning NASA Apollo 7 Astronaut, was the recipient of the NASA Exceptional Service Medal and Navy Astronaut Wings, the 1969 Haley Astronautics Award and named to Named to the International Space Hall of Fame. Cunningham is a member of the American Geophysical Union and fellow of the American Astronautical Society. He also worked as a scientist for the RAND Corporation prior to joining NASA. While with RAND, he worked on classified defense studies and problems of the earth’s magnetosphere. He has accumulated more than 4,500 hours of flying time, including more than 3,400 in jet aircraft and 263 hours in space.

It doesn’t help that NASA scientist James Hansen was one of the early alarmists claiming humans caused global warming. Hansen is a political activist who spreads fear even when NASA’s own data contradict him. […] NASA should be at the forefront in the collection of scientific evidence and debunking the current hysteria over human-caused, or Anthropogenic Global Warming (AGW). Unfortunately, it is becoming just another agency caught up in the politics of global warming, or worse, politicized science. Advocacy is replacing objective evaluation of data, while scientific data is being ignored in favor of emotions and politics. […] I do see hopeful signs that some true believers are beginning to harbor doubts about AGW. Let’s hope that NASA can focus the global warming discussion back on scientific evidence before we perpetrate an economic disaster on ourselves.
[…] The fearmongers of global warming base their case on the correlation between CO2 and global temperature, even though we cannot be sure which is cause and which is effect. Historically, temperature increases have preceded high CO2 levels, and there have been periods when atmospheric CO2 levels were as much as 16 times what they are now, periods characterized not by warming but by glaciation. You might have to go back half a million years to match our current level of atmospheric CO2, but you only have to go back to the Medieval Warming Period, from the 10th to the 14th Century, to find an intense global warming episode, followed immediately by the drastic cooling of the Little Ice Age. Neither of these events were caused by variations in CO2 levels. Even though CO2 is a relatively minor constituent of “greenhouse gases,” alarmists have made it the whipping boy for global warming (probably because they know how fruitless it would be to propose controlling other principal constituents, H2O, CH4, and N2O). Since human activity does contribute a tiny portion of atmospheric CO2, they blame us for global warming.
[…] The reality is that atmospheric CO2 has a minimal impact on greenhouse gases and world temperature. Water vapor is responsible for 95 percent of the greenhouse effect. CO2 contributes just 3.6 percent, with human activity responsible for only 3.2 percent of that. That is why some studies claim CO2 levels are largely irrelevant to global warming. Without the greenhouse effect to keep our world warm, the planet would have an average temperature of minus 18 degrees Celsius. Because we do have it, the temperature is a comfortable plus 15 degrees Celsius. Based on the seasonal and geographic distribution of any projected warming, a good case can be made that a warmer average temperature would be even more beneficial for humans.
