NASA's Muzzle Hustle
Just a bit over a month ago, December 14, we ran a blog piece on a NASA web page that said the sun is primarily responsible for climate change, and that whatever warming is caused by man's contributions to greenhouse gases is swamped by the effects of the sun and other natural variables.
"The Sun is the primary forcing of Earth's climate system... According to scientists' models of Earth's orbit and orientation toward the Sun indicate that our world should be just beginning to enter a new period of cooling -- perhaps the next ice age...Other important forcings of Earth's climate system include such ‘variables' as clouds, airborne particulate matter, and surface brightness. Each of these varying features of Earth's environment has the capacity to exceed the warming influence of greenhouse gases and cause our world to cool."
- Before: "our world should be just beginning to enter a new period of cooling -- perhaps the next ice age."
- After: "the rate of our world's warming accelerated and scientists predict that the globe will continue to warm over the course of the 21st century."
- (a) "NASA headquarters had ordered the public affairs staff to review... lectures, papers, postings on the Goddard Web site and requests for interviews from journalists."
- (b) "That's not the way we operate here at NASA. We promote openness and we speak with the facts."
