Spencer was formerly a senior scientist for climate studies at NASA's Marshall Space Flight Center where he received NASA's Exceptional Scientific Achievement Medal, and currently principal research scientist at the University of Alabama in Huntsville.
Excerpts:
As a climate scientist, I would like to see some answers to a few basic global warming science questions which I’m sure the U.N.’s Ministry of Global Warming Truth (also known as the Intergovernmental Panel on Climate Change, IPCC) can handle. After all, since they are 90% confident that recent global warming is manmade, they surely must have already addressed these issues:(Via Marc Morano)
...
The fact that we don’t have a good enough understanding (or observations) of cloud changes, or precipitation efficiency changes, on decadal time scales to document such potential mechanisms seems like pretty weak justification for blaming all of our recent warming on mankind. And if you say, "well, the IPCC doesn’t claim that ALL of the warming is manmade…", then tell me: About what percentage of the warming IS natural, and how did you come up with that quantitative estimate?
I fear that the sloppy science that too many climate researchers have lapsed into could, in the end, hurt our scientific discipline beyond repair. The very high level of certainty (90%) claimed by the IPCC for their manmade explanation for warming can not be justified based upon the scientific evidence, and is little more than an expression of their faith that they understand the causes of climate variability – which they clearly don’t.
For those scientists who value their scientific reputations, I would advise that they distance themselves from politically-motivated claims of a "scientific consensus" on the causes of global warming -- before it is too late. Don’t let five Norwegians on the Nobel Prize committee be the arbiters of what is good science.
