Boris,
I appreciate your candidness about science but in the 2nd paragraph…There you go again….”However, the vast majority of evidence points in the direction of AGW”. You still make these statements as if they are gospel. I could make the opposite claim….the vast majority of evidence points away from AGW. Neither one means much.
Below is a statement from Dr Roy Spencer. Am sure you are familiar with Dr Spencer.
Dr. Roy W. Spencer—a principal research scientist for the University of Alabama in Huntsville and the U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer (AMSR-E) on NASA’s Aqua satellite, recently asked these questions:
1) Why are all of the more than 20 IPCC climate models more sensitive in their total cloud feedback than published estimates of cloud feedbacks in the real climate system?
2) Regarding those observational estimates of (somewhat) positive cloud feedbacks: How do you know that the cloud changes that have been observed during temperature changes really are “feedbacks”? In other words, how do you know that the temperature changes caused the cloud changes, rather than the other way around?
3) How do you know that the average global warming trend that has, indeed, been observed since 1970 wasn’t the result of a small, natural change in cloud cover? Doesn’t it seem like (another) coincidence that the Pacific Decadal Oscillation (PDO) just happened to shift to a different mode in 1977, about the time that the warming started?
These questions are a big part of why I have a difficult time believing in the AGW.
