John Nielson-Gammon, a climate scientist at Texas A&M, and Robert G. Brown, a physicist at Duke, have a discussion prompted by RGB's comment at WUWT in which he outlines all the uncertainties in current consensus climate science. JNG is in the process of posting their exchange in 6 parts. Today's is #3.
Read it all. My impression -- both recognize the vastness of our ignorance in understanding climate. Brown makes the case that there is no possible way that we can even begin to claim any understanding of the supposed impact of marginal increases in CO2. The climate scientist, however, seems very unwilling to confess that his field is too much in its infancy to draw any conclusions. Mencken's observation seems apt -- " It is difficult to get a man to understand something when his salary depends on his not understanding it." Or his self-esteem, etc.
