Read here, here, and here. From the bowels of Climategate, we've learned of the corruption and treachery of a group of high level climate scientists. We also learned of their insufferable arrogance, which may be the ultimate climate forcing that has led to investigations for some. Often this arrogance is presented in terms of "consensus," when in reality there is no such thing in climate science. One of the supposed areas of "consensus" is in the field of glaciers - "there all melting and will soon disappear"! As the above linked articles indicate, the science of glaciers is in its infancy and it is dynamic. New discoveries are being made all the time, which keeps upsetting the current thinking.
Despite the new science that indicates glaciers aren't as in dire danger as hyped, the IPCC continues to insist that their old science is correct. It's not only the individual climate scientist that is arrogant.
