Global "Warming" has been flat for a decade. If the Viking farms in Greenland are not capable of growing wheat and grazing cattle (there not) then we haven't yet reached the medieval warm high that we know existed. Good science requires that you take all data into account, not just that which supports your theory. Every item in the article is a case of cherry picked data being exposed when all the data is in. Cherry picked data is a sure sign that the researcher has a political not a scientific agenda. Money and peer pressure are huge issues with scientist just like everyone else. Global warming is "IN" and money flows to the "IN" research.
