So I wrote up an article a couple days ago, but this is far better, with way more references to actual papers rather than my fuzzy recollections of my own research for the last 10 years. Please look at the data, and the links, and understand this is something all geologists know. You get to learn that glaciers COME BACK in simple undergrad geology. We suspect mechanisms exist that cause the switch to flip, and eventually flip back, but somehow takes 100K years of Ice and 18K (or less) of not. The suggestion, in the article, that planting rice in China emitted so much methane gas that it extended warming and drying a bit longer, that's pretty interesting. Considering the Himalayan hypothesis for starting the ice ages, I have to wonder if there's some geographic cause for these switches. The suggestion that the gulf stream is responsible, having its heat pump interrupted and thus allowing colder air to hit Europe, that might be true.
Instead of presuming the outcome is "warming" they ought to remember that disrupting weather via high or low pressures are already known to shift weather patterns, and there's extensive data on this in Europe. The El Nino and La Nina pacific oscillations are important as well, known to impact global weather. It isn't very sexy, however.
Its not as sexy and massaging bad models which completely missed the boat, and after 17 years with no warming, and a long cold winter in the Midwest that STILL has ice in Lake Superior, the most since we got weather satellites to see it, well, Warming just looks retarded. And nobody cares about "Change" since its linked to all we've got in our pockets after a certain useless politician wrecked our economy under the same claim. Meh.
Read the article. It is pretty interesting.
