And now for a little science

Rico says, as much as he hates winter, global warming just isn't keeping up with the problem. These two charts perfectly illustrate how delusional we are about what can happen with the weather; note that, after four hundred years of warming during the Medieval Period, we had four hundred years of the Little Ice Age. Yes, things have been getting warmer since then (and we have a very different atmospheric engine these days, it's true), but that's probably what they were saying in 1200AD... (And let's remember that London used to have Frost Fairs when the Thames froze over, as it did in 1063, 1076, 1434, 1515, 1564, 1683, and 1739...)
