The Ice Age is already here but is having some trouble kicking in. When it does, which could be right now, it could snap over in very short order.
You look at this data, and you see what the past patterns were, repeating over and over.
The TV show was right, this pattern will likely repeat again. And if we are inducing a warming trend at all, it is probably not a bad thing at all.
Always remember to ignore the Younger Dyrass period. The greater part of the meltdown had already happened when a disaster came along, broke up and precipitously melted a large but otherwise residual ice sheet in Canada, and fostered yet another serious freeze in Europe and North America (through a variety of mechanisms).
So what is it that's holding the cold back?
Most likely agricultural practices, particularly irrigation, that warm the lower atmosphere and the soil.
This is only going to last so long and then we are going to be so far into the ice cycle that it'll just drop straight down on our heads in the Middle of the Super Bowl.
What is “very short order” in geologic terms?
