    That’s pretty neat. Wondering about all this rain, checked the NOAA website and found the average precipitation in the Northeast is 41″/yr. From 1895 to 1970 precip exceeded 46″ 3 times. Since 1970 that happened 13 times and 5 of those since 2000. 2011 broke the record by 2 inches with nearly 55 inches of rain, remember Irene?

    A cool connected fact is that the weight of those ice sheets pushed the top of North America down and it is still slowly rebounding. Should allow a few climate deniers in the far north east to ignore rising sea levels a little longer.

    During the biggest of the ice ages, (the cryogenian, for example) the glaciers made it to about the equator. A glacier period like that would make an awesome movie, but not a very likely one, since we create our own carbon dioxide these days. It only takes about 10 million tons of carbon dioxide (per day) to stop an ice age, and we are dumping about eight times that much into the air.

    During much of the last 542 million years, (ever since “land plants”,) the Earth was relatively ice-free, even at the poles. Regardless of what we think about the Earth’s orbit, we are now headed that way again.

    The problem is that we have grown used to the current temperature, and designed our diets (and cities) accordingly. For anyone who has grown fond of their current diet (and cities) now might be a good time to think about what we are going to do with that extra 70 million tons of carbon dioxide per day.
