Snow and ice . . .

Take a look at this. Most of the entire northern hemisphere is covered by ice and snow. But not Portland.

Must be some slackers aren't doing their part to assure global warming.

Time to start reading up about glaciation, I think. I have read that the earth has been pretty much completely ice free at times, and at other times pretty much covered in permanent ice, and that major glaciation kind of scours the earth clean of the records of previous glaciations. I know that about two thirds of the earth is ocean, where people don't live, and I know that much of the land surface is relatively unpopulated, so that if the activities of people are contributing to climate change, it's probably only on a small fraction of the surface of the earth and consequently is probably only a small percentage of the cause of climate change.

So, are we entering a glacial age? Or leaving one?
