Physical evidence indicates that when the last ice age started, the British Isles went from a temperate climate to being completely covered with glaciers hundreds of feet thick in just 20 years.

Although I do agree that rapid climate change is possible, contemplate that claim for a moment. Let's make this minimalist and say that hundreds of feet = 200 feet. That means that 10 feet of ice needs to be created each year.

Snow is fluffy stuff. It takes about 10 inches of wet snow to make one inch of rain equivalent, and we'll be generous and say that five inches of snow would compact to an inch of glacial ice. So to accumulate twenty feet of ice per year, that means we would need 100 feet of snow. That's 1200 inches a year - or 240 inches of rain equivalent in the winter. And that doesn't even compensate for seasonal melting.

Yes, I see.

But them damned glaciers sneak in from the north, sliding off the mountains. One day, open prairie. The next, Phloomf! 2 miles thick sheet of ice.

And mammoths crappin' all over the place.

We got 58 inches in 24 hrs in 1986.
