Well TNZ for a very long time. And JLowe is partly correct in that glaciers have been melting for awhile though his 500 year figure is a made up number of the top of his head. It could be longer, it could be shorter, he really doesn't know but it was a nice round number and made it sound like he was authoritative. I looked it up and he is laughably wrong.

But the point is not whether they are melting. Rather it is the increased rate at which they are melting. And the implications for the future.

When there is no water left in the Yangtze River it won't matter how many years ago the glaciers started melting. People with AK47s don't ask nicely when they are thirsty.
