Global Climate Change could also be considered a Technological Singularity by itself

I was thinking about this tonight. If you go back 10 to 15,000 years now all the fires and everything humans have cut down and built houses with and all the slash and burn farming techniques and all the factories billowing smoke and all the forges building weapons for thousands of years now helped create the Global Climate Changes we are presently experiencing. So, if 500 to 1000 years from now humans go extinct on earth or have to move to another planet to survive then Global Climate Change is also a Technological Singularity in and of itself caused by humans and their advancing technology starting with fire 10,000 to 15,000 years ago now.
