Your Wiki graph shows that at about 120,000 years ago, the temperature of the Earth was about 4 degrees more than now.
How did that happen with so few humans in existence then?
That graph suggests that we still have a bit of a way to go with some more natural warming before we hit the next ice age and head down again as we have many times before.
How did all of those variations in the ice core come about over 800,000 years?
There are 20 degree changes from the top to the bottom and then back again without any human intervention and they come in quite regular cycles.
So much for a stable earth climate that doesnt vary one bit until humans started burning coal recently!
