Shed,
The planet is still recovering from the last glacial maximum that reached its zenith around 20K years ago with the ice retreating from what we know as the US of A approx 12K years ago. Glaciologically speaking, we are still in the last ice age because the poles of our planet still remain covered in ice.
That human presence has had an effect on the planets climate there is no doubt. But to infer as you so vociferiously do that our civilization is the dominant cause is IMO a myopic viewpoint.
IMHO, the sun's varying intensity and our planets active vulcanism throughout Earth's history have and still dominate the world's climate. Before the Pleistocene age, the world was much warmer with much higher CO2 levels.

"The budget should be balanced, the Treasury should be refilled, public debt should be reduced, the arrogance of Obamunism should be tempered and controlled, and the assistance to foreign lands should be curtailed lest the Republic become bankrupt. People must again learn to work, instead of living on public assistance."
. . .Evidently nothing.
