There are other things that have affected temperature; mainly that the sun was less hot back then, as I understand it. Lots of volcanic ash and other things can cause cooling, as well. The Earth is on a 41,000 year oscillation cycle of the angle of rotation, which affects the polar ice caps, which in turn ripples a myriad of other affects...
Do you really think that it was that simple that somehow *you* figured it out, and all those dumb scientists somehow missed it?
Carbon dioxide is an heat insulator -- this is shown several times in the video I posted earlier. There would be no life here on Earth without the atmosphere, and without the greenhouse affect. And our atmosphere would not have survived the solar wind without the magnetic fields of Earth's core. It is pretty amazing to have life at all; let alone such a lush and hospitable one.
In fact life itself has created the atmosphere we have.
Cyanobacteria first split water and made oxygen a part of the atmosphere. The atmosphere we have had for the 200,000 years or so of human existence is a finely balanced equilibrium that worked to all life's benefit. For billions of years, plants have been packing carbon away in the Earth's crust, and now we have released a huge proportion of it back into the atmosphere in the blink of an eye.
We are probably past peak oil -- why else would we be contemplating the oil sands in Canada?
We've got the same exact water that we had when Earth was formed. The air is the result of life balancing out. How could adding back all that carbon *not* throw things into a tizzy?
