Go back far enough and the earth's surface temperature was in the 1000s of degrees, shortly after it was formed, but that is not the point. There is now overwhelming evidence that the rapid heating of the planet since the industrial revolution is due to human activity that has increased CO2 levels in the atmosphere. It's not so much how hot it is getting, but how fast.
