So any small change on earth caused by the sun, would be extreamly noticibale on the sun, because the amount of energy reaching earth is basicly an inverse square over the distance.
no its not. That calculation gives an earth that is cooler than it actually is. The actual temperature of the earth is dependent on incoming radiation modified by a very large number of effect due to conditions on the earth. With the right change in conditions on the Earth, the Earth can cool when the sun gets warmer. The opposite is true also. If it werent true, the earth would not be cooler today than it was 12 million, 40 million, and 70 million years ago.
