Well Earth is getting more distance from sun we have a angle of 1 to 27 degree we are now in 7 degree of distance ... the big problem is the waste of our energy sources that give us enought energy to survive in a glaciar age. We are know 14 thounsand years of warm weather cycle and maybe in a near future 100 thousand years of glaciar age. The big problem in Mars was the internal vulcano activity that disapear and destroyed electro magnetic fields in polo's. At the moment we now that Earth is changing is magnetic fiel from North to South, the big activity that sun show us in 2000 is slowing down, we are near the limit of 14 thousands years of warm weather and 2008 was the coolest year in 50 years timeline. The big problem of CO2 is Venus effect, and that my contribute to an irrersible "hell" in earth. ... but we are parasite and adapt and we go to Mars or Europe in Jupiter and so on ... ;) :P
