The earth is tough. To say it is "to far gone" is simply mistaken, and you state that "... I heard that we were giving up on this earth and trying to terraform mars." yet I see no citation for this evidence. While I do agree that it is to late to save the vast majority of the ice caps, it is not impossible to stop or at least slow down the melting to an acceptible level. Regarding your cries of mass extinction, yes, the seas will rise as will the temperature. I am not a specialist on weather patterns, but I feel that if the heat rises so does the rate of evaporation, which in turn creates clouds and rain which would help the temperature level off, at least by a little. I agree Yellowstone will eventually erupt, however I do believe that if the situation becomes dire enough, people would find a way to release the pressure gradually to at least reduce the wide-spread effects of the eruption. As for the ice age, that would be one of the least of humanities worries about a super-volcano eruption. Other greater concerns would be the massive amounts of toxic gas released into the atmosphere. Furthermore, regarding your hopes of colonization of mars, that would be impossible at the current time, due to the massive intra-country conficts going on. Also as a final thought, you speak as if the earth would die, it is a rock in space, it will be fine. It is us who would die.
