I didn't say that. Obviously we have survived and no one has suggested that the Earth might not survive (whatever the fuck that's supposed to mean). I believe this graph is relatively accurate. This is plotted against the global temp in the year 2000. We are currently up a little more than 0.4C since 2000, so this graph indicates that every glacial peak in at least the last 400,000 years has exceeded current temps. Although they look sudden and brief here, those peaks were hit and receded at a pace at least 7-10 times as slowly as temperatures are changing now. As this forum has heard on numerous occasions (but apparently failed to learn) it is not the absolute temperature but the rate of change that matters for life on our shiny little orb.So you're saying that it got extremely hot 100,000 years ago and the earth & mankind survived?
