It's worth noting that in five million years time the Earth's orbit will have increased in size which will have effectively moved us further away from the sun, although the sun will by then be slightly hotter, so it rather cancels out in the end. Either way it is my sincere hope that by such a time we will have left Earth and headed off to the stars.
What I'm trying to work out though is where all this presumed 'increase in the Earth's temperature or rising sea levels or higher doses of UV rays' is going to be coming from and which we apparently need to evolve a resistance too?
You see I am not actually aware that global temperatures are going up, indeed for the last ten years at least they have been consistently falling, I also know of no evidence to support the idea that sea levels are or ever will rise by an appreciable amount nor have I heard anything to suggest that UV levels are on the increase
Anyone care to elaborate on these points?
