In any case, we're all screwed... If the world doesn't end, an asteroid is going to wipe us out, if that misses us, and we all know the goa'uld are not the best at wiping out us earthlings, then I'm sure some other doom shall befall us... Continuous rising surface temperatures, more holes in the ozone layer, nuclear war???
There is no way out.. We're all going to die here on earth...
