Complex organisms have arisen from the 'natural soup', going through intermediates incremental in complexity. Traits that confer competitive advantage have been naturally selected when they enable species overcome 'hurdles' and have accumulated to produce 'fitter' more complex organims.
Global warming would ultimately present survival challenges for many species on earth (including man) if
it is indeed 'man made' and present human behaviour in relation to climate is not changed. Theoritically, atmospheric temperatures, humidity and wind fundamentals of this planet could change so much as to require new physiological adaptations in some species, maybe humans too. So global warming may ultimately make earth a harsher planet tending towards conditions on others in our solar system, for example Mars.
These harsher conditions should select adaptations that are neccessary to survive. Global warming therefore could be a challenge that results in even more resilient species on earth, the sort that could go on and colonize other planets in our solar system and beyond.
Again I am a creationist, but in light of this thought what should be the attititude toward global warming? A threat or a neccessary evolutionally stimulus.
