That, and one billion years from now the Earth will be toasted out of it by the expanding Sun.
I don't think the cause matters at this stage. The Earth is well on its way to heating up and starting a new Ice Age cycle. I did see a video on micro-algae lamps that would absorb the CO2 on a large enough scale but it is probably too little too late.
Besides I think all global warming has done is put off the next Ice Age for a little bit. It was always going to come anyway.
It would be interesting to see if our species survives it or not. The last time the human population was reduced to pockets of handfuls of people and we just about survived. It is also intriguing to note that the Neanderthals were wiped out in the last Ice Age, 28,000 years ago (it may have had something to do with the energy needed for their larger brains).
We are much more technological advanced now. However, on the flip side our population is perhaps a million or more times larger.
