Well what many haven't actually considered is how all pollution aside the extra CO2 is speeding up our natural warming process which will in the end speed up our return to a cooling process and may even exacerbate it. Runaway global warming can accelerate the later cooling pattern that the earth will naturally go through and may even make it worse.
Like the movie The Day After Tomorrow - it is highly exaggerated and will not happen that way, but the warming will cause our storms to get stronger. We've had the most active and most powerful hurricanes to date after the year 2000. It is also known that our polar ice melting has accelerated dramatically beginning around 1994. Sea level rise however modest is about to destroy the city of Venice, Italy. Paintings from the year 1700 or so have shown the sea level was about 2-3 feet lower then. Many stairways in these buildings along their canals are underwater now. Recently there was a project undergone to raise the level of their sidewalks by 4 and a half feet to compensate, and they even are contemplating building offshore retractable walls to protect the city.
The last more important point I want to make is the desalination of the ocean when it reaches a critical point will cause a slowing down of the ocean currents which will cause some areas that are normally mild or temperate to have a colder climate. While the earth as a whole heats up, some areas will suffer from much colder temperatures. Some normally wet areas will have droughts. Others not accustomed to large amounts of rain will also in turn become more wet. The global climate will shift a bit which will cause us to have to adapt and take steps to protect the fragile ecosystems. It is not impossible but requires much preventative care by us humans to balance out our carelessness from times past.
