I've been hearing data from everywhere across the spectrum, from Extinction-level Crisis to Fake Story. What is the truth? If it's true, how bad is it? What's the worst case scenario?

Any geologist can tell you the natural outcome of every know case of global warming has been ice ages. we have had numerous ice ages with out benefit of help from man. so is global air polution sufficient to help push the natural forces of weather to precipitate the next ice age? that is the question that is debated and if we have no power to stop hurricanes, what is our ability to cancel out global warming? mankind has indeed survived numerous ice ages and so this is not an extinction level event, the greatest asset of homo sapiens is adaptability to environment. However this won't happen next year, this is not the 2012 apocolypse. More like 100 generations to come will be the extreme weather condition.

Human activity is causing global warming.
The data over the past ten or twenty years shows the fastest rise in global temperatures the world has ever seen.
Some results:
1) Millions of acres of farmland will become barren due to drought or flood. This results in famine and social unrest.
2) Thousands of square miles of land that is currently inhabited or used for farming or industry will be inundated by the oceans in the next century. Prevent it, say, with dikes, will cost trillions of dollars.
3) Species of plants and animals that can't adapt fast enough to a rapidly changing climate, will die. These extinctions will have several direct causes: increase of insect damage, increase of fungal attacks, inability for the plant/animal to deal with higher/lower temperature and more/less water.
In other words: within thirty years we will see massive social upheaval due to starvation and loss of land, food prices will skyrocket as crop yields plummet, millions of square miles of land will be denuded of trees. Some rivers will disappear, other areas will be subject to annual flooding.
