What about the sun
Worrying about issues that might affect us, our children, grand children or great great grand children due to climate changes, global warming or what ever is only short term. The real issue revolves around what happens when the sun runs out of fuel and becomes a red giant. That's too far down the track for any one to worry about. Tell that to those who might still be here then. The moral of this story is at some point we will be returned to the periodic table from whence we came and all the bickering over subjects like this will become irrelevant.

There are some effects that it is too late to reverse, but what we do over the next several decades is extremely important to what kind of world we leave to our children and grandchildren. The mean temperature of the Earth has already risen by about 1 F, and even if we were to stop emitting carbon as soon as possible, it will continue to rise to 2.5 F above normal by the end of the century. But if world emissions continue to grow at current rates, the rise will be 10 F. Sea level rose by about 7 inches in the 20th century, and will rise another 7 to 22 inches, depending on what we do. These are big differences.
These model predictions are so well accepted among the scientific community that NASA summarizes them on their website: http://climate.nasa.gov/effects/ Although, the sea level rise estimates keep getting revised upwards as mechanisms for self-accelerating effects are incorporated into the models.
