What do you mean wit "out of control"?If you think, it wil be a run away to sky high ttamerpeures, this will not happen. Climate is able to stabilise on a higher temperature, when the changing forces stabilise first.But, if you think about impacts on human civilisation and culture, these effects are already beyond our control. Take hurricane Katrina as example. Although climate change is not really to blame for this, you see, how difficult it is, to prevent such events and how difficult it is to repair the damage. Think about only 1m rise in sea level. This will generate about some hundred million refugees worldwide, not only in Bangladesh, in USA too, not to forget the vast amounts of money to protect the coasts against the sea.That, what scientists say is, if we do not reduce production of carbon dioxide to halv the amount of todays production untill 2050, with start next year, we will get it warmer than 2 centigrade.If we wait to 2015 we have to reduce to 1/10th of todays production. Do we wait longer than 2015, we do not have a chance to to brake at a temperature rise of 2 centigrade.But be aware, already with 2 centigrade rise there will be a rise in sea level of 1-2 m, with huge problems following this.nevertheless, a rise of temperature above 2 centigrade will not be a problem for you as individual. Temperature will level out only higher than 2 degrees, but it is very likely that we have to face a runaway in melting of sea and inland ice of the Arctic and Antarctic and Greenland, and this will mean a rise in sea level of about 70 m.
