There are many uncertainties in predicting climate change. The IPCC{{w|Intergovernmental Panel on Climate Change}} considers that there is a strong probability of serious climate change caused by human activity - but not a 100% certainty. However, their estimates ''may'' be wrong:
* Climate change may be much less serious than expected, and we may have plenty of time to convert to a [[low carbon economy]] of [[renewable energy]] and [[energy efficiency]]. Or...
* If climate change is worse than expected, and we have only taken minor action, there will be a sea rise, crop failures in some areas causing millions of climate refugees, increased [[natural disasters]], greatly increased uncertainty in [[food production]], and major costs in adaptation.

Both the developed as the developing world will be affected. The developing world is expected to be affected to a greater extent though. Some effects are:* changing weatherpatterns (greater or fewer precipitation on specific areas, the weather is also expected to be much more radical).
