Climate change is a major concern due to global warming and lots of countries are giving aid towards it. Lets say here in United States we are always looking to control the pollution which is a major cause for global warming. We are also in search for better ways to avoid global warming.
While there is little doubt that man-made climate change is occurring, there is considerable doubt about what exactly the impact of a warmer climate will be on humanity. If there are relatively modest changes only, it makes no sense to force developed nations, meaning e taxpayers of those nations, to provide any payment to developing nations.
