The shutting down of the current would also mean that warm water in the middle latitudes would get even warmer, potentially giving rise to more tropical storms and hurricanes.
The Intergovernmental Panel on Climate Change (IPCC) has organized many of the risks of climate change into five "reasons for concern." [1] [2] The reasons for concern show that these risks increase with increases in the Earth's global mean temperature (i.e., global warming).
The dominant cause of the warming since the 1950s is human activities. This scientific finding is based on a large and persuasive body of research. The observed warming will be irreversible for many years into the future, and even larger temperature increases will occur as greenhouse gases continue to accumulate in the atmosphere.
The controversies are, by now, mostly political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. [2] Public debates that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases (climate sensitivity).
