Global Warming Causes the Snow Storms on the East Coast

The global warming has become one of the most serious environmental problems facing humanity, which is mainly caused by the increasing levels of carbon dioxide and other greenhouse gases emitted mostly from fossil-fuel combustion.These greenhouse gases absorb thermal infrared light and eventually result in rising temperature. An increase in average air temperature can cause extreme weather becoming more common. Recently, the snow storm on the east coast was thought due to global warming.
Physics professor Michio Kaku explained that as North Pole being gradually heat up, excess heat generated by all the warm water destabilizes the gigantic bucket of cold air, which could cause the jet stream and the polar vortex becoming unstable and result in the cold air spilling out over the United States. The instabilities caused by the jet stream could also be connected to a series of wacky weathers such as frozen of Niagra Falls, floods in England, warmth in Latin America, and drought in California, Kaku said.

Furthermore as the temperature rises, the melting of polar icecaps and sea ice will cause more instability of cold air, resulting in more extreme weathers. Even though there is a disagreement over global warming causing such winter storms, it is almost undoubted that the average global temperature is gradually increasing and it can cause extreme and violent weather events becoming more frequent. The rising temperature in North Pole seems to be irreversible at a certain point, but there are still many things we can do such as reducing greenhouse gas emission and replacing carbon based energy with other energy sources in order to slow down the global warming.
