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.
Watch this video to see how professor Michio Kaku explains it.
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.
