Global Warming

Our planet is warming from the north to the south pole. For many years global average temperature has been rising and has increased around 1.5 degree Celsius, and the effects of rising temperature are melting glaciers which is increasing sea water level, sea ice shifting precipitation pattern and migration of animals.

People think of global warming and climate change as the same but researchers prefer to use climate change while stating the complex shift of weather affecting our planet. While they refer to global warming as an overall effect on the earth’s surface including weather, oceans, forests etc. The term global warming is used specifically to refer to any warming of near-surface air during the past two centuries that can be detected to anthropogenic causes.Taking into consideration the growing threat predicted by scientists, the Intergovernmental panel on climate change was formed in 1988.

A report published by IPPC in 2018 cleared that human beings and human activities have been responsible for a worldwide overall average temperature increase in a range of 0.8 to 1.2 degree Celsius. It also predicted that global surface temperature would increase between 2 to 4 degree Celsius.This prediction for rise in temperature was based on factors like green house gases emission, Emission of gases like Carbon, Sulphur, Nitrous oxides from automobiles and industries. From all these gases carbon dioxide is most important, both for its causes and green house effect.

Other effects that could occur later in this century if global warming continues-

Water level in the sea is expected to rise between 12 to 30 centimeters or even higher by the end of 21st century.Precipitation will increase all across the world and many regions will experience severe draught, wild fires, drinking water shortage etc. Hurricane and storms will become stronger.Many species would find hard to survive in this atmosphere and will get extinct.
