Hello everyone in this question we will be talking about climate change and its causes.
00:09
So there are certain basic cause for the climate change.
00:14
The number one being the greenhouse gases that causes the global warming.
00:21
So basically all the incoming solar radiation that is less than 0 .3 micro.
00:30
Meter micrometer is absorbed by oxygen and ozone and this absorption takes place in the stratosphere and most of the radiation passes through atmosphere without be absorbed so most absorbed by the land and oceans so the absorbed energy is re -radiated upward from the earth's surface in form of long wave infrared radiation that is more than 4 micrometer which is absorbed by water co2 di -nitrogen oxide and ch4 in the atmosphere the radiatively active gases that absorb the radiatively active gases that absorb the wavelengths longer than the 4 micrometer are called the greenhouse gases.
01:41
The absorption of energy by greenhouse gases heats the atmosphere and radiates energy back to earth.
01:51
The greenhouse gases act as thermal blanket around the earth, raising the earth's temperature.
02:00
That is the greenhouse effect.
02:02
The chemicals like chloroflorocharbons, hydrofluorocarbons, perflorocarbons, sulfurophorobins, sulfur hexafluoride are certain gases that are harmful and the increase in earth's average surface temperature due to the rising level of greenhouse gases is called the global warming...
