In the modern age of global warming where everybody is talking about weather and climate change however nobody is thinking about solving it. According to the research, it has been found that average earth temperature has been raised by 0.2 degree celsius in every decade. Temperature and global warming, both are affecting each other. Global warming has become an imminent threat to the existence of life on the earth. Many green house gases absorbs high amount of solar energy and heat on daily basis as well as warming the earth surface. Earlier, most of absorbed heat was radiated back to the space by the earth in order to maintain natural process and balance of heat and energy in the environment however this process has been stopped.
Nowadays, once heat and energy absorbed on the earth by the green house gases do not go back to the space and remains on the earth. The availability of high level of heat on the earth causes many negative effects and disturbs the ecology balance. There are many green house gases available on the earth however carbon dioxide and water vapour have more power to absorb infrared radiations of the earth and block such radiations to go back to the atmosphere. All the absorbed heat gets re-emitted to the earth’s surface and heat up the whole earth’s surface by increasing the temperature is known as green-house effect.
Increasing temperature causes both carbon dioxide and water vapour to get combined which impacts the global climate. This combined effect may increase the temperature by 30 degree Celsius in the surface temperature if the level of CO2 becomes double. The most alarming fact about the ever increasing surface temperature by 1 degree Celsius may hugely affect crop production all over the world due to warming of surface layer.
