GLOBAL WARMING

A huge level climate change in the current time attracts the people’s attention very easily. Every one of us is feeling very clearly from the short-term changes in the seasonal patterns of temperature, drought, rainfall without season, changing weather patterns, etc. to the long-term changes affecting the entire earth. Climate is a long-term weather trend affecting human lives positively or negatively. Climate change is the long term variations in the weather patterns.

Climate itself adjusts time to time however going at wrong path since many years because of regular loss of huge ice sheets. Earlier the earth atmosphere was covered with ice sheets which were able to make the earth atmosphere cool by preventing earth from heat and sending back extra heat out of the space from the earth.

Climate has changed from cooler to warmer over the last two million years in the cyclical manner. Sun is the ultimate source of heat energy which fuelling the weather systems after reaching to the earth. Earlier the harsh and extended bitter cold season was called as the little ice age which was due to the huge level variations in the solar activity. It is found that the positive human activities may play major roles in shaping earth’s climate. Such a huge variations in the climate may lead to the danger of the human lives. Earlier it was believed that shifts in the climate pattern from ice age to warmer periods was because of time however later it was imagined that it is due to regular melting of ice sheets of more than a kilometer in thickness. Our climate is getting warm rapidly by the rate of approximately 8°C over the course of 10 years.

A huge industrial revolution in the modern time has largely impacted the global cli...

...onsumption of fossil fuel has increased dramatically. The world now burns at least five billion tons of fossil fuel each year. As this carbon dioxide from burning fossil fuels enters the atmosphere, some of it is taken up by photosynthesizing plants, and the oceans absorb some.

But because we are burning so much fossil fuel at such a rapid rate, we are putting carbon dioxide into the atmosphere much faster than these natural processes are taking it out. There is no longer a balance between the amount of carbon dioxide being added to the air and the amount of carbon dioxide being removed. As a result, the concentration of carbon dioxide in the air is steadily increasing.

In conclusion, if we make small changes now in the way we live, we can avoid huge changes in the future. Scientists, governments and individuals must work together to overcome this threat.
