REDUCE THE CLIMATE CHANGE EFFECTS, BY FOCUSING NON-CO2 GREEN HOUSE GASES


As we all are aware of it that, the climatic change and its adverse effects are mainly caused by green house gases. Also various research shows clear perspective that of the various green house gases carbon dioxide seems to be the most hazardous. There had been lot of research to reduce carbon dioxide in the atmosphere. It’s hard to say that we could not find the most apt and best way to get rid of excess carbon dioxide from the atmosphere.  It doesn't mean that we cannot get rid of CO2, but it will need some time for the research to be carried out. As the time span is less, more we wait more adverse effects we would have to face. In order to minimize the adverse effects of climatic change researchers suggested changing the focus. They pointed that as we are on the hot spot and we have to take action to the earliest so instead of just concentrating on CO2.  We can concentrate on other green house gases and acute the effects on climatic change. From the research done by NOAA scientists the graph below shows that there are four ways how the effect of climatic change would go. First is if we go on emitting the way we are emitting, then the direct radiative forcing which is now 2.75W/m2 will reach 4W/m2 in around 40 years. Second if we cut 80% of non CO2 greenhouse gases emission the same direct radiative forcing of 4W/m2 would be achieved around 2100 nearly 90 years from now. Third is if we cut 80% CO2 emission the maximum direct radiative forcing will be around 3.2W/m2 till 2100, which is far better if we get. Finally if we are able to cut 80% of complete greenhouse gases we can even reduce the maximum direct radiative forcing below the present value up to 2.55W/m2. This way we can have some solution over the climatic change issue.



We all have to come forward and contribute our best to save our earth and natural resources.
