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.
