Essay on global warming and its impact

The term global warming was first used in its modern sense on 8 August 1975 in a science paper by Wally Broecker in the journal Science called "Are we on the brink of a pronounced global warming?". Broecker's choice of words was new and represented a significant recognition that the climate was warming; previously the phrasing used by scientists was "inadvertent climate modification," because while it was recognized humans could change the climate, no one was sure which direction it was going. The National Academy of Sciences first used global warming in a 1979 paper called the Charney Report, it said: "if carbon dioxide continues to increase, we find no reason to doubt that climate changes will result and no reason to believe that these changes will be negligible." The report made a distinction between referring to surface temperature changes as global warming, while referring to other changes caused by increased CO 2 as climate change.

Further, zombietime seems unable to recognize what is a somewhat speculative discussion about competing factors in determining global temperatures based on the science of the day.; Holdren and Ehrlich mention that temperatures had decreased degrees C 1940-1965 and that a much, much greater decrease of 4 degrees C “would probably be sufficient” to trigger an ice age. They discuss the role of greenhouse gases and do, in fact, overemphasize the role of burning fossil and nuclear fuels in warming temperatures. zombietime somehow interprets this as Holdren and Ehrlich predicting “probable likelihood” of a coming ice age.

Overall of this assignment, I have understood that our earth is "sick". We humans need to "heal" the earth. Global Warming have causes many problem for human but we human who make global warming happens. Many people have died because of disease or disaster. It also affects the economics of the country. However, we need to be reduce the global warming by using less gasoline, recycle and human should help to reduce global warming instead of making the earth temperature increased. Our generation should start taking care of the earth because in the next generation they will suffer if we do not do reduce global warming. Therefore, global warming is a serious issue now. As a business student we are learning it because we need to understand the effect of climate change that will affect us when we have our business and we can start saving the earth.
