The history of global warming explained
From ancient times it is believed that humans are responsible for climatic changes. This belief was questioned after the discovery of ice age as it was proved that climate changes itself and it has its own cycle. But what was the cause for global warming or the how was global warming discovered?
It was in 1896, Svante Arrhenius, a Swedish scientist came up with his discovery saying that the human activity of burning fossil fuel has added carbon dioxide to the atmosphere of the earth that will raise the temperature of the earth. This discovery was a by product of his research about whether carbon dioxide could describe the causes of Ice ages.
In 1930s it was discovered that the regions of North Atlantic and United States were going warmer and warmer with passage of time. This was thought as the part of nature’s climatic cycle and the cause was unknown. It was then that G. S. Callendar marked this as indication of greenhouse effect. This indication provoked many scientists to look into the matter.
In the next decade scientists were coming up the surprising researches and discoveries about the temperature of the planet, calling it as global warming. In 1967, the calculation of scientist showed that there might be rise in temperature of earth by few degrees within the next century. Actually speaking the next century speculation was far off as the planet had already started experiencing the effect of sudden climatic change. At this stage scientists believed that there was need for more research and find out what will this global warming result into?
Scientist was of opinion that finding a single solution to this problem would be of no use as the climate is responding to many changes. It was a controversy that whether global warming is a natural climatic cycle or the result of human activities. The climate was on a very delicate balance and even a small shift might change the future of the planet. Antarctic and Greenland showed great changes in temperatures which was again an indication of global warming.
In late 1970s the global warming was showing the evidence of its presence and there was a warning from scientists to reduce the emission of green house gasses. The first climatic change was in 1988 and has the hottest record. The prediction of scientists of 1980 about the temperature of planet was proved to be correct. Today humans, wildlife and nature are giving proof of effects of global warming by one or another way or suffering.
