It relates to an average increase in temperature of Earth, which successively creates changes in climate. A humid earth may trigger transformation in rainfall patterns, a wide spectrum of effects on plant, a surge in sea level, changes in the life pattern of humans and wildlife. Scientists are of the view that main reason for global warming is due to human activities. One of the evidence of global warming may be observed at Montana’s Glazier National Park in U. S. A , where smaller than of 30 of the original 151 glaziers remain and that too with the reduction in size.
As per meteorological statistics, the average global temperature has swelled by 1 degree Fahrenheit since the commencement of this century. According to scientists, if greenhouse gas emission is not properly controlled, then there is a possibility of increase of global temperature by 2 to 8 degrees at the end of the 21st century. Global warming comprises of the following activities viz. lengthening of growing seasons , drastic change in the environment , thawing of permafrost , earlier break-up of ice on lakes and rivers , shrinking of glaziers , early flowering of trees and shifts in plant and animal ranges .
3. CLIMATE CHANGE Climate can by explained as the total of all weather happening over a period of years in a particular place. The term climate includes regular weather sequences like spring, winter, fall and weather, average weather conditions and special weather incidents like floods, tornadoes, hurricanes etc. Climate inform one what would be the pattern of climate in the place usually one reside. For instance, New Orleans is having a humid climate, San Diego is famous for its mild climate, Seattle is renowned for its rainy climate and Buffalo is prominent of snowy climate.
It is to be observed that though all the above places are situated in America, but still they are having dissimilar climate . Hence, climate is not identical for whole country and it may differ. 4. GREENHOUSE GAS EMISSION: Arrhenius discovered that all the coal which was being burned was actually affecting Earth’s outer atmosphere due to huge amount of emission of carbon dioxide and other pollutant gasses. Thus, the so emitted carbon dioxide and other gasses had trapped solar heat in the atmosphere like as the glass roof and fortifications of a greenhouse trap heat.
Arrhenius discovered that ever increasing industrialization would definitely going to add much more gasses to the Earth’s atmosphere, making global temperatures to swell to several degrees in the years to come. Carbon dioxide which is the major greenhouse gas transpires naturally, as do other greenhouse gases like nitrous oxide, methane and water vapor. It is to be noted that without greenhouse gasses, the earth will be too cold to habitat. U. S. A, China and European Union emit almost 50% of the world’s carbon dioxide and other greenhouse gases. U. S. A, Australia and Canada have the highest per-capita emissions.
