Global Warming -A Reality

Global Warming -A Reality

Global warming as we were familiar in the past was a slow -growing process, which is not true anymore. It is on a fast increase suddenly and unexpectedly and has become a huge crisis at present due to which planet Earth is not in well condition.

Disasters have always taken place but never in this rate, they have never been this frequent that it has hit us hard recently .e.g. cyclone Larry in northeastern Australia, sections of ice the size of small states disintegrating from Artic and Antarctic, hurricane Katrina in new Orleans and Tsunami in Indonesia, vast numbers of earthquakes that have taken place recently around the globe.The emergency has become commonplace and things are not going right . It is all due to global warming.

There have been heat waves to storms to floods to fires to massive glacial melts, the global climate is in ruins. Scientists had predicted that this would happen, although even they did not anticipate that happening so alarmingly soon. If Earth were to be a living thing, it is having fever right now. It's a result of continued pumping of greenhouse gases into the atmosphere, trapping the heat from the sun and raising earth's temperature. Human activity has been causing it.

It is now here for all of us to see and believe, as contrary to the past when people debated with each other whether the grim forecast was actually true. In the last five years, the debate has quietly come to an end. We thought that slow pace of nature deterioration would give us decades or even centuries to sort out the problem.

But glaciers and nature both are moving with surprising speed. A certain threshold past which slow creep of environmental decay gives way to sudden and powerful collapse. Several Greenland ice sheets have doubled their rate of slide and according to some research that by the end of the century the world could be locked in an eventual rise in the sea-level of as much as 20ft.
