Global Warming "A Major Issue of Today"

Global Warming as the name tells that it is a thing which is global. It is affecting our whole planet EARTH as well as other planets also. Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and it is in continuation.

What is Global Warming?

Earth's atmosphere contains certain gases called greenhouse gases which act to keep the lower layers of the atmosphere warmer. “Global Warming” is the expected slow, gradual warming of the lower layers of the Earth’s lower atmosphere by the slowly increasing concentrations of man-made greenhouse gases. These gases trap infrared radiation, which is the “heat radiation” that cools the Earth.

How serious will global warming be?

We don't know for sure, and there is much debate in the climate research community over this question. The consensus of opinion is that a warming of about 0.2 degrees Celsius every 10 years is expected for the next 100 years or so.

Global warming has become perhaps the most complicated issue facing world leaders. On the one hand, warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests. On the other, the technological, economic and political issues that have to be resolved before a concerted worldwide effort to reduce emissions can begin have gotten no simpler, particularly in the face of a global economic slowdown.

After years of preparation for climate talks taking place in Copenhagen through Dec. 18, 2009, President Obama and other leaders announced on Nov. 15 what had already become evident — that no formal treaty could be produced anytime soon. Instead, the leaders pledged to reach a placeholder accord that would call for reductions in emissions and increased aid to help developing nations adapt to a changing climate and get access to non-polluting energy options.

Thanking You,
