What Is Global Warming???

Not clear yet about this issue?
What is Global Warming actually?

There are many definitions of Global Warming that's given by all the researchers. One source that i have found give the meaning of Global Warming like in the below...
Maybe this article will give us some information about what is global warming real was!

The question about the definition for global warming or in other words "what is global warming" is relatively easy to answer. We hereby lean at the definitions and explanations given in Wikipedia:

Global warming is the observed and projected increases in the average temperature of Earth's atmosphere and oceans. The Earth's average temperature rose about 0.6° Celsius (1.1° Fahrenheit) in the 20th century.

In the current day lexicon of scientists, global warming isn’t really a term of use anymore. The reason for this is that we have come to understand that the effect of the changes we make to our environment will increase the temperature in many locations on the planet, but will also cool a few places. In light of this, the thing you know of as global warming is actually referred to as global climate change. Over all, however, the world is definitely warming.

We need a simple definition for global warming, one that gets the gist without excluding the simplicities. The simplest and most accurate definition is that global warming is the effect greenhouse gases have on the earth’s climate. Greenhouse gases include, but are not limited to, carbon dioxide and methane. While this sounds like a simple definition, there are a couple of key things to realize.

First, global warming is both a natural phenomena and one created by man. Put another way, greenhouse gases are a natural part of the biosphere and would exist if man did not. Indeed, they are a critical component to the existence of life on this planet. If greenhouse gases didn’t exist, the temperature on planet earth would average zero degrees! Naturally occurring gases, however, keep the temperature at a much more livable 59 degrees.

So, if global warming occurs naturally, what is the big panic about? The problem we are facing is the volume of greenhouse gases in the atmosphere. These gases act as thermal blankets for the atmosphere. The more gas in the atmosphere, the thicker the blanket and the less heat escapes. Over the last 80 years, we have been pumping massive amounts of greenhouse gases into the sky. At the same time, we have been reducing forestation around the planet, the primary plant collection that sucks greenhouse gases out of the atmosphere. This double whammy is starting to show negative results, the increased heating of our world.

The ultimate question with global warming is what will happen as the planet heats up. We are already seeing signs with the retreat of the glaciers. Glacier National Park, for instance, is going to have to be renamed since it has already lost 65 percent of all of its glaciers! While the exact end result of global warming is not clear, we can expect major climatic changes over the next 80 years.

Well, you were looking for a definition for global warming. As long winded as this one is, it is as definitive as you are going to find.
