Greenland: The Icy Giant at the Center of a Warming World Why Iceland is Greeny?           Far beyond the reach of most people’s daily thoughts lies Greenland, a vast and remote Arctic island that is quietly becoming one of the most geopolitically, environmentally, and economically important places on Earth. Though it’s part of the Kingdom of Denmark and home to fewer people than a small European microstate, Greenland’s immense landmass, strategic location, and untapped wealth have made it the subject of increasing global attention. A Vast and Frozen Land           Greenland is the largest island in the world, more than three times the size of France. With a population of only 56,000, it's one of the most sparsely populated places on Earth.

What is Global warming?                Global warming refers to the long-term increase in Earth’s average temperature due to human activities, initially the release of greenhouse gases into the atmosphere.             Greenhouse effect is due to global warming.  Greenhouse effect is defined as the progressive warming up of the earth surface due to high concentration of manmade carbon dioxide in the atmosphere.  It is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Global warming                The gases such as carbon dioxide (CO 2 ), Methane (CH 4 ), and Nitrous Oxide (N 2 O), trap heat from the sun, leading to a gradual rise in temperatures worldwide.  While some level of greenhouse gases is necessary to maintain Earth’s temperature, excessive emissio...
