What are the effects of global warming ?
Death March of the PenguinsScientists blame global warming for the declining penguin population, as warmer waters and smaller ice floes force the birds to travel further to find food. “Emperor penguins ... have dropped from 300 breeding pairs to just nine in the western Antarctic Peninsula.” [National Geographic] [MSNBC]
Farewell to FrogsAn estimated two-thirds of the 110 known species of harlequin frog in Central and South America have vanished since the 1980s due to the outbreak of a deadly frog fungus ... brought on by global warming. Scientist J. Allen Pound: "Disease is the bullet killing frogs, but climate change is pulling the trigger.” [National Geographic]
Farewell to the Arctic FoxThe White Arctic Fox used to rule the colder climes, but as temperatures warm up, its more aggressive cousin, the Red Fox, is moving North and taking over. [Wired]

What is Global Warming?
Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent

Question: What Causes Global Warming?
Answer: Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.
The Consequences of Global WarmingAs the concentration of greenhouse gases grows, more heat is trapped in the atmosphere and less escapes back into space. This increase in trapped heat changes the climate and alters weather patterns, which may hasten species extinction, influence the length of seasons, cause coastal flooding, and lead to more frequent and severe storms
Greenhouse Gases and Global WarmingWhile many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gases. By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases, because fewer trees means less carbon dioxide conversion to oxygen.
During the 150 years of the industrial age, the atmospheric concentration of carbon dioxide has increased by 31 percent. Over the same period, the level of atmospheric methane has risen by 151 percent, mostly from agricultural activities such as raising cattle and growing rice
