Global Warming

What is Global Warming?
Global Warming is a horrible problem on Earth. Global warming is when the gases gather above the Earth on the atmosphere. These gasses are caused by us. Global Warming is also known as the greenhouse effect because the gases that are gathering above the earth make the planet comparable to a greenhouse.  By trapping heat near the surface of the earth, the greenhouse effect is warming the planet and threatening the environment.

What are the causes of Global Warming?
Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket, trapping heat and warming the planet. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases, such as methane and nitrous oxide.

What are the effects of Global Warming?
Global Warming can have a lot of horrible effects on Earth. First of all the sun has a lot of radiation. If this radiation isn't trapped in the atmosphere it can give us cancer and other deathly sicknesses. Also this heat makes temperatures on Earth rise very quickly, more than usual. Also the extra heat causes the ice in the north and south poles to fall down and melt. This leaves animals, such as polar bears and seals, without a habitat, without a home.
