Global Warming: Behind the name

There are two reasons why Global Warming is called Global Warming.

1. The ice sheets and glaciers store ancient methane, trapped in ice millions of years ago. When they melt, the methane is released into the atmosphere, rising global temperatures drastically, changing life as we know it.
2. Human released carbon dioxide, having no where else to go, thicken the ozone layer. The greenhouse effect is damaged, and more of the sun's hot rays are trapped in the carbon-thick ozone, heating up the Earth slowly, until there's no going back to change it.

By the time 2050, carbon dioxide levels will be too high to stop. People in the south, in Calafornia and Mexico will flee, because of drought and death, to New York City and other green cities that can sustain themselves, independent. Overpopulation will be a major problem, and rising sea levels will flood the coasts, destroying states.
