Global Warming Defined

Here's a small presentation I made which serves as a general guideline as to what the global warming phenomenon (also referred to as climate change) is, how man is responsible for rises in the earth’s natural temperature, how the world’s ecology is slowly changing for the worse, and what we, as individuals, can do to lessen the impact of this unfortunate global issue.

A lot of people wonder how La nina and El nino relate to global warming. They're cycles of extreme cold and extreme heat and they come about every few years, even during global warming. While the earth may get warmer one year and cooler the next, the temperatures are still a lot higher than they were, say, a hundred years ago, or the last 200,000 years ago which goes on to prove global warming is not joke.
