Global Warming Experiment – Is it Getting Hot in Here?

Our atmosphere keeps the Earth’s temperature stable. It lets just the right amount of sunlight through, so the Earth doesn’t get too hot in the summer. It also it keeps warmth from escaping so we don’t get too cold in the winter. In this way the atmosphere acts like a greenhouse. This is called the “greenhouse effect.” It is part of what makes our planet the comfortable place that it is.
