As expected, the ozone hole near the Earth's South Pole, grew again during 2003. This year's hole, slightly larger than North America, is larger than last year, but smaller than the record reached on September 10, 2000. Ozone is important because it protects us from the damage of ultraviolet radiation from sunlight.
How does the sun affect the weather? The Sun is the energy source of all life on Earth. Most of the solar energy arrives on Earth in the form of light and heat. The climate depends on the way in which this energy is distributed between the atmosphere and the earth's surface. The weather is warmer where more energy reaches the surface, and colder where less.
