Welcome to planet Earth

Earth is heated by sunlight. Most of the Sun's energy passes through the atmosphere, to warm the earth's surface, oceans and atmosphere. For thousands of years, the Earth’s atmosphere has changed very little. Temperature balance of heat-trapping greenhouse gases have remained just right for humans, animals and plants to survive. But today, we’re having problems keeping this balance.

Because we burn fossil fuels to heat our homes, run our cars,produce electricity and manufacture all sorts of products, we’re adding more greenhouse gases to the atmosphere. By increasing the amount of these gases, we’ve enhanced the warming capability of the natural greenhouse effect.
