Our planet is warming. The last 10 years have been the warmest since records have been kept and scientists announced that in the future will be even hotter. Most experts agree that humans have a direct impact on the heating process, generally known as the "greenhouse effect".
The greenhouse effect is a natural condition of the earth's atmosphere. Some gases, such as water vapor, carbon dioxide (CO2) and methane are called greenhouse gases because they trap heat from the sun in the lower layers of the atmosphere. Without them, our planet would freeze and nothing could live in it.
As the planet warms, the polar ice caps melt. Besides the heat of the sun when it comes to the poles, is reflected back into space. The melting ice caps, the lower the amount of heat that is reflected, which will cause the earth to warm up even more. Global warming will cause more water to evaporate from the oceans. The steam acts as a greenhouse gas. So there will be more warming. This contributes to the so-called "leverage effect".
