depletion (contributed to air pollution) has long been recognized as a threat to human health as well as to the Earth’s ecosystems. Causes Of Air Pollution: | * a) Ozone - A gas that can be found in two places. Near the ground (the troposphere)‚ it is a major part of smog. The harmful ozone in the lower atmosphere should not be confused with the protective layer of ozone in the upper atmosphere (stratosphere)‚ which screens out harmful ultraviolet rays. Sources: Ozone is not created

earth’s supply of water is found in the atmosphere‚ yet it is this atmospheric water that brings moisture to the surface of the earth and makes it habitable. In the hydrologic cycle‚ water is constantly being moved from the earth’s surface into the troposphere where it gives rise to clouds and precipitation‚ thereby bringing the water back to the surface again. Humidity is defined as the amount of water vapor in the atmosphere. It is measured in several ways. In one method‚ the mass of the water vapor

The atmosphere performs several valuable ecosystem services‚ first protecting Earth’s surface from most of the suns ultraviolet rays. Second‚ allowing visible light and some infrared radiation

Satellite readings of temperatures in the lower troposphere show no warming since readings began 23 years ago. These readings are accurate within 0.01 C‚ and are consistent with data from weather balloons. Only land-based temperature stations show a warming trend‚ and these stations do not cover the entire

Back in the summer of 2008 athletes from all over the world were getting together in China for the 29th edition of the Olympic Games. Just prior to the games inaugural ceremonies there were a lot of concerns about the air quality‚ the contamination‚ and the heat in Beijing. Many athletes wore face masks to prevent getting sick prior to their respective competitions. We might be asking ourselves‚ what does that have to do with climate change? As China and its neighbors economies grow‚ the need
