Global Warming - Causes That Contribute

Increasing temperature, rising sea level and increasing the number of diseases are some of the effects of global warming. But do you know the causes that are leading towards these situations? Here we are going to discuss some of the causes that lead to these situations.
Emission of greenhouse gases is considered to be the main reason of climate warming. Water vapor, carbon dioxide, methane, nitrogen oxides, and some engineered chemicals such as chlorofluorocarbons are the greenhouse gases. Most of these gases occur in the atmosphere naturally, but due to the widespread burning of fossil fuels by growing human populations, the level of greenhouse gases emission has increased a lot. In order to reduce the effects of global warming, reduction of greenhouse gas emissions has become a primary focus of environmental programs around the world.
Smog and poor air quality is a burning environmental problem, especially in large metropolitan cities. The primary constituent of Smog is the ground level ozone which is formed by a chemical reaction of carbon monoxide, nitrogen oxides, volatile organic compounds, and heat from sunlight. Pollutants that contribute to smog come from a lot of sources, such as smokestack emissions, vehicle emissions, paints, and solvents. The reaction to create smog needs heat and smog problems are the worst in the summer.
Moreover, the pollutant releases from the industrial sector and electric utilities contribute greatly to environmental problems and lead to many environmental issues. Emissions from vehicles also contribute to smog, low visibility, and various greenhouse gas emissions in the environmental atmosphere and thus, contributing towards the global warming.
End global warming before it becomes a real threat to human life. For latest updates on climate warming please visit http://www.webgreenworld.com
