Causes of Global Warming and Greenhouse Effect

Article Summary   by:Fazta    
ª
 
99 Percent of the observed temperature increase over the last 50 years has been due to the improvement in the atmosphere of greenhouse gas concentrations like water vapour, co2 fractional laser (CO2), methane and ozone. Greenhouse gases are the type of gases that give rise to the greenhouse effect (see below). The most important contributing method of obtaining greenhouse gas would be the burning of non-renewable fuels leading to the emission of co2 fractional laser.

When sunlight reaches planet Earth's surface some is absorbed and warms the earth and most of the rest is radiated returning to the atmosphere with a longer wavelength compared to the sun light. Many of these longer wavelengths are absorbed by greenhouse gases inside the atmosphere before they are lost to space. The absorption with this longwave radiant energy warms the atmosphere. These greenhouse gases perform like an image and reflect back to the Earth a number of the heat energy which will preferably be lost to space. The reflecting back of warmth energy by atmosphere is called the "greenhouse effect".

Greenhouse Effect

The major natural greenhouse gases are water vapor, which in turn causes about 36-70% of the greenhouse affect on Earth (not including clouds); fractional co2 CO2, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. It's not necessarily possible to mention that a certain gas results in a number from the greenhouse effect, considering that the influences of the various gases are not additive. Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons.

Greenhouse gases in the atmosphere act like an image and reflect back to the environment a part of the warmth radiation, which could otherwise be lost to space. The higher the concentration of garden greenhouse gases like co2 fractional laser inside the atmosphere, the more heat energy is being reflected returning to the planet earth. The emission of carbon dioxide into your environment mainly from burning of non-renewable fuels (oil, gas, petrol, kerosene, etc.) has been increased dramatically over the past Half a century
