CAUSES OF GLOBAL WARMING

The Greenhouse Effect

The greenhouse effect is the most important cause behind global warming. In fact global warming is known as the greenhouse effect. This phenomenon leads to an increase in the Earth temperature due to certain gases like CO2, nitrous oxide, and methane.

When sunlight reaches Earth's surface some is absorbed and warms the earth and most of the rest is radiated back to the atmosphere at a longer wavelength than the sun light. Some of these longer wavelengths are absorbed by greenhouse gases in the atmosphere before they are lost to space. The absorption of this longwave radiant energy warms the atmosphere. These greenhouse gases act like a mirror and reflect back to the Earth some of the heat energy which would otherwise be lost to space. The reflecting back of heat energy by the atmosphere is called the "greenhouse effect".

Green House Gases

The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide CO2, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%.

It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because 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.

The carbon dioxide is released to the atmosphere where it remains for 100 to 200 years. This leads to an increasing concentration of carbon dioxide in our atmosphere (see above on the right hand side), which in turn causes the average temperature on earth to  raise.

Fig 2: From which sectors do the major greenhouse gas emissions come from? The lower part of the picture shows the sources individually for the gases carbon dioxide, methane and nitrous oxide, respectively.

The higher the concentration of green house gases like carbon dioxide in the atmosphere, the more heat energy is being reflected back to the Earth. The emission of carbon dioxide into the environment mainly from burning of fossil fuels (oil, gas, petrol, kerosene, etc.) has been increased dramatically over the past 50 years. 

THE MAIN CAUSE OF GLOBAL WARMING IS OUR TREATMENT OF NATURE

 

  • Why have warnings about climate change been ignored for more than 20 years?
  • Why were ever more scientific evidence demanded to find the coherence of man-madeCO2 emissions as cause of global warming? Why wasn't common sense reason enough to act?
  • Why can one still today find people who stick their head in the sand and don't want to understand what's going on in the earth's atmosphere?
  • Why do most people refuse to change their personal behavior voluntary in order to reduce CO2 emissions caused by their activities? 

The answer to all these questions is a rather simple one:

In our technology and scientific minded world, we seem to have forgotten that mankind is only a relatively minor part of Nature. We ignore being part of a larger whole.
