What gets us into trouble is not what we don’t know
It’s what we know for sure that just ain’t so.
Mark Twain

 

Image of Earth from spaceAn assumption about Global Warming that just ain’t so: The Earth is so big we can’t possibly have any lasting harmful impact on the Earth’s environment. This may have been true at one point but not anymore, the atmosphere is so thin that we can change it’s composition (Al Gore, An Inconvenient Truth, 2006).

 

How does it happen?

  • Solar radiation in the form of light waves passes through the atmosphere
  • Most of this radiation is absorbed by the Earth and the planet is warmed by the radiation
  • Some energy is radiated back into space by the earth in the form of infrared waves
  • Some of this outgoing infrared radiation is trapped by the earth’s atmosphere; thus, helping to warm the Earth and keep the temperature of the planet relatively balanced and livable
  • The problem is that the thin layer of the earth’s atmosphere is being thickened by pollution and more and more of the outgoing infrared radiation is trapped and so the planet is heating up.

Scientific opinion on climate change is that the Earth’s climate system is unequivocally warming and it is more than 90% certain that humans are causing it through activities that increase concentrations of greenhouse gases in the atmosphere, such as deforestation and burning fossil fuels (Wikipedia, 2012).
