Climate Change from the Affected Generation

Halocarbons 27 February 2015 | Posted in Climate 101

A halocarbon is a greenhouse gas and they can be very destructive to molecules like ozone. The most commonly released halocarbons are called Freons which are currently (according to the AR4) are CFC-11 and CFC-12~. All halocarbons except SF6 have at least one chlorine molecule attatched to it. 

With stronger ultraviolet rays in the statosphere, the chlorine molecule(s) breaks(s) off. Then the chlorine molecule floats around until it finds a ozone molecule. Then it steals one of the ozone molecules to create an ordinary oxygen molecule and finds a free oxygen atom. After that, the oxygen atom is released and bonds with the free oxygen atom creating another oxygen molecule.

This is hard to describe in just words so you can look it up on the internet or something but the main point is that with stronger ultraviolet rays, an ozone molecule blocks the ray and heat. In the procsess, the oxygen molecule is destroyed but soon form bonds again to make a brand new ozone molecule.

 With all of the destruction of ozone molecules, we have formed something mostly in both poles that is called the ozone hole. This hole is melting the ice causing the a lower albedo. Albedo is pretty much the amount of heat a surface reflects. We want a higher albedo because is reflects more heat and cools the earth. If we get down to the ocean, the albedo is low causing the earth to warm. The hole is also letting more heat in which is obviously bad.

If you ask my opinion though, I think the ozone hole is a minor cause of climate change. Unfortunately, many people think that it is the main cause of global warming just like they think that trash releases polutants. On the bright side, we are educating you right now so... :)
