Are holes in the ozone layer caused be burning fuels?

Answer 1

Not at all. The major source for the thinning area that we call a hole, which occurs over Antarctica during it's winter months is primarily due to a lack of energy (sunlight) on that area. No reputable science group and no scientist disagrees with this. We know the "hole" has been occurring for centuries. What some people believe is that the use of solvents and certain chemicals may have a negative affect on this layer and helping thin this area more in recent years.

There are two holes which each occur annually. One over the Antarctic during their winter and the same in the Arctic during it's winter. These have happened since well before man made any chemicals. The items blamed for the hole by some is heavier then air and is only found in the ozone layer in extremely low volumes. There is no thinning over most of our planet, including areas where humans actually live and use CFC's.

Burning of fossil fuels is blammed (by some) for the 0.2 degrees of warming we have seen the past 200 years. We have seen 11 degrees of warming though over the past 6000 years.

Answer 2

No, holes in the ozone layer are mainly caused by human-made chemicals called chlorofluorocarbons (CFCs) and other ozone-depleting substances, not burning fuels. These chemicals can break down ozone molecules in the stratosphere, leading to a thinning of the ozone layer. Efforts to reduce and eliminate these substances have been successful in helping to heal the ozone layer.
