Re: The Ozone

Ozone shmozone!!
It is most likely a case of history repeating itself
Look @ the volcanic age, Ice age etc
For a prime example
We all know that salt melts ice
And where does 99.9% of salt live
I will tell you, it lives in the sea, where there are ice caps etc

Re: The Ozone

Do you know that salt is used on downhill ski runs to ice them up

Re: The Ozone

You may be referring to Salting
[quote=http://en.wikipedia.org/wiki/Alpine_skiing#Salting]Salting
Chemicals can be applied to the snow surface in order to harden the course. The most common chemicals used are sodium chloride, calcium chloride, urea, ammonium nitrate, and potassium nitrate. This "salting" is done mostly when the snow is wet and slushy. When a race course is salted, the salt crystals break up into ions. These ions lower the freezing point of the snow, which hardens the surface. This provides a dense layer of snow with a consistent surface throughout the course, making the race more fair for athletes skiing later in the race.
