The purpose of the Montreal Protocol was to protect the ozone layer by phasing out the use and production of various ozone depleting chemicals that were causing the layer to thin and dissipate. Industry objected at first, but scientists and environmentalists prevailed.
The next layer up is called the stratosphere. In the stratosphere, temperature increases with altitude. This is because of ozone. When the ozone in this layer absorbs UV light from the sun, it increases in temperature. In the mesosphere, ozone concentration decreases. This means there is less absorption of UV light in this layer of atmosphere.
