Assessing the Vicious Circle of Ozone Layer and Global Warming
Jul 27, These were meetings that were more than warm-hearted. have something important to say about the relationship between the individual and the respective climate in which . The ozone hole, up there, is a real evil badass. Can ozone depletion and global warming interact to produce rapid climate change The relationship of surface to stratospheric expressions of the NAM can be. Kids learn about the depletion of the ozone layer. Montreal Protocol to try and stop the manufacture and use of CFCs throughout the world. Global Warming.

The cause was tracked down to a group of chemicals, chlorofluorocarbons or CFCs, that were being increasingly used in everyday household and industrial appliances and goods, such as fridges and aerosols. The challenge of removing them seemed great.
They were cheap, incredibly useful and everywhere. And yet, trusting the science, and with international leadership, an agreement — the Montreal Protocol — was signed within two years of the discovery of a hole in the ozone layer in the southern polar region.

In less than a decade, the content of the damaging chemicals in the vital stratosphere began to decline. Now, the hole has stopped growing bigger and is expected to shrink. This will cause an increase risk of sunburn and skin cancer. Skin cancer can be very dangerous.
For this reason you should always wear sunscreen to protect your skin when you are outside in the sun for a long time. Strong ultraviolet rays can also damage your eyes. You can protect them by wearing sunglasses.
What can we do about it? There isn't much we can do about the CFCs that were released prior to the ban, but there are some things we can do: Old refrigerators - If you have a refrigerator made before it probably uses refrigerant made from CFCs.
Get a new refrigerator and be sure to have the old one disposed of properly. If you still have one of these, it's time to get rid of it and buy a new one. Even newer air conditioners use chemicals called HCFCs. Even though HCFCs are better for the ozone, they still contribute to the depletion, so try and use as little air conditioning as possible.
What is the difference between ozone depletion and global warming?
Foam - A lot of foam products contain CFCs. Try and use different packing materials such as crumpled old newspapers. Facts About the Ozone Layer The word "ozone" means smelly in Greek because the gas has a strong odor. These chemicals, including chlorofluorocarbons, methyl bromide, etc.

As these chemicals reach the stratosphere, they destroy the ozone layer. The molecules of these chemicals have the tendency of breaking ozone molecules, thus hampering their ability to trap the ultraviolet-B radiation. The rate at which this layer depletes increases with the decrease in the temperature.
The fact that a fall in temperature increases the rate at which the ozone layer depletes may make a person wonder as to how global 'warming' can cause the ozone layer to deplete, but it does. When we refer to the fact that the global temperatures have soared by 1.
One of the major causes of global warming is the greenhouse effect, wherein a number of greenhouse gases, which are released by natural as well as anthropogenic activities, form a layer in the atmosphere and trap the Sun's radiation, thus making the planet warm.
So the heat that is supposed to be reflected back to the space is trapped within the troposphere. As a result of this, the temperature in the troposphere rises, but the temperature in the stratosphere falls.
