What else can I help you with?
What year do scientists think the ozone layer will have rebound?
Scientists hope the ozone layer will have recovered by around 2050.
How do you increase the ozone layer by spreading co2?
Carbon dioxide, CO2, has very little to do with the ozone layer. The ozone layer will repair itself if we stop damaging it, which we have, by banning CFCs, chlorofluorocarbon gases, the chlorine of which was destroying the ozone molecules. Scientists hope the ozone layer will be completely restored by 2060.
What is the proof that freon causes global warming?
Freon and similar gases like chlorofluorocarbons and halons have only a small influence on global warming. They are much more important for destroying ozone in the ozone layer. Most of these gases are no longer emitted into the atmosphere, but they have a life span of up to 70 years, so they are still damaging ozone. Scientists hope the ozone layer will have repaired itself by 2060.
How does hairspray destroy the ozone layer?
Not any more. The CFCs that were used as aerosols in the 1980s are responsible for the depletion of the ozone layer. These have been phased out and scientists hope the ozone layer will have recovered by about 2060.It emits gases that damage the ozone layer.
Is the ozone layer breaking up because temperatures are increasing?
No, the ozone layer has been breaking up because of man made gases (CFCs) in the atmosphere. The chlorine in those gases attacks and destroys ozone. These gases, which can stay in the atmosphere for up to 75 years, are no longer emitted. Scientists hope that the ozone layer will be restored by 2060.
What can we do to help protect the ozone layer?
Ozone layer can be protected by minimizing pollution. Gases like CFCs (chlorofluorocarbons) and BFCs (bromofluorocarbons) contribute to the degradation of the Ozone Layer by increasing the amount of chlorine and bromine in the atmosphere. Along with NO and N2O (nitric and nitrous oxide), and OH (hydroxyl), these free-radical catalysts destroy ozone in the stratosphere. Minimising the use of CFCs in manufacturing and propellants is an ongoing effort in the mitigation of man-made damage to the ozone layer. Using more reactive hydrochlorofluorocarbons (HCFCs), the hope is that these chemical compounds will not survive the journey to the stratosphere, thereby reducing the damage they can do- however, as they are still capable of causing damage, their use is being reduced too. The issue with CFCs is that they can survive for decades in the atmosphere, and remain unchanged by their interaction with ozone. Even if we stop all use of CFCs, it may still take centuries for the ozone layer to return to normal. However, the rate at which the ozone layer is being depleted has slowed significantly in recent years.
Why can losing the ozone layer be bad?
If we lose the stratospheric ozone layer, harmful ultraviolet rays from the sun will be allowed into Earth's atmosphere, causing plants, animals, and humans to have skin cancer, mutation, and other severe problems. If the ozone layer is gone, we will all die. Fortunately, as long as we have sunlight and oxygen we will have this layer. The thinning we currently see in the ozone layer occurs only at the poles and then only in the winter months. Scientists hope that the holes will be completely repaired by 2050.
Can the ozone layer heal itself?
Ozone is continually made and destroyed by the Sun. If we'll quit messing with it by making inert molecules with chlorine or bromine, and stop dumping large quantities of water vapor at high altitude, the ozone layer will recover.It will still have an ozone hole, once a year, when it is late winter / early spring at a pole. That's Nature.
How is the ozone layer changing?
Yes. After the Montreal Protocol, countries gradually phased out the production of CFCs. Chlorofluorocarbons (CFCs) that were used in refrigerators and aerosols were the main destroyers of the ozone layer. The ozone layer is now no longer depleting. Scientists hope that it will have completely restored itself by 2060.
What can countries do to help the ozone layer recover?
They can get together and agree to stop producing CFCs (chlorofluorocarbons). They did this already in Montreal in 1987, and the ozone layer is now healing itself and scientists hope if will be fully recovered by 2050, if we don't discover another destroying chemical.
Why is chlorofluocarbon a harmful gas?
Chlorofluorocarbon (CFC) is a harmful gas because it destroys the ozone layer. It has largely been phased out now, but it remains in the atmosphere for many years and is very destructive. It takes almost seven years for it to rise and move up to the ozone layer where it releases chlorine. This chlorine destroys ozone and keeps reforming and destroying more. Scientists hope the ozone layer will be restored by 2060.
How can you retify the ozone layer depletion?
The issue of depletion of the ozone layer is mostly a naturally occurring event and has always occured during the end of the winter months at both poles. Man's involvement in this issue has been largely corrected through the banning of CFC's. As long as we have oxygen in our atmosphere and a sun to convert O2 into O3, we will have an ozone layer. Scientists hope that the ozone layer may have completely recovered by 2060.
