Scientists didn't knew ozone layer before 1880. It is because of lack of technology at that time.
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.
When was the year when you discovered the ozone layer disappearing?
In 1985, we discovered. It was done by Dr Farman.
Is there any improvement of ozone layer in recent year?
Yes, there is. Ozone layer is replenishing.
What year did the hole in the ozone get discovered?
The discovery of the hole in the ozone layer was officially announced in 1985. British scientists reported that the ozone layer above Antarctica was significantly depleted. This discovery led to global concern about the effects of ozone depletion on the environment.
In 1985 was there a hole in the ozone layer?
The ozone layer is the portion of the atmosphere that filters out most of the dangerous UV waves that hit the Earth from the sun. In 1985, scientists discovered a very large hole in the ozone layer above Antarctica.
What year do scientists think the ozone layer will have rebound?
Scientists hope the ozone layer will have recovered by around 2050.
When was the ozone layer discoverd?
The ozone layer was discovered in the year 1913 by the scientists Charles Fabry and Henry Buisson.
In what year do scientists believe that the hole in the Ozone Layer over Antarctica first appeared?
Right after the Great Oxidation Event, when the ozone layer first formed. About 500 million years ago.
When did scientists find a hole in the ozone layer?
The ozone layer was discovered in the year 1985. During that period large amount of CFC's were used without knowing the adverse effect of these fatal chemicals. In 1985 scientists discovered that appreciable thinning of ozone layer is happening over the antarctic region. And thus steps for its recovery were made into action.
In which year was the ozone layer biggest?
The ozone layer covers the entire planet twice a year, every year. That is when it is biggest.
When was the year when you discovered the ozone layer disappearing?
In 1985, we discovered. It was done by Dr Farman.
Is there any improvement of ozone layer in recent year?
Yes, there is. Ozone layer is replenishing.
How fast is the ozone layer growing each year and why?
The ozone layer is growing slow. This is due to ozone depletion by CFC's.
What year did the hole in the ozone get discovered?
The discovery of the hole in the ozone layer was officially announced in 1985. British scientists reported that the ozone layer above Antarctica was significantly depleted. This discovery led to global concern about the effects of ozone depletion on the environment.
In 1985 was there a hole in the ozone layer?
The ozone layer is the portion of the atmosphere that filters out most of the dangerous UV waves that hit the Earth from the sun. In 1985, scientists discovered a very large hole in the ozone layer above Antarctica.
Has size of the hole in the ozone layer changed in recent year?
Yes, it has. Size of ozone layer changes according to the use of CFC's.
What is the size of the ozon layer this year of 2008?
The size of ozone layer in year 2008 was moderate. It was recovering.
