Massive black hole has been witnessed at Antarctica. It is due to the low temperature there.
The massive hole in ozone is discovered in 1985. It was discovered by Dr. Farman.
massive heat increase, obviosly
There is not actually a hole in the ozone layer. The ozone has been reduced below some limit.
America is trying to recover ozone hole. CFC's have been banned there.
The hole in ozone layer is pretty big. It has been shrinking however.
The ozone hole first appeared when the ozone layer first appeared. The only variable is the "size" of the hole, and the ozone concentration in the "hole". The pole of the Earth that is experiencing winter receives none of the UV that makes ozone (for like a month or more), and ozone naturally decays with time. TThe ozone hole is a normal feature of our ozone layer. It appears each year when it is winter at one of our poles. So it first appeared when the ozone layer appeared. We first noticed the ozone hole in 1985, above Antartica. One forms over the Arctic pole too when it is winter there. They heal closed again once sunlight reaches the pole. Its not so much the presence or absence of an ozone hole, but its size that is important. It is important to look out for the ozone hole
there is no black hole, but a thinning of the ozone levels over the Antarctic every winter. This has been happening for centuries due to a lack of sunlight hitting the oxygen in the area. Because ozone decays so quickly, sunlight must hit oxygen to create more ozone or the thinning occurs. The hole disappears once sunlight hits the area.
A hole in the ice was discovered first in the 1970s. This very large hole has frozen over and reappeared twice since then. It is called the Antarctic ozone hole.In addition, the Antarctic Ozone Hole was discovered in 1985. It is an annual event in Spring.
The discovery of ozone hole was done by Mario Molina. It might have been done in late 1800's.
The name of the hole is ozone hole. It is the thinning of ozone layer.
the ozone depletion has been evident at the poles. Antarctica has the largest ozone hole.
Ozone hole is the thinning of ozone layer. It is due to ODS.
