Where are there holes in the ozone layer today?
What we call the ozone hole is a thinning of the protective ozone layer in the stratosphere (the upper layer of Earth’s atmosphere) above Antarctica that begins every September.
Which country is under ozone hole?
As the ozone hole over Antarctica has in some instances grown so large as to affect parts of Australia, New Zealand, Chile, Argentina, and South Africa, environmentalists have been concerned that the increase in surface UV could be significant.
Is the ozone hole still open?
CAMS scientists confirmed at the end of last month that the 2021 Antarctic ozone hole closed on 23 December, only a few days earlier than in 2020.
How is the ozone layer in 2021?
Similar to last year’s season, the ozone hole in 2021 will be one of the largest and longest-living ones on record, coming to a close later than 95% of all tracked ozone holes since 1979.
What does the ozone layer look like in 2021?
In late October, NOAA and NASA scientists reported that the ozone hole that develops in the stratosphere over Antarctica every spring was larger and deeper than average in 2021 thanks to a colder-than-average winter.
Why is Australia Sun so strong?
Australia’s unusually harsh sunshine results mainly from its location in the Southern Hemisphere. The elliptical orbit of the Earth places the Southern Hemisphere closer to the sun during its summer months than the Northern Hemisphere during its summer.
Did the ozone hole close in 2020?
The record-breaking 2020 Antarctic ozone hole finally closed at the end of December after an exceptional season due to naturally occurring meteorological conditions and the continued presence of ozone depleting substances in the atmosphere.
Has the ozone hole over Antarctica closed?
It closed on 23 December, the third latest date after 1999 and 2020. The extent and longevity of the 2021 ozone hole can be explained by very cold temperatures in the stratosphere and a very stable polar vortex. This video shows the evolution of the 2021 Antarctic ozone hole.
How long did it take to fix the ozone layer?
The ozone layer is slowly healing. In 1987, all the countries in the world promised to save the ozone layer together. And, it has worked, in parts. According to the latest Scientific Assessment of Ozone Depletion, completed in 2018, portions of the ozone layer have recovered at a rate of 1% to 3% per decade since 2000.
What country has the strongest UV rays?
