The hole in the ozone layer is at its lowest since 1988 and warmer climates could be the reason behind reduced depletion of the protective layer in the Earth's atmosphere, Nasa has found.

The ozone layer's depletion reaches a peak around September to October every year when winter comes to an end in the southern hemisphere, says Nasa.

Ozone depletion occurs during colder climates and this year, the hole was at its widest on 11 September and covered an area of 7.6 million square miles which, according to Nasa, is two and a half times the land area of the US.

By mid-September and through October, National Oceanic and Atmospheric Administration (NOAA) through its ground and balloon-based measurements found that the ozone began to recover.

The three-oxygen molecule is toxic at ground level, but high in the atmosphere, it deflects dangerous ultraviolet rays from reaching Earth's surface.

In 1985, scientists first detected the hole in the ozone layer and realized it was being caused by man-made chlorine and bromine, often found in chlorofluorocarbons (CFCs), compounds used as refrigerants.

In 1987, the Montreal Protocol initiated the phase-out of these chemicals.

As they gradually leave the atmosphere, the ozone hole will heal, and scientists expect it to return to 1980s size by 2070.

"The Antarctic ozone hole was exceptionally weak this year," Paul Newman, chief scientist for Earth Sciences at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said in a statement.

Ozone depletion is on the decline, according to NASA, which has announced that scientists have demonstrated a particular aspect of this via a satellite instrument for the first time.

According to the instrument, which was made by the Jet Propulsion Laboratory, chlorine atom levels are decreasing and with that comes a decrease in their destruction of the ozone layer.

The favorable change is the direct result of international bans on chlorofluorocarbons, NASA says.

Chlorofluorocarbons, more commonly referred to as CFCs, is a type of chemical produced by humans that has a harmful effect on the ozone layer.

An international ban on CFCs is aimed at protecting the ozone layer, and this new data proves that it is working.

In a recent release, NASA explained that the Antarctic winter has seen a 20-percent decrease in ozone depletion versus what was observed in 2005.

Scientists at MIT and other locations have been eyeing the hole in the ozone layer since it came to the forefront in the '80s.

The fear when the hole in the ozone layer was first discovered was that it might lead to harm for humans around the world since we need the ozone layer to protect us from all sorts of deadly things that come from space.

The good news is that scientists have announced that the ozone layer hole has shrunk significantly since 2000.

According to the team of scientists, the ozone hole has shrunk by more than 4 million square kilometers since 2000.

To put 4 million square kilometers in perspective a bit, that it about how large half the area of the contiguous US is.

Scientists have also noted that the healing of the ozone layer hole has also slowed for the first time and the finger is pointed at volcanic eruptions.

When the Montreal Protocol phased out the use of chlorofluorocarbons starting in 1989, scientists expected to see improvements in the Antarctic ozone hole that was opening each spring.

They weren't anticipating anything immediate—instead, improvement was expected within 20 to 30 years of the protocol s implementation.

Ozone recovery occurs through distinct stages, including a reduction in the rate of ozone decline and a leveling off of the depletion.

Only once these are done should we expect to see an ozone increase, termed ozone healing.

Previous studies of the Antarctic ozone have provided evidence that the early phases of ozone recovery have been occurring.

A new paper published in Science presents the first signs ozone healing may be occurring as well.

The Montreal Protocol, which went into effect in 1989, is a rare instance of a global agreement to solve a global problem: the release of vast quantities of ozone-destroying chemicals into the atmosphere.

In the decades since, however, changes in ozone have been small and variable, making it hard to tell whether the protocol is making any difference.

But evidence has been building that the ozone layer is recovering, and a new paper claims to have directly measured the ozone hole gradually filling back in.

During the 1970s and '80s, evidence had been building that a class of industrial chemicals, the chloro-flurocarbons (CFCs), were damaging the ozone layer, a region of the stratosphere rich in this reactive form of oxygen.

The ozone hole spurred countries and companies into action.

As companies developed replacements for CFCs, countries negotiated an international agreement that would limit and phase out their use.

The hole over the ozone layer is finally healing according to new research by the Massachusetts Institute of Technology.

A team in Boston reported the first fingerprints of healing in a paper released to the journal Science.

The September ozone hole has reportedly shrunk by 4 million square kilometers since 2000, when ozone depletion was recorded at its peak.

Findings attribute this positive development to the decline in usage of chlorofluorocarbons CFCs – a chemical compound previously found in dry cleaning processes, old white goods and aerosols.

Undoubtedly the Montreal Protocol has had a huge role to play in this change as it banned the use of CFCs when 46 countries signed it in 1987.

Susan Solomon, the Ellen Swallow Richards Professor of Atmospheric Chemistry and Climate Science at MIT said: We can now be confident that the things we ve done have put the planet on a path to heal…which is pretty good for us, isn t it?

If you were around in the '80s, you might recall the widespread fear over the discovery of a massive hole in the ozone layer over Antarctica.

It's still there, but NASA says 2017 delivered a daintier hole than usual.

The ozone layer acts as a protective shroud over the Earth, blocking out ultraviolet radiation.

NASA likens it to an atmospheric version of sunscreen.

Our planet wouldn't be habitable without the ozone layer to help protect us from the sun.

NASA and the US National Oceanic and Atmospheric Administration have been monitoring the ozone hole since it was first discovered in 1985.

Encouraging images have revealed clear signs the hole in the Antarctic ozone layer is beginning to close.

Recovery of the hole varies year-on-year, due in part to the effects of volcanic eruptions, but scientists have now confirmed the layer which shields life on Earth from the sun s harmful ultraviolet rays is healing.

Specifically accounting for the effects of the eruptions let the team confidently concluded it sees no reason why the ozone hole should not close permanently by the middle of this century.

The findings, published in the journal Science, show the average size of the ozone hole each September has shrunk by more than 1.7 million square miles since 2000 – about 18 times the area of the UK.

The ozone hole begins growing each year when the sun returns to the South Polar cap from August, and reaches its peak in October, which has traditionally been the main focus for research.

The researchers believed they would get a clearer picture of the effects of chlorine by looking earlier in the year in September, when cold winter temperatures still prevail and the ozone hole is opening up.

Back in 1992, a group of 1,700 scientists issued the "World Scientists' Warning to Humanity."

Humanity hasn't been listening very well.

This week, concerned scientists felt compelled to release a new warning 25 years after the original cautioned that "human beings and the natural world are on a collision course."

The original statement warned about ozone depletion, endangered water supplies, ocean habitat destruction, loss of soil productivity, destruction of forests and loss of species.

The forward-thinking warning called for a move away from fossil fuels, a halt to deforestation and a stabilization of the human population.

Pretty much the same things.

US Secretary of State John Kerry speaks in Kigali, Rwanda.

Because of the 1987 Montreal Protocol, NASA was able to call a video about the ozone layer The World Avoided.

In a model for international agreements, the world s nations came together in response to research revealing a dangerous trend of ozone destruction driven primarily by chlorofluorocarbons—used as refrigerants and, yes, propellants in aerosol cans.

There s a common misconception that global warming and ozone depletion are one and the same, but they are separate phenomena with separate causes.

The two phenomena do actually intersect with each other, however.

Apart from destroying stratospheric ozone, some chlorofluorocarbons are tremendously potent greenhouse gases.
