NASA Says Hole In Ozone Layer Is Closing and Will Be ‘Healed’ By 2050


By -

I’m sure most people didn’t know about the ozone layer back in 1800s but that’s no longer the case. Ozone layer and global warming are easily the most used terms in today’s world. And why wouldn’t they be? The hole in the ozone layer over Antartica grasped the attention of many. Treaties such as the Montreal Protocol (1987), a global treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion

The depletion of ozone layer meant that harmful UV rays could reach the Earth and cause skin cancer and many other diseases. This obviously had to be dealt with since humans love themselves a bit too much. After a lot of research, scientists figured out that chlorine in the atmosphere reacted with the ozone molecules in the presence of sunlight and destroyed the layer. Many of us hadn’t even realized until late ‘80s and ‘90s that we had been pumping chlorine into the atmosphere when we used things like old refrigerators, aerosols etc. It was only three decades ago when we identified this problem as a real environmental threat.

However, it’s never too late – even though most of us thought it was. The ozone layer over Antarctica is finally closing up and scientific predictions suggest that if efforts are continued, it’ll be permanently closed by the year 2050. How wonderful would that be?

Researchers all over the world are congratulating each other because just when the Earth was on the verge of collapsing (slightly exaggerated) it’s now on its way to recovery. A lead researcher at MIT, Susan Solomon, expressed her happiness saying,

We can now be confident that the things we’ve done have put the planet on a path to heal.

The ozone hole is constantly being monitored and measured. Researchers are now using new longitudinal measurements; they’re saying that the hole has shrunk by almost 4 million square kilometres since its highest level in 2000 – roughly 1/2 the size of mainland US.

Ms. Solomon also appreciated the team work saying,

Aren’t we amazing humans, that we did something that created a situation that we decided collectively, as a world, ‘Let’s get rid of these molecules’? We got rid of them, and now we’re seeing the planet respond.

She believes that we can overcome any obstacle if we work together as she concluded her remarks saying,

This is a reminder that when the world gets together, we really can solve environmental problems,” “I think we should all congratulate ourselves on a job well done.

So good job everyone- keep doing what you’re doing and don’t forget to create awareness.
