The Ozone functions as a natural sunscreen for the Earth, protecting us and our planet from harmful UV radiation. The chlorine in CFCs breaks down the molecules within the ozone layer and created a
A recent report from the United Nations included some dire news about the fight against climate change. It said current pledges from countries to curb emissions will probably not stop global warming from going over 1.5 degrees Celsius in the next few decades – the point at which some damage may be irreversible, and tens of millions may face life-threatening effects of climate change. And all that’s assuming countries actually follow through on their current pledges.
The production of CFCs and other harmful chemicals plummeted. CFC consumption went from 800,000 metric tons in the 80s, to an estimated 156 metric tons in 2014. The EPA suggests that by 2050, the ozone layers will be back to where it was in 1980. So today, the damage to the ozone from the last century has been reversed and healing the Ozone even bought the world valuable time in the fight against climate change.
Another difference was the urgency: the threat of radiation and potential skin cancer from the Ozone hole was a much more immediate danger than something that, to many people, feels like it’s still decades away. ExxonMobil is still battling court cases over its role here. They claim there is an “orchestrated campaign that seeks to delegitimize ExxonMobil by misrepresenting [their] position on climate change and related research to the public."
"It appears that we’re waiting for some senators in U.S. Congress to conclude before we can consider this issue properly," said Ian Fry, Tuvalu delegate to the United Nations Climate Change Conference."It’s an irony of the modern world that the fate of the world is being determined by some senators in the U.S. Congress."
