It’s been revealed that there’s a brand new suspect that might be triggering the extreme Arctic melting: ozone-depleting substances.
These used to be present in hairspray, bug spray, and more, but fortunately, scientists found that they created a massive hole in the ozone layer. This triggered a plan to phase such substances out back in 1987, according to Mashable.
Now, after more than three decades, experts made a brand new discovery. Such substances are hurting more than the ozone layer – they are also greenhouse gases, and this means that they contribute to the warning of our planet.
According to the same online publication mentioned above, it seems that these substances have contributed a lot to the Arctic warming.
A study on the situation was just published in the journal Nature yesterday, January 20.
“Gases that deplete the ozone layer could be responsible for up to half of the effects of climate change observed in the Arctic from 1955 to 2005,” according to the study.
The same official notes revealed that “The finding could help to explain the disproportionate toll of climate change on the region, which has long puzzled scientists.”
The study offers hope to tackle Arctic warming in the future
It’s been already revealed that the Arctic is warming at more than twice the average rate of the rest of the globe. It’s interesting to note that this is a phenomenon known as Arctic amplification.
The pace at which this is taking place is really fast and worries experts.
The findings made by this study offer a bit of hope in a really dark scenery about global warming.
“Our findings also have implications for the future because the phase-out of [ozone-depleting substances], which is well underway, will substantially mitigate Arctic warming and sea-ice melting in the coming decades,” the study explains.
