Join us as we explore how this "geographic period" at the bottom of the map is actually the key to understanding where our planet has been—and where it is going.

5. The Surprising Ozone Paradox In a counterintuitive twist, the man-made ozone hole has actually shielded the Antarctic interior from global warming. The loss of ozone strengthens the polar vortex, trapping freezing air over the pole and preventing the rapid melting seen in the Antarctic Peninsula.

Have you read our deep dive into this year’s Antarctic #OzoneHole yet? Our latest article unpacks the 2025 development which resulted in the smallest and shortest-lived ozone hole in five years.

The ozone layer is recovering well, thanks to efforts started in 1978 with an agreement between US, Canada, and Norway. It became more global in 1989 when the Montreal Protocol took effect.
Today, “This progress should be celebrated as a timely reminder of what can be achieved when the international community works together to address global environmental challenges...”
Ahem, climate change, anyone?
Anyone???
The 2025 Antarctic #OzoneHole closed today, 1 Dec. – the earliest since 2019 and the smallest & shortest-lived in 5 years. Do you know how #CopernicusAtmosphere tracks ozone hole development? Or how global efforts are making a difference?

I forget what #Conservative talking-head brought it up, but one of them said a year or two ago in an attempt to dismiss concern over #ClimateChange:
"Remember back in the 90's when everyone was concerned about The #OzoneHole? What happened to that?"
Someone on Twitter tried to "Gotcha" me with that question. I responded:
"We fixed it. We banned CFC's nearly world wide and now it's shrinking instead of growing."
They never challenged me again. 😉
