PBS Terra: *A Hidden Antarctic Tipping Point May Have Just Been Triggered*

"Something unexpected and potentially irreversible is changing #Antarctica and scientists finally know why.

Over the past few decades, researchers have tracked the mysterious growth and sharp decline in sea ice in Antarctica. But a few years ago a troubling discovery was made that could upend global ocean circulation, push one species of penguin to extinction, and change our planet’s climate forever.

In this episode of Weathered, Maiya May looks into the role sea ice plays in our global climate, and the threat that its disappearance poses to our natural world.

From emperor penguins, to sea level rise, to the slowing of the AMOC, these seemingly inconsequential chunks of floating ice could hold the key to our survival. And their loss could be a sign that we’ve crossed a tipping point in an already delicate region of our planet."

How a Melting Glacier Could Affect Tens of Millions Around the Globe

Scientists spent the first weeks of the year on an expedition to Antarctica to study Thwaites Glacier, which is melting at an alarming rate. If it breaks apart entirely, it could push up global sea levels by two feet over the course of several decades, affecting tens of millions worldwide, according to a New York Times analysis.

A collapse of the Thwaites Glacier in Antarctica would sharply accelerate sea-level rise in coastal cities.
