Evidence of Antarctic glacier's tipping point confirmed for first time (phys.org)

The article is surprisingly scare mongering and empty of actual details and full of generic snow landscape photos.

Anyone can fill in what a glacier "tipping point" is and what is the historic data around this particular glacier?

not really sure the certainty of the click-bait headline 'tipping point confirmed' actually is backed up by the content of the article...whole lot of 'might','could' and 'has the potential too'

>>"Should the glacier enter unstable irreversible retreat, the impact on sea level could be measured in metres, and as this study shows, once the retreat starts it might be impossible to halt it."
