Why are scientists sounding fresh alarms on ‘doomsday glacier’ Thwaites?

Firstpost  

The Thwaites glacier around the US state of Florida has been given the moniker due to its huge size and the possibility of what could happen if it all melts — seas would rise more than two feet, leading to a climate change catastrophe. The Thwaites glacier has been given the moniker due to its huge size and what could happen if it all melts – seas would rise more than two feet and thus lead to a climate change catastrophe. “Thwaites is really holding on today by its fingernails, and we should expect to see big changes over small timescales in the future – even from one year to the next – once the glacier retreats beyond a shallow ridge in its bed,” Robert Larter, a marine geophysicist and one of the study’s co-authors from the British Antarctic Survey, said as per CNN. Alastair Graham, the USF marine geophysicist who led the study, was quoted by Business Insider as saying “Just a small kick to Thwaites could lead to a big response.” Anna Wåhlin, a co-author of the study and a professor of physical oceanography at Sweden’s Gothenburg University, told NBC News agreed.
