Thwaites Glacier critical tongue breaks up.
The Thwaites Glacier ice shelf is being denuded from beneath, and now open from the front. Loss of this ice shelf would add 2 feet to world sea levels.
The protective tongue is now no longer protective.
First proper cruise of the year, often the best time to do it before the trees obscure views and the hire/leisure boats come out of hiding.
Glorious morning, but more cloud now
