Chatgpt generated global montage showing that ferry electrification is no longer confined to one region or one operating model.

Ferry Electrification Is Still Surging Even After a Key Industry Statistic Was Corrected

A widely cited claim that 70 percent of ferries on order used batteries appears overstated.
The corrected estimate points to roughly two-fifths of ferry orders using battery-electric or battery-hybrid drivetrains.
Fixed routes, repeated voyages and terminal charging make ferries one of shipping’s best fits for electrification.

Sea Ice In Antarctica Was Expanding Until 2016. Then Everything Changed. - CleanTechnica

Why Antarctica's Sea Ice Reversal After 2016 Has Scientists Looking Below the Surface

A new PNAS study uses nearly two decades of under-ice Argo float data to explain Antarctica’s sea ice reversal.
Surface freshening from precipitation helped sea ice expand by trapping warmer water below.
After 2015, stronger wind-driven upwelling brought stored heat upward and contributed to sharp sea ice loss.
