Recent dramatic thinning of largest West Antarctic ice stream triggered by oceans
[1] A growing body of observational data suggests that Pine Island Glacier (PIG) is changing on decadal or shorter timescales. These changes may have far-reaching consequences for the future of the West Antarctic ice sheet (WAIS) and global sea levels because of PIG’s role as the ice sheet’s primary...
