With enough evidence, even skepticism will thaw

Half a decade before he took this trip to the
farthest reaches of the north, Andreas Muenchow had his doubts about
whether warming temperatures were causing one of the world’s great
platforms of ice to melt and fall apart.

He even stood before Congress in 2010 and balked on whether climate
change might have caused a mammoth chunk of ice, four times the size of
Manhattan, to break off from this floating, 300-square-mile shelf. The
University of Delaware oceanographer said he wasn’t sure. He needed more
evidence.

But then the Petermann Ice Shelf lost another two Manhattans of ice in
2012, and Muenchow decided to see for himself, launching a project to
study the ice shelf intensively.
