Time Live 19 July 2012.
A massive iceberg twice the size of Manhattan has broken off of a glacier in Greenland, according to NASA satellite imagery, in what could be the latest indication of global warming.
The images released Wednesday show the massive chunk of ice breaking off of the Petermann Glacier on the northwestern coast of Greenland. The glacier produced a similar ice island twice as large in 2010.
(Editorial note: Of course, this is what glaciers do – slide down slopes into the sea. The real issue, I think, is whether this process has speeded up in response to long-term climate change. This is not addressed in this article, but it is to some extents here: http://ajw.asahi.com/article/behind_news/social_affairs/AJ201207180031)
