Marine biologists have just identified – and explained – a climate change paradox: while most fish are migrating towards the poles as the world’s oceans warm, one part of a potentially valuable commercial fishery is heading in the wrong direction – and perhaps to extinction. Why? Once again, the finger of suspicion points to global climate change, and its impact on ocean tides and currents.

A 42-square mile chunk of the Arctic’s largest remaining ice shelf has broken off in northeast Greenland, prompting scientists to warn that record-breaking temperatures are accelerating ice loss. Satellite images reveal that a section broke off the Nioghalvfjerdsfjorden glacier and shattered into many small pieces. The section was floating before it broke off so will not directly cause the sea level to rise but scientists said this would still probably occur because ice lying on land was likely to flow more quickly into the ocean. The Geological Survey of Denmark and Greenland (GEUS) said: “The last few years have been incredibly warm in northeast Greenland and this appears to be a progressive disintegration.” A study last month revealed that Greenland had lost a record 532 billion tonnes of ice last year, exceeding the previous record melt in 2012 by 15 per cent. Melting of the Greenland ice sheet is one of the main causes of the global rise in sea level, contributing about 0.76mm per year out of the total of about 3.5mm annually from 2005 to 2017.
