Blocking highs and jet stream kinks

New studies suggest that the weather in far off Greenland, one of the fastest warming parts of the Earth, is affecting the rainfall patterns in Britain. This is linked to the extremely wet summers of 2007 and 2012.

Sheffield University, checking data back to 1851, found that since the 1980s there has been an increase in the number of summer high pressure blocking systems that become anchored over this vast island ice sheet. The result has been to drag warm air over Greenland causing melting on a much-increased scale.
