Warmer Atlantic, Wetter Summers

The BBC headline is succinct if  nothing else: Scientists blame warmer Atlantic for wet summers

This being the BBC I expected the usual hysterical story. A classic Richard Black-style piece that manages to pin the blame on global warming caused by CO2, and ending with a dig at those who dare to deny the self-evident truths revealed by the high-priests. But no, the odious Richard Black is no longer on board the good ship BBC, and the story hasn't been handed over to Harrabin either.

Instead we get a reasonably calm piece that links wetter UK summers to warming in the Atlantic, which is in turn linked to the Atlantic Multidecadal Oscillation. What's more the story even points to periods of warming and cooling which don't coincide with the hockey stick ever upward rise of temperature and CO2. Indeed the compulsory link to CO2 is very low-key, these decadal oscillations are related to a number of natural factors and ...possibly now also influenced by manmade greenhouse gases.

Very low key, but hopefully a sign that the odious Richard Black's poisonous influence is starting to pass.
