I rolled back [1] Abe Froman; apologies for not doing it via normal means. Anyway - I thought that Europe is not cooling is pretty well known and barely needs support from a ref. But [2] would do if you want one William M. Connolley 21:46, 13 October 2006 (UTC)

[edit] Bryden measurements reported late 2005

I'm not sure if some of 71.123.23.59's changes ([3]) make too much use of text from the Guardian article Sea change: why global warming could leave Britain feeling the cold. Does someone who's familiar with Fair Use and Copyright have a view on this? --Leigh 06:33, 30 October 2006 (UTC)

Update - not completely sure I agree with William_M._Connolley's recent edit [4], but I suspect he knows rather more about this than I do. Just making note of what was on page here, and will revisit in a while once press has settled down.

On 27 October 2006, The Guardian reported that Bryden, presenting findings to a conference in Birmingham on rapid climate change, had uncovered evidence that part of the current came to a 10-day halt in November 2004.

Oceanographers were not previously aware that a 10-day halt in the deep flow of cold-water southwards in the western Atlantic was possible. Lloyd Keigwin at the Woods Hole Oceanographic Institution, in Massachusetts, described the temporary shutdown as 'the most abrupt change in the whole [climate] record'.

Prof. Bryden's group stunned climate researchers last year with data suggesting that the flow rate of the Atlantic circulation had dropped by about 6m tonnes of water a second from 1957 to 1998. The study prompted the UK's Natural Environment Research Council to set up an array of 16 submerged stations spread across the Atlantic, from Florida to north Africa, to measure flow rate and other variables at different depths. Data from these stations 'confirmed the slowdown in 1998 was not a "freak observation"'- although the current does seem to have picked up slightly since.[5][6][7][8]

Having talked to people who were there, this was just one minor issue out of a large conference. It isn't published; it isn't interpreted. Its probably just a natural fluctuation. It isn't what is sounds like (the entire circulation halting for 10 days, which would be impossible anyway). The RAPID array *wasn't* set up in response to Brydens paper, either William M.

[edit] Bias

This article says that the shutdown of thermohaline circulation would not affect the climate in Europe greatly, yet the majority of the references state otherwise. That was my general impression of the article; and the view of general unimportance of THC is not a commonly held one. -Iopq 12:01, 28 November 2006 (UTC)

The article doesn't say that. It does say that shutdown of the THC is considered unlikely. I'm not sure what you mean by "maj of refs" William M. Connolley 13:20, 28 November 2006 (UTC)

The article keeps changing pretty quickly. My comment is no longer valid as of this revision. -Iopq 12:07, 13 December 2006 (UTC)
