21st Ocyober - Today's News: Berkely Earth Project Confirms AGW

Not quite the result some had been expecting as global warming confirmed by 'independent' study. So far the best the snti-science denail squad have been able to come up with is that the this annoucement has been made before the relevant papers have been peer reviewed.

I'm also interested in theor suggestion that:

...the global temperature correlates more closely with the state of the Atlantic Multidecadal Oscillation (AMO) index - a measure of sea surface temperature in the north Atlantic.

There are theories suggesting that the AMO index is in turn driven by fluctuations in the north Atlantic current commonly called the Gulf Stream.

The team suggests it is worth investigating whether the long-term AMO cycles, which are thought to last 65-70 years, may play a part in the temperature rise, fall and rise again seen during the 20th Century

Something to look at with regards the LIA and even full scale glaciations perhaps? Both of which seem to be centred on the North Atlantic region (and expand their influence subsequently to other parts of the world - the LIA, for example, appearing from some proxies to have started a couple of hundred years later in the S Hemisphere). What happens, I wonder, if the AMO fails in its warm phase at the same time that orbital parameters are more conduscive to milder N Hemisphere winters (more snowfall) and cooler summers (less snow melt)? Though equally we should consider that the former is an effect rather than a contributory cause. It may also have a bearing perhaps on Heinrich and D/O events? All good stuff!

Meanwhile, according to Bob Ward, Lord Lawson's Global Warming Policy Foundation is spreading errors.
