Alex Bojanowski at Germany’s online concludes in a Der Spiegel reports here that “new study shows one thing: The influence of the oceans is greater than previously thought.” Does the SPIEGEL now understands that the climate change debate needs to focus on the ocean? That remains to be seen. Actually the PIEGEL report is about a new paper in NATURE, (23. Apet.2010) about a cooling in the North Atlantic from 1968-1972 that shall have significantly effected the Northern Hemisphere air temperatures, more details and comments HERE.
___Now it turns out that the theory is incomplete.
The most the SPIEGEL seem to grasps is rudimentary, as it is widely acknowledged that there had been a lasting global cooling over three decades from 1940 to the mid 1970s, and ocean cooling can happen quickly at any time and everywhere, a the mean ocean temperature is less than 4°C. What needs no to be acknowledged, that the start of the global cooling coincided with World War II, and the naval war during this period of time may have significantly shifted the air temperature trend in the North Atlantic and North Pacific as discussed in ppt (~ 3,5 MB each): HERE-Atlantic and HERE-Pacific, or see: http://climate-ocean.com/
However the SPIEGEL did a small step in the right direction, which will improve, hopefully.
