How much contributes this study on the \u201cstructure of recent Arctic warming\u201d to understanding the \u2018climatic revolution[1]<\/a>\u2019 during the first half of last Century?<\/p>\n

Rune G. Graversen et al.\u2019s article in the first 2008 issue of NATURE[2]<\/a>, got immediate attention world wide. The authors conclude: \u201cWe regress the Arctic temperature field on the atmospheric energy transport into the Arctic and find that, in the summer half-year, a significant proportion of the vertical structure of warming can be explained by changes in this variable. We conclude that changes in atmospheric heat transport may be an important cause of the recent Arctic temperature amplification.\u201d<\/p>\n

Remark: There is no clear sign of progress in Arctic research. Where is the \u201catmospheric energy transport into the Arctic\u201d generated?\u00a0 Already back in the year 1938 C.E.P. Brooks raised the same question: to account for the change in circulation<\/em>[3]<\/a>.\u00a0<\/em><\/p>\n

\"20070107_clip_image002[1]\"<\/a>Some understood this immediately as confirmation that nature is pushing the Arctic to the edge, too. The study confirms according Seth Borenstein (AP)[4]<\/a>\u00a0that \u201cThere\u2019s is a natural cause that may account for much of the warming\u201d. \u2018Climate Feedback\u2019[5]<\/a>\u00a0disagreed: Graversen conclusion only means: “Changes in the circulation in the atmosphere might have had a much larger effect than previously thought, but these changes may also have been induced by greenhouse gases”.<\/p>\n

Remark: Does the explanation explain anything?\u00a0\u00a0 This website could show that extreme warming could commence (e.g. 1918\/19), although during the winter period the Northern North Atlantic used to be widely sea ice covered. The ocean is what matters.<\/p>\n

Also World-Climate-Report (03\/Jan) remained sceptical by noting that: \u201cpointing to ongoing climate change in the Arctic and yelling \u2018fire!\u2019 or, in this case \u2018humans!\u2019 seems scientifically a bit premature.\u201d[6]<\/a><\/p>\n

QUESTION: In a WMO Study from 1997 V.F. Zakharov[7]<\/a>\u00a0asked very clear question concerning the Arctic Climate System: (1) Why are the maximum climate fluctuations confined to the Atlantic sector of the Arctic?\u201d (2) Why are these fluctuations pronounced, first of all, right here?\u201d (3) Should the Atlantic sector of the Arctic be considered as a centre of some kind, a source of climate changes over the Hemisphere?\u201d. When will they be answered?<\/p>\n

SUGGESTION: Enter this website via the ToC links in the left column, and consider yourself whether the Arctic would be much better understood if the impact of the ocean is given more attention. The complete investigation comprises ca. 40 pages text without graphs.<\/p>\n
