Professor Lars Kaleschke from the KlimaCampus Hamburg (Institute of Physical Oceanograph) reported that - while the data at the beginning of the summer were still within the 15-year mean - the past two weeks have shown a distinct reduction in Arctic sea ice. Already one month before the expected minimum, the ice coverage is approaching the value for 2007. Last September, the lowest coverage in the past 35 years was observed, i.e. since the first satellite observations began in 1972.
The results of Kaleschke are among the most important findings of the current Sea Ice Outlook-Report which is currently in publication. In this international project, noted climate research institutes compare their respective prognoses in order to test the reliability of the different methods.
