Arctic ice cover in decline
One site I regularly visit is that of Alastair McDonald. He has a page
(based on a NOAA site) that allows a comparison between now and four/eight years ago, though other dates may be entered. This summer is showing a very marked decline since four years ago, with virtually no ice on the coasts of Siberia. Here is the page: http://www.abmcdonald.freeserve.co.uk/north.htm -- Mike Tullett - Coleraine 55.13°N 6.69°W posted 20/07/2007 09:12:11 GMT |

The decline is quite marked but there seems little difference in the maxima (Feb/Mar). This would seem to indicate that the ice is shallower. Tudor Hughes, Warlingham, Surrey. |

This would seem to indicate that the ice is shallower. I returned to this site again today and the melting in less than two weeks is amazing. You are quite right in suggesting the ice is thinner. The colours clearly indicate that. Anyone doubting the existence of GW will surely be convinced by this. -- Mike Tullett - Coleraine 55.13°N 6.69°W posted 31/07/2007 21:47:45 GMT |

My personal explanation for this is that it must be due to the position of the jet stream for most of this summer. Normally the jet would take Atlantic depressions up there when, as we all know, it has stayed south allowing a large pool of cold air to sit in the region much of this summer. |

The following site shows that the decline is occurring in maxima as well as minima. It's also accelerating. http://arctic.atmos.uiuc.edu/cryosph...rrent.anom.jpg -- Graham P Davis Bracknell, Berks., UK Send e-mails to "newsman" as mails to "newsboy" are ignored. |

Maybe that has been assisted by more northerlies (or fewer SWlies) east of Greenland, associated with the anomaly you refer to? grr why do I keep typing Artic when I mean Arctic:-) -- Mike Tullett - Coleraine 55.13°N 6.69°W posted 01/08/2007 09:26:11 GMT |
