Hi
I've just been having a look at the Arctic SYNOP reports for 1200 UTC today and thought that they looked rather cold for this time of year – even up there. Have a look on my blog at the two climate charts for Cape Morris Jessup (04301) at the top of Greenland at around 83° N, one from last year and the other for this year. Other sites like Eureka (71917) at around 79°N are also sub-zero in stark contrast to last year. It’s probably late summer 2012 was so warm in the Arctic last year although I do think Winter has returned a little early to these parts. I do have some scattered pieces of temperature climatology for Cape Morris Jessup from the CRUTEM4 data set to compare with. I haven’t heard much mention about the thinning and disappearance of the sea ice recently and unfortunately don’t have the time to check and see if this isn't the record year at lot of people were expecting.

This year ranks as one of the heavier ice years compared to the previous half-dozen but is still lighter than earlier years. http://www.ijis.iarc.uaf.edu/seaice/...e_Extent_L.png -- Graham P Davis, Bracknell, Berks.

Bruce. Images on my blog: https://xmetman.wordpress.com The weather has been very stormy, with persistent low pressure over the Arctic basin and this has slowed melt this year. Would you point out who was expecting a record low? I don't think anyone did. I've been saying for a month that a record looked unlikely and it still does. Record summer lows always depend on the weather and the reduction in summer sea ice will not be linear over time because of this, but, as Graham rightly says, despite conditions heavily favouring more ice, this year's low will be far lower than most years in the satellite record. I'd expect the summer ice to be all but gone by the middle of this century. You can check ice extent/area on these sites: http://nsidc.org/arcticseaicenews/ http://www.ijis.iarc.uaf.edu/en/home/seaice_extent.htm http://arctic.atmos.uiuc.edu/cryosphere/ http://arctic-roos.org/observations/...tent-in-arctic It'll only take a minute for you to check now. NSIDC's last update and commentary is in the first link above. There's some information there that will inform your blog comments and it might be worth mentioning that many Arctic areas were anomalously warm before the start of July, with records being set for temperature in Alaska. It's just weather Bruce; worthwhile commenting on, but it's nothing more than unusual weather. Paul |

...

Bruce. ================================================= Like Graham, I do not know of anyone who was expecting a record melt this year. It took five years for the 2007 record melt to be broken, so it was always unlikely that last year's record melt would be broken this year. Lawrence has already pointed out that the temperatures north of 80N have been unususally low this summer, as is seen in this chart: https://sites.google.com/site/arcticseaicegraphs/ But despite Arctic air temperatures dropping below 0C, the sea ice is still retreating, and it will most likely continue to do so until the first week in September. If you don't want to spend too much time checking the state of the Arctic, then a glance at this this web page will give you all you need: https://sites.google.com/site/arcticseaicegraphs/ Cheers, Alastair. |

How odd all those prophecies that numerous AGW protagonists have made, with many being news grabbing predictions of an 'Ice Free 'arctic.. Yet here you are scratching your head like a dazed Alzheimer's sufferer.. It really is pathetic how apparently intelligent humans have fallen for this politically driven trash. Many here on this NG are also dishonest by nakiing out this is all now a surprise. |

It's the coldest measured temps since 1958 FFS and you act like you have the answer, it's all down to 'stormy weather' case closed as Inspector Clueless strikes again. |
