| Weathernews Says Ice in Arctic Region Reaches 3rd Lowest Following 1978, 2009 |

Tokyo, Oct 6, 2009 (JCN) - The Global Ice Center at Weathernews, Inc. has announced that both the North Western (via Canada) and the North Eastern (via Russia) routes have not opened this summer.
According to the Global Ice Center's analysis, in 2009 the sea ice extent reached a minimum in early September. This was recorded to be the third lowest extent since 1978.
The lowest sea ice extent was recorded in 2007, these extreme minimums witnessed in recent years have been suggested to be a result of the global warming effect.
Sea ice extent in the Northern hemisphere has now started to increase meaning that there is no expectation that the Arctic routes will open in 2009. Although at present (29th September) the North Eastern route remains predominantly open for navigation purposes.
Temperatures within the Arctic region this summer were generally higher, and sea ice extent was lower than the thirty-year average. Within the North Eastern route temperatures were generally below recent years, and within the North Western route temperatures were above recent years average.
This trend in temperature patterns has shown agreement with a statistical trend describing temperatures in the Arctic during an El Nino year.
However, pressure patterns this summer were not like the pattern seen in 2007 in which winds effectively supported the migration of sea ice towards the North Atlantic. This is the one of the possible reason that the routes were not open this summer.
The Global Ice Center at Weathrenews, Inc. predicts sea ice extent with the use of their original prediction model named the I-SEE-ENGINE. It is known that surface winds, and currents affect sea ice migration, through the use of this model the Global Ice Center is able to examine ice movement and determine possible future routes.
These results are available at http://weathernews.com/GIC/. Although the Global Ice Centre has now finished monitoring sea ice melting within the Arctic region for the summer of 2009, it is still committed to monitoring sea ice around the world. At present the Global Ice Center is currently monitoring the Okhotsk Sea, which is now the focus for the Sakhalin 2 liquid natural gas project.
Weathernews Inc.is the world's largest private weather service company headquartered in Japan. It is the only global weather content maker that employs over 600 staff,including more than 200 meteorologists, in offices in 32 cities in 16 countries and regions.
