Arctic Freeze Up This Winter Ties For Lowest On Record

  Maximum Ice Extent Ties Record Low Every winter, the Arctic ocean freezes and you can literally walk from Canada across the Pole to Russia (except in a few areas that rarely freeze). The stunning loss in Arctic ocean sea ice continues, and while the summer melt gets most of the attention, this winter the amount of Arctic ice was tied for the lowest on record. Here are the official …

The global sea temps. were the 11th warmest on record. What is really eye catching is the intense cold in Central and East Asia.

Arctic Ice Update-Another Record Low in January

Here is the release from the National Snow and Ice Data Center: Arctic sea ice extent averaged over January 2011 was 13.55 million square kilometers (5.23 million square miles). This was the lowest January ice extent recorded since satellite records began in 1979. It was 50,000 square kilometers (19,300 square miles) below the record low of 13.60 million square kilometers (5.25 million square miles), set in 2006, and 1.27 million …

NOAA/NSIDC: December Arctic Sea Ice Lowest on Record

The National Snow Ice Data Center (NSIDC) released the Arctic ice summary for December today. It’s the lowest on record at 12 million square km. This is 270,000 sq. km below the previous record. The highly negative phase of the North Atlantic Oscillation is likely a contributing factor here.  The negative NAO has drained much of the polar cold down into two main regions; Eastern N. America and Western Europe. …

NOAA: January-November 2010- Hottest On Record

The National Climate Data Center (NOAA) released the November temp. data today and also put the year in context. November was the second warmest on record with an average temp. of 1.24°F (.69C) above the 20th century average. Even more interesting is the fact that from Jan.- November the global temperature is the warmest on record. This is all the more surprising since we had a very quiet sun (long …

Arctic Sea Ice Reaches Second Lowest Level On Record

The melt season is just about over North of 60 and the NSIDC announced today that the surface ice  coverage is now the second lowest on record. Keep in mind that the more important figure to watch is the overall volume of sea ice. Those numbers continue to show a precipitous decline… Welcome to the new normal… UPDATE: The ice drop has accelerated over the past two days. Mark Serreze …

Northwest Passage Opens (4th consecutive year)

Meteorologist Jeff Masters has a lot more about it, but the NW Passage is now mainly free of ice and is navigable. You can see a cool 30 day animation of the melt here. It looks like the NE Passage from Europe to Alaska is almost free as well. Masters says this is the 4th consecutive year that the passage has opened. It’s also the 4th time in recorded history. …

Arctic Ocean Ice cover drops to 2nd lowest July level on Record.

The Arctic sea ice level dropped to the second lowest July levels on record last month. The data record goes back to about 1978. That’s when reliable satellite based measurements began. The lowest amount on record was on 16 September in 2007. Will we set an all time low record this year. Scientists at the National Snow and Ice Data Center in Colorado are thinking that we likely will not. …

Oldest Greenland Ice Core Recovered

I’ve just returned today from Greenland and am looking forward to seeing my first “night” in 10 days! The 14 countries that have supported the NEEM ice core project got their money’s worth this week. The two year project to drill an ice core through 2,500 meters of ice finally reached Greenland rock. Where Is It The NEEM site is at 8,300 feet on top of the ice sheet. I arrived …
