Cryosphere Now: Snow​


The most recent snow cover information is given below. They are generally 1-4 days old. Hover over a thumbnail to get the full image, description, and credits. Important: The products shown on the "Cryosphere Now" pages provide a variety of perspectives on the state of the cryosphere. They are for purposes of illustration and comparison and are not necessarily endorsed by GCW as "authoritative".


Northern Hemisphere Sea Ice extent

Total sea ice extent on the northern hemisphere during the past years, including climate mean; plus/minus 2 standard deviations. The ice extent values are calculated from the ice type data from the Ocean and Sea Ice, Satellite Application Facility (OSISAF), where areas with ice concentration higher than 15% are classified as ice.

The total area of sea ice is the sum of First Year Ice (FYI), Multi Year Ice (MYI) and the area of ambiguous ice types, from the OSISAF ice type product. The total sea ice extent can differ slightly from other sea ice extent estimates. Possible differences between this sea ice extent estimate and others are most likely caused by differences in algorithms and definitions.


Data set
The sea ice extent data is composed by a Climate Data Record (CDR, 1979-2015), an Interim CDR (ICDR, since 2015 with 16 days delay) and a daily product to cover the period between the ICDR and today. Clic here for a detailed explanation.

You can read technical and validation reports here.

looks to me as if sea ice is above the last five year average.
but you keep on waiting for that NOAA report.

DNA From 2 Million Years Ago Reveals Arctic Utopia That Was 50-65 Degrees Warmer​

Two-million-year old DNA from northern Greenland has pushed back the genetic record by 1 million years to a time when the Arctic region was 50-65 degrees warmer, and home to abundant wildlife - including mastodons, lemmings and geese, The Guardian reports.

According to researchers from the University of Cambridge and University of Coppenhagen, the northern peninsula of Greenland - which is now a polar desert - once contained boreal forests of popular and birch trees that were teeming with wildlife.
"A new chapter spanning 1m extra years of history has finally been opened and for the first time we can look directly at the DNA of a past ecosystem that far back in time," said the researchers, Prof. Eske Willerslev, adding "DNA can degrade quickly but we’ve shown that under the right circumstances, we can now go back further in time than anyone could have dared imagine."
Willerslev added that similar techniques could someday be used to uncover insights into the first humans and their ancestors.
Willerslev and colleagues worked for 16 years on the project, which resulted in the DNA of 41 samples found hidden in clay and quartz being sequenced and identified. The ancient DNA samples were found buried deep in the Kap København Formation, a sediment deposit almost 100 metres thick that built up over 20,000 years. The sediment, tucked in the mouth of a fjord in the Arctic Ocean in Greenland’s northernmost point, was eventually preserved in ice or permafrost and lay undisturbed by humans for 2m years.
Extracting and analysing the DNA was a painstaking process that involved piecing together tiny fragments of genetic material that first needed to be detached from clay and quartz sediment. It was only the advent of a new generation of DNA sequencing techniques that allowed the scientists to identify and piece together extremely small and damaged fragments of DNA, through referencing extensive libraries of DNA collected from present-day animals, plants and microorganisms. -The Guardian
Once they pieced together the fragments, a picture emerged of forests teeming with reindeer, rabbits, lemmings and mastodons - the latter of which have previously only been found in North and Central America.
No carnivores were found, most likely because they were fewer in number, however the researchers speculated that there were likely ancient sabre-toothed tigers, wolves or bears.
"We don’t know what was there, but probably something that ate mastodons and reindeers," said the authors, adding that it's encouraging that these species have been able to thrive so far north in a region that would have still been cast into darkness for much of the winter due to its location.
"The data suggests that more species can evolve and adapt to wildly varying temperatures than previously thought," said Dr Mikkel Pedersen, of the Lundbeck Foundation GeoGenetics Centre at the University of Copenhagen and co-first author.

Polar bears of SE Greenland get shorefast ice necessary to hunt seals
Published on December 21, 2022
Written by Dr Susan Crockford


polar-bears-1.jpg

The 234 or so polar bears inhabiting the SE tip of Greenland, said to be genetically and ecologically unique because they are “surviving without ice“, have been experiencing sea ice formation along the shoreline this month just like other bears across the Arctic.

Recall that shorefast ice formation attracts seals in the fall, which polar bears hunt successfully, and the following spring (April/May) provide a platform for ringed seals to give birth to their pups, which polar bears eat with gay abandon.

The photo above was taken by Kristin Laidre in March 2016: a bear this fat at the end of winter (i.e. before ringed seals are born in the spring) is living in productive habitat.

According to the paper, the land-bound fast ice that most ringed seals use to give birth and nurse their pups in spring (April-May) is still routinely available in SE Greenland (Laidre et al. 2022; McLaren 1958; Stirling and Oritsland 1995).
Here is what polar bear biologist Steve Amstrup (2003:592) has to say about the spring feeding:
“In some areas, predation on pups is extensive. Hammill and Smith (1991) estimated that polar bears annually kill up to 44 percent of new born seal pups if conditions are right.”
If this ice lasts only until May 2023, it would be 180 days of productive sea ice and a far cry from the mythical ‘100 days’ which models suggest is the threshold for polar bear demise (Molnár et al. 2010, 2020).
This is apparently why polar bears in this region are doing just as well as those living in NE Greenland: in other words, thriving despite the pessimistic prophesies of ‘experts’.

Mammoth Mountain Closes Because Of Too Much Snow​

Last year, Mammoth received about 223 inches of snowfall during winter. So far this season, 328 inches have fallen, surpassing last year's total by more than 100 inches with still a few months left in the season.

brrrrrrr

That's how weather works, the abnormally warm air in Europe displaced the cold air to North America.

Or they had the HARRP running full blast as they were trying to get Europe into the deep freeze too. Messed up their freezing the EU.
heya Three. don't bother schooling anyone, it doesn't take. those huge low pressure fronts parked off the west coast for weeks were very strange, and i did wonder if HAARP was maintaining their position. fwiw
just checked Europe's ski resorts and found but 6 or 7 resorts not officially reporting open.
granted some conditions were not great, but declaring most closed due to conditions is a bald faced lie.

in the northeast too, few resorts fully open
and the lakes aren't freezing, that's getting a lot more common
not to mention record lows with the antarctic sea ice
quite simply it's warming everywhere, the trend is suddenly looking more dramatic
Honda Snowblower Enthusiasts Forum on FB reporting no snow in the Eastern Maritime Provinces of Canada, while Tahoe/Truckee in the 'hills' is reportedly inundated with way too much snow, and Buffalo, as many are aware, got hit numerous times, despite being just to the SW of the Canadian Provinces that are without any snow on the ground at all..

Was a bit humorous reading the 'sad' reports from the Canajun owners of new snowblowers worth THOUSANDS of dollars, in the Maritimes, upset at having no snow, and the replies from some in Nevada and elsewhere, telling them to run them around their yards on the grass for practice, and to show off their new purchases to their neighbors.

Edit: We're supposedly in a 'rare' 3rd La Nina in a row in Alaska (like some sort of 'blue moon' phenomenon), and we had maybe several days of -39 to -40 f. as our coldest to date this winter, while 40 years ago here, a 'cold winter' potentially meant weeks of -35 to -65 f).

Our summers used to get notably hot (close to 100 f. back then between mid-June and mid to late July), and winters notably cold, with scant rain in the summers and scant snow in most winters in the Interior. That's all different now.

Our dew point is routinely causing havoc in the winters now, more so than ever before, with glaze on the roads even without traditional conditions that caused such.

We're now mid-way through January, one of our 2 coldest months re. averages, and we've been above zero in the day time to limited degree this last week. Now sitting at a tolerable -12 f. on our front porch mercury and glass.
