Late Freeze-Up For W. Hudson Bay Polar Bears At Odds With Ice Conditions Elsewhere
There was so little ice on the west shore of Hudson Bay yesterday it is barely visible on the NSIDC global chart yet there was abundant ice in the Chukchi…
Chukchi Sea ice that didn’t melt this summer is now 2+m thick between Wrangel Island and the shore
Thick multiyear ice between Wrangel Island and the shore is now more than 2m thick, potentially impacting fall feeding for bears that routinely summer on Wrangel or the north coast of Chukotka.
Most Chukchi Sea ice in 20 years means no walrus feasts for polar bears at famous Russian cliffs
After years of hype, including documentary over-reach by David Attenborough and his collaborators at WWF and Netflix, there has been relatively abundant ice in the Chukchi Sea this summer, particulary along the Russian coast and…
Part 2: How Sea Ice Modulates Ventilation of Stored Ocean Heat and Warms the Arctic
Examines the three major factors affecting sea ice extent, ventilation of subsurface heat and Arctic temperatures and explains why warming air due to a cooling ventilating Arctic ocean should never…
Alaska polar bear researchers claim poor sea ice limited spring field work in 2021 more than 2019
The reporter tries to paint a picture of polar bears suffering harm from these recent conditions but in fact there is no published data from the Southern Beaufort after 2016,…
Sea ice growth after the summer minimum begins in the Canadian Arctic Archipelago
The Arctic sea ice minimum was declared to have been reached on 16 September this year (4.72 mkm2), breaking no records.
How do higher waves cause more ice clouds? Researchers claim expedition into arctic sea explains
Scientists explain the peculiar interplay that exists between sea-ice decline, wave height, and ice cloud formation over the Arctic
Still waiting for two thirds of polar bears worldwide to disappear due to lack of summer sea ice
The experts failed to account for the fact that less summer ice means more primary productivity and therefore, more food for seals and therefore, more food for bears (Coupel and Devred 2019;…
Stalled: September Arctic Sea Remains Surprisingly Stable Over Past Decade, “Long Way From Predicted “Ice Free”
This year’s Arctic sea ice minimum reaches third highest level in a decade, latest data show.
Polar bear habitat update for end July 2021 compared to previous years
I don’t see a looming sea ice catastrophe for 2021, do you see a looming sea ice catastrophe?
Western Hudson Bay polar bears: still some out on the sea ice, some causing trouble
As of Monday (19 July), more polar bears had come ashore near Churchill and on the shores of Wakusp National Park but some are still out on the bay. The…
As much Beaufort Sea polar bear habitat at mid-July 2021 as there was in 1982
Beaufort Sea ice coverage is about average for this time of year, again failing to decline in lock-step with other Arctic regions. Will there be lots of fat bears onshore…
Polar bear habitat update and the progress of breakup on Hudson Bay
From Polar Bear Science Posted on June 17, 2021 At mid-month, there is still an abundance of thick first year ice over much of Hudson Bay, suggesting that – yet again…
Landmark study casts doubt on controversial theory linking melting Arctic to severe winter weather
Every time severe winter weather strikes the United States or Europe, reporters are fond of saying that global warming may be to blame. The paradox goes like this: As Arctic…
Earth Day 2021: celebrate abundant sea ice habitat for polar bear feeding and mating
Late April is the height of the most important polar bear feeding and mating season and there is abundant sea ice habitat across the Arctic for doing both.
Southeast Greenland Sea Surface Temperature 1° – 2°C Warmer In 1940 Than Today, New Study Shows
Today some scientists like claiming the present is warmer than at any time in the past 1000 years and suggest the Greenland ice sheets are rapidly melting. But the results…
Polar bear sea ice habitat highs and lows in early February
Sea ice across the Arctic in the first week of February is a mix of highs and lows. Bering Sea is back up to almost normal coverage, as is the…
Unexpected ice
But observations show that ice extent in the Arctic has shrunk faster than models predicted, and in the Antarctic it has been growing slightly. Researchers are looking much closer at…
Sea Ice Slows Ships In North China Ports
Chinese ports and marine safety authorities are on high alert as an expansion of sea ice makes it tougher for ships to berth and discharge at key energy product import…
Polar bears can come ashore any time of year and cause trouble: a timely reminder
If you thought polar bears were only a danger to people in summer when sea ice is low, think again. Bears do occasionally come ashore early to mid-winter looking for…
Nares Strait Ice Arches
Both 2007 and 2019 were identical in having no arches formed. Whilst 2017 and 2018 were comparable to 2008. It is not statistically possible to draw significance from such a…
More food for Polar Bears: Arctic report card 2020 highlights the huge benefit of less summer sea ice
As well as summarizing sea ice changes, NOAA’s 2020 Arctic Report Card features two reports that document the biggest advantage of much less summer sea ice than there was before…
