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…
Researchers discover a new tool for reconstructing ancient sea ice
In a study published in Nature Communications, the researchers show that an organic molecule often found in high-latitude ocean sediments, known as tetra-unsaturated alkenone (C37:4), is produced by one or…
Claim: Scientists find the error source of a sea-ice model varies with the season
To address the issue of error source identification, Prof. Fei Zheng and his team from the Institute of Atmospheric Physics at the Chinese Academy of Sciences, evaluated the sea-ice simulations…
Claim: The climate changed rapidly alongside sea ice decline in the north
Researchers from the Niels Bohr Institute, University of Copenhagen have, in collaboration with Norwegian researchers in the ERC Synergy project, ICE2ICE, shown that abrupt climate change occurred as a result…
Rivers melt Arctic ice, warming air and ocean
A new study shows that increased heat from Arctic rivers is melting sea ice in the Arctic Ocean and warming the atmosphere.
First polar bear alert report for Churchill an astonishing seven weeks later than last year
The first report of the Polar Bear Alert Program in Churchill, Manitoba was released today (1 September), a full seven weeks later than last year due to many bears remaining…
Increasing Arctic freshwater is driven by climate change
New, first-of-its-kind research from the University of Colorado Boulder shows that climate change is driving increasing amounts of freshwater in the Arctic Ocean.
Shocker: Thick ice in Hudson Bay portends a good year for Polar Bears
From Polar Bear Science Sea ice more than 1.2m thick over Hudson Bay portends a good year for polar bears Posted on May 8, 2020 | The chart below shows what…

From Polar Bear Science Posted on March 24, 2020 | Winter sea ice maximum extent on March 5 was the highest since 2013 The most positive thing that US National…
New research first to relate Antarctic sea ice melt to weather change in tropics
Diminishing sea ice translates to warmer ocean, more rain, and stronger trade winds University of California – San Diego Arctic and Antarctic ice loss will account for about one-fifth of…
