In The State of the Polar Report 2018 zoologist Susan J. In fact the World Wildlife Fund WWF estimates that there are only 22000 to 31000 polar bears left in the world.

At present the official IUCN Red List global population esti-mate for the polar bear 2015 is 2200031000 about 26000 but sur -.
Polar bear population 2020. Results of three new polar bear population surveys were published in 2020 and all were found to be either stable or increasing. Published today in Nature Climate Change Fasting Season Length Sets Temporal Limits for Global Polar Bear Persistence projects when polar bear populations in the Arctic will cross thresholds of food deprivation that lead to rapid declines in reproduction and survival. They assessed 13 of 19 polar bear populations or around 80 percent of the roughly 25000 bears remaining.
In the Gulf of Boothia the polar bear population is stable about 1525 bears as estimated in 2017. Southern Beaufort polar bear numbers were found to have been stable since 2010 not reduced as assumed and the official estimate remains about 907. 4 populations are in decline.
Declines in global polar bear populations have long been predicted as sea ice loss continues. Data from conservation groups and the government show that the polar bear population is roughly five times what it was in the 1950s and three or four times what it was in the 1970s when polar bears became protected under international treaty. In related findings In 2020 Russian authorities announced the first-ever aerial surveys of all four polar bear subpopulations Chukchi Laptev Kara and Barents Seas to be undertaken between 2021 and 2023 reads the report.
Beaufort polar bear population stable since 2010 not declining new report reveals A just-released report on the latest count for the Alaska portion of the Southern Beaufort subpopulation reveals that numbers have been stable since 2010 despite claims the population has continued to decline. As of 2020 the global polar bear population size is now almost 30000 up from about 26000 in 2015. Results of three new polar bear population surveys were published in 2020 and all were found to be either stable or increasing.
Posted on October 4 2020 Comments Off on S. The State of the Polar Report 2018 put the new global mid-point estimate of the polar bear population at more than 30000. Some are stable some seem to be increasing and some are decreasing due to various pressures.
Declines in global polar bear populations have long been predicted as sea ice. For several of these subpopulations the number of bears is unknown. Based on subpopulation estimates and presumed densities in areas where numbers are unknown as of 2015 the IUCNSSC PBSG estimates that there are approximately 2200031000 polar bears across the Arctic.
Global polar bear abundance best guess estimate is 39000 26000-58000 Posted on February 26 2020 Comments Off on Global polar bear abundance best guess estimate is 39000 26000-58000 This is a sticky post link to my March 2019 essay on polar bear numbers at 2018. In the Gulf of Boothia the polar bear population is stable about 1525 bears as estimated in 2017. Warning that if greenhouse gas emissions stay on their current trajectory all but a few polar bear populations in the Arctic will probably be gone by 2100.
Bears in Canadas Archipelago ecoregion were not assessed because it is hard to estimate future sea ice in the areas islands and channels according to The Guardian. Bozeman Montana July 20 2020 Polar Bears International and a team of scientists from leading universities report that for the first time scientists have answered the critical question of when the persistence of polar bear populations across the Arctic will be threatened due to sea ice loss from global warming. Polar Bear Specialist Group estimated the population at 26000 range 22000310008 but additional surveys published since then have brought the total to near 30000 and may arguably be as high as 390009 This is only a slight-to-moderate increase but it is far from the precipitous decline polar bear experts expected given.
In related findings In 2020 Russian authorities announced the first-ever aerial surveys of all four polar bear subpopulations Chukchi Laptev Kara and Barents Seas to be undertaken between 2021 and 2023 reads the report. These may show increases in polar bear numbers or they may show stable or even declining numbers but we wont know until we see the results. Status of the polar bear populations Updated 2019 with data from the IUCN Polar Bear Specialists Group.
Mon 20 Jul 2020 1100 EDT. Even accepting the lower figure the estimate is the highest since the polar bear became internationally protected in 1973. Southern Beaufort polar bear numbers were found to have been stable since 2010 not reduced as assumed and the official estimate remains about 907.
Crockford says updates to IUCN data put the new global mid-point estimate at more than 30000. Although most of the worlds 19 populations have returned to healthy numbers there are differences between them.
