He led a team of researchers who meticulously tracked the weight and size of nearly 800 bears between 1992 and 2019.<\/p>\n<p>They found the polar giants to be in good shape, able to survive and to continue raising new cubs.<\/p>\n<figure class=\"embed embed--type-image is-image embed--float-none embed--size-medium\">\n<p>      <span class=\"img embed__content\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/assets2.cbsnewsstatic.com\/hub\/i\/r\/2026\/01\/29\/5a64479c-142d-4f31-9cac-50e4d4d22195\/thumbnail\/620x413\/7e3740acfaf05d364b92232d1d89a81c\/polar-bear-2225478762.jpg#\" alt=\"NORWAY-ENVIRONMENT-CLIMATE-RESEARCH-ANIMAL \" height=\"413\" width=\"620\" class=\" lazyload\" srcset=\"https:\/\/assets2.cbsnewsstatic.com\/hub\/i\/r\/2026\/01\/29\/5a64479c-142d-4f31-9cac-50e4d4d22195\/thumbnail\/620x413\/7e3740acfaf05d364b92232d1d89a81c\/polar-bear-2225478762.jpg 1x, https:\/\/assets3.cbsnewsstatic.com\/hub\/i\/r\/2026\/01\/29\/5a64479c-142d-4f31-9cac-50e4d4d22195\/thumbnail\/1240x826\/936dc3bfb2037c8ed85e54e16a9353e6\/polar-bear-2225478762.jpg 2x\" loading=\"lazy\"\/><\/span><figcaption class=\"embed__caption-container\">\n<p>                  <span class=\"embed__caption\">The head of the Polar Bear Program at the Norwegian Polar Institute (left), and Norwegian veterinarian Rolf Arne Olberg (right) measure a male polar bear in eastern Spitzbergen, in the Svalbard archipelago, in an April 17, 2025 file photo.<\/span><\/p>\n<p>                  <span class=\"embed__credit\"><\/p>\n<p>                OLIVIER MORIN\/AFP\/Getty<\/p>\n<p>                          <\/span><br \/>\n              <\/figcaption><\/figure>\n<p>&#8220;I was quite surprised,&#8221; Aars admitted, &#8220;because we have lost so much sea ice since I started.&#8221;<\/p>\n<p>For years scientists have raised the alarm that shrinking sea ice cover could put polar bears at risk, as they use the ice as a platform from which to hunt for seals.\u00a0<\/p>\n<p>&#8220;Some of us would predict that they should be in trouble already,&#8221; Aars said.\u00a0<\/p>\n<p>But what his team has found suggests the bears are adapting to smaller ice patches, and it may even be helping them hunt more efficiently as their prey, which also relies on the ice, is concentrated in smaller areas.<\/p>\n<p>&#8220;I think what this shows is they need less sea ice than we thought,&#8221; Aars told CBS News.<\/p>\n<p>His team&#8217;s research also found that the melting ice is pushing polar bears to get creative on land \u2014 where they&#8217;re increasingly feasting on other prey, such as reindeer and walruses.<\/p>\n<p>&#8220;Some of them would be on land as much as 90% of the time now, which is a lot,&#8221; he said.<\/p>\n<figure class=\"embed embed--type-image is-image embed--float-none embed--size-medium\">\n<p>      <span class=\"img embed__content\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/assets1.cbsnewsstatic.com\/hub\/i\/r\/2026\/01\/29\/ba6977b1-b71d-4f72-9aff-b07b1e981b2f\/thumbnail\/620x413\/a4108f1741eec2e2731a80d98e012247\/polar-bear-2227607773.jpg#\" alt=\"Turkish scientists carry out 5th National Arctic Scientific Research Expedition \" height=\"413\" width=\"620\" class=\" lazyload\" srcset=\"https:\/\/assets1.cbsnewsstatic.com\/hub\/i\/r\/2026\/01\/29\/ba6977b1-b71d-4f72-9aff-b07b1e981b2f\/thumbnail\/620x413\/a4108f1741eec2e2731a80d98e012247\/polar-bear-2227607773.jpg 1x, https:\/\/assets2.cbsnewsstatic.com\/hub\/i\/r\/2026\/01\/29\/ba6977b1-b71d-4f72-9aff-b07b1e981b2f\/thumbnail\/1240x826\/35f331345140c5b7dccb54af9899e947\/polar-bear-2227607773.jpg 2x\" loading=\"lazy\"\/><\/span><figcaption class=\"embed__caption-container\">\n<p>                  <span class=\"embed__caption\">A view of a polar bear during the 5th National Arctic Scientific Research Expedition in Svalbard, Norway, July 16, 2025.<\/span><\/p>\n<p>                  <span class=\"embed__credit\"><\/p>\n<p>                Sebnem Coskun\/Anadolu\/Getty<\/p>\n<p>                          <\/span><br \/>\n              <\/figcaption><\/figure>\n<p>While thriving bears is undeniably good news, Aars stressed that more research is needed to understand how polar bears in other parts of the Arctic are adapting to a warming climate.
