Interesting subject, Kilimanjaro has never held much water in it's glaciers and that summer melting has never been much a source of water as such but I do agree with you, There is a 'natural' temperature rise peaking, just like there was a sustained global sub zero temperature age that peaked about the period 1645–1715, aptly named the 'mini ice-age' which will come back around again in its inevitable swing in another X amount of centuries, its 'mostly' propaganda about controlling us.
LOL
Where did that "5000" number in 1970 come from?
I love how simple minded science denial has become. Pick one number from some study, pick another number from a different study and start banging the drum.
Nobody is very certain about how many polar bears there are today. Maybe as many as 40,000. But the 5000 counted in 1970 was dead on accurate, I'm sure.
Like climate science, studying bears, especially polar bears is complicated. As described in this article:
https://www.canadiangeographic.ca/article/truth-about-polar-bears The bit I posted from the article (below) will probably be too long for a science denier to read. They get by on shorter sentences and memes. They already know the answer, so why should they go to the trouble to learn the details?
Where’s that bear?
There are 19 subpopulations of polar bears in the world, of which 13 can be found in Canada. The southern Beaufort Sea population, shared with Alaska, and the northern Beaufort Sea population, both of which are off the coasts of the Yukon and Northwest Territories, are either in or predicted to decline. A small population in Viscount Melville Sound, off the northern coasts of Victoria and Banks islands, could increase with changing sea ice conditions. M’Clintock Channel, off eastern Victoria Island, has seen polar bear numbers drop from about 900 to less than 300 over the past three decades. Lancaster Sound, off Baffin Island’s northern coast, is home to a declining population. The Gulf of Boothia population, off the northwestern end of Baffin Island, is stable. Foxe Basin is home to one of Canada’s largest polar bear populations, estimated at more than 2,500 animals in 2010. Norwegian Bay polar bears, south of Axel Heiberg Island and west of Ellesmere Island, are genetically different from all other polar bears worldwide, and their population status is unknown. Although the health of the western Hudson Bay population is the subject of debate, southern Hudson Bay, home to the most southerly polar bear population in the world, is relatively stable. Canada shares three of its populations with Greenland: the Baffin Bay and Kane Basin groups are both decreasing in numbers, while the Davis Strait population has increased in the past few decades but may now be in decline. The status of Greenland’s other two populations, in east Greenland and the Arctic Basin, is unknown. Russia is home to four populations of polar bears. The Barents Sea population, shared with Norway and Greenland, is healthy, while the status of the Kara Sea and Laptev Sea populations is unknown. The Chukchi Sea polar bears, shared with Alaska, could be in decline, though their current status is unclear.
Research in motion
Scientists study and count polar bears using two methods: capture-recapture and aerial survey. Capture-recapture, though dangerous because of the researchers’ proximity to the bear, helps determine the health and range of a population. Scientists take skin and blood samples, measure the bear’s height and weight and use ear tags to identify the country of capture. In an aerial survey, researchers in helicopters count bears along a predetermined line. This method can be tricky, as polar bears blend in well with the ice and bears in dens or behind ridges can be missed.
Changing environment
Warming temperatures are affecting the range of polar bear populations, shrinking their habitat and eventually, scientists fear, their numbers. While some northern bears may benefit from a more readily available diet, southern bears could find that food sources such as seal are more difficult to hunt and that human-bear encounters occur more frequently. Melting sea ice forces polar bears to fast for longer periods of time, impacting reproduction rates and the overall health of a population. Warming temperatures also increase human traffic, bringing pollution that impacts the health of both the bears and their prey.
Debating actual numbers is not very useful in predicting what will happen. There is no question that the habitat and food sources for polar bears is being disturbed. In the near future, polar bears will either have to live differently or die.
They might not go extinct. On this, I can agree with climate science deniers.
