The Marine Mammal Protection Act of 1972 limited hunting, so with limiting hunting it's obvious that populations would have grown. Of course, that's only 36 years so let's go back further.
"In the 1950s the polar bear population up north was estimated at 5,000. Today it's 20- to 25,000, a number that has either held steady over the last 20 years or has risen slightly. In Canada, the manager of wildlife resources for the Nunavut territory of Canada has found that the population there has increased by 25 percent." - Dr. Andrew Derocher, Univ or Alberta
The above gets me in the 58 year range, which is technically 50-100 years. I can't find any data concerning populations prior, tho I'm sure it's somewhere.
Further, since you don't like Taylor:
“Polar bears, for example, survived several episodes of much warmer climate over the last 10,000 years than exists today. There is no evidence to suggest that the polar bear or its food supply is in danger of disappearing entirely with increased Arctic warming, regardless of the dire fairy-tale scenarios predicted by computer models.” - Evolutionary Biologist and Paleozoologist Dr. Susan Crockford of University of Victoria in Canada has published a number of papers in peer-reviewed academic journals
“We have this specimen that confirms the polar bear was a morphologically distinct species at least 100,000 years ago, and this basically means that the polar bear has already survived one interglacial period. This is telling us that despite the on-going warming in the Arctic today, maybe we don't have to be quite so worried about the polar bear.” - Award-winning quaternary geologist Dr. Olafur Ingolfsson, a professor from the University of Iceland, has conducted extensive expeditions and field research in both the Arctic and Antarctic
“We don’t know what the future ice conditions will be, as there is apparently considerable uncertainty in the sea ice models regarding the timing and extent of sea ice loss. Also, polar bear populations are generally healthy and have increased worldwide over the last few decades,” - Biologist Dr. Matthew Cronin, a research professor at the School of Natural Resources and Agricultural Sciences at the University of Alaska Fairbanks
“I think climate change is happening, but as far as the polar bear disappearing is concerned, I have never been more convinced that this is just scaremongering. People are deliberately seeking out skinny bears and filming them to show they are dying out. That’s not right,” - Naturalist Nigel Marven is a trained zoologist, botanist, and a UK wildlife documentary maker who spent three months studying and filming polar bears in Canada's arctic in 2007.
“In warmer regions it takes far less effort to ensure survival. How did the polar bear survive the last warm period? … Look at the polar bear’s close relative, the brown bear. It is found across a broad geographic region, ranging from Europe across the Near East and North Asia, to Canada and the United States. Whether bears survive will depend on human beings, not the climate.” - Biologist Josef Reichholf, who heads the Vertebrates Department at the National Zoological Collection in Munich
“I tell you there are as many bears here now as there were when I was a kid. Churchill [in Northern Canada] is full of these scientists going on about vanishing bears and thinner bears. They come here preaching doom, but I question whether some of them really have the bears’ best interests at heart.” - Polar bear expert Dennis Compayre, formerly of the conservation group Polar Bears International, has studied the bears for almost 30 years in their natural habitat
“Why scare the families of the world with tales that polar bears are heading for extinction when there is good evidence that there are now twice as many of these iconic animals, most doing well in the Arctic than there were 20 years ago?” - Botanist Dr. David Bellamy, a famed UK environmental campaigner, former lecturer at Durham University, and host of a popular UK TV series on wildlife
