Some 'People' really need to take notice... On all of the Alaskan shows they have spoken about the lack of a 'True Winter' for 4yrs now...Yes it may-be just the Earth adjusting or something very different.... Towns are getting invaded by Polar Bears cause their 'natural. food supply is Diminishing in their natural habitat.. The 'Growler' Bear has come about cause Polar Bears have come into contact with Brown/Grizzly Bears... This has never happened before as their territories never met, till the diminishing Ice Packs . Even the residents of Alaska have spoken about their Food Supply rapidly disappearing due to this 'Phenomenon' ....
'Growler' Bear:

Not exactly - growlers had been noted for yonks, but only recently have DNA studies been applied to "growlers" and confirmed they were hybrids.
"Genetic analysis has revealed multiple instances of introgressive hybridization between bear species,[4][5][6] including introgression of polar bear DNA into brown bears during the Pleistocene"" The Pleistocene is the geological epoch which lasted from about 2,588,000 to 11,700 years ago, spanning the world's most recent period of repeated glaciations." So this is not something new.
As for invading towns, it was occurring more than 50 years ago as I mentioned - and there were very few towns in the Arctic back then. They were a nuisance at Churchill dump, and my son used to email local kids about it decades ago.
The polar bears never lived to any extent on the sea ice during winter. Because the reports we read are usually about winter sea ice extents, most people don't realise that summer sea ice has always been far less and not connected with the land. People think that the Arctic is covered with ice and snow all year, but I used to work along the northern Canadian coast (eg Bathurst Inlet) and there was only the occasional tiny iceberg (and occasional snow drifts a few tens of metres long in sheltered spots) in summer. Both grizzlies and polar bears occupied the same coastal land (I saw them 40 years ago, including grizzlies right to Coronation Gulf - one had to be wary). Reports of their decline was not substantiated when I last looked this up ten years ago - apparent decline in some areas related to possible migration and was offset by increased numbers in other areas.
I am convinced that climate change is real - I just get annoyed by the way that things always common are being claimed as new and unique. The Arctic IS definitely warming, winter (and the small amount of summer) sea ice IS decreasing (although not a lot for some years now). I suspect that rather than starving polar bears moving south for food, grizzlies may be finding it more hospitable further north.
We should be very concerned about climate change. It will no doubt ultimately significantly affect some of these species. But a polar bear perched on a bit of ice is nonsense evidence for it (do you think he has been sitting there until all the rest melted around him - a very slow process)? They do swim.
'Fake news" about climate change (usually generated by the media and tourists with cameras, not scientists) is simply fodder for "deniers" because such things are so easily disproven, then damaging some of the populations' belief in climate change. Scientists know it is warming, but because they collect abundant, reliable data on a regional scale.
