Polar Bears Starving; Resort to Cannibalism

[Buffanator]

For all you people (nerd4hire 😉 ) who think global warming doesn't exist & polar bears aren't in any danger at all....

Polar Bears Starving


"That warming is going to spread to the lower latitudes, to the United States, and it's going to affect storm systems and storm tracks, the jet stream; that's going to affect crops and all sorts of things," Meier predicted.

So, just how much ice is disappearing?

Less than 30 years ago, there would still be 7 million square kilometers or 2.5 million square miles of ice left at the end of an Arctic summer. That's now dropped by almost 40 percent.

Yeah, Polar Bears are going to be extinct, because of us, nice eh?

I think if you read the topic on global warming, you will see that I have technically been arguing that it exists, etc. and its anphropogenic.

Gotta tell you though, the polar bear thing doesn't sit with me. Personally think its a way to play on peoples emotions. Cos who doesn't love polar bears.

I'm just not going to expend any effort looking into this. If somebody says polar bears is eating other polar bears, I is on board, and I say tuck in. Granted its said with a certain amount of sarcasm and a huge amount of skeptisism, but there ya go.

Don't know and don't care how many MILLIONS of species of other animals have died out before humans even existed.

Natural cycles, circle of life bull crap.

What about all them other aminals out there what they thought were extinct but are now seeing? all them sppoted leopards and what not?

There's nothing unusual about polar bear cannibalism. It's been happening for as long as men have been studying them, and surely before then as well.

Low food availability and accidents on the sea ice
may be the main sources of cub mortality (Uspenski and
Kistchinski, 1972; Larsen, 1986; Derocher and Stirling,
1996). Intraspecific predation, infanticide, and cannibal-ism
have been reported in polar bears (Belikov et al., 1977;
Hansson and Thomassen, 1983; Larsen, 1985; Lunn and
Stenhouse, 1985; Taylor et al., 1985). However, some of
the instances have followed human activities such as
harvest or immobilization (Taylor et al., 1985). Regard-less,
intraspecific predation has been suggested as a regu-lating
feature of ursid populations (e.g., McCullough,
1981; Young and Ruff, 1982; Larsen and Kjos-Hanssen,
1983; Stringham, 1983; Taylor et al., 1985).

Polar bears have survived warmer periods than this one. Recently a 110,000 year old jawbone was found.

"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," explained Professor Ingolfsson.

"This is telling us that despite the ongoing warming in the Arctic today, maybe we don't have to be quite so worried about the polar bear. That would be very encouraging."
