Polar bears and grizzly bears can and do interbreed.

As the Arctic sea ice disappears polar bears cannot live as they used to, hunting on floe ice etc.

The only big stable population of bears is on the remnant thick ice off the CAA.

Polar bear populations are headed downwards towards extinction.

The present glacial/interglacial cycle of major ice ages has lasted for a million years. In all that time CO2 has been below 300ppm. CO2 is now over 420ppm and rising. We have likely seen the last major ice age.

If you don’t like abortions ignore them like you do school shootings.

Geez louise. Of course they hunt on ice floes. What do you think seals haul onto? Roll Eyes

So you have a reference for that? Grin

More hyperbole - not backed up by facts. Roll Eyes

And above it. Roll Eyes

Ah and yet you have no reference. Merely unsubstantiated assumptions. Roll Eyes

And yet you can't cite anything. Roll Eyes

"Fossil results indicate polar bears survived last global warming deglaciation in Siberian and Canadian refugia"

We have AGW and a MUCH higher level Of CO2 now than at any other time in the last million years or so.

Big ice floes that polar bears need to hunt seals are disappearing with the ice—while the volume of ice, as we have seen, is decreasing pretty steadily the extent or area is slightly increasing—the ice outside the CAA area is slush not solid ice.

Remember those wide error bars. Grin

And then of course CO2 lagged and still LAGS temperature. Wink

Again, unsupported by evidence. Why is that? Wink
