So now global warming can reach through time?

I can’t wait to see how the Church of Anthropogenic Global Warming rationalizes this:

Polar bears split from ancient bears more than 4 million years ago, suggests ancient DNA and the gene maps of multiple bears.

The polar bear genome finding reported in the Proceedings of the National Academy of Sciences journal contradicts earlier gene studies finding much more recent times for the ancestral split, within 600,000 years, between polar bears and grizzly bears, which can still mate and produce viable offspring.

What’s more, the report suggests that polar bear numbers have been on the decline for at least 500,000 years, driven by climate fluctuations.

Y’see, all that CO2 we’ve been dumping into the atmosphere is so powerful that it can cross time and space to induce climate change before it even existed!!!

You laugh, but I half-expect some cultist to seriously offer that explanation.

My take on the article is that natural, probably cyclic, climate change has expanded and contracted the polar bears’ range, sometimes reducing it considerably. In those times, more polar bears were forced to live on land and wound up mating with brown bears, a related species from which they split about 4-5 million years ago, but can still breed with. Hence, as we are in a gradual warming from the last ice age (and from the Little Ice Age that ended around 1850), their range is shrinking again, and there is some risk of them inter-breeding out of existence.

Perhaps, but, for now, their numbers seem to be rising.

Meanwhile the climate alarmists may need to get a new poster-animal.

    With a time cycle like that, who among us is going to be around long enough to actually be affected by or, for that matter, honestly give a crap about what happens that many years hence?

    Phineas, what you fail to mention is that Al Gore is also a time traveler. He has traveled back in time from his origins in 87,900 AD to warn us that the species known as ‘bulliticus dungi’ (today known as bull shit) is extinct in his time because of us.

    Who was here 500,000 years ago to know how many polar bears where here? The people that believe that are the same people that when when they see a sign on a park bench that says “Wet Paint Don’t Touch” they have to touch the bench to find out if the paint is really wet.

    Where I live we had glaciers a mile thick only 15,000 years ago. And we had polar bears and mastadons living here. By the time the glaciers had melted back to the north several thousand miles the mastadons died out but the polar bears survived. No one knows why the bears lived but the mastadons didn’t, but the bears are 3000 miles to the north of here now. When the glaciers come back, so will the polar bears. Too bad about the mastadons though.

    There are many scientists who believe we were responsible for the end of mastadons. If they could blame it on CO2 emissions they’d be very happy. Someday they’ll do it. Just watch.

    I know this is heresy but so what? If all of the bears and wolves on earth died out I wouldn’t shed a single tear.
