Polar Bears Face "Tipping Point" Due to Climate Change

Edited on Tue May-25-10 05:47 AM by Stuart G

Source: BBC Earth News.

Climate change will trigger a dramatic and sudden decline in the number of polar bears, a new study has concluded.

The research is the first to directly model how changing climate will affect polar bear reproduction and survival.

Based on what is known of polar bear physiology, behaviour and ecology, it predicts pregnancy rates will fall and fewer bears will survive fasting during longer ice-free seasons.

These changes will happen suddenly as bears pass a 'tipping point'.

Details of the research are published in the journal Biological Conservation.

"What have they done to the earth?
What have they done to our fair sister?
Ravaged and plundered and ripped her and bit her
Stuck her with knives in the side of the dawn
And tied her with fences and dragged her down"

3. They're gone. I've long since written them off.

I give them another 50 years, at best.

5. Not that he will even see or read it, but I just sent this to Sen. Inhofe.

I hope that you don't mind.

Nothing upsets me more than climate deniers and he's about the biggest (blank)ing member of that club.
