Polar bears can be saved by emissions cuts, study says
Cutting global greenhouse emissions might yet save the polar bear and its Arctic habitat, according to scientists in the US.Well that's a shocker! I had no idea the polar bear was in danger of extinction due to man made global warming. I'm still not convinced. Maybe a cute picture of a struggling polar bear will help change my mind?
It has been suggested that emissions of greenhouse gases have already put the Arctic ice cap and the polar bear on an irreversible path towards extinction.
But a new study suggests rapid emission cuts could help preserve ice cover to save the iconic bear.
Ahh. Here it is:
Trust BBC News to pull on the heartstrings rather than report the truth.
The arctic ice sheet is not disappearing, it is changing shape and thickness, just like it always does as part of natures cycle. To my knowledge, polar bears are not an endangered species, at least not as a result of global warming melting the ice caps.
A US Geological Survey team led by Dr Steven Amstrup predicted back in 2007 that two-thirds of the world's 22,000 polar bears would disappear by half way through the next century.
Dr Amstrup and colleagues now say that such dire forecasts might be avoided if industrial societies act quickly to cut emissions.
Time will tell. Trouble is, we won't be able to do detailed computer models of polar bear numbers or ice cap formations when we are all living in mud huts. We will be more likely to eat the bloody bears and use their skins for warmth.
