No, global warming is not responsible for polar bears and grizzlies cross-breeding: they've been doing the dirty for a long, long time.
One of the many damaging effects of climate change put forward by scientists is that shrinking habitats are causing polar and grizzly bears to mate more.
This hybridisation could dilute polar bears' DNA which will further drive down the animals' already dwindling numbers, experts suggest.
But a new study reveals that this inter-breeding is natural and is in fact not a consequence of global warming.
Such hybrids among bears are not as rare as we have hitherto assumed,' said study lead author Professor Dr Axel Janke of the Senckenberg Biodiversity and Climate Research Center in Frankfurt.
It had previously been assumed climate change causes grizzlies or 'brown bears' to invade northern regions while polar bears are pushed onto the sea ice later than usual.
The new results show however that an abundant flow of genes among different bear species occurred plenty of times in the past.
Just yesterday we learned that the water flowing over the Antarctic ice shelf was a phenomenon that's been occurring for thousands of years, not a few decades, as the warmest "scientists" have told us; tomorrow will we see the "severe weather" fraud debunked?
As I keep saying, if global warming is actually real and capable of scientific proof, why do its advocates keep lying about it?
