Despite concerns about future extinction, polar bear populations appear to have stabilised, and many in fact are growing.
For more than an hour I watch from a boat just offshore, transfixed and oblivious to the below-freezing temperatures, as the four-month-old twins gambol across the snow.
For years polar bears have been the poster boys of global warming - routinely reported to be threatened with extinction due to melting ice-packs and rising sea temperatures.
Indeed, when they were put on the US Endangered Species list in 2008, they were the first to be registered solely because of the perceived threat of global warming.
One prominent scientist said their numbers would be reduced by 70 per cent by 2050 while global warming proponents - including Al Gore and Sir David Attenborough - used emotive imagery to highlight their 'demise'.
Yet there is one small problem: many polar bear populations worldwide are now stable, if not increasing.
