Populatia globala de ursi polari a ajuns la numarul cel mai mare din ultimii 50 de ani. Global polar bear populations are at a fifty-year record high.
Global polar bear populations are at a fifty-year record high.
Yet the International Union for the Conservation of Nature (IUCN) has just released a study suggesting that they are doomed.
Which version of events should we believe?
Well that all depends on where you prefer to place your trust: on reality or on computer models concocted by activists who desperately want the polar bear to retain its status as the ursine victim of the man-made global warming apocalypse.
If you prefer to go with reality, here’s the good news from Susan Crockford, who puts the global polar bear population at a very healthy 26,000.
This would mean, she has noted before, that the population has increased by around 4,200 since 2001.
Ce spun cei care seamănă panica Încălzirii Globale? Culmea ei recunosc cifra actuala de 26.000 deci omplicit și creșterea de 4.200 din 2001? Creștere care reprezintă peste 16% din cei 26.000 de ursi polari existenti astazi.
Polar bear populations could plummet by 30% in next few decades due to climate change, report finds
Habitat destruction means there is a 'high probability' that global polar bear populations will drop by around 8,000 in the next few decades

The planet's 26,000 remaining polar bears could see their population decline by 30 per cent in the coming decades due to global warming and the continued melting of arctic sea ice.
According to a report by the International Union for the Conservation of Nature (IUCN), one of the world's most influential conservationist groups, global warming is now the single biggest threat to the long-term surival of the polar bear as a species.
Greenpeace activists install giant polar bear outside Shell's London Polar bears live, breed and hunt on sea ice, but it's disappearing even faster than predicted.
The IUCN says Arctic sea ice has been retreating at a rate of 14 per cent per decade, from 1979 to 2011.
The longer the ice disappears for in the summer months, the longer the bears have to go without food. These extended fasts can cause reproductive problems and even starvation in some places.
According to projections, some parts of the Arctic could be ice-free for up to five months of the year by the middle of the century.
As a result of this constantly retreating ice, the IUCN says there is a "high probability" that the global polar bear population will decline by more than 30 per cent over the next 35 to 40 years, with global bear numbers dropping by almost 8,000.
Not only is retreating sea ice a problem in itself, but the decline of the polar bear, as an apex predator, could have major knock-on effects on the whole arctic ecosystem.
Fortunately for the polar bears, there are plans to help them. The Circumpolar Action Plan is a conservation strategy for the species that has been agreed to by the five states in which polar bears live - Norway, Canada, Greenland, Russia and the US.
