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 […]

By John PlattMay 24, 2010 02:03 PM An extremely rare “grolar bear”–a polar bear/grizzly bear hybrid–was shot and killed by an Inuit hunter in Canada’s Northwest Territories last month. Global warming has reportedly been driving grizzly bears (Ursus arctos horribilis) further north in search of food, bringing them into polar bear (U. maritimus) territory. […]
The balance of biodiversity within North American small-mammal communities is so out of whack from the last episode of global warming about 12,000 years ago that the current climate change could push them past a tipping point, with repercussions up and down the food chain, say Stanford biologists. The evidence lies in fossils spanning the […]
Christmas Bird Count (CBC) show that the warmer winters in recent decades have played an important role in shifting winter bird ranges to the north. CBC data from the mid-1960s through 2006 show that 170 (56%) of the 305 most widespread, regularly occurring species have shifted their ranges to the north, whereas only 71 species […]
