Big Panda Holds
Over the past century the temperatures have improved an average of one level Fahrenheit and scientists conclude that the Arctic has heated 10 times more. In Alaska the conditions have risen four to eight levels Fahrenheit within yesteryear half century, house of two-thirds of the world's polar carries possibly evoking the disappearance of these by 2050 as well as the fate of other creatures and people alike.
Five years ago when the polar snow caps had retreated 160 miles, twenty polar bears have been seen swimming 60 miles off shore within a crazy hurricane, but after only a couple of days, once the scientists returned, four of the carries had drowned. A change inside their behaviors, due to the thinning of beach ice that could decrease to half or disappear absolutely by the conclusion of the century many have identified the luck of the 4 polar bears.
Bears need ocean ice to hunt for seals. Closes regularly pop-up through breathing openings in the ice. From 1979 to 1981, 87% of باربری رشت تهران bears were available on ice slabs, but from 1992 to 2004, just 33% were on the ice. Throughout the summertime, as the snow melts off, the carries must come ashore and face food shortages before they've had enough time to store enough fat to last before next cold weather season.
Often they're observed ingesting useless carcasses. Fortunately for the carries, enzymes within their livers allow them consume also rotting beef making it unlikely a polar tolerate can be poisoned. As ringed closes become more scarce and their offspring figures greatly reduced, the holds have small choice but in the future on area more frequently and hunt caribou. As bears have less food to eat, and they slim down, females polar bears now evaluating around 55 pounds less than they did 30 years back, are also less likely to reproduce.
