An investigation by the US Geological Service (USGS) has recently determined that as much as 30 percent of species would now rather spend their winters in Alaska, than in Mexico, for example. The situation is again a clear proof that global warming is happening very fast at the North Pole, and that action is required immediately to counteract these effects, the BBC News reports. The team believes that this trend is directly connected to the temperature shifts that were recorded in the Northern Pacific and the Bering Sea over the past couple of years. “This suggests that environmental conditions have changed for one of the northernmost wintering populations of geese,” USGS Alaska Science Center researcher David Ward shares. He is also the lead author of a new study detailing the find, which appear!
s in the latest issue of the respected scientific journal Arctic. Records of Pacific brant populations in the Arctic show that, before 1977, less than 3,000 individuals from the species remained in Alaska during the winter season. Since then, their numbers have increased to about 40,000 members, which is a sharp rise by any s...
