are birds moving north global warming
That's the finding of a new study led by the U.S. Forest Service, which concludes that a few dozen tree species in the eastern U.S. are moving north at an unexpected rate, likely due to global warming. The report, from the UN's Intergovernmental Panel on Climate Change (IPCC), finds that many life-forms are moving north or into deeper waters to survive as their habitats shift. They're also being forced to change their behaviors. So news that some tree species may be headed north at an average clip of 62 miles (100 kilometers) a century may come as a surprise. At that rate, stands of yellow birch in the U.S., for example, may move well north of the Canadian border by the early 2100s. Enlarge Photo. This Is Just the Beginning. Protecting birds from climate change is a central pillar of Audubon’s mission. In the hands of the Audubon network around the country, this data will drive our conservation efforts now and into the future. For instance, many birds are nesting, breeding, and migrating earlier as spring arrives sooner than before. (Related: Ten U.S. Species Feeling Global Warming's Heat.) Evidence of climate change impacts is strongest and most comprehensive for natural systems, the report said. WASHINGTON — When it comes to global warming, the canary in the coal mine isn't a canary at all. It's a purple finch. As the temperature across the U.S. has gotten warmer, the purple finch has been spending its winters more than 400 miles farther north than it used to. And it's not alone. For other species, global warming may not be a major factor in the movements measured by Audubon at all. The wild turkey was second only to the purple finch in miles moved north — about 400. But it's likely due to efforts by hunters and state wildlife managers to boost its population. July 3, 2006. A survey of Scottish birds finds that global warming may be having an effect, with some once-common birds moving north. The Breeding Bird Survey by the British Trust for Ornithology found that seven species are in marked decline in Scotland, The Scotsman reports. Explore the Impacts. Audubon’s findings classify 314 species—nearly half of all North American birds—as severely threatened by global warming. Our interactive maps show how each of these at-risk birds’ potential ranges could expand, contract, or shift in both summer and winter as our climate changes. Global warming is the greatest threat to birds and other wild-. life in human history. The rate of global warming is already. impacting birds, their prey, and their habitat. Those impacts. will become more severe over the coming decades, leading. to the loss of one-quarter to one-third of all species on earth,
Yes, global warming may be having an effect, with some once-common birds moving north.
