Critters Away from The Global Warming Faster

WASHINGTON - The animals are fleeing the world of global warming in the north much faster than they have been less than a decade, according to new research.

About 2,000 species examined away from the equator with an average speed of over 15 meters per day, about one mile per year, according to new research published on Thursday in the journal Science that previous studies analyzed. Species are moving mountains to escape the heat, but more slowly, with an average of 4 per meter year.

Species - especially in the northern hemisphere and especially plant - moves intermittently, but over several decades, is on average about 8 inches an hour from Ecuador.



"Speed ​​is an important issue," the lead author of the study, said Chris Thomas of the University of York. "It's faster than we thought."

Included in the study was a study in 2003 found that species in the north at a speed of just over a third of a mile per year and up to a speed of 2 m per year. Camille Parmesan of the University of Texas, who led the study, said the new research makes sense, since the data was made ready in late 1990 and early 2000 were much warmer.

Federal data show weather of the last decade was the warmest, and in 2010 tied with 2005 for the warmest year. The gases from the combustion of fossil fuels, especially carbon dioxide, the heat accumulates in the atmosphere, global warming and climate change in different ways, depending on the overwhelming majority of scientists and the world, and scientific organizations.

There were the temperatures rose in the 2000s, the species studied at the fastest in the cooler areas, Parmesan said. He especially emphasized the city of copper butterfly in Europe and purple emperor butterfly in Sweden. Moths in Britain has moved over 135 miles in 21 years, said Thomas.

It is "an independent confirmation of the fact that the climate is changing," said Parmesan.

One of the fastest ways is the spider silometopus UK, says Thomas. In 25 years, the little spider its range of over 200 miles to the north, moved an average of 8 miles per year, he said.

The biologist Terry Root of Stanford University, who is not part of this study, but praised the intelligent and prudent points to a different species, the American pika, a creature like the rabbit Yellowstone National Park has been studying for more than a century. The pika has not been over 7800 meters in 1900, but were observed in 2004 at 9,500 meters, said.

For Thomas, it's something that every time he returns to his childhood home in southern England to realize. Biologist 51, saw the heron, a bird of the warmer climate to grow in the valley of the Cuckmere while. But now, he said, "All channels of the herons have. It was a strange sight."

Thomas traces the evolution of species and compared them as they move on the basis of changes in temperature. It was a perfect match in the region, showing that changes in temperature to explain what happens to the bugs and plants, Thomas said. The game was not as accurate with the Movement for the mountain and Thomas believes that because of the way was north of the court or were prevented from rising.

Thomas is the northernmost species live, the faster it moves from its base. This makes sense because in general the more northern regions nearer the equator than the heat ..

Conservation biologist Mike Dombeck, a former head of the U.S. Forest Service, said that the changes in the life of the species - is a problem for many endangered species - especially the movement in the mountains.

Thomas said he has studied is not a distant problem.

"It has affected wildlife across the planet," Thomas said in a telephone interview. "This is a problem that can occur in the lives of our children and grandchildren. If you look in your garden, you can be the effects of climate change already."
