This is a very scary news and doesn’t augur well for our world. Arctic sea ice volume is diminishing fast and greener Arctic is expected in coming decades
A new study predicted that the temperature of the Arctic region has increased so much so that it would be covered by greenery or plants in near future.
According to researchers from the American Museum of Natural History, the wooden area of arctic would probably increase as much as by 50 percent in the next few decades and will make it greener. The research published in the the journal Nature Climate Change, specifies that the Arctic would be covered by greenery by 2050 approximately. The researchers also revealed that this sudden greening would speed up the climate warming rate much more than previously expected.
Richard Pearson, lead author on the study and a research scientist at the American Museum of Natural History’s Center for Biodiversity and Conservation said, “Such widespread redistribution of Arctic vegetation would have impacts that reverberate through the global ecosystem.”
“These impacts would extend far beyond the Arctic region,” Pearson said. “For example, some species of birds seasonally migrate from lower latitudes and rely on finding particular polar habitats, such as open space for ground-nesting.”
The temperature in the Arctic is increasing at an alarming rate and this has led scientists to predict a model of future Arctic region where some of the significant plants may grow according to the climatic conditions.
Walt Meier, a research scientist at the National Snow and Ice Data Center in Boulder, Colo, said, “That entire region is largely covered by seasonal ice, not multiyear ice, and that’s a real different ice pack than what we used to have.”
The research included scientists from the American Museum of Natural History’s Center for Biodiversity and Conservation, Colgate University, Cornell University, the University of New York, AT&T Labs-Research and the Woods Hole Research Center who predicted that current results on climate scenarios could be for the 2050.
However, this study also predicts the global warming could possibly have an effect on every part of the world. “By incorporating observed relationships between plants and albedo, we show that vegetation distribution shifts will result in an overall positive feedback to climate that is likely to cause greater warming than has previously been predicted,” claimed co-author Scott Goetz, from the Woods Hole Research Center.
Retired Rear Adm. David Titley, an expert in Arctic climate policy, said during a press conference, “The amount of hard, thick ice has just collapsed. There are now just remnants of it,” said. “So far, we see no evidence that it’s coming back.”
