Climate change is affecting everything, though sometimes in bizarre manner. Sea ice expands in Antarctica in winter, while wooden area increases in Arctic
Climate change is affecting everything. From Arctic to Antarctic and from Hawaii to Hong Kong things are going from bad to worse. The climate change is not only making things worse for the inhabitants of these places, even the pressure of ice melting is expanding the sea ice. This is a new trend and scientists say this is a dangerous indeed.
A report says that this opposite scenario has been caused by the fact that ice that melts in the innermost part of the Antarctica comes to the top and then refreezes when exposed to the icy breeze on top of the water surface of the sea. Reports suggest that these opposite phenomenon have been observed in recent times and shows that though the ice may look like expanding, in fact opposite is the case. A latest report suggests that there is an expansion of around two percent in the ice compared to the year 1985. The report has been published by KNMI and is giving a jolt to scientists and policy planners across the world.
On the other hand another study suggests that in Arctic region, the greenery is increasing due to the fast melting of ice in the region. 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.”
There are more details coming out about these increased wooden area. “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.”
