Columbia glacier melting accelerates in the Alaska
The Alaska has largest deposits of ice just next to Himalayas or Alps in the Europe. These giant glaciers also contribute massive amount of water to the ocean. But when you know that these glaciers are contributing more than usual, there is a problem. The new research on the glacier melting in the region has exposed increased water flow.
Geophysical Research Letters published the detailed study. The research journal is supported by the American Geophysical Union. The scientists discovered that around 75 billion ton water has been deposited by Alaskan glaciers to Pacific Ocean. This is going to alter water levels and salinity of water too. The salinity levels are important for breathing patterns of many marine creatures.
If the glaciers continue to melt on this scale, global ocean level will rise two-tenth millimeter per year. The rate has been similar for last two decades now. The Alaska state can be covered in one foot deep water with the collection of seven year water supply. In south-central Alaska hosts Columbia Glacier near Church Mountains at Kadin peak.
The shape of glacier is decided by barren rock marks behind. The rock is entirely visible now due to the climate change now. According to the data by United States Geological Survey, almost 50 percent of glacier has been dumped into sea. Polar Science Center at University of Washington further added that there is large amount of ice in the region but situation is worrying. The rates are higher as compared to other ice sources on the Earth.
