Old Ice Sheets at Arctic Are Melting Rapidly, And May Lead to Sea Level Rise

Science

A massive transformation in climate, temperatures in the Arctic are getting warm. The sea ice present at the place is at its lowest level ever. The researchers are surprised by the rapidly melting ice in the Earth’s polar regions. According to the National Oceanic and Atmospheric Administration’s current year report, the Arctic is undergoing the most revolutionary changes in its lifetime. Although, those huge transformations may cause extreme weather conditions across the planet. A major conference related to Earth Sciences took place in the current week. Amid meeting, the new researches and reports revealed a hair-raising picture of warming in the Arctic and Antarctica regions.

Moreover, the melting sea ice in the Arctic depicts the effect of climate change. Researchers say it may be the catalyst for extreme environmental changes across the world. According to NOAA, the Arctic is getting warm twice than ever before, and it can be dangerous. Additionally, the event is melting some of the ancient ice slabs in the area. Emily Osborne, leading author of the study, says rest of the ice melts off, but the old ice doesn’t melt at all. Thus, the non-melted oldest ice keeps Arctic cold in the summer. Generally, old ice is thick in composition, but the researchers claim that it is not thicker now.

NASA scientists Catherine Walker and Alex Gardner said four glaciers at Vincennes Bay lost thick ice of nine feet formerly in 2008. In line with the Arctic report card, in March 1985, the ice older than four years shielded an area of 980,700 square miles. In current years March, it covered a minimal region of 130,000 square miles.  Robert Graham, a climate scientist at the Norwegian Polar Institute, says the melting of sea ice cannot directly rise sea-level. But warm temperature at the ocean in the Arctic could result in sea-level rise. On the other hand, Emily says she cannot say it’s too late and hopes that the situation will be under control.
