ENVIRONMENTGreenland Ice Sheets Rapidly Thaw Than Expected

The Greenland ice sheets are exceptionally melting faster than first thought.

According to the study published in the scientific journal “Nature”, that Greenland ice sheets melt increased rapidly in the past 20 years. Right now, it is thawing at a rate of 50% higher compared to small-scale levels and 30% beyond 20th-century levels. The ice sheets contain sufficient water to elevate global sea levels by 23 feet.

Woods Hole Oceanographic Institution associate scientist Sarah Das said, “What we were able to show is that the melting that Greenland is experiencing today is really unprecedented and off the charts in the longer-term context.”

Researchers drilled into the ice sheets to obtain ice core samples to determine the rate of ice melt. The sample was extracted from locations over than 6,000
feet above sea level providing scientists an opportunity to identify ice sheet melt over the past several hundred years.

Ice core samples were taken from  and a coastal site on the Nuussuaq Peninsula three years ago. With these samples, scientists were able to identify when did the ice melt and refreeze along with the frequency and sizably of the process through the years. They discovered that in recent years, there was a huge volume of melting process, water purification through the ice, and refreezing every winter.

According to the UN Intergovernmental Panel on Climate Change report in October, a caution has been given where civilization only has over a decade to hold back climate calamity. The message informed more concern for planet Earth, particularly for the millions of people residing close to the world’s oceans.

Rowan University assistant professor and co-author, Luke Trusel noted that when the atmosphere persists to become hot, melting will leave the warming behind and keep on accelerating.

The Greenland ice sheet melt is the only and biggest motivator of global sea level rise. Scientists conclude that it can flood coastal cities and communities in the years to come. Among the 10 largest cities in the world, eight are situated near the seaboards. Likewise, there are about 40% to 50% of the world’s population that lives along the shorelines susceptible to rising seas.
