A new study dismissed all the early predictions of melting ice sheets of the Greenland. It demonstrates that previously scientists underestimated the ratio of the melting ice sheets. These ice sheets would probably cover double of its current land till 2060.
The melting ice sheets of Greenland plays a vital role in the elevation of sea level. The ignored impact of global warming can considerably increase the proportion of melting ice sheets.
NASA observed changes in the huge Ice Sheets of Greenland in the last five years. Recently, experts accumulated data from NASA and released a comprehensive image of the alteration in ice sheets.
The picture reveals the entire process through which ice sheets moves towards the sea. It provides significant information regarding the melting of water beneath the snow surface.
The chief goal of the study is to offer information which can help scientists in making an exact prediction of the melting of Greenland ice sheets. The outcome of the study shows that the melting of all the ice sheets can increase the level of oceans up to 6 meters. Such an increase would certainly cause a great harm to the coastal communities. Currently, the ice sheets of Greenland are 1.7 million square kilometer wide.
As per the early predictions, these melted ice sheets of Greenland mount up the sea level up to 22 centimeters till 2100. However, the new study completely rejected all these assumptions.
Dr. Amber Leeson, a researcher of University of Leeds’ School of Earth and environment informs that super glacial lake can boost up the present speed at which ice sheets melts. The new report uncovers that the region of Greenland would be double in the future.
The report is explained in detail in the Journal Proceedings of the National
