Greenland Ice Sheet Passes Point of No Return

The effects of climate change have become more visible in recent years. According to a team of researchers, Greenland’s ice sheet, which has been affected by severe melting, has passed the point of no return, and it will not be able to make a recovery.

More than four decades of monthly satellite reports on more than 200 large glaciers have been analyzed by the team.  The ice which is being released into the ocean has surpassed the amount of ice that is forming on the surface of the ice sheet by a significant amount.

Melting fast

If all the ice present in the Greenland ice sheet melts, the level of the will grow by 7 meters (or 23 feet) by the start of the next millennia. Massive floods would take place, destroying coastal cities that are spread across the world.

Current data infers that in the following 80 years, molten ice from Greenland’s ice sheet would boost the level of the sea by 6.9 centimeters (or 2.75 inches. The current glacial retreat has forced the ice sheet to enter a continuous state of loss, even if the climate would become stable or cooler.

Points of no return

The rate at which the ice sheet melts has increased constantly since 1990. In the past, the ice sheet enjoyed a 50/50 chance of losing or gaining mass every year, but the situation has changed radically, and now it can gain mass only once every 100 years.

Melting fuels a chain reaction as the liquid water which accumulates across the ice sheet will amplify the heat received from the Sun. However, scientists argue that the use of renewable energy and a global reduction in logging and mining could allow us to avoid other points of no return before it is too late and to prevent the appearance of even more dire consequences.
