Greenland ice sheet shrinking faster than forecast, committed to irreversible sea level rise

Greenland Ice Sheet Depleting Faster Than Forecast, Irreversibly Committed to Sea Level Rise

A new report claims the Greenland ice sheet is so imbalanced with the Arctic climate that it can no longer maintain its current shape. In addition, it has been suggested that the ice sheet is irreversibly committed to shrinking 59,000 km, which is much larger than the area of ​​the Protected State of Denmark in Greenland. It has come to a disastrous conclusion that even if all greenhouse gas emissions were halted today, the current rate of ice loss would cause irreversible damage to the ice sheet.

according According to The Conversation, the loss of Greenland ice would raise global sea levels by at least 10.8 inches under current temperatures. This rise in sea level is reportedly higher than the current forecast model, even though it is reportedly an overly conservative estimate.

This new study reportedly changes the approach to forecasting sea level rise. It is said to be based on observation and glacial theory, rather than numerical models, which are reportedly ineffective in capturing the emerging processes driving Greenland’s ice loss.

For example, bio-albedo darkening is reportedly said to accelerate the melting and re-freezing effects of surface ice as well as surface ice. Such issues are reportedly not included in numerical models and can only be understood by drilling directly into the ice.

The Greenland ice sheet is a frozen reservoir that is more than 3 km thick and stores enough fresh water to raise global sea levels by 7.4 metres. According to the report, Greenland will lose at least 3.3 percent of its ice, more than 100 trillion metric tons, before it is able to re-establish equilibrium with the prevailing Arctic climate.
