Zombie ice is also known as dead or destroyed ice. Despite being part of the original ice sheet, fresh snow is not being accumulated on it.
Due to its continuous melting, there is a risk of rise in sea level. This is the result of pre-global warming.
According to a recent study, the melting of the Greenland ice sheet due to 'zombie ice' has resulted in a minimum of 27 cm in global sea level rise despite any climate action being adopted globally.
