Now we have actual proof that Greenland’s ice sheet is melting. Data taken from a NASA satellite shows that the melting of the ice has accelerated since 2004 and is melting at a rate of about 57 cubic miles per year. If Greenland’s ice sheet disappears sea levels will rise by 21 feet. I don’t know if many people have noticed this peculiar thing about our planet, but we have major bodies of ice one both ends of Earth (like the North and South Pole a.k.a Antarctica). They play a very important role in the how the Earth rotates and gravitational pull, yada yada yada. Greenland’s ice melting can cause big changes in the Earth’s gravity.
"Acceleration of mass loss over Greenland, if confirmed, would be consistent with proposed increased global warming in recent years," Dr. Jianli Chen and colleagues.
