Melting glaciers alter Earth’s gravity

Melting glaciers can alter Earth’s gravity field, scientists have found, a discovery that is shedding light on when Greenland and Antarctica began heavily melting. Knowing the timing of this melting could help climate scientists make better estimates of the potential
