What's is happening to the total amount of water on earth

Climate change is melting the polar ice caps and releasing green house gasses into the atmosphere. Because of this the Earth's sea levels are rising. The amount of liquid water is increasing.

Water is slowly disappearing into space; scientists predicted that 1/4 of earth's water has left over 4 billion years.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
