Ah, but we have melting ice caps right now with NO rise. Water is unique as it truly doesn’t “get wasted”, just recycled through natural processes. More here, less there over time and at times broken down back to oxygen and hydrogen, but still all here nevertheless.
We have nothing near what existed back then for ice - all of N.America, Europe, to the Urals had ice 2 miles thick; its was so much weight, the land in Finland is still rising.
The amount of ice that melted then caused the ocean to rise on average 400 feet. Today, if all ice, including the ice cubes in your freezer melted, sea level would rise less than 40 feet.
More here? It rains down on Earth in meteoric form. There’s lots of water in many asteroids. Other water vapor escapes through atmospheric evaporation and is lost into space.
Don't buy into the meltdown lies. While one pole is melting a little, the other is increasing ice cover. So-called scientists will say what they're PAID to say!
