NASA revealed what Earth would look like if the oceans dried up
and formerly with NASA. Dr. O’Donoghue recreated the video at a much higher resolution, slowed down the animation to better see what the Earth looks like during the first 10’s of meters of draining and added a tracker to show how much water had been drained.
During the last glacial maximum , about 26,000 to 19,000 years ago, sea level was about 410 feet below its current level. The sea level was so much lower than it is today because a tremendous amount of the ocean’s water was locked away on top of continents and countries across the globe, from Antarctica to Greenland as well as northern North America and Europe.
Our ancestors migrated from continental Europe to the UK through land bridges, as well as from Alaska to the far eastern tip of Russia. Also, the land connecting North and South America was wider and thus easier to navigate between the two continents.
