Global warming now is a very popular topic all around the world. According scientists, it will eventually melt all the ice at the poles and on mountain tops, raising sea level by 216 feet.
The video below shows the world as it is now, with only one difference: All the ice on land has melted and drained into the sea, raising it and creating new shorelines for our continents and inland seas.
There are more than five million cubic miles of ice on Earth, and some scientists say it would take more than 5,000 years to melt it all. However, if we continue adding carbon to the atmosphere, we’ll very likely create an ice-free planet, with an average temperature of perhaps 80 degrees Fahrenheit instead of the current 58.
