If All The Ice Melted
If all the ice from both the north and south poles, as well as everything in between, were to melt, sea level would rise by 216 feet and causing major havoc on the world’s population. If carbon continues to be pumped into the atmosphere unabated, as climate change suggests, the ice will melt at a much faster rate than the 5,000 years it would typically take to melt all five million cubic miles of ice currently on the planet. Here is what North America would look like in that reality. National Geographic says:
The entire Atlantic seaboard would vanish, along with Florida and the Gulf Coast. In California, San Francisco’s hills would become a cluster of islands and the Central Valley a giant bay. The Gulf of California would stretch north past the latitude of San Diego – not that there’d be a San Diego.
