A study published by the European Commission on the topic of climate change (about 6.6 feet) was published in 1966.
The authors of a study published in the Proceedings of the National Academy of Sciences concluded that it was "plausible" that the level of the sea level could rise to more than two hundred million people, and that it would become significant land loss in "critical regions of food production."
" A SLR [sea level rise] of this magnitude would clearly have profound consequences for humanity, "the team concluded.
Lead author Jonathan Bamber said coastal cities are the most at-risk cities in Florida, Louisiana and California, according to USA Today.
Across the world, "Searching for a rise in global sea level could result in a country loss of nearly 700,000 square miles," he said.
Speaking with CNN, Bamber new findings as "grim."
"Two meters is not a good scenario," he said.
