Scientists believed that roughly 2 billion people will be displaced by rising ocean levels by the year 2100.
“We’re going to have more people on less land and sooner that we think,” said lead author Charles Geisler, professor emeritus of development sociology at Cornell. “The future rise in global mean sea level probably won’t be gradual. Yet few policy makers are taking stock of the significant barriers to entry that coastal climate refugees, like other refugees, will encounter when they migrate to higher ground.”
By 2060 there are expected to be 1.4 billion climate change refugees. This will be the result of war, exhausted natural resources, desertification and land exhaustion.
In addition to this problem, low coastal zones across the globe also face stronger storm systems. These storm will force sea water further inland.
The prediction is that various governments will eventually be forced to start selling public lands for the purposes of human settlement.
These predictions can be prevented, however.
“The pressure is on us to contain greenhouse gas emissions at present levels. It’s the best ‘future proofing’ against climate change, sea level rise and the catastrophic consequences likely to play out on coasts, as well as inland in the future,” said Geisler.
