A new study and computer-generated model by Nature recently shed light on the reality of what might happen if humans fail to reduce greenhouse gas emissions by the year 2100. In 2013, it was thought that the sea-level would only rise 3 feet by 2100 , but new studies have shown that levels could increase to twice that amount within the same time span. This would mean cities like Miami, Hong Kong, and Mumbai could potentially end up underwater, completely changing the geography of those areas.
"Cities may start to drown much faster than expected because sea levels could rise much faster than expected—mostly thanks to the way that Antarctica could fall apart and melt," says Fast Company's article.
On a more hopeful note, the model suggests that there still is time to prevent this from happening if humans are able to drastically cut emissions soon.
