Are Caribbean Islands Uninhabitable Due to Global Warming Fueled Hurricanes?

There is no way to know whether the series of hurricanes that barreled across the Atlantic in 2017 toward the islands of the Caribbean: a) foreshadow a trend, or b) were due to favorable conditions unique to the 2017 hurricane season. But it is indisputable that these storms have intensified unusually quickly and dropped huge amounts of rain. Global warming has contributed to Harvey, Irma, and Maria being particularly ferocious. Irma was the strongest Atlantic hurricane ever, and Hurricane Maria is the second fastest to reach Category 5. And in addition to Harvey, Irma, Jose and Maria in 2017, last year, Hurricane Matthew underwent a remarkable rapid intensification of 80 mph in 24 hours, intensifying from a Category 1 hurricane to a Category 5 hurricane.

The 2017 season has reversed the "so-called" hurricane drought of the past decade. But 2017 could very well turn out to be an outlier, and the next few years could return to the relative tranquility of the past decade. However, the ongoing warming of the waters of the Atlantic may have led to a tipping point being reached. Major hurricanes may hit the Caribbean islands with increasing frequency in the future. And if this year becomes the new normal, then many of the Caribbean islands are uninhabitable. Barbuda has already been evacuated, and unfortunately it may not be the last island that has to be evacuated. Time will tell whether Barbuda will be fully rebuilt.
