Climate change in the Caribbean – learning lessons from Irma and Maria

Increasingly unfamiliar and unpredictable weather events mean that business as usual is not an option for these islands to survive

As a Caribbean climate scientist, I am often asked to speak about how climate change affects small islands. In the aftermath of Hurricane Maria, one of two category five storms to batter the eastern Caribbean in just a week, three words resonate in my mind.

The first word is "unfamiliar". Scientific analysis shows that the climate of the Caribbean region is already changing in ways that seem to signal the emergence of a new climate regime. Irma and Maria fit this pattern all too well. At no point in the historical records dating back to the late 1800s have two category five storms made landfall in the small Caribbean island chain of the eastern Antilles in a single year.
