Hello, I'm Nula McAverine on the BBC World Service and this is BBC OS,

Conversations on the Climate Changing Seas.

We bring people together to hear how sea level rise is affecting islands in the Caribbean,

the Pacific, and the Atlantic Ocean, and also how changes in water temperatures

are disrupting fish economies in South Africa and the United States.

Some of the species that we used to see in the wintertime aren't coming as far

south as they used to, mainly spiny dog sharks, and generally they would be here in the winter time

for five, six months sometimes, and now we barely see them for maybe a month or two.

In the run-up to the United Nations Climate Change Conference, which you may have heard

referred to as COP26, we're continuing to spend time thinking about the global climate.

This time we're focusing on sea level rise.

A warmer climate leads to increased melting of glaciers and ice sheets,

and as a result, rising sea levels, which also increase coastal erosion.

In August, a report from the Intergovernmental Panel on Climate Change, or IPCC,

warned that although halting carbon emissions could stop warming, sea levels would continue to rise,

and even in a best-case scenario, islands and coastal communities would be at risk of flooding

and destruction. We'll hear from the former president of the Marshall Islands shortly,

but we'll begin by hearing from people who are from islands in the Caribbean and the US.

Marlon is speaking to us from Panama City, but is from the Florida Keys.

Denet runs a restaurant in Jamaica on the beach, and Nick is in new providence in the Bahamas.

We have about 700 islands spread across about 100,000 square miles, and none of our islands are really

particularly high above sea level. In fact, 80% of them are about a meter or less above the
