We all know that trees fight climate change by breathing in carbon dioxide and breathing out oxygen. But what about the ocean and coastal ecosystems -- how do they impact the climate crisis?
Have you read?
On this episode of Radio Davos we hear from an expert who has spent decades wading into Colombian swamps to extract soil samples from mangrove forests to learn more about carbon sequestration.
What's the World Economic Forum doing about the ocean?
Our ocean covers 70% of the world’s surface and accounts for 80% of the planet’s biodiversity. We can't have a healthy future without a healthy ocean - but it's more vulnerable than ever because of climate change and pollution.
Tackling the grave threats to our ocean means working with leaders across sectors, from business to government to academia.
The World Economic Forum, in collaboration with the World Resources Institute, convenes the Friends of Ocean Action, a coalition of leaders working together to protect the seas. From a programme with the Indonesian government to cut plastic waste entering the sea to a global plan to track illegal fishing, the Friends are pushing for new solutions.
Climate change is an inextricable part of the threat to our oceans, with rising temperatures and acidification disrupting fragile ecosystems. The Forum runs a number of initiatives to support the shift to a low-carbon economy, including hosting the Alliance of CEO Climate Leaders, who have cut emissions in their companies by 9%.

“In the case of mangroves, sediments can account for between 50 and 90% of the total carbon. That is the difference between mangroves and terrestrial forests,” says María Claudia Díazgranados Cadelo of Conservation International. “When mangroves are destroyed or degraded the carbon stocks that took millennia to accumulate and are located in these sediments, they are released in a matter of years, turning these important carbon sinks Into a significant carbon source.”
We also hear from a man who has been swimming in freezing arctic waters since 2003 to shine a spotlight on how global warming is already changing our world.
“When I did my first swim in the arctic, the water was 3 degrees centigrade. I went back there 12 years later and the water was no longer 3 degrees, it was 10 degrees centigrade,” says Lewis Pugh. “I've been in the ice for the last 18 years and I'm seeing the changes and I'm feeling them. Every single degree of water temperature which goes up or goes down has a huge difference.”
“From the ocean's perspective, everything is connected. Think of it as one bathtub. So, what's flowing off the Greenland ice sheet is causing a rising sea level in an atoll republic. If you're burning coal to get your electricity, you're contributing to the drowning of an age-old island culture.”
