Can we still save corals in the face of global warming?

Can we still save corals in the face of global warming?

According to the latest Global Tipping Points Report from the University of Exeter, tropical coral reefs are dying on a massive scale.

➡️ Today, at +1.4°C, we have already crossed the critical threshold.

If we don’t reduce our emissions and reach +1.5°C, coral reefs will have a more than 99% chance of tipping, a point of no return for these essential ecosystems.

It is urgent to find more systemic and long-term solutions.

❌ There’s no point in transplanting doomed corals.

At Pure Ocean, we support scientific approaches that rethink reef restoration from the ground up:

💡 Reef Reborn: boosting coral reproduction with a lipid cocktail to increase larval survival rates. This also makes them more resilient to warming – UTS

🪶 Birds on Sticks: strengthening reefs by restoring the entire ecosystem, from corals to seabirds. More birds = more nutrients = healthier, more resilient corals – University of Essex

🧬 SymbioSwap: the first step in coral death is the loss of symbiotic algae due to heat. This project investigates whether warm-water algae could offer hope for the adaptation of temperate corals, such as those in the Mediterranean – University of Perpignan

🐠 Yaf Keru Impact: heat sensitivity is worsened by human pressures and destructive fishing practices. Yaf Keru Impact shows that by choosing more sustainable methods (no dynamite, no cyanide), reefs and the services they provide can come back to life – Planète Mer

🧭 It’s time to activate positive tipping points.

Every innovation, every project, every donation can help tip the balance in the right direction.

👉 Support the science that helps reefs adapt to climate change.

Birds On Sticks – with Hannah Epstein

Birds On Sticks - with Hannah Epstein

👥 Discover the brilliant minds behind our 2025 winners!

What if reintroducing seabirds helped restore coral reefs? In Polynesia, Hannah Epstein is installing floating nesting boxes to encourage their return. Their droppings, rich in nutrients, breathe new life into the reefs, plankton and fish.

🦜 In this video, she presents her Birds On Sticks project, winner of the 2025 prize.

BIG ANNOUNCEMENT 2025:
Discover our 6 winning projects!

Today is a great day for the ocean and for scientific research! We are delighted to unveil the winning projects from the 2025 Pure Ocean Call for Projects. These innovative initiatives will help protect the ocean, preserve marine biodiversity and build resilience in the face of climate change.

A round of applause for our 6 winners! 📣

👕 ALT-WASTE: map underwater textile pollution to combat it more effectively,

🌱AQUAMAP: develop silvo-fish farming to halt the erosion of mangroves, major reservoirs of blue carbon,

🦤 BIRDS ON STICKS: encourage the return of seabirds to fertilize coral reefs,

🐟 FISH ON THE MOVE: optimize the connection between marine protected areas to

boost biodiversity,

🦐 RIMIOMICS: demonstrate the toxicological impact of mining on abyssal ecosystems,

🪸 SYMBIOSWAP: test the exchange of symbiotic algae to make Mediterranean corals more resistant to climate change.

 

Why are this project important?

These projects pave the way for concrete, ambitious and nature-based solutions to the urgent challenges facing the ocean. Each of them has been selected by our scientific committee for its potential for innovation, its impact on practices and its contribution to ocean science.

Many thanks to our scientific committee Gilles Boeuf, Anna Zivian, Kartik Shanker, Abdelmalek Faraj, Flavia Lucena Fredou 🙏

🔬 Congratulations to the scientific teams and partners for their exceptional commitment. These projects are a big step towards a healthier ocean.

See you soon to find out more about these hopeful projects!
