10 Aug 2020 - Coral reefs face an uncertain future and may not recover naturally from human-caused climate change. Conserving them will require reducing greenhouse gas emissions, protecting key habitats and actively restoring reefs.
Shawna Foo: "Anyone who's tending a garden right now knows what extreme heat can do to plants. Heat is also a concern for an important form of underwater gardening: growing corals and "outplanting," or transplanting them to restore damaged reefs.
The goal of outplanting is to aid coral reefs' natural recovery process by growing new corals and moving them to the damaged areas. It's the same idea as replanting forests that have been heavily logged, or depleted farm fields that once were prairie grasslands.
I have studied how global stressors such as ocean warming and acidification affect marine invertebrates for more than a decade. In a recently published study, I worked with Gregory Asner to analyze the impacts of temperature on coral reef restoration projects. Our results showed that climate change has raised sea surface temperatures close to a point that will make it very hard for outplanted corals to survive."
