"The world’s oceans are being rapidly transformed as climate change
intensifies. Corals are bleaching, sea levels are rising, and seawater is
becoming more acidic – making life difficult for shellfish and reef-building
corals. All this and more is unfolding on our watch, with profound consequences
for marine ecosystems and the people who depend on them.
In response, scientists, governments and industries are trying to intervene.
People all over the world are experimenting with new ways to capture and store
more carbon dioxide, or make up for damage already done.
Ocean-based climate actions include breeding more heat-tolerant corals,
restoring mangroves, and farming seaweed. Such interventions offer hope, but
they’re also inherently risky. Some may be ineffective, inequitable or even
harmful.
The pace of innovation is now outstripping the capacity to responsibly
regulate, monitor and evaluate these interventions. This means current and
future generations may not be getting value for money, or worse – the chance to
avoid irreversible change may be slipping away.
In our new research, published in
Science, we reviewed the latest evidence on
known and perceived risks of new ocean-based climate interventions. We then
gathered emerging ideas on how to reduce those risks.
We found the risks aren’t being widely considered, and the benefits are
unclear. But there are emerging assessment tools and planning frameworks we can
build on, to plan ocean-based climate actions that meet humanity’s climate
goals."
