Countries around the world are increasingly turning to nature to help alleviate the impacts of climate change. Forests, grasslands and wetlands are already considered as “natural climate solutions.” Now, some scientists are asking: could kelp forests be part of the solution too?
As some of the fastest growing species on Earth, kelp form lush underwater forests along temperate coastlines. In addition to supporting marine biodiversity, sustaining fisheries and contributing to local economics and livelihoods, kelp forests also absorb carbon. But their role in climate change mitigation remains uncertain.
In the first national assessment of Canada’s kelp forests, our research team set out to estimate how much carbon these ecosystems might be capturing and storing in the ocean, and whether that carbon stays out of the atmosphere long enough to be considered a natural climate solution.
