Prof. Anya Waite is leading a delegation from Dalhousie University's Ocean Frontier Institute to attend the 27th annual Conference of the Parties of the UN Framework Convention on Climate Change — better known as COP27 — in Sharm el-Sheikh, Egypt, starting Sunday. They plan to share ways the deep blue carbon sink acts as a buffer and impacts climate forecasts.
Waite said most people know that rainforests are the lungs of the planet, keeping temperatures down and filtering the air.
But there is a danger that these carbon sinks will turn to emitters as the waters warm, melting caps of frozen methane and other greenhouse gases that lie scattered on the sea floor, she said. Waite said such "blue carbon ecosystems" help retain emissions, in addition to enhancing biodiversity. But it is further offshore that the biggest carbon stores are to be found, she said.
"There's a whole lot more shipping in the St. Lawrence, and those animals are now coming in contact with ships way more often, bringing an already endangered species to the brink of collapse," Waite said.
