Dalhousie University researchers to share research on how the deep blue carbon sink acts as a buffer and impacts climate forecasts
Lying in plain sight and lapping against our shores is what scientists describe as an unsung hero that has been quietly absorbing heat and keeping the world’s temperatures under control. And over the coming days, a group of Canadian researchers hopes to persuade the world that the ocean has a crucial role to play in fighting climate change.
Waite said scientists must understand the role oceans have played to date in mitigating climate change, noting it’s also important for coastal communities to know how they must adapt to shifting conditions. “The capacity of the ocean to absorb carbon is gently declining,” Waite said. “But then on top of that we’re seeing that there’s these … extreme events or rare events that can potentially release carbon in short notice. And we don’t really understand those.”
Changes in ocean temperatures also change water currents, she noted, adding melting glaciers from the Arctic put fresh water into the ocean and force marine animals to either relocate or adapt to their changed environments. Shifts in ocean circulation and temperatures also change animal behaviour, sometimes causing them to move in search of more comfortable environs that ultimately put them at greater risk.
