Oceans -- and ocean activism -- deserve broader role in climate change discussions
University of Washington

When President Barack Obama visited the shrinking Exit Glacier in September, he pointed to a very obvious sign of our warming planet literally at his feet.

Less visible, but perhaps more indelible, signs of changing climate lie in the oceans. A University of Washington researcher argues in the journal Science that people -- including the world leaders who will gather later this month in Paris for the latest round of climate change negotiations -- should pay more attention to how climate change's impacts on ocean and coastal environments affect societies around the globe.

"When people see headlines on big science findings that the oceans are acidifying, or sea levels are rising, they feel a sense of helplessness in the face of inexorable change," said lead author and UW professor of marine and environmental affairs Edward Allison. "Yet there are many things that people can, and indeed are already, doing."

"There's a lot of citizen action that can be done at a local level to prevent coastal damage," he continued. Examples cited in the paper include planting mangroves, saving coral reefs, or preventing beach erosion by planting coconut palms. In the Pacific Northwest, shellfish growers have begun to look at how to adapt their practices to account for more acidic seawater.

On a broader scale, Allison points to this spring's "kayaktivist" protesters in Seattle's Puget Sound, where people took to non-motorized marine craft to protest plans to capitalize on melting Arctic sea ice to extract more fossil fuels from the Arctic Ocean.

"I think the kayaktivists send a message that the future of the oceans, when it comes to energy generation, should be in renewables rather than in fossil fuels," Allison said. "You have this perverse situation where the melting of polar ice caps has allowed more economic exploitation of the Arctic, including for industries that contribute most to global warming."

Shifts in the world's oceans are long-lasting, extend far beyond the coast, and touch humans on many different levels, Allison said.

"The ocean is not just a place for economic activity," he said. "It's a place for inspiration, it's a place for enjoyment, it defines many cultures, and it's a place where we get some of our most nutritious food. What's at stake here? It's a timely moment to think about that."
