June 5, 2017 — President Donald Trump’s decision Thursday to withdraw the United States from the Paris climate accord will hamper efforts to stem global warming throughout the world — the primary cause of rising ocean temperatures that pose the single greatest threat to Hawaii’s marine ecosystems.
Responsible for more CO2 emissions than any country save for China, the United States’ exit from the Paris agreement was met with dissension not only from some within Trump’s own administration but also from environmental activists, business leaders across the country and political leaders across globe.
Scientists in Hawaii also balked at Trump’s move, saying the state will not escape the subsequent ripple effect as it works to mitigate environmental impact to coral reefs on the heels of back-to-back years of coral bleaching in 2014 and 2015, the latter of which was part of the third global bleaching event in history.
“If we don’t solve the global emissions (problem) … everything that we do on reefs is substantially harder,” said Thomas Oliver, ocean acidification program manager with the Pacific Islands Fisheries Science Center. “The Paris accord so far represents the best international response we’ve ever had to deal with the problem.”
Dr. Bill Walsh, West Hawaii aquatic biologist for the Hawaii Division of Aquatic Resources, said concerns extend beyond a departure from the Paris agreement to the administration’s general attitude toward climate change and the federal agencies tasked with combating it.
“Even apart from the Paris accord, if the withdrawal or rather the attack of the administration on scientific organizations (like) NOAA or the Environmental Protection Agency — we work hand in hand with them,” he said. “A lot of our ability to effectively monitor the reefs over these years has been due to money the state gets directly from NOAA. We’re all sort of intertwined here.”
Walsh and Oliver each helped develop the Coral Bleaching Recovery Plan, a detailed report synthesizing input from international and local experts along with relevant scientific literature on the problem.
Released in March after roughly a year of work, the strategies the report recommends revolve around establishing networks of no-take Marine Protected Areas (MPAs) and Herbivore Fishery Management Areas (HFMAs).
Strategies also include spatial management of coral reef areas with inherent resiliency to bleaching or a high potential for recovery from bleaching. The final recommendation involves increased enforcement.
