“If you go to some Taiwan beaches, you can see snow,” said Chieh-Shen (Jason) Hu, Ocean Initiative Coordinator for Taiwan’s Society of Wilderness, a 6,000-member organization similar to Sierra Club. Hu was referring to pervasive Styrofoam marine debris from western Taiwan’s oldest industry, oyster aquaculture.

As the Atlantic hurricane season kicks off this month, some coastal communities in the United States and small-island nations in the Caribbean are still recovering from last year’s record-breaking damage. At the same time, the heavy rains pounding the East Coast this week are part of a long-term trend towards more severe heavy rainfall events that have led to deadly floods and threaten critical U.S. military bases. Even on sunny days, cities such as Norfolk and Manila contend with high tide or “nuisance” flooding—a phenomenon that has increased as much as nine-fold since the 1960s, according to NOAA.

The Australian government’s recent Foreign Policy White Paper has been criticized for its underwhelming climate change section. Penny Wong, the current opposition leader in the Australian Senate, said that its acknowledgement of the need to support a more resilient Pacific region “rings hollow in light of the Abbott/Turnbull Government’s massive aid cuts.” But despite these criticisms, the Australian government continues to support a range of climate change initiatives in the Pacific. Increasingly, Australian Aid and its fellow donors, including USAID, JICA and GIZ, take a community-based approach to climate adaptation. Germany’s GIZ, for example, carries out community-level adaptation activities for all beneficiaries in the Pacific; and USAID has highlighted its community-level projects as important models. Our recent evaluation of some of these community-level adaptation programs in Vanuatu and Kiribati found that they provide some development benefits, including increased awareness, empowerment, cooperation, and self-esteem, but that it is too soon to tell whether this approach can reduce long-term vulnerability to climate change.

Climate change is “unfolding as we speak,” said John Agard, professor of Tropical Island Ecology at the University of the West Indies (UWI) at a recent public forum on island nations hosted in Trinidad by UWI’s Institute of International Relations. The “close coupling of terrestrial, coastal, and marine systems” in islands “results in fast-spreading impacts across systems,” said Roger-Mark De Souza¹, formerly the director of population, environmental security, and resilience for the Wilson Center, which partnered with UWI and American University’s Center for Latin American and Latino Studies to organize the event.

As the Climate Conference of Parties (COP-23) wraps up in Bonn, Germany, the prime minister of the tiny Pacific island nation of Tuvalu, which is sinking a few millimeters every year, made an impassioned call for transparency in the Paris Agreement “rule book” and for ratcheting up worldwide ambitions to reduce climate change.  While informal texts were drafted to guide implementation of the historic 2015 Paris Agreement, formal adoption of these rules will have to wait until COP-24, to be held in Poland next year.

The frontlines of climate change are the world’s shorelines. “It goes without saying that people living in coastal communities are already observing impacts,” said Erin Derrington, a coastal resources specialist working in the Northern Mariana Islands, at a recent Wilson Center event, the third in a series on coastal resilience presented in collaboration with the Hoover Institute and the Stanford Woods Institute on the Environment. “Although that is a challenge, it is also an opportunity and a driver for change and innovation,” said Derrington.

A threat looms on the sun-splashed horizon of the Republic of the Marshall Islands. The specter of climate change wraps its fingers around the islands, raising sea levels, salinizing soils, and sapping freshwater resources. These changes will make it even harder to sustain crops, which could push the population to even greater reliance on  processed foods, which has already spurred a diabetes epidemic on the islands. The major role played by the United States in the history of the Marshalls, where nuclear bombs were famously tested during the Cold War, may continue, as the impacts of another existential threat—climate change—continue to increase.
