As the climate crisis continues to worsen, climate finance remains a fraction of what is needed. The Climate Policy Initiative estimates that $579 billion was spent on average on climate finance in 2017/18. This includes domestic and international investment from both the public and private sectors towards climate mitigation and adaptation actions. Of this amount, only $30 billion—five percent—was allocated for climate adaptation. This amount stands in stark contrast to $180 billion, which the Global Commission on Adaptation estimates is needed every year to build resilience to current and future climate impacts. This catastrophic funding gap is intensifying climate security threats and elevating the vulnerability of people across the world, particularly in coastal urban centers.

Climate change will upend the 21^st century world order. It will redefine how we live and work, and change the systems of production, trade, economics, and finance. Even now, in the midst of a global pandemic, it is clear that climate change will be the defining issue of this century. In fact, COVID-19 has only underscored the inadequacy of our responses to global crises and heightened the urgency of this call to action. 21^st century diplomacy will have to raise climate ambition, shape the transformative systems change needed, and promote and facilitate new modes of multilateral collaboration.

At an event organized by the Coalition of Atoll Nations on Climate Change in December 2019, Tabitha Awerika, 21, from Kiribati, urged world leaders to listen to the climate science and to the pleas of those living in the South Pacific. “I will not leave the lands of my ancestors,” she said. “I will not abandon my motherland. I refuse to leave the only place I call home.”

In the Global South, climate change-induced resettlement requires a holistic and integrated approach, involving all stakeholders—state institutions, local customary and civil society institutions—and in particular respectful engagement with local traditional actors and networks. In a policy brief for the Toda Peace Institute, we examined climate change-induced resettlement from the Carteret Islands in the Pacific, a case which encompasses a broad range of issues relevant to future relocation efforts elsewhere. Those who seek to make this type of resettlement possible would do well to heed these lessons.

“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.
