Environmental and Indigenous activists declared Thursday that "geoengineering fails again," welcoming the shutdown of a project that aimed to use "a reflective material to protect and restore Arctic sea ice." "While our climate impact simulations have shown promising results ... recent ecotoxicological tests have revealed potential risks to the Arctic food chain," the [Arctic Ice Project] team said. Panganga Pungowiyi, climate geoengineering organizer at Indigenous Environmental Network, called the decision "long overdue." "We are concerned for the community members in Utqiavik who were made to spread football fields of this material onto their frozen lake," Pungowiyi explained. "Our concerns about the reckless use of harmful materials were dismissed. We continually showed up in defense of free prior and informed consent, and made our presence known." "We continue to state firmly that nature is not a laboratory; it is a living entity we are in relationship with," the organizer added. "Geoengineering approaches do nothing to address the root causes of the climate crisis and instead delay real solutions, offering a free pass to polluters," [said Mary Church at the Center for International Environmental Law]. "Following the recent reaffirmation of the global moratorium on geoengineering at the U.N. biodiversity summit in Colombia, governments need to act to prevent harmful outdoor experiments."
