High-risk geoengineering projects are proceeding in violation of UN moratoria

MONTREAL, SYDNEY, UTQIAGVIK, SANTIAGO—On World Oceans Day, members of a global coalition formed by 195 organizations on 45 countries are raising the alarm about the threat of geoengineering to delicate, life-sustaining ocean ecosystems worldwide. The Hands Off Mother Earth (HOME) Campaign today called on civil society and government officials worldwide to vigorously oppose marine geoengineering experiments.

A recent announcement of thefirst open-air test of solar geoengineering technology in Australiais one of several types of geoengineering that could cause permanent damage to ecosystems if implemented at scale. However, Australia is not the only such dangerous, precedent-setting experiment.

“Geoengineers are flying in the face of global moratoria agreed at the UN,” said Silvia Ribeiro of ETC Group. “The potential for large-scale versions of these projects—driven by the fossil fuel industry’s motivation to keep extracting, selling and burning—poses a clear and present danger to our oceans.”

CIVIL SOCIETY SPEAKS OUT: EXPERIMENTS POSE LOCAL AND GLOBAL DANGERS

Risky marine geoengineering experiments at a glance:

Experiment: Marine Cloud Brightening (spraying sea water to brighten clouds to reflect sunlight into space)
Actors:Southern Cross University and other Australian institutions
Location: Coastal waters near Townsville, Australia
Risks to oceans: At scale, could shift precipitation patterns regionally or even globally; additional ocean acidification and coastal pollution of coral reefs from continued use of fossil fuels.

Experiment: Glass microbubbles on sea ice formations (intended to deflect sunlight away from ice)
Actor:Ice911 project
Location: Utquiagvik (formerly Barrow), Alaska and Winnipeg, Canada
Risks to oceans: Potential changes to weather patterns, precipitation and sea currents; unknown effect of synthetic microbubbles entering food chain, potentially inhibiting growth of flora disrupting marine food chains; ocean acidification from continued use of fossil fuels. The testing isopposed by Indigenous groups in the area, who also have questions on the potential impacts of inhalation of the microbubbles.

Experiment: Ocean Fertilization (stimulating plankton growth to hypothetically sequester carbon)
Actor:Oceanos
Location: Coastal waters of Chile and Peru
Risks to oceans: Deoxygenation creating “dead zones”; potential growth of toxic algae; removal of nutrients from water disrupting down-current ecosystems.

Experiment: Artificial Upwelling (bringing nutrient-rich deep ocean water to the surface to stimulate plankton growth, hypothetically removing CO2)
Actor:GEOMAR Helmholtz Centre for Ocean Research, Germany
Location: Coastal waters off Callao, Peru
Risks to oceans: Potential release of CO2 stored in deep ocean; may increase ocean acidification; disruption of marine food web and fisheries.

Geoengineering is a set of proposed technologies based on the idea that instead of reducing emissions to prevent catastrophic global temperature increases, we can instead impose a series of large-scale interventions to manipulate planetary systems. These include a variety of unproven schemes for blocking sunlight or reflecting it back into space, or removing carbon dioxide from the atmosphere.

“Geoengineering does not address the causes of climate change,” said ETC’s Ribeiro. “Undertaking megaprojects that would change the dynamics and the chemistry of oceans is a high risk enterprise that entails serious uncertainties about impacts on marine ecosystems.”

Yet these high-risk technofix approaches are going ahead despite global opposition and international calls to take extremely precautionary approaches to marine geoengineering. The UN Convention on Biodiversity (CBD) passed a moratorium on ocean fertilization in 2008, and a moratorium on all forms of geoengineering (including open-air research) in 2010 [1]. The London Protocol of the London Convention adopted a ban on ocean fertilization in 2013.

The open-air testing of solar geoengineering technology in Australia therefore sets a particularly dangerous new precedent, opening a path to the use of a  risky technology that, if deployed at large scale, could be damaging to other regions and even the ocean ecosystems the researchers claim to be trying to protect.

“The Australian Government has consistently pandered to fossil fuel company interests by promoting false solutions to climate change that promote business as usual,” said Louise Sales from Friends of the Earth Australia’s Emerging Tech Project. “This potentially harmful Solar Radiation Management experiment on the Great Barrier Reef is no exception. To really address climate change, we need serious cuts to CO2 emissions, not distracting technofixes.”

This project in Australia claims to be for the protection of the Great Barrier Reef, but geoengineering will not address the main causes of the reef’s destruction (ocean acidification and coastal pollution). The project is connected to a geoengineering team that has been working to deploy the same cloud-brightening technique outside Monterey Bay In California.

Attempts to test ocean fertilization techniques off the coasts of Chile and Peru also contravene the London Convention and CBD moratoria. Therefore Oceaneos, an organization connected to  previous illegal experiments in Canada presents their activities as “ocean seeding,” arguing that it is a method to increase fish stocks.

“We reject the attempt to use ecosystem degradation or alleged improvements to fisheries as an excuse to justify the advancement of marine geoengineering. These experiments would violate international moratoria, and scientific evidence indicates that the risks and impacts far outweigh the supposed benefits.” said Samuel Leiva from Terram, in Chile.

Geoengineering entailsmany environmental, geopolitical and economic risks, that would be distributed unevenly in the world, favoring those companies and people that have already profited from climate change. Small experiments, either on land, or in the ocean or the air,  do not provide data about geoengineering on the climate or ecological systems. Instead, these projects function as a beachhead to justify larger experiments and investments—and open a path to their large-scale adoption.

Oceans and seas are crucial for communities and all life on the planet. Today, the HOME Campaign is renewing its call for a stop to all marine-based geoengineering experiments.
