Climate & Geoengineering

Geoengineering is the intentional, large-scale technological manipulation of the Earth’s systems, often discussed as a techno-fix for combating climate change. Climate geoengineering technologies can be divided into three broad areas: so-called solar radiation management (reflecting sunlight to space), greenhouse gas removal and sequestration and weather modification.

Geoengineering can refer to a wide range of techniques, including: blasting sulphate particles into the stratosphere or 'whitening' clouds to reflect the sun’s rays; dumping iron particles in the oceans to nurture CO2 -absorbing plankton; firing silver iodide into clouds to produce rain or genetically engineering crops so their foliage can better reflect sunlight.

ETC Group opposes geoengineering and other false solutions to climate change (e.g., proprietary, genetically-engineered 'climate-ready' crops ) and supports peasant-led agroecological responses to the climate crisis.
