Experts call for global moratorium on efforts to geoengineer climate

Techniques such as solar radiation management may have unintended consequences, scientists say

Governments should place a moratorium on efforts to geoengineer the planet's climate, as greenhouse gas emissions continue to rise and the climate crisis takes hold, a panel of global experts has urged.

Geoengineering is highly controversial, but discussions of its feasibility are gathering pace as the impacts of extreme weather, driven by climate breakdown, grip the planet. There is no global agreement on geoengineering, and no rules on what countries, or businesses, can do.
