[Update from Nagoya 30 October 2010. Global moratorium passes.]

Delegates to the world summit on biodiversity here are calling for a moratorium on climate engineering research, like the idea of putting huge mirrors in outer space to reflect some of the sun’s heating rays away from the planet.

Climate engineering or geoengineering refers to any large-scale, human- made effort to manipulate the planet to adapt to climate change.

Representatives from Africa and Asia expressed concern about the negative impacts of geoengineering during the opening week of the 10th Conference of Parties (COP 10) to the United Nations Convention on Biological Diversity (CBD), Oct. 18-29. They were joined by civil society organisations in calling for a moratorium on geoengineering experiments.

The geoengineering proposals include installing giant vertical pipes in the ocean to bring cold water to the surface, pumping vast amounts of sulphates into the stratosphere to block sunlight, or blowing ocean salt spray into clouds to increase their reflectivity.
