Although Rio+20 negotiators are discussing marine applications of geoengineering (so-called “ocean fertilization”) in the context of climate change and technological “quick fixes,” the wider issues of geoengineering, including so-called solar radiation management, are not being discussed. The UN Convention on Biological Diversity established a de facto moratorium on all forms of geoengineering in 2010. Nevertheless, some governments are continuing to look toward technological methods of blocking or reflecting sunlight and other planetary system adjustments. Rio+20 should make a firm statement banning geoengineering to prevent a handful of countries -- a new “coalition of the willing” from taking the Earth’s thermostat into their own hands.
