Some governments are exploring geoengineering as a way to reduce or delay climate change. Geoengineering could technically take climate decisions away from all but the richest countries. Computer models show that stratospheric interventions to reduce sunlight and lower temperatures may benefit some temperate zones, but negatively impact Asia’s monsoons with important social and agricultural consequences.
The Big Downturn? Nanogeopolitics, ETC Group’s new 68-page report on global governance of nanoscale technologies, is an update of our 2005 Nanogeopolitics survey. In the intervening five years, policymakers – some kicking and screaming – have begun to acknowledge that fast-tracking nanotech has come at a price and that some sort of regulation is needed to deal with at least some of the risks nanoscale technologies pose.
