Geoengineering climate Change: Treating the symptom over the cause?

The present article by It is important to note that Crutzen argues that this idea be studied in depth and openly before any large scale action is taken. A basic assumption to this approach is that we, humans, understand the Earth system sufficiently to modify it and 'know' how the system will respond. Cicerone in his article argues that open discussion of these ideas is an appropriate means to explore engineering solutions to climate change, and further proposes a protocol to prevent inadvertent abuse of geoengineering experiments. These papers evoke both scientific and ethical issues that should stimulate discussions on the engineering of Earth's climate system.
