Abstract

Mankind has always wanted to submit climate and weather to their own will. Geo-engeneering, a new science, whose aim is to produce the desired weather and climate effects, is gaining relevance in the global scenario. From cloud seeding to GMO trees to enhance CO2 absorption, this article describes new emerging technologies and the potential role they could play in the climate change challenge. However, the diverse ends of our complex environmental system might cause unexpected consequences. Legislators must favor the precautionary principle as suggested by the UN Convention on Biological Diversity.
