Dear Dr. Pachauri,
The undersigned organizations would like to express our concerns about the upcoming IPCC joint working group expert meeting on geoengineering to be held in Lima, Peru, June 20-22, 2011.
Geoengineering, the intentional large-scale manipulation of the Earth’s systems to modify the climate, is one of the most serious issues the international community will face in the decades ahead. The prospects of artificially changing the chemistry of our oceans to absorb more CO2, modifying the Earth’s radiative balance, devising new carbon sinks in fragile ecosystems, redirecting hurricanes and other extreme weather events are alarming. The potential for accidents, dangerous experiments, inadequate risk assessment, unexpected impacts, unilateralism, private profiteering, disruption of agriculture, inter-state conflict, illegitimate political goals and negative consequences for the global South is high. The likelihood that geoengineering will provide a safe, lasting, democratic and peaceful solution to the climate crisis is non-existent.
