Geoengineering and the UNFCCC: Presentation for PACC Bangkok, October 3, 2009 Diana Bronson, ETC Group
Outline of briefing (1) what is geoengineering; (2) examples: theory, status, problems (3) recommendations on technology language
Geoengineering: the large-scale, intentional manipulation of the climate, particularly to counter effects of climate change …Or a planetary techno-fix
Wide variety of techniques Three general categories
! Carbon dioxide removal and sequestration (CDR) ! Solar Radiation management (SRM) ! Weather modification
Policy credibility? ! Royal Society ! National Academies of Science
! American Meteorological Society
! Upsurge of media ! Parliamentary & Congress Committees
! American Enterprise institute
! Bjorn Lomborg ! Heartland, Cato, Hoover ! DARPA ! Edward Teller, Lowell Wood
Ocean fertilization: the theory ! Add “nutrients” to ocean to stimulate algae growth
! Increase CO2 uptake of oceans
Ocean fertilization: the status ! 13 experiments to date ! Inappropriate commercial interest: Climos, Planktos, ONC
! CBD moratorium ! London Convention resolution and process ! Upcoming experiment in Antarctic Sea over 40,000 sq km (Climos)
OIF: the problems ! Disturbance of marine food web ! Unpredictable effects on marine ecosystems ! Oxygen deprivation ! CO2 sequestration would require widespread and cumulative process
! No small scale, no control patch Cf. A. Strong et al. “Ocean Fertilization: Time to Move on” Nature, Sept 17 09.
Other ocean technologies Cloud whitening
Ocean Mixing
Other CDR Technologies ! Artificial trees ! Carbon sucking machines
! Geoengineered algae
! biochar
Sulphur in the stratosphere: the theory ! Solar radiation management technology
! Inspired Mt Pinatubo ! Reduce warming
without changing GHG composition
Sulphates : the status ! Top rated technology in Royal Society report ! NOVIM report on technical research, development and deployment chaired by Steven Koonin
! Increasing academic attention ! Seen as “Plan B”
Sulphates: the problems ! Ozone depletion ! Regional weather impacts – droughts ! Continued ocean acidification ! Less blue skies ! Less solar power ! Sudden rapid warming if stopped ! High risk, unpredictable
Other SRM technologies ! Trillions of space mirrors
1.5 million km from earth
! Cloud whitening ! Painting surfaces white ! Covering deserts in reflective plastic
Weather modification ! Began in 1830s ! Used as a military
technique in Vietnam
! Cloud seeding for precipitation
! Hurricane redirection ! Gates patent on hurrican suppression by cooling surface water
! 1978 ENMOD
Common problems of geoengineering ! Alternative to mitigation ! Large-scale by definition ! Potential unilateralism ! Unreliable ! Unequal impacts ! Private sector incentives ! Lack of regulation (CBD, ENMOD)
Overall principles ! precautionary principle ! Respect for international law ! No unilateral action ! Full consideration of potential negative social or environmental impacts ! Open and transparent process with full civil society participation ! Fair, full and equitable representation and participation of developing countries ! Involvement of relevant UN treaty bodies
Geoengineering at UNFCCC Exclusion Option: “The provisions related to enhanced action on the development and transfer of technology in this text do not apply to geo-engineering technologies…”
Geoengineering at UNFCCC Precautionary language
! Assess technologies before they are deployed ! No experimentation ! No unilateralism
