the deliberate large-scale manipulation
of an environmental process that affects the earth's climate,
in order to reduce global warming.
Geoengineering incorporates many different and diverse sciences and processes.
This fact makes it nearly impossible to debate the 'Implementation of Geoengineering Solutions' to lessen the impacts of anthropogenic climate change as a single proposition.
For example one Geoengineering solution is Carbon Capture and Storage.
This Geoengineering process seeks to capture and store carbon dioxide and other greenhouse gases from the atmosphere.
This geoengineering solution enjoys 100% global support for its immediate implementation.
However geoengineering processes which are included in the Solar Radiation Management category, which seeks to reflect a level of sunlight away from the earth are very controversial, and are the focus of much debate.
WHAT IS BEING DEBATED
Despite mounting evidence that severe climate change could emerge rapidly, the global reduction of carbon emissions remains alarmingly elusive.
As a result, concerned scientists are now asking whether geoengineering might be able to limit climate change impacts enough to curtail the worst effects of it.
Recent prominent reviews have emphasized that such schemes are fraught with uncertainties and potential negative effects and, thus, cannot be a substitute for comprehensive mitigation.
Others argue if geoengineering gives governments an easy way to curtail the effects of climate change, they may dramatically reduce their commitments to de-carbonizing their economies.
However as unabated climate change could itself prove extremely risky, almost outside our control, there is unanimous support from all sectors for expanding geoengineering research.
As such research is considered, a process for ensuring global transparency and cooperation within the sciences of geoengineering.
WHO SHOULD DECIDE
The international mechanisms most applicable to geoengineering methods and their impacts have not been developed for the purpose of regulating geoengineering, and for some methods there are as yet no regulatory mechanisms in place.
The greatest challenges to the successful deployment of geoengineering may be the social, ethical, legal and political issues associated with governance, rather than scientific and technical issues.
So who should make the final decision as to WHEN, IF & HOW Geoengineering Solutions are implemented or not.
