Solar Radiation Management
Solar Radiation Management
This will be an introductory discussion on the topic of solar radiation management geoengineering (SRM). SRM is a theoretical proposal for reducing some of the risks of climate change by reflecting away some sunlight, for instance by spraying reflective particles in the upper atmosphere. The 2-hour session will introduce the science and socio-political implications of SRM and will feature presentations from the University of Cape Town (UCT) team members.
The second part of the meeting will be dedicated to discussions among the participants, first in small groups, followed by a plenary session to conclude the event. The small groups of invite-only participants will review the risks and benefits of SRM and consider how the Southern African region should engage with the issue.
If Solar Radiation Management were ever implemented, it would involve deliberately reflecting away a small fraction of sunlight to reduce global temperatures. Scientists are clear that it is not an alternative to emissions cuts, but SRM is the only known method for quickly stopping the rise in global temperatures. As such, it might prove the only way to meet the agreed global warming limits of 1.5°C and 2°C, and so it has the potential to significantly reduce global warming impacts while the world decarbonises.
However, it could have dangerous side effects, could cause political tensions, and could distract leaders from making necessary emissions cuts, and so SRM also has the potential to be very damaging. The stakes are high and it is therefore important to have an informed global conversation about SRM geoengineering.
In preparation for the workshop, we would suggest that all participants read the following article, which is a comment in Nature that sets out the potential benefits and risks of SRM and calls for developing country leadership: Developing countries must lead on solar geoengineering research. We also recommend the following video “To geoengineer or not to geoengineer” produced by the Red Cross Red Crescent Climate Centre.
