GC43H:
Climate Intervention: Is Geoengineering in Earth's Future? II Posters

Submit an Abstract to this Session



Session ID#: 26627

Session Description:
The goal of last year’s ratified Paris accord to limit global warming to 2C (=3.6F) is unlikely achieved by voluntary emission reductions. Beyond greenhouse gas actions, climate intervention – a form of geo-engineering – is a means of limiting and even reducing the extent of global warming. This approach builds on humanity’s tradition of devising practical solutions to human needs and challenges, but is highly controversial as it presents a host of complex scientific, technical, economic, policy, and ethical challenges. The topic, therefore, requires public and professional discourse. This session will bring together speakers that address societal issues, policy and technical approaches, and a moderated, interactive panel discussion that engages the in-room audience and online viewers through a live-polling interface that gauges perceptions. The topic is both timely and controversial, so we are confident that it will have broad interest among meeting attendees, media, and general public.
