Speaker: Janos Pasztor, executive director, Carnegie Initiative for Geoengineering Governance (C2G2)

The challenge for policymakers, therefore, is to assess the risks of researching, developing — and possibly deploying — geoengineering technologies against those of not deploying them, and relying only on other climate interventions, such as mitigation and adaptation.
Policy makers cannot make judgments on those risks by themselves. Scientists need to contribute, but policy decisions need to follow broad society-wide discussions, including key stakeholders at national and international levels. It’s all hands on deck, and here’s why.
