Despite great concern regarding the likely net negative effects of global warming in the long run, astonishingly little progress has been made to prevent such outcomes.

Though efforts to reduce global greenhouse gas (GHG) emissions have faltered, there do exist other climate policy options that may offer timely and relatively cheap methods for offsetting some of the harmful effects of climate change.

At this event, panelists discussed the emergence of geoengineering as a policy option and the congressional hearings being held on the subject.

Climate change might pose a grave threat, but emissions containment is both costly and politically impractical, so climate engineering is beginning to look like the last best hope.

Gradually lowering greenhouse gas emissions would be worthwhile were all states to join in the effort, but absent such strong, broad-based action, countries should explore other means of limiting harm from climate change.
