What you should know... What geoengineering is How it would work Why it’s gaining attention What the social, ethical, & political issues are

What is Geoengineering? “Deliberate large-scale intervention in the Earth’s climate system, in order to moderate global warming.” -Royal Society 2009 “Scale and intent play central roles in the definition. For an action to be geoengineering, the environmental change must be the primary goal rather than a side effect and the intent and effect of the manipulation must be large in scale, e.g. continental to global.” -Keith 2000

What is Not Geoengineering? Imperial Palace Gardens, Kyoto, Japan. -Wylie Carr 2005

What is Not Geoengineering? -USGS Repeat Photo Project: http://www.nrmsc.usgs.gov/repeatphoto/gg_overlook.htm
