Read moreGeoengineering report: Scientists urge more research on climate intervention
Deep cuts in greenhouse gas emissions, while necessary, may not happen soon enough to stave off climate catastrophe. So, in addition, the world may need to resort to so-called geoengineering approaches that aim to deliberately control the planet's climate. That's according to a National Research Council committee that today released a pair of sweeping reports on climate intervention techniques.
