Cutting greenhouse gas emissions may not be enough to stave off climate catastrophe. That's why researchers are examining geoengineering approaches that could potentially help control the planet's climate. Now, though, scientists are urging further research into the matter before any steps are taken.

"I, for one, am concerned with the continuing rise in CO2 concentrations without clear efforts to reduce emissions," said Joyce Penner, one of the researchers, in a news release. "The widespread impacts from these increases are readily apparent, and the cost of climate change impacts is likely to be...
