Aerosols Make Cumulus Clouds Brighter but Shorter Lived
Computer simulations show that although adding aerosol particles to clouds can make them more reflective, the cooling effect from clouds is largely counterbalanced by a reduction in overall cloud cover.

Iron Fertilization Might Not Make Oceans Better Carbon Sinks
New research suggests more iron during the last ice age did not mean more algae production in the equatorial Pacific, pointing to possible futility of a controversial geoengineering idea.
