Geoengineering Approaches to Reduce Climate Change Unlikely to Succeed

Reducing the amount of sunlight reaching the planet’s surface by geoengineering may not undo climate change after all.  Researchers used a simple energy balance analysis to explain how the Earth’s water cycle responds differently to heating by sunlight than it does to warming due to a stronger atmospheric greenhouse effect.  Further, they show that this difference implies that reflecting sunlight to reduce temperatures may have unwanted effects on the Earth’s rainfall patterns.
