Is Geoengineering a Bad Fix?

    Scientists say that geoengineering methods intended to counteract the effects of global warming could actually result in a decrease in monsoonal rainfall in certain regions.

     A new study from the National Center for Atmospheric Research says that, although global warming alters worldwide precipitation patterns, geo-engineering to counteract would too.  Global warming due to greenhouse gases would cause a 7% average increase in precipitation compared to preindustrial conditions.  However geo-engineering methods, like capturing carbon dioxide before it enters the atmosphere or launching mirrors into orbit to reduce global surface temperatures, would decrease monsoonal rains in some regions by 5 to 7% with a worldwide average decrease of 4.5% compared to preindustrial conditions.
