Deeper Updrafts: New Cloud Simulation Leads To Estimate Of 4°C Rise In Global Temperatures By 2100

A new paper in Nature estimates that global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions worldwide are not reduced -  due to a reestimate of the great unknowns of climate sensitivity, the role of cloud formation and whether this will have a positive or negative effect on global warming. This new higher estimate was created using real world observations of water vapor in cloud formation.  read more
