Geoengineering approaches to reduce climate change unlikely to succeed

From the EGU: Heavy rainfall events can be more common in a warmer world (Credit: Annett Junginger, distributed via imaggeo.egu.eu) Reducing the amount of sunlight reaching the planet’s surface by geoengineering may not undo climate change after all. Two German … Continue reading

Study: lack of cloud physics biased climate models high

The Hockey Schtick brings this to our attention. It seems Dr. Roy Spencer was prescient with his observation: “The most obvious way for warming to be caused naturally is for small, natural fluctuations in the circulation patterns of the atmosphere … Continue reading
