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 researchers used a simple energy balance analysis to explain how the Earth’s water cycle responds…

Unprecedented Glacial Chutzpah – just in time for IPCC AR5

From the European Geosciences Union  comes some unprecedented chutzpah with this statement from one of the authors at the end of the press release: “This study has been conducted with scientific motivations, but if the insight it provides can motivate political decisions to mitigate anthropogenic impact on climate and glacier retreat, it will be an…

New paper blames about half of global warming on weather station data homogenization

From the told ya so department, comes this recently presented paper at the European Geosciences Union meeting. Authors Steirou and Koutsoyiannis, after taking homogenization errors into account find global warming over the past century was only about one-half [0.42°C] of that claimed by the IPCC [0.7-0.8°C]. Here’s the part I really like:  of 67% of…
