The scariest part of following the science on climate change is the revelation of positive feedback mechanisms like the release of methane deposits that will accelerate warming. So it is always heartening to hear of scientific news that suggests other forces at work that will give us more time to address climate change. A letter in Nature: Geoscience suggests that natural aerosols emitted by plants that mitigate the effects of greenhouse gases will increase with warming, a negative feedback mechanism.
And in other news, a recent advance in nanotechnology, an area of science that promises to advance every other area of science, has produced nanostructures that can significantly increase solar cell efficiency.
And finally, the completely awesome Nest thermostat just got another update.
