To speed up magma, add water
It was a bit like making a CT scan of a patient's head and finding he had very little brain or making a PET scan of a dead fish and seeing hot spots of oxygen consumption. Scientists making seismic images ...
Climate models don't over-predict warming, study shows
If you listen to climate change skeptics, Earth's surface hasn't warmed appreciably in the last 15 years, and any "record" set last year is just the result of the planet doing what the planet naturally does.
Climatic history study suggests pre-Columbian Mesoamerican society's demise was more complex than just weather
Interaction of Atlantic and Pacific oscillations caused 'false pause' in warming
The recent slowdown in climate warming is due, at least in part, to natural oscillations in the climate, according to a team of climate scientists, who add that these oscillations represent variability internal to the climate ...
