Current human energy use has been calculated to be 15.7 terawatts and growing. Can non-fossil fuel renewable energy sources completely fulfill that need?
In this 'Earth: The Operator's Manual' video, Dr. Richard Alley explains that the human need can indeed be achieved through the combined effort of non-fossil renewable energy sources such as solar, hydro, geothermal, biomass and conservation.
Check out the video below as Dr. Alley shows examples of renewable energy sources at work as he adds up the total. Video courtesy of Youtube.
No surprise, August 2016 was the warmest August on record for global land/ocean surface combined, according to NOAA.
For an unprecedented 11th straight month a new record high monthly global temperature has been set.
There are major metropolitan areas along the coast that are actually sinking at a higher rate than oceans are rising.
New research looks at the influence of climate change on mid-latitude storm tracks.
As the planet warms there may be less impact on drought than previous studies have shown.
Climate model projections can become quite uncertain at more localized levels.
