Mantle plumes are thought to be narrow streams of hot rock rising through Earth's mantle and spreading out like a mushroom cap under the crust. The buoyancy of the material, some of it molten, causes the crust to bulge upward. The theory of mantle plumes was proposed in the 1970s to explain geothermal activity that occurs far from the boundary of a tectonic plate, such as Hawaii and Yellowstone.
Life in the so-called Islamic State (ISIS) is not exactly paradise. Children are indoctrinated, women are severely oppressed, and infidels are beheaded. Ancient cultural artifacts and historical treasures are destroyed. Liberating people conquered by ISIS, therefore, is good not only for humanitarian reasons but for archaeological ones, as well.
Now, it appears there is yet another reason to defeat ISIS: It might be good for the planet.
A new study published by Princeton University and the World Bank shows that oil production in ISIS-controlled areas has fallen by over 70%, from 56,000 barrels per day in December 2014 to 16,000 barrels per day in 2016.-->
