    Rock Samples Indicate Water is Key Ingredient for Crust Formation

    By examining the cooling rate of rocks that formed more than 10 miles beneath the Earth’s surface, scientists led by The University of Texas at Austin Jackson School of Geosciences have found that water probably penetrates deep into the crust and upper mantle at mid-ocean spreading zones, the places where new crust is made.

    As Predicted: A Rising Tide of Migration

    “With sea levels on the rise, several island nations are scrambling to stay above water and ensure citizens will have a place to go when the ocean engulfs their homeland. The humanitarian-crisis phase of climate change has officially begun.”

    I hear that the Archean Earth Spewed lava and was hot, (While much later, “Snowball Earth,” Apparently was not), Some have said that life sprung out of Spreading-ridge-type stew, Photosynthesis seems likely Based on carbon records, too.

Science for the Planet: In these short video explainers, discover how scientists and scholars across the Columbia Climate School are working to understand the effects of climate change and help solve the crisis.
