  • Turning CO2 to Stone
    October 24, 2016

    Earth has limits to the amount of carbon dioxide in its atmosphere before the environment as we know it starts to change. Too much CO2 absorbed by the oceans makes the water more acidic. Too much in the atmosphere warms the planet. With emissions from our carbon-based economies rising, scientists at Columbia University’s Lamont-Doherty Earth Observatory are developing way to prevent CO2 produced by power plants and industries from ever entering the atmosphere, and they are exploring ways to take CO2 out of the environment.

  • How Does Earth’s Continental Crust Form? Scientists Have a New Bottom-Up Theory
    February 22, 2016

    Deep beneath Alaska’s Aleutian Islands, down where the pressure and temperatures have become so high that rock starts to flow, new continental crust is being born. Scientists have long believed that continental crust forms in volcanic arcs – they know the magma brought up in the arcs’ volcanoes is geochemically very similar to continental crust. The lingering question has been how exactly that happens. While the magma that reaches the surface is similar to continental crust, the lower crust beneath volcanic arcs is quite different from the lower half of continental crust.
