CO2 underground could combat climate change

By Mackenzie Myers, @kenzwrites Despite the scariness of already-manifesting climate change, lawmakers and researchers worldwide have identified strategies to help us fight it. Expanding renewable energy, replacing coal with natural gas, and making machines more energy-efficient are just a few tricks humankind has up its sleeves. At the center of all this, of course, is a reduction in carbon dioxide (CO2) emissions. According to a new study, one key to accomplishing that goal may lie far beneath the surface of the earth and yet be more accessible than you might…

Carbon Capture: Transforming Greenhouse Gas into Rock

By Jonathan Trinastic @jptrinastic A few months ago, after drilling a well 400 meters deep, scientists in Iceland were repeatedly frustrated that the well kept breaking down. Retrieving the pump from the depths of the earth, they found its base covered in a scaly green and white material that clogged the end of the machine. Instead of feeling dismay over the equipment failure, the scientists celebrated. The crusty residue was calcite, a hopeful sign that the researchers had developed a new method to chemically trap carbon dioxide (CO2) underground and mitigate…
