Before Geoengineering, Understand The Carbon Cycle, Studies Say

the Earth's natural biogeochemical cycles must be better understood before Geoengineering efforts are undertaken as a means to help mitigate climate change, according to two studies in Nature Geoscience which discuss what drove large-scale changes to the carbon cycle nearly 100 million years ago. Both research teams conclude that a massive amount of volcanic activity introduced carbon dioxide and sulfur into the atmosphere, which in turn had a significant impact on the carbon cycle, oxygen levels in the oceans and marine plants and animals. read more
