evidence: Carbon emissions from volcanic rocks can create global warming: study Greenhouse gas emissions released directly from the movement of volcanic rocks are capable of creating massive global warming effects—a discovery which could transform the way scientists predict climate change, a new study reveals. [...] "We calculated carbon-based greenhouse gas fluxes associated with the NAIP—linking measurements of the process that generated magma with observations of the individual geological structures that controlled gas emissions. These calculations suggest the NAIP caused the largest transient global warming of the past 65 million years.
