EarthSky has an interesting report today based on some research that was reported this week at the Geological Society of America’s annual meeting in Seattle on climate impacts of the Yellowstone volcanic eruptions that took place 630,000 years ago. The study showed that there was not one but two closely-spaced eruptions that sent out a large quantity of volcanic material which slowed down the warming of the planet that was taking place at that time as Earth moved out of a major ice age.
