Groundbreaking study provides new evidence of when Earth was slushy

At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet. Results provide the first direct geochemical evidence of the slushy planet -- otherwise known as the 'plume-world ocean' era -- when sky-high carbon dioxide levels forced the frozen Earth into a massive, rapid melting period.
