Volcano+caused+ice+age

==Antarctica 34 millions back then was never like what it is nowadays. It was a green swamp with only some ice. Suddenly, rather mysteriously, ice appeared on both Antand continued to expand down the equator and the global temperature had a significant decrease, yes an ice age was coming. Recently, scientists think they know the answer to how ice massively appeared on earth back then, and stayed until now.==

Series of gigantic explosions
==The thought that the ice age didn’t start straight away in a snap, it was due to a series of gigantic explosions. The Silicic Large Igneous Province erupted as hundreds of explosions between 50 and 15 million years and each eruption capable to make the earth cooler half degree lower (like how the 1991 Mount Pinatubo blast briefly cooled down the earth 0.5 degrees). The amount of ash accumulated from each eruption (it was said to me 710,000 times the volume of Sydney harbor), successfully caused the ice age, by blocking sunlight.== media type="custom" key="12893836" width="100" height="100" align="right"
