Since Eruption Day, the climate of the world has been altered significantly. Not only have weather patterns been affected, the average world temperature has dropped and the ice has more claimed large tracts of land for itself. The world as we know it has been plunged into a sort of premature ice-age, with the temperatures not as cold as the last ice age and less ice covering up land in the north.
Climate Change post-Eruption Day
Predictions of numerous geologists pre-eruption day on the sopervolcano Yellowstone erupting was proved right in part, with many theories being disproven.
Predictions of a Volcanic winter came true in a major fashion. What had occured numerous times in history occured again, but in a heavily intensified manner than before. Ash and sulfur dioxide were pumped into the air in a large manner by the supervolcano. The eruption was the largest in the world since the Toba explosion some 70,000 years ago and caused a small chain reaction in the explosion of volcanoes around the chain of fire. This would lead to the creation of new land at a largely rapid rate, but also cause numerous Tsunamis which would affect various nations on the Pacific Rim.
The Volcanic winter following Eruption day would not end so quickly. What would follow the eruption would be something which would come to be reffered to as the Decade of No Summers in later years. For more than a decade, the world would be locked in a cold age as ice caps began to once more expand from the poles and the temperature grew cold, with no summer to speak of.
