A mysterious volcanic eruption in 1452 or 1453 triggered the first large sulfate spike in the 1450s, succeeded by another spike in 1458 caused by another mysterious eruption. The eruption caused a severe volcanic winter, leading to one of the strongest cooling events in the Northern Hemisphere. This date also coincides with a substantial intensification of the Little Ice Age.
