Records from the later Qin Dynasty say that during the last year of Jie ’s reign , ice formed during the summer mornings and frost occurred through July . Heavy rainfall toppled buildings , hot and cold weather arrived in disorder , and crops failed . Some scientists correlate this event with a volcanic winter , possibly due to the Minoan eruption of Thera circa 1628 BC
