In June, the weather turned cold and it snowed. The winter of 1815-1816 was normal, but that changed in late spring. The year 1816 became “the year without summer.” Through June and July — even into August — cold temperatures and heavy snows were the norm. In most cases, farmers were not able to get a crop into the ground, let alone harvest. People became desperate. No one knew what to do.



No one knew the reason for this sudden change in climate, although many theories circulated among the population. Some people thought a star had passed between the sun and earth, cutting off the light. Others attributed the change in climate to sunspots. [1]

Today, scientists believe the cold summer of 1816 was the result of the eruption the previous year of Mount Tamboro, in what is now Indonesia. This massive eruption, estimated by some scientists to be the largest in ten-thousand years, added to dust already in the atmosphere from two earlier volcanic eruptions, one in the West Indies in 1812 and another in the Philippines in 1814.
