1991: The second largest volcanic eruption of the 20th Century began as Mt. Pinatubo injected 15 to 30 million tons of sulfur dioxide 100,000 feet into the atmosphere. 343 people were killed in the Philippines as a result of the eruptions, and 200,000 were left homeless. Material from the eruption would spread around the globe, leading to climate changes worldwide as the sun’s energy was blocked out and global temperatures cooled by as much as one degree Fahrenheit. 1992 was globally one of the coldest since the 1970s.
