Sulfur dioxide is the substance that lowers air temperatures after a volcanic eruption by reflecting sunlight and causing a cooling effect on the lower atmosphere.
Sulfur dioxide is the substance that may lower air temperatures after a volcanic eruption. When sulfur dioxide is released into the atmosphere during an eruption, it forms droplets of sulfuric acid that reflect sunlight back into space, leading to a cooling effect on the lower atmosphere.
Volcanic CO2 emissions can contribute to long-term climate warming, but short-term cooling is primarily associated with sulfur dioxide. An example of this cooling effect is the eruption of Mount Pinatubo in 1991, which resulted in a measurable drop in global temperatures for at least 2 years.
Volcanic eruptions release various gases and particulates, impacting the global climate temporarily. The release of sulfur dioxide and the formation of sulfuric acid droplets play a crucial role in lowering air temperatures after a volcanic event.
