Large volcanic eruptions are known for making significant impacts on the weather and\u00a0climate<\/a>.<\/p>\nUnlike the eruption that occurred in Tonga, however, many others caused the climate to cool. This is because volcanoes typically emit sulfur dioxide into the atmosphere, which results in a cooling effect, according to Purkis.<\/p>\n
