Second, the text asserts that volcanic activities send dust and sulfur gas into air and these dark clouds block some sunlight and decrease the temperature in the Earth's surface. On the contrary, the speaker believes that if something likes this happens, the snow looks gray or a dramatic colorful sunset, but there is no report about this and also these eruptions were not enough strong to block the sunlight.
