volcanic dust
In addition to the effects of the Gulf War burning oil fields, volcanic eruptions in the Philippines are also polluting the earth's environment.
So part of the purpose of the expedition to Mount Everest was to take air and ice samples to see how the volcanic dust from the eruption affected earth.
When a volcano erupts, it sends a large amount of volcanic dust into the atmosphere, and the largest amount of volcanic dust is sulfur dioxide. With the wind, these sulfur dioxide will enter the upper atmosphere, and through action, these sulfur dioxide is converted into sulfuric acid particles.
At altitudes of 15 to 30 kilometers, there is no great vertical movement, so the sulfuric acid particles converted from sulfur dioxide stay in the horizontal advection plane, and can stay there for years. This creates a thick mantle of drapelike dust in the upper atmosphere. This mantle absorbs sunlight and heats the stratosphere, but the sun radiates toward the ground and cools the lower atmosphere.
Such is the damage caused by volcanic dust in the Philippines. The eruption of Mount Pinatubo in the Philippines, the largest of its kind this century, sent an estimated 20 million tons of sulfur compounds into the upper stratosphere, thereby lowering the earth's atmosphere by an average of several degrees Fahrenheit.
It not only caused harm to the Chinese people, but also brought a lot of influence to the whole earth. Volcanic dust continues to drift around the world, not only to people, but also to plants and animals.
Global temperature drop on the human body, the environment will not adapt to the impact.
