Recently, the volcanic eruption in the South Pacific island nation of Tonga has attracted widespread attention. The history of such natural disasters shows that certain volcanic eruptions can cause temperatures to drop or even trigger a Xiaoice period. So, is this volcanic eruption expected to slow global warming? How does it affect China?
The ash cloud of the Tonga volcano is more than tens of kilometers high, and even reached 500 kilometers in diameter at the beginning. Under the action of the wind, the ash cloud continues to spread southwestward, forming a dense ash cloud. But why do volcanic eruptions cause temperatures to drop?
Volcanic eruptions release large amounts of gas and rock, pushing them into the sky, such as the stratosphere. This high-altitude atmosphere is significantly different from the atmosphere near the ground. After volcanic ash enters the stratosphere, it floats there and does not fall to the ground. This creates a high-altitude ash cloud that reflects sunlight and causes temperatures to drop.
Historically, eruptions like the 1815 Mount Tambora are a prime example. The eruption transported large amounts of ash into the stratosphere of the Earth, causing temperatures to drop and snow in some areas in June, causing huge impacts on crop yields and causing social unrest.
Therefore, volcanic eruptions large enough may indeed cause global temperatures to drop, but this decline is difficult for humans to control. More importantly, it is too costly to solve the problem of global warming. In contrast, relying on human climate research and reducing greenhouse gas emissions to control global temperature rise is more feasible and controllable, helping to protect the earth's environment.
