Considering what you know about greenhouse gases and their effects on the Earth's mean surface temperature. How might a volcanic eruption effect/change Earth's mean surface temperature? Feel free to do a little more research before answering this question.

The effects of GHG on earth's surface temperatures leads to increase of warming  of the planet.

Explanation:

On considering the impacts of the greenhouse gases on the atmosphere and their effects on the earth's mean surface temperatures. The volcanic eruptions affect the earth's mean surface temperatures as they release carbon and other gases that block the sun rays and create effects of cooling. They also increase the amount of carbon concentration at the lower atmosphere and elevate the global temperatures.

Ithink that its like 15 mph.
