How can explosive volcanic eruptions change climate?

Answer 1

The volcanic eruptions affect the climate through the gases and the dust particles that are thrown into the atmosphere during the eruptions. The effect of the volcanic gases and dust is that it may either cool or warm the surface of the earth.

Answer 2

The main effect on weather right near a volcano is that there is often a lot of rain, lightning, and thunder during an eruption. This is because all the ash particles that are thrown up into the atmosphere are good at attracting/collecting water droplets. We don't quite know exactly how the lightning is caused but it probably involves the particles moving through the air and separating positively and negatively charged particles.

Volcanic eruptions can alter the climate of the Earth for both short and long periods of time.

They can put ash into the atmosphere that it can block out the sun and cause nuclear winter. ( this is the reason the dinosaurs died because all the plants died because there was no sunlight)

Answer 4

The tonnes of dust thrown up by a large eruption covers the sky and prevents some of the sun's warmth getting through, sometimes for several years. So it can have a cooling effect on the climate.

Answer 5

Generally, there is cooling-down which may be followed by too much warming. In the short term, the powdered-rock dust cloud attracts water vapor and forms more clouds than usual, which reflect solar energy and cause global cooling and increased rainfall. In the longer term, much of the gas from eruptions is carbon dioxide which helps trap solar energy and contributes to global warming. Sulfur dioxide and other gases may also add to warming. The recent eruption of Mt Pinatubo, Philippines put enough dust and gas in the air to change global temperatures. The eruption of Mt Tambora, Indonesia in 1814 was so huge that many places around the world reported a much colder winter; the following spring and summer were also too cool, causing widespread crop failure and much human starvation. The eruptions of the Siberian Traps about 300 million years ago was deadlier than any other extinction event; almost all plant life died and rotted (forming the coal, oil and natural gas fuels we use today), then the atmospheric oxygen level quickly fell by half (from over 30% to less than 15%) which killed off most animal life. Some think a short ice age followed the Permian Extinction, and over the next few million years the temperature came up again even warmer than before as plant and animal life returned to a climax state.

Answer 6

Explosive volcanic eruptions emit a huge amount of gases, including CO2 and methane, both of which help keep the surface of the Earth from freezing solid. There are thousands of tons of ash, sulfuric acid and other particles that are thrown up to 50,000 feet into the atmosphere which shade the Earth and bring the temperature down. These clouds of particles often go completely around the Earth. In huge eruptions, what is called volcanic winter can occur year-round, shading the Sun, reflecting sunlight, and cooling the earth's surface greatly. The sulfuric acid has recently been shown to also cool the atmosphere.

Answer 7

It could make the energy flow worse. It could also pollute the air and make stormes and the oxygen flow low.

Answer 8

they send up lots of carbon dioxide which builds up the greenhouse gas layer
