How do volcanoes affect the climate? | Environment | The Guardian
When volcanoes erupt, they emit a mixture of gases and particles into the air. global temperature change after multiple eruptions proves a strong link. Guardian columnist and author Rebecca Solnit urges you to show your. Now, you can add yet another problem to the climate change hit list: . that volcanic activity across the island increased as much as fold. Volcanic eruptions are responsible for releasing molten rock, or lava, from The amounts put into the atmosphere from a large eruption doesn't change the.
The Earth, we are learning yet again, demands respect. An earlier version of this story misstated the annual rate of land rebound in the coming decade.

Yanping Wang A young starfish at 5x magnification. Below is an overview of materials that make their way from volcanic eruptions into the atmosphere: Particles of dust and ash Volcanic ash or dust released into the atmosphere during an eruption shade sunlight and cause temporary cooling.
Larger particles of ash have little effect because they fall out of the air quickly. Small ash particles form a dark cloud in the troposphere that shades and cools the area directly below. Most of these particles fall out of the atmosphere within rain a few hours or days after an eruption.
But the smallest particles of dust get into the stratosphere and are able to travel vast distances, often worldwide. These tiny particles are so light that they can stay in the stratosphere for months, blocking sunlight and causing cooling over large areas of the Earth.
Sulfur Often, erupting volcanoes emit sulfur dioxide into the atmosphere. Sulfur dioxide is much more effective than ash particles at cooling the climate.
The sulfur dioxide moves into the stratosphere and combines with water to form sulfuric acid aerosols. The aerosols can stay in the stratosphere for up to three years, moved around by winds and causing significant cooling worldwide.
