The eruption in 1600 of a seemingly quiet volcano in Peru changed global climate and triggered famine as far away as Russia
Small disturbances can eventually have immense consequences. In the namesake example of the butterfly effect, the vortex spun from a butterfly’s wing creates tiny changes in the atmosphere that result in a hurricane half a world away. While that’s theoretically possible, no one has yet tried to blame the insect world for triggering a cyclone.
But a strong link does exist between the small particles suspended high in Earth’s atmosphere, such as those spewed from erupting volcanoes, and the overall climate down at the planet’s surface. High-altitude aerosols, especially in large numbers, block sunlight from reaching the ground and scatter it back into space, thereby cooling the planet for months or even y
