Volcanic eruptions spew sulfur dioxide into the atmosphere, which tends to block incoming sunlight, sometimes cooling the planet for several years. This cooling leads to a decrease in the heat stored in the ocean and thus in the rate of ocean thermal expansion and sea level rise. These effects can be seen in simulations that include variations in volcanic aerosol.
