«Volcanic aerosols in the stratosphere absorb infrared radiation, thereby heating up the stratosphere, and changing the wind conditions subsequently,» said Dr. Matthew Toohey, atmospheric scientist at GEOMAR Helmholtz Centre for Ocean Research Kiel.

The effect also illustrates one proposal for so - called geoengineering — the deliberate, large - scale manipulation of the planetary environment — that would use various means to create such sulfuric acid aerosols in the stratosphere to reflect sunlight and thereby hopefully forestall catastrophic climate change.

Scientists have proposed that what some call «the pause» could be the result of a number of factors, including heat storage in deep ocean waters to unexpectedly high amounts of aerosols in the stratosphere helping deflect solar rays back into space.

The failure to actually reduce global emissions has meant that all possibilities are now on the table, including some that sound like premises from a science - fiction novel: Humans could sequester carbon dioxide by removing it from the air through technologies that mimic trees, or we could spray water droplets in the lower atmosphere to reflect light and heat back to space, or we could seed sulfur aerosols in the stratosphere to do the same.

Sulphate aerosols in the stratosphere (which were the main topic of this piece and these Climate Feedback posts) and mirrors / refractors in space (also in that piece, and in this paper by Roger Angel) both have the potential to provide as much by way of negative forcing as a doubling of CO2 provides by way of positive forcing.

For instance, given the physics of sulphate aerosols in the stratosphere (short wave reflectors, long wave absorbers), it would be surprising if putting in the aerosols seen during the Pinatubo eruption did not reduce the planetary temperature while warming the stratosphere in the model.

This can be done so through geoengineering (e.g., aerosols in the stratosphere or mirrors in space).
