According to model simulations, an eruption this large can pump so much
sulfur dioxide gas into the stratosphere that the atmosphere does not have the capacity to oxidize all the SO2 to sulfuric acid aerosol.
A classic case: burning fossil fuels releases
sulfur dioxide gas into the air, which then turns into sulfuric acid aerosols.
The eruption would likely spout
sulfur dioxide gas into the atmosphere where it would trigger global climate cooling.
Not exact matches
The pollution is generally a mixture of
gases — such as carbon monoxide,
sulfur dioxide and nitrogen oxides — and particulate matter, microscopic solids or droplets that can be inhaled
into the lungs.
In addition to millions of tons of ash, the force of the eruption threw 55 million tons of
sulfur -
dioxide gas more than twenty miles
into the air,
into the stratosphere.
The technique seeks to inject
sulfur into the atmosphere to reflect sunlight and offset the warming caused by carbon
dioxide and other greenhouse
gases.
Carbon
dioxide and
sulfur gases blown extremely high
into the atmosphere would have the opposite of a greenhouse effect: surface temperatures plummeting by more than 20 degrees Celsius, or about 40 degrees Fahrenheit.
The new research involves making a more accurate estimate of just how much
sulfur and carbon
dioxide gas were pumped
into our planet's atmosphere following the impact.
The protocol embraces six greenhouse
gases, carbon
dioxide, methane, nitrous oxide and industrial
gases HFCs, PFCs and
sulfur hexafluoride (SF6), that are combined in a «basket», so that individual
gases are translated
into CO2 equivalents, which are then added up to produce a single figure.
When fossil fuels are burned they produce
gasses (most significantly carbon
dioxide, but others as well, including
sulfur dioxide) which are released
into, and pollute, the atmosphere.
