Global Cooling Part 2

Welcome to part 2 of global cooling...
We shall now introduce one factor of
the world that might cause global cooling
and that thing is super hot and you can die
touching it and what does that make you think
of?
VOLCANOES.
And you must be thinking, how could something this hot
cause the world to go into the next ice age and make us all die?
The types of volcanic eruptions and associated activity: phreatic eruptions (steam-generated eruptions), explosive eruption of high-silica lava (e.g., rhyolite), effusive eruption of low-silica lava (e.g., basalt), pyroclastic flows, lahars (debris flow) and carbon dioxide emission. All of these activities can pose a hazard to humans. Earthquakes, hot springs, fumaroles, mud pots and geysers often accompany volcanic activity.
Large, explosive volcanic eruptions inject water vapor (H₂O), carbon dioxide (CO₂), sulfur dioxide (SO₂), hydrogen chloride (HCl), hydrogen fluoride (HF) and ash (pulverized rock and pumice) into the stratosphere to heights of 16–32 kilometres (10–20 mi) above the Earth's surface. The most significant impacts from these injections come from the conversion of sulfur dioxide to sulfuric acid (H₂SO₄), which condenses rapidly in the stratosphere to form fine sulfate aerosols. The aerosols increase the Earth's albedo—its reflection of radiation from the Sun back into space - and thus cool the Earth's lower atmosphere or troposphere; however, they also absorb heat radiated up from the Earth, thereby warming the stratosphere. Several eruptions during the past century have caused a decline in the average temperature at the Earth's surface of up to half a degree (Fahrenheit scale) for periods of one to three years...
This will affect the whole earth as the sulfuric acid in the stratosphere spreads around the globe
as the wind from the southern and northern hemisphere spread it around...
So the badly affected countries will have food shortage and will cause an economic depression...
but scientist say that this is still not enough to make the earth to plunge into another ice age...
WHAT WILL?
It will be explained in the next topic...
