The eruption caused a global climate change known as the "volcanic winter".

The harsh climatic conditions that accompanied the volcanic winter may have placed pressure on humans to cooperate with each other.

Following massive Plinian eruptions, temperatures may decrease to cause volcanic winters.

The related catastrophe hypothesis holds that this event caused a global volcanic winter of 6-10 years and possibly a 1,000-year-long cooling episode.

A volcanic winter is a climate cooling caused by an extremely large volcanic eruption.

Recent reports have shown that the planet may be due for another series of cataclysmic eruptions, which could cause another devastating volcanic winter.

Historically, so-called volcanic winters have caused catastrophic famines.

The character reappears with Alkhema, and together they plan to create a "volcanic winter" by placing bombs underneath several volcanoes.

I could imagine the toxicity of the eruptions and coal killing much life in rapid successions, followed by a volcanic winter that kills even more.

This has been dubbed a "volcanic winter", similar to a nuclear winter, due to the overall decrease and abysmal farming conditions (Oppenheimer 2003).

The resulting explosive volcanism probably ejected large amounts of dust and debris into the stratosphere causing major cooling (see volcanic winter).

For example, a 10-year volcanic winter triggered by the eruption could have largely destroyed the food sources of humans and caused a severe reduction in population sizes.

The topic in the background is an overview of the VEI and sulfur dioxide emission/ Volcanic winter relationship.

One proposed volcanic winter happened c. 70,000 years ago following the supereruption of Lake Toba on Sumatra island in Indonesia.

At the age of 13, Liebig lived through the year without a summer, when the majority of food-crops in the northern hemisphere were destroyed by a volcanic winter.

The first volcanic winter in 1816, known as the Year Without a Summer, affected the Canadian province of Newfoundland and Labrador.

Volcanic winters are caused by volcanic ash and droplets of sulfuric acid obscuring the sun's light, usually after a volcanic eruption.

- Black carbon particles produced from nuclear fire storms are smaller than sulfate particles produced by volcanic eruptions (which can bring about volcanic winter).

Some scientists correlate this event with a volcanic winter, possibly due to the Minoan eruption of Thera circa 1628 BC.

They realize that if the fault crosses with the caldera it would erupt, expeling 2,000,000 ton of ash into the atmosphere, killing millions immediately and causing a Volcanic winter.

The volcanic winters were also felt in the Maritime provinces, which includes Nova Scotia, New Brunswick and Prince Edward Island.

Similar climatic effects can be caused by comets or an asteroid impact, also sometimes termed an impact winter, or by a supervolcano eruption, known as a volcanic winter.

This, combined with the fact that most human differentiations abruptly occurred at that same period, is a probable case of bottleneck linked to volcanic winters (see Toba catastrophe theory).

A geological event such as massive flood basalt, volcanism, or the eruption of a supervolcano leading to the so called Volcanic Winter (Similar to a Nuclear Winter).

The eruption of Toba led to a volcanic winter with a worldwide decline in temperatures between 3-5 degrees C, and up to 15 degrees C in higher latitudes.
