Scientists warn of major volcanic eruption

"In 1815, Indonesia's Mount Tambora volcano erupted, creating unprecedented hell. The Mount Tambora eruption has since been recorded as the most powerful volcanic eruption ever recorded.

The eruption of this Indonesian volcano in the early 1800s had major consequences. A huge plume of tiny solar-reflecting particles was blown high into the atmosphere, cooling the planet. And what followed is known in world history as 'the year without a summer'.
And now a good 200 years later, scientists are warning that such a gigantic eruption might happen again.
This time, however, such an outburst would happen in a vastly changed world, a world that is not only more densely populated. Scientists fear complete climate chaos, marked by successive extreme weather phenomena, and even problems for aviation due to the volcanic eruption spewing sulfur dioxide through the troposphere." MS
