Ash propelled that high (into the stratosphere) could cool the planet.
Sumatra’s incredibly active Sinabung Volcano exploded in spectacular fashion to 40,000 feet (12.2 km) again yesterday, March 2, sending volcanic ash high into the atmosphere and depositing ash on nearby villages.
Activity at the volcano in North Sumatra province increased over the past week, with authorities recording 13 times when it released ash clouds.
Dramatic video from the Volcanological Survey of Indonesia shows the plume of ash reaching high into the sky.
Particulates ejected to altitudes above 32,800 feet (10 km) –and into the stratosphere– have a direct cooling effect on the planet.
According to volcano.si.edu, Sinabung woke in 2010 after centuries of quiescence. However, that 2010 phase turned out to be a mere precursor to the long and powerful episode which began on Sept 5, 2013 and ran until Jul 15, 2018 which qualified as a VEI 4.
The 2,600-metre (8,530-foot) Sinabung had been inactive for four centuries before the 2010 eruptedion, killing two people. Another eruption in 2014 killed 17 people, while seven died in a 2016 eruption.
A year later Mount Sinabung fired back into life, in May, 2019.
This latest eruption (beginning on March 2) ranks as one of the largest in years, rivaling the 55,000 footer of June 9, 2020.
Northern Sumatra is part of Indonesia, which consists of 17,500 islands and is prone to volcanic eruptions and earthquakes because of its location within the so-called “Ring of Fire” — a series of fault lines stretching from the Western Hemisphere through Japan and Southeast Asia.
With an increase in above-water volcanic activity, is underwater volcanic activity also increasing? If so, that would heat the oceans. Those warmer waters would lead to more evaporation and ever more moisture rising into the skies.
More moisture rising into the colder skies, skies cooled by the above-ground eruptions, leads to more snow, and – voila! – instantaneous ice age.
Warmer water and colder skies – a recipe for disaster.

“Mother Nature has been trying to tell us something for a long, long time but, sadly, few have listened,” says Winston. “Perhaps she is getting ready to hit us over the head with a rock? Bet we don’t even listen then!”
