BEZYMIANNY BLOWS TO 50,000 FEET​

Scientists have been growing increasingly concerned with the unusual behavior of volcanoes along Russia’s Kamchatka Peninsula in recent years. And this week comes a powerful uptick at Bezymianny…

A spectacular explosion occurred at 08:10 local time on Saturday, May 28. The Volcanic Ash Advisory Center (VAAC) Tokyo detected an plume that rose to an estimated 15.2km (50,000 ft) — given the extensive height, the eruption may be considered sub-plinian, according to volcanodiscovery.com (an unsteady but sustained eruption producing a column of between 10-20km).

Are volcanic eruptions associated with global cooling. Thats a big yes. Particulates that are blown into the stratosphere from a significant volcanic eruption circle the globe. They increase the albedo reading. This is of concern as they prevent solar rays from warming the earth. They are an earth cooling event. But why don't volcanoes erupt on a regular basis. The answer is they do. But the time frame is much longer than we as humans have recorded. We only think of data of a few hundred years , but these are events that happen over eons. The cause of an up tick in volcanic eruptions is strongly correlated to solar emissions. If the sun is quiet cosmic rays are able to penetrate the earth. Silicate rich magma reacts to cosmic rays causing volcanic eruptions. Which leads to global cooling.

Where are you getting the bolded info from?

I also don't agree with your statement that data from Volcanic eruptions only covers a few hundred years. We know Yellowstone's history for the past 2 million years. We know about the Toba eruption that caused a massive bottleneck in human population with a controversial estimate of only 10,000 individuals surviving worldwide. We know Campi Flegrei's history over hundreds of thousands of years and based on it's history, it is considered to be overdue for it's next major eruption. These are just a few examples of many!

But you are right, the biggest eruptions are associated with subsequent major cooling events with several years on crop failures worldwide.

Is Australia experiencing a "volcanic winter"?

The evidence suggests Hunga Tonga-Hunga Ha'apai's record-high eruption of Jan 15 is COOLING the Southern Hemisphere.
