The whole idea of a global climate is a contradiction in terms. There are millions of climates all over the planet. One thing we know is that heart's active geology makes the ocean more alkaline, which is why the average ocean pH is about 8.3, give or take a wide margin of error. It's merely a matter of scale. In a river, every eddy is a micro-climate. Change the flow and every eddy is affected, in different but related ways. Climate is much more complex than a river, but it may scale in similar ways. The "Great Believers" say it's all a bottom-up process. The termites control the planet. Well the ants and termites generate more CO 2 than all human activity

A single high VEI event would not have an 18 month effect on visible light. It sounds more like a continual high VEI eruption that lasted for at least (from the times above) 9 months. There must be some geographic evidence for that type of eruption. Anyone been able to find that kind of volcano or even a large caldera like Yellowstone. An almost one year eruption that could darken the skies will not be a simple volcano. Theories abound. Here’s one: www.smithsonianmag.com/science-nature/sixth-century-misery-tied-not-one-two-volcanic-eruptions-180955858/Others believe Krakatoa was the culprit. I think it was very, very low CO2 🤓 The Lake Ilopango crater has a surface area of 28 sq. miles. That would be impressive in stages or most at once.

Discovering new thermal areas in Yellowstone's dynamic landscape!
Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from R. Greg Vaughan, research scientist with the U.S. Geological Survey.
Yellowstone's thermal areas are the surface expression of the deeper magmatic system, and they are always changing. They heat up, they cool down, and they can move around. A recent spectacular example was the September 2018 emergence of a new thermal feature and eruption of the long-dormant Ear Spring in the Upper Geyser Basin, near Old Faithful. Even more impressive was the expansion of heated ground in the Back Basin of the Norris Geyser Basin in 2003. These sorts of changes are part of the normal life cycles of thermal areas in Yellowstone National Park.
Recently, we have discovered another phenomenal example of thermal change—the emergence of an entirely new thermal area, which has taken place over the past 20 years!"volcanoes.usgs.gov/volcanoes/yellowstone/article_home.html?vaid=160

"LIMA, Peru — A large earthquake with a preliminary magnitude of 8.0 struck the Amazon jungle in north-central Peru early Sunday, the U.S. Geological survey reported.
The quake, at a moderate depth of 110 kilometers (68 miles) struck at 2:41 a.m., 80 kilometers (50 miles) southeast of the village of Lagunas and 158 kilometers (98 miles) east-northeast of the larger town of Yurimaguas.
There were no immediate reports of casualties, although some buildings collapsed and power cuts were reported in a number of cities. Earthquakes that are close to the surface generally cause more destruction."www.msn.com/en-us/news/world/magnitude-8-earthquake-strikes-amazon-jungle-in-peru/ar-AABW3gz?ocid=spartandhp

Marta's brother said he distinctly felt it in Bogota. That is ~700+ miles north.

I was just about to post this. You beat me to it Walnut! I always wondered how they decide a volcano is extinct.

Hey bary!! "A swarm of 1,000 earthquakes hit Southern California — how nervous should we be?
The seismic storm that unleashed more than 1,000 small earthquakes in San Bernardino and Riverside counties these last three weeks elicited what has become a typical reaction in quake country. To some, the “swarmageddon” 40 miles east of downtown Los Angeles brought fear that a bigger threat was coming. To others, as long as they didn’t feel a shake, it was easy to just put it out of their minds. California has small quakes all the time — a magnitude 3 every other day, on average. But not all of them act the same, and some bring more danger than others. As officials install more seismic sensors as part of the state’s early warning system, experts are getting an increasingly better look at California’s smaller earthquakes. There is general agreement that the recent swarm probably isn’t a precursor to a catastrophic quake. But other small quakes — especially ones near major fault lines like the San Andreas — are potential warnings."

"'One day a deadly earthquake will hit France'
A specialist tells The Local a big quake is due to hit south east region at some point in the future "and there will be fatalities". Locals should take heed.
“We don’t know when a big one will come, but it will and there will certainly be fatalities.”
Those were the words of French seismologist Remy Bossu from the European Mediterranean Seismological Centre (EMSC) in Paris, the day after a rare earthquake measuring 5.2 magnitude on the Richter scale hit the south east of France.
Monday night’s quake, felt in towns from Nice to Marseille and Aix-en-Provence to Grenoble, may have caused little damage but it was a stark reminder, Bossu says, that south-eastern France is in a potentially dangerous active seismic zone and the next one could do some serious damage."www.thelocal.fr/20140408/riviera-earthquake-should-be-warning-to-france
