" The latest VEI 7 event, at Tambora, Indonesia, in CE 1815, was at the low end of VEI 7 eruptions." I didn't need to know that; Tambora is closer than NK.

They could reduce their temperature by dropping large quantities of ice on them.... ahhhh errrm

Abstract The Atlantic multidecadal oscillation (AMO) is a 60–70 year pattern of sea-surface temperature (SST) variability in the North Atlantic commonly ascribed to internal ocean dynamics and changes in northward heat transport. Recent modeling studies, however, suggest that SSTs fluctuate primarily in response to major volcanic eruptions and changes in atmospheric circulation. Here, we utilize historical SST, atmospheric reanalysis, and stratospheric aerosol optical depth data to examine the basic evidence supporting a volcanic link. We find that cool intervals across the North Atlantic coincide with two distinct episodes of explosive volcanic activity (1880s–1920s and 1960s–1990s), where key eruptions include 1883 Krakatau, 1902 Santa María, 1912 Novarupta, 1963 Agung, 1982 El Chichón, and 1991 Pinatubo. Cool SST patterns develop in association with an increased prevalence of North Atlantic Oscillation (NAO)+ atmospheric patterns caused by stratospheric aerosol loading and a steepened poleward temperature gradient. NAO+ patterns promote wind-driven advection, evaporative cooling, and increased albedo from enhanced Saharan dust transport and anthropogenic aerosols. SSTs across the subpolar gyre are regulated by strength of low pressure near Iceland and the associated wind-driven advection of cold surface water from the Labrador Sea. This is contrary to an interpretation that subpolar SSTs are driven by changes in ocean overturning circulation. We also find that North Pacific and global mean SST declines can be readily associated with the same volcanic triggers that affect the North Atlantic. Thus, external forcing from volcanic aerosols appears to underpin multi-decade SST variability observed in the historical record. Something to get your teeth into.

Like any mention at all of the great "glow plug" in the sky? "Shakers" just congregate cyclically of their own volition? Pele would be pleased.

I don't think the author's hypothesis is mutually exclusive to the linkage of our star's role in Earth's geologic activity.

You know all those papers that calculate human impact on CO2 levels by quantifying the amount of 14C compared to 12C as that can _only_ come from human use of fossil fuels, and the rate of reabsorption, the life of CO2 in the atmosphere is also based on the amount of 144C CO2 that remains in the atmosphere after quantified fossil fuel burning - so it is claimed it will be there for thousands of years Well that has been shown to be about as useful as the tree rings of the god tree in Yamal... "Discovery Of Massive Volcanic CO2 Emissions Puts Damper On Global Warming Theory
Recent research shows that the volume of volcanic CO2 currently being emitted into Earth’s atmosphere is far greater than previously calculated, challenging the validity of the man-made global warming theory....
Especially knowing that volcanic activity varies greatly from area to area, volcano to volcano, and through time. Utilizing just 0.001 percent (10/901,500) of Earth’s volcanic features to calculate volcanic CO2 emissions does not inspire confidence in the resulting value.
Non-Erupting Volcanoes Can Emit Massive Amounts of CO2 into Earth’s Atmosphere
Recent geological research by the University of Leeds and others proves that non-erupting volcanoes can emit massive amounts of CO2 into Earth’s atmosphere and oceans. The Gerlach calculation and all follow-up calculations utilized volcanic CO2 rates from actively erupting volcanoes.
Lost in the numerous recent media articles concerning the argument of when, or if Iceland’s Katla Volcano will erupt is the discovery that this non-erupting subglacial volcano is currently emitting staggering amounts of CO2 into Earth’s atmosphere!....
......we show that Katla, a highly hazardous subglacial volcano which last erupted 100 years ago, is one of the largest volcanic sources of CO2 on Earth, releasing up to 5% of total global volcanic emissions...."climatechangedispatch.com/massive-volcano-emissions-warming/

This graph is actually of the diffusion of CO2 in ice as a function of pressure. After a certain depth in the ice the pressure is such that the ice ceases to be impermeable to CO2 which then dissolves and diffuses and disperses through the ice reducing the CO2 content of any 'bubbles' that remain. Now use the figures to disprove my hypothesis
