from the paper in Nature, "Volcanic dust veils from sixth century tree-ring isotopes linked to reduced irradiance, primary production and human health":
Figure 1 -- Sampling sites. Carbon isotope data of this study was collected from (a) upland and (b) riparian settings where the subfossil specimens are preserved in the lacustrine sediment and subaerially, respectively. Map showing the sampling sites for this study (star) (c). Photos by Hannu Herva (a) and Samuli Helama (b). The map was created by OriginPro 2017 SR1 software (http://www.originlab.com/).

"...the eruptions covered the
sun Erf for a long time..."
Science?

"The new study tracks the correlation of carbon isotope variation and volcanic eruptions from the 19th century until recent years, and shows the dramatic reduction in available sunlight in 536 as well as between 541 and 544 CE."
How does this make sense?

Any article that uses “CE” as a date specifier I skip. It means the writer is a left wing hack, count on it.

Have they identified which volcanoes erupted?

"Volcanic dust ... linked to reduced irradiance, primary production and human health"
Not a very novel finding.

According to my old notes, the famine hits Constantinople in 536, then the plague in 541 (as bad as the Black Death of 1347, though it doesn’t get the same cachet in legend). Just as the plague begins to recede, the major earthquake of 557 destroys much of the city, and two years later, while the rubble is still being removed, the Huns (under Zabergan, not Attila) show up, but miraculously Belisarius is able to keep them from invading the city. And we think we have it bad.

Regarding “CE”;
Atheists pretending they can use “science” to explain a godless creation.

So the earth puts some ash up in the air, and everything falls apart?
Well, lets take those cigarettes away from the earth, then.
Lets put one of those nicotine patches on the earth.
Say, over Iran.

“CE” is based on the birth of the baby JESUS. Whenever you see it think of the baby JESUS. I also skip these articles.

Any or all of that can recur in our time. I suspect it will.

here’s part of a list I compiled for other purposes showing the volcanic eruptions from 0AD to 900AD and their VEI (St Hellens was VEI 5; each number greater is 10 times the previous expressivity). Each of those listed are 10 times greater than St Hellens.
0 A.D. - Carbon-14 Spike
50 A.D. - Ambrym, Vanuatu, Fiji Islands Erupts
Volcanic Explosivity Index (VEI) = 6+
60 A.D. - Churchill, Eastern Alaska Erupts
Volcanic Explosivity Index (VEI) = 6
180 A.D. - Taupo, New Zealand Erupts
Volcanic Explosivity Index (VEI) = 6+
240 A.D. - Ksudach, Kamchatka Peninsula, Russia Erupts
Volcanic Explosivity Index (VEI) = 6
426 A.D. - Dark Ages (Middle Ages) Begins
450 A.D. - Ilopango, El Salvador Erupts
Volcanic Explosivity Index (VEI) = 6
536 A.D. - Rabaul, Papua New Guinea Erupts
300 million tons of aerosols.
Volcanic Explosivity Index (VEI) = 6.
700 A.D. - Churchill, Eastern Alaska Erupts
Volcanic Explosivity Index (VEI) = 6
800 A.D. - 1300 A.D. - The Medieval Warm Period
