What has of interest? The question of the extinction of Neanderthal.

We all know that they disappeared more or less around 40,000 years ago.
Among the common topics of Neanderthal, they commented a reason to explain
the disappearance around this period. The postulate, someone did, the
explosion of a supervolcano that erupted in Italy, in the Phlegraean Fields

https://en.wikipedia.org/wiki/Phlegraean_Fields

Campi Flegrei [ˈkampi fleˈɡrɛi]; from Greek phlego φλέγω, "to burn")[2][citation needed] are a large volcanic area situated to the west of Naples,
Italy. It was declared a regional park in 2003. Lying mostly underwater, the
area of the caldera comprises 24 craters and volcanic edifices. Hydrothermal
activity can be observed at Lucrino, Agnano and the town of Pozzuoli. There are
also effusive gaseous manifestations in the Solfatara crater, the mythological
home of the Roman god of fire, Vulcan. This area is monitored by the Vesuvius
Observatory.[3]

The First Phlegraean Period. It is thought that the eruption of the
Archiflegreo volcano occurred about 39,280 ± 110 years (older estimate
~37,000 years) ago, erupting about 200 km3 (48 cu mi) of magma (500 km3
(120 cu mi) bulk volume)[5] to produce the Campanian Ignimbrite.[6] Its
Volcanic Explosivity Index (VEI) was 7. "The dating of the Campanian
Ignimbrite Eruption (CI) to ~37,000 calendar years B.P. draws attention
to the coincidence of this volcanic catastrophe and the suite of coeval,
Late Pleistocene biocultural changes that occurred within and outside
the Mediterranean region. These included the Middle to Upper Paleolithic
cultural transition and the replacement of Neanderthal populations by
anatomically modern Homo sapiens, a subject of sustained debate.[7] No
less than 150 km3 of magma were extruded in the CI eruption, the signal
of which can be detected in Greenland ice cores. As widespread discontinuities
in archaeological sequences are observed at or following the CI event,
a significant interference with ongoing human processes in Mediterranean
Europe is hypothesized." [8] New research led by Liubov Vitalievna Golovanova
and Vladimir Borisovich Doronichev of the ANO Laboratory of Prehistory in
St. Petersburg, Russia, supports the hypothesis that these eruptions drove
Neanderthals to extinction and cleared the way for modern humans to thrive
in Europe and Asia.[9] The area is characterised by banks of piperno (it)
and pipernoid grey tuff at Camaldoli hill, like in the northern and western
ridge of Mount Cumae; other referable deep products are those found at Monte
di Procida, recognizable in the cliffs of its coast.

end of cite/

well, some collaborator in this video presented the case of this volcano
to explain the extinction of the Neanderthals. The explosion was so powerful
that a distance of 1100 km in Romania, the fine ashes of the volcano presented
one meter of thickness. More or less this explains the graphic NGRIP we can
observe for this period of time a serious drop in temperature lasting a few thousand years. But is almost imperceptible in the curve of EPICA. This volcano would had caused the most effects on the Norther Hemisphere.

I had been collecting these stamps of temperature and others it can be seen
for this period the putative effect of the Achiphlegreo volcano that is considered to have occurred about 39,280 ± 110 years (older estimate
~37,000 years) ago. In one of the graphic on Antarctica Dome C it shows
an older data, but the graphic does not look of high resolution. I need to
check more graphics to be sure of what I am saying.
