Indeed, the era
between 65,000 and 25,000 years ago, toward the end of the Paleolithic, was a time of major
volcanic eruptions, along with extremes of climate that included rapid shifts in temperature accompanied
by alternately creeping and contracting glaciers across many regions of Eurasia.
By comparing volcanic activity to records of social unrest, the researchers found a correlation between the two that was too closely matched to dismiss: «In years influenced by volcanic eruptions, Nile flooding was generally diminished, leading to social stress that could trigger unrest and have other political and economic consequences,» Manning sai

The largest
eruption of the 20th Century inspired a large amount of research on the connection
between volcanic eruptions and the Earth's atmosphere in the 12 years since that
eruption, as exemplified
by the chapters in this book.
McGuire conducted a study that was published in the journal Nature in 1997 that looked at the connection
between the change in the rate of sea level rise and
volcanic activity in the Mediterranean for the past 80,000 years and found that when sea level rose quickly, more
volcanic eruptions occurred, increasing
by a whopping 300 percent.
It actually ended up reinforcing a controversial hypothesis that had been put forward more than two decades ago
by a scientist who had argued there was a relationship
between tropical
volcanic eruptions and El Nino events.
Then you actually need to be able to say something about how climate change will influence El Nino, and
by studying the past relationship
between El Nino and natural factors like
volcanic eruptions we could potentially better inform our understanding of how the El Nino phenomenon will respond to climate change.
ABSTRACT From 1950 to 1987 a strong relationship existed
between the El Nino Southern Oscillation (ENSO) and HadCRUT4 global average temperature anomaly, interrupted occasionally
by volcanic eruptions.
How the seasonal weather changes at a particular climate depends on ocean currents so you can have correlation
between volcanic eruptions and «global climate» but one is not necessarily affected
by the other.
The difference
between 0.5 to 0.6 and 0.84 may be largely due to GCMs often exhibiting too strong a response to
volcanic aerosols and / or a tendency for
volcanic eruptions to be closely followed
by El Nino events.
