Large equatorial eruptions that carry ash into the medium to higher altitudes are what cause cooling. The hadley cells spread the ash across the equatorial region as their currents gather the ash at lower altitudes and distribute it at the higher altitudes. Conversely, the direction of circulation of mid latitude currents tend to keep the ash located at their respective latitudes.
Equatorial eruptions tend to spread the ash across an area where the sun creates the most heat, resulting in more significant cooling.
Mid latitude eruptions tend to keep the ash localized across an area of less solar heating. The mid latitude regions don't get as much heat from the sun, meaning less cooling.
This is what happened in the 1800s with the year without a summer. That volcano is right on the equator.
Has an eruption recently happened at the equatorial region? Hmmmm.
Sulfur Dioxide in the STRATOSPHERE -- not a well-understood layer, with far less predictable cycles than the troposphere. The chemical analysis is the usual spin for defenders of global warming: the volcano cooled the planet in the short-term but *warmed* it in the long-term due to SO2 and CO2. These analyses almost always ignore the obvious physical effects of particulate matter blocking sunlight -- basically what millions of people saw and suffered through!
Another issue that is glossed over is the 1 degree Celsius cooling which caused snow in June 1816 in New England. How could a single degree of cooling as "global average" cause such a big effect in entire regions (Europe and China were other areas)? Are they averaging 24-hour temperatures? Sea surface and land surface?
And finally the converse: if a 1 degree fall in "global temperature" caused such incredible effects in 1816 (and a few subsequent years), why aren't we seeing massive changes from the 1 degree rise that has been measured in recent years? There are clearly multiple variables that are resonating in some situations and not others.
Law of unintended consequences - Stop and start the world economy for two years. Stop and start emissions and see what effect that has on the climate.

Look up iceagefarmer.com he's been talking about this for years. We're currently in a Grand Solar Minimum, a mini ice age.
Great article as always. Spaceweathernews.com has a lot of sun/earth related weather info you might find interesting.

And after 1816, nothing interesting happened in Ely ever again.
