... we strongly support Delworth and Knutson's (2000) contention that this high - latitude warming
event represents primarily natural variability within the climate system, rather than being
caused primarily by external forcings, whether solar forcing alone (Thejll and Lassen, 2000) or a combination of increasing solar irradiance, increasing anthropogenic trace gases, and decreasing
volcanic aerosols.

event in terms of the global weather - so
volcanic eruption has
cause it snow in summer - big global weather change.
Two weeks ago we looked at the Triassic - Jurassic mass extinction, some 200 million years ago, that was
caused by a large climatic warming
event after the break - up of supercontinent Pangaea led to the release of enormous amounts of first [
volcanic] CO2 and then methane [from disturbed clathrates — a positive warming feedback] into the atmosphere.
I consider it as very likely that the 20 year trends will still be statistically significant also in three, five or ten years from now, unless there is some strong
volcanic explosion that blows a lot of reflecting aerosols in the stratosphere
causing a temporary temperature dip, or some other
cause the effect of which is explainable within the framework of current knowledge about the climate system, but as
event not really predictable.

volcanic events come a lowerly 6th on the ladder of
cause & effect & to study ocean temperature without finding out «why» under sea volcano eruptions happen isn't a sientific aproach in that book of mine.
For example, there are oceanic cycles like the El Niño Southern Oscillation (ENSO, comprised of El Niño and La Niña
events), an 11 - year solar cycle, and particulates released during
volcanic eruptions which
cause short - term cooling by blocking sunlight.
It kinda looks like the LIA was
caused by a series of
volcanic events and the ~ 60 year «oscillation» inspired by more
volcanic activity while the globe was recovering from the LIA.
These extinction
events can have many
causes - from meteorites, to widespread
volcanic outpourings to severe ice ages.
That could have been enough to have forced the climate change, that
caused the big Triassic die - off - the start of the
volcanic eruptions and the beginnings of the extinction
event do coincide.
A rapid input of CO2, either from burning fossil fuels or from a big
volcanic event will
cause a short term rise in atmospheric CO2, followed by a rapid sequestration.
And
volcanic event which
caused 1 C in cooling for a few years would be FAR more important.
Then throw in massive
volcanic eruptions and huge continent wide brush fires
caused by volcanoes or meteor showers (both theories I have seen in the literature) and you have many
events that could
cause climate disruption on a large scale.
Professor Plimer said climate change was
caused by natural
events such as
volcanic eruptions, the shifting of the Earth's orbit and cosmic radiation.
These are such
events as fire or smoke, lightning, windstorm or hail,
