Not at all, I'm saying the volcanic activity in that pic does not correlate with temp. That's it.

Thanks Set for moving the thread.

In 1991 the Earth cooled after a volcanic eruption
but yes - you are right - there is no major correlation.

The question is -
what has caused these hot & cold periods?

May I say that it appears it has nothing to do with CO2?

You may say what you like Bobby. Grin

What i found interesting was the 1100BC thing. I'm a bit of a bronze age buff. The collapse of all but one(Egypt) of the bronze age empires in a generation or two around 1187bc is of immense interest to me.

But the Bronze age civilisations flourished during most
of the warm period & so did the Romans & the Vikings
in the warm periods that came afterwards.

These warm periods have not been well explained.
Maybe it's due to the orbit of the Earth or
the fact that our Sun is a variable star?

I'm guessing that a grand solar minimum + high volcanic activity
will plunge us into a temporary mini ice age.
There is evidence that it started already - just 2 years ago.

No they didn't Bobby. They died out and there was a dark age. The Mycenaean Greeks went down(Homeric stories are from this time, Troy), the Hittites went down, the Cypriots the Canaanites and Minoans went down. The Romans used Iron as did the Vikings.

The Greeks forgot how to write, could not build the big poo they did, there was a 400 year dark age. The Homeric stories were handed down via story until about 800 BC when they started to come out of the abyss.

Why then does the pic have climate from the past with volcanic activity that does not correlate with the Earth's temperature variations? Should I move it back out from here as it doesn't fit our climate today?

There is a little bit of correlation in parts - look at Krakatoa.
No - please leave it here where it belongs.

There seems to be a cyclic pattern.

From the image there does seem to be a pattern but it is not related to the volcanic activity in the pic. That's the point I'm trying to make.

Is it not only about the climate today anymore?

Dear Setanta,
we are trying to predict the climate today by
understanding the past history.
Is there anything we can learn from our history?

The world doesn't need prophets.

If your pic is anything to go by you can rule out volcanoes. You can learn from the end of the bronze age that you cannot control what happens, systemic forces conspire and no matter how big you are you may well fall. That's the lesson of history and why none of the bronze age civs made it besides a crippled Egypt.

Have another look at Krakatoa in 535.
There is certainly a cold period after that.

see:

http://customers.hbci.com/~wenonah/history/535ad.htm

535 AD

The nobles were returning from the middle east "HOLY WARS".
Pope John II died.
There were days of darkness.
The plague swept around the world three times in about ten years.
There were seven years of crop failures.
Nations changed their religions.
Empires Fell.
In places great drought destroyed the land.
In other places floods brought chaos.
Tree rings didn't show normal growth for fifteen years.

I'm not going to look but choosing one does not sit well against the "evidence" in the pic.
