P. 11, penultimate paragraph, first line:
Change “hen” to “when”

Wonder how long it will take for this solar effect to be noticed and ‘quashed’ by Icarus? No doubt, the solar poloidal field will be found to vary at 1 AU by some insignificant amount and the earth effect therefore negligible.

As Kuhn pointed out, paradigms are notoriously resistant to contradiction and change in the face of contravening evidence.

“OT, sorry, but Monckton’s new paper on the HS and the MWP is IMHO well worth a write-up from you. Good thing is, he balances excellent science (MWP) and vital politics (the HS story) very well. A fellow UK citizen I can be proud of.”

I agree.

BTW, I sent a comment to US Pres candidate McCain that he should reconsider his cap and trade position and that, recognizing the political risk, he should form an independent scientific commission to study the issue as a due-diligence action, to make sure the investment will be sound. This is probably the only way out for a politician who has committed to the A-CO2-GW action.

If this is true and I haven’t looked at any of the links that might have been provided above, it seems that solar activity might be a proxy. The actual cause might be planetary orbit alignment changes inducing gravitational stressing of the Earth’s crust and/or magma flow acceleration/decelerations. The orbit changes would also influence circulation patterns in the Sun which changes solar activity.

I did read this as a proposed theory somewhere that had some physics analysis to support it.

Not forgetting the 8 month ‘Laki event’ in 1783, which is also well documented. Yet another ‘Year without a Summer’. Not quite as dramatic as Tambora, but with similar effects on the Weather.

Wonder if the historical record bears out the ‘Solar Minima a time of greater volcanic activity’ postulate?

“Is there any link between solar behaviour and incidence of vulcanism?

Yes there is!

Ugh. I sure hope this paper is wrong.

Dalton Minimum + Tambora = “Year Without a Summer.”

Nobody knows how many people died as a result (record keeping was still poor).

There were anecdotal reports of people dying from eating rotted horse flesh.

In our time, the vast majority of us don’t even have access to fresh horse flesh!

You can always read this theory by Ambrose concerning Toba in Sumatera. (I know it’s wikiganda but it will do)

Obama is talking about creating a Clean Energy Corps. I guess it’s like the Peace Corps, except instead of drilling water wells in third world countries, they’ll show up at our homes and businesses to “help” us to clean up our terrible CO2 emissions. Those idealistic college kids will straighten us out.

Chairman Mao had the same ideas in the sixties. He created the red guard. Sent them out to re educate their elders. After they finished that task, Mao sent them out to Mongolia to get them out of the way.(And try and undo the damage that they had created)
