A shame my dad isn't on Usenet - he could raise his hand on this one. He used to simulate the conditions in the Sun in 1960s/1970s at Culham Laboratory in the Theta Pinch experiment that ran there at the time (before JET was there).
A good job we didn't go for wide scale tidal, or the moon would have floated away...
Those nothing to do with the sun "dimming". To do with the Earths orbit, precession and axial tilt etc. Also been known about for a hundred years. We should actually be cooling down now but we aren't.
But significant cooling isn't going to happen anyway.
The climate is slowly recovering from the Little Ice Age (LIA), with global temperatures increasing by 0.5°C/century. The rise in global temperatures 1975-2000 parallels the similar rises 1910-1945 and
1850-1880, each rise being followed by a pause or slight decline, and nothing to do with CO2. It has been suggested that these rise - pause sequences are the result of the linear recovery from the LIA coupled to a multi-decadal oscillation of period 50-60 years such as the Pacific Decadal Oscillation, which would give the observed temperature behaviour. See Akasofu in the journal 'Natural Science':"Abstract: The rise in global average temperature over the last century has halted since roughly the year 2000, despite the fact that the release of CO2 into the atmosphere is still increasing. It is suggested here that this interruption has been caused by the suspension of the near linear (+ 0.5 °C/100 years or 0.05 °C/10 years) temperature increase over the last two centuries, due to recovery from the Little Ice Age, by a superposed multi-decadal oscillation of a 0.2 °C amplitude and a 50~60 year period, which reached its positive peak in about the year 2000?a halting similar to those that occurred around
1880 and 1940. Because both the near linear change and the multi-decadal oscillation are likely to be natural changes (the recovery from the Little Ice Age (LIA) and an oscillation related to the Pacific Decadal Oscillation (PDO), respectively), they must be carefully subtracted from temperature data before estimating the effects of CO2."Akasofu is no mean cookie when it comes to climatology

Far too clever for me!
Don't confuse them with facts, their mind is made up...
Yes, that's him.
And me!
He's still working (although retired), fitting the observations of the sun by GOLF (on SOHO) to G-modes of the sun, using mathematical models which run for days on a computer, and publishing papers.
No, we fully understand how stars work.
