You seem to have missed a rather important bit of information I offered.

ive reread both your posts. what bit are you referring to?

im trying to work out what Hall was talking about. it sounded like he was describing the ecliptic but that doesnt make sence, so im trying to clarify.

what i should of asked, is if he was referring to the inclination of orbit relative to the sun's equator

The link to the bit that clearly shows Lucie Green is a woman (and other information about Lucie). This leads me to suspect you have not fully explored my post and only "cherry picked" for your response.
Hey, there is nothing wrong with that but, knowing you have achieved certain academic achievements, I would have thought you would have been interested in the academic achievements of someone whose opinion you appear to be dismissing.

i only read what you posted, i didnt look at the link.
and i wouldnt say im dismissing it. im keeping an open mind that it might not be the only information/theory available.
120 years ago physicists thought we knew everything about physics. newtonian mechanics was the final answer. we now know better.

Now, that makes more sense!!!!:)

Yes, an even SOME of Einsteins theories (brilliant they may be) are starting to get a wobble up. But science is progressing all the time.:)

Any chance of this cooling happening soon?, Bob

I however didn't study stellar evolution at uni, so I'm happy to be corrected.

I would think only a small percentage of the sun's output reaches the earth. Say for arguments sake that was 1% (you should enlighten us as to the true amount). Then if the sun's output was reduced by 1% the reduction seen on earth would be 0.001%, would it not?

in the distant past when earth was warming up, co2 levels only rose hundreds of years AFTER the warming, not before. this might indicate that the greenhouse effect doesnt work like we thought it did. what i understand its not conclusive though, it just points to something not being correct in the current greenhouse theory.

Not necessarily so! I think your logic is flawed.

The conclusions I would draw are, from only considering what you have posted:

1. the rise in temperature in that distant past event you cite, had some cause possibly not related to CO2 levels.

2. that particular pre-historical event doesn't make warming due to increased levels of CO2 unlikely. I don't see how you conclude that it does, or the current theory incorrect.

No if the Sun output reduced by 1% we would get 1% less than previously,

I think the point is there are many variables to Global Warming or Cooling, C02, Water vapor, Sun activity, axis of the earth, volcanic activity, (e.g Krakatoa) so its not cut and dried to say CO2 is the culprit, although it is probably the biggest induced human factor, although i would not discount RFC's (?) and the damage they did.

That 1% reduction in the Sun's output is the total output that is radiated into space for 360 degrees around the Sun. The Earth does not completely surround the Sun in only occupies a small quadrant. Therefore the reduced amount it would receive would be far less than a 1% reduction as suggested by an earlier poster.:)
