Hi Tony,
re your questions

1) Al Gore didnt prove it and from what i have heard he was possibly using the 420000yr Vostok core as opposed the more recently drilled EPICA core which extends back to ~600000 and the relationship between T and CO2 is more tightly contstrained. And yes it shows a roughly 800yr lag for CO2. There is a fairly decent theory behind the lag (positive feedback). It makes sense to me. If it doesn't seem plausible to you Tony I'd be interested to hear your opinion on what might have caused CO2 to rapidly increase after a temperature rise (I genuinely am interested)

2) positive feedbacks is a plausible explanation. Aliens I'm not sure about though.

3) Wrong of course and we all know that. Holcene thermal maximum occured around 4000 years ago.

4) Again wrong. Around 10,000 years ago the earth was rapidly coming out of a glacial period.

5) Yeh I'd agree with that. But perhaps around 0.6-0.7 since 1945 or since 1980. Around 1degree C in the nothern hemisphere.

6) human CO2 or natural CO2, more or less the same. There is other evidence of CO2-Temperature relationship. Paleocene Eocene Thermal Maximum event.
Greenhouse gas/greenhouse effect is what keeps the Earth at a more or less stable and livable 14degrees C.
Venus has very high atmospheric CO2 content, large greenhouse effect and the surface is much hotter than the Earth, even taking into account increased incoming solar radiation due to being closer to the Sun.

7) Sure they are. Plate tectonics don't play a major role on decadal or century timeframes. Solar variation (11yr cycle) is estimated to effect Earths temperature by 0.1degrees C or so and during the Maunder minimum by around 1degrees C ( I think 1deg C). Orbital variations have minimal influence over decadal timeframes. etc, etc

Tony we are not all bloody alarmists. Get over it. We simply have a different opinion to you regarding CO2 (human induced or natural). Neither of us have provided conclusive evidence and I doubt any of us here will.

Anyway like someone just posted moving to a low carbon world, more sustainable energy sources is the way to go anyway. And its not just the hippies/greenies/alarmists that think this is a good thing.
Helen Ridout, from the Australia Industry Group has publicly stated we should be moving to a low carbon, sustainable energy economy. But then she is just sucking up to Rudd i guess.
Wouldn't it be great if we could supply third world villages, who have no access to electricity, cheap solar/wind energy for electricity and water pumps, health and education. Wouldnt it be easier to have on-site sustainable power generation (solar/wind) than connect every small village in India or Africa to the electricity grid).
On a recent trip to the Bolivian Amazon we lived in a remote village for a couple of weeks. No power at all. You should see the excitement on their faces when they talk about the solar panels that are being installed and that maybe one day they might all be able to turn a light on in their house for maybe an hour a night.The chance of them ever having access to any other forms of electricity other than their small/broken and hugely expensive diesle generator is exactly zero, no chance.

So actually I don't give a crap if you are right Tony. If the billions we have wasted, as you say, actually drives more sustainable energy forms I'm all for it.

Sorry about any spelling/grammer mistakes.
