Where did you get that graph from its not an IPCC graph is it?
Actually it's from the University of Georgia. Good Southern Baptists. Thought you'd appreciate that.
Quote:The sun is responsible for temperature here on Earth not CO2.
Gross simplification alert. The Earth's temperature is driven by heat input and output. If the output is reduced, heat accumulates resulting in higher global temperatures.
Quote:CO2 lags temprature by about 800 years therefore how can CO2 drive temperature....????
What on earth are you talking about? If they are in the atmosphere, carbon dioxide, water vapour and other greenhouse gases act rapidly to absorb outgoing LW IR radiation, which is then re-radiated in random directions. The net effect is an increase in temperature.
We see the same effect in Winter. Water vapour is a greenhouse gas just like carbon dioxide. If the humidity is low, the nights will be cooler. Why do you think this is? It's because the heat escapes via the radiated Long wave Infrared. If there is rain during the day and the night is more humid, the greenhouse effect of the extra water vapour in the air results in higher night time temperatures.
That's the greenhouse effect in action. There is no 800 year lag. It's the same with carbon dioxide, except that CO2 stays in the atmosphere regardless of ambient temperature.
The greenhouse effect is a result of the innate properties of certain gas molecules to absorb and re-radiate IR from the Earth's surface. Atmospheric Physics 101.

I suppose you're talking about ice cores.
What causes ice ages to start and finish again? Surprise me. What would any climate scientist in the world cite as the reason?
I'll make it easy for you:
A. Variations in Solar Activity caused by Orbital Variations.
B. A release of CO2 into the atmosphere causing warming.
C. Volcanoes
D. God willed them to occur.
Multiple choice. See if you get it right.
Did you enjoy it? Ok Here's another.
What do climate scientists say causes increases in Global temperature from time to time?
A. Always CO2
B. Always Water vapour
C. Always Solar Activity (orbital and other factors)
D. A combination of these factors and others, and the causes are not always the same.
Well?
