The increases in temperature that resulted in increases in CO2 levels clearly indicate that CO2 increase will have little if any effect on global temperatures. Therefore, what's the big panic about CO2 increases?Something often missed in all the rhetoric is the disconnect that exists between historical climate change and the current changing dynamics. It's not at all arguable that in the past, temperature increases preceded increasing greenhouse gas concentrations. That 700 year delay is solid in the past. That is a strong indicator of the positive feedbacks that exist. However, that historical trend doesn't fit the current anomaly. The temperature changes of the past 1000 years have not yielded what one would expect to see evidenced in the greenhouse gas concentrations. The concentration continues to rise steadily, despite the oscillations of the past.
It is plainly obvious that our increasing emissions of greenhouse gases are not caused by temperature. The spikes that precede a rise in greenhouse gases in the past show how quickly the climate can destabilize once the gases begin their rise. In our case we are adding fuel before the fire starts.
