"The strong coupling of CO2 to antarctic temperature confirms earlier observations for the last glacial termination and the past four cycles and supports the hypothesis that the southern ocean played an important role in causing CO2 variations"
"This value is consistent with estimates based on data from the past four glacial cycles. Fischer et al. concluded that CO2 concentrations lagged Antarctic warmings by 600 +/- 400 years during the past three transitions."
"An apparent exception of the lag of CO2 to deuterium observed over most of the record occurs around 534 to 548 kyr B.P., where CO2 seems to lead dD by about 2000 +/- 500 year. We cannot conclude with certainty whether the observed lead of CO2 at this time is real or an artifact in the EDC2 time scale."
High-resolution analyses of lake sediment from southwestern Alaska reveal cyclic variations in climate and ecosystems during the Holocene. These variations occurred with periodicities similar to those of solar activity and appear to be coherent with time series of the cosmogenic nuclides 14C and 10Be as well as North Atlantic drift ice. Our results imply that small variations in solar irradiance induced pronounced cyclic changes in northern high-latitude environments. They also provide evidence that centennial-scale shifts in the Holocene climate were similar between the subpolar regions of the North Atlantic and North Pacific, possibly because of Sun-ocean-climate linkages.
We examine the climate response to solar irradiance changes between the late 17th-century Maunder Minimum and the late 18th century. Global average temperature changes are small (about 0.3° to 0.4°C) in both a climate model and empirical reconstructions. However, regional temperature changes are quite large. In the model, these occur primarily through a forced shift toward the low index state of the Arctic Oscillation/North Atlantic Oscillation as solar irradiance decreases. This leads to colder temperatures over the Northern Hemisphere continents, especially in winter (1° to 2°C), in agreement with historical records and proxy data for surface temperatures.

Even if the reason the for climate change action is based on making some dollars,if the outcome is using our resources more efficiently ,is that a bad thing?

After having done some sparse reading. I have come to the conclusion that global warming is a natural phenomenon and that man-made global warming is minuscule in comparison. I will present evidence and scientific reports to you that demonstrate a few things:
Note that clouds/water vapor make the majority of Greenhouse gas, not CO2. But Co2 is a far more imporant greenhouse gas because unlike water it cannot condense
2. CO2 rises in response to rise in Temperature, not vice versa
Water vapor accounts for the largest percentage of the greenhouse effect, between 36% and 66% for clear sky conditions and between 66% and 85% when including clouds.

So in an effort to throw out as many theories as possible, you are claiming it is both natural, and sun spot activity? I think you need to pick one, or two..
