The CO2 levels in our atmosphere have been increasing steadily for the last 18,000 years, and for the record CO2 levels have historically changed without human input or intervention.

Worldwide man-made CO2 emissions account for about 0.3% of all CO2 in the atmosphere, and the idea that man-made polution is responsible for global warming is not supported by historical fact. The period known as the Hololene Maximum is a good example, it was the hottest period in human history approximately 7,500 - 4,000 years ago way before fossil fuels were used. If you look back as recently as 1940 to 1978 CO2 levels continued to rise, but temperatures dropped.

I found a interesting fact which said that growers are injecting CO2 into their greenhouses because it promotes plant growth and helps plant resist drought and disease. Sounds like maybe we need more CO2?

Getting back to the topic of the thread, I think we will still need to use oil, gas and coal for several years to come, but we do need to develop solar, wind and nuclear power with the demand for energy growing each year it will more than likley take all of the above to meet our energy demands.

I'm not sure what studies you are looking at that suggest that the amount of CO2 hasn't increased substantially over time but actual studies show that the amount of CO2 in the atmosphere has increased since the industrial revolution. Also people put CO2 in greenhouses because it blocks the short wave radiation from leaving the greenhouse which naturally warms it and increases growth ie GREENHOUSE EFFECT. Just because you think that your too old to believe something doesn't mean it isn't real.
Also try using scholarly peered reviewed journals for your sources. Anybody can put something on the internet if it is peer-reviewed then it is acurate.
