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 like how you use examples that have nothing to do with man made global warming to try and disprove it, lol. We know that high levels of CO2 cause temperatures to rise, it happened in the period you mentioned, and has happened before. You used an example that spread almost 4000 years, this rise in CO2 is happening in a few decades.

I like how you conveniently stopped your point at 1978, one year before a major warming period happened, between 1979 and now global temperatures have risen 1.3 degrees Fahrenheit.

Also since the industrial revolution CO2 levels have risen 40%, and in that period humans have been responsible for 99% of all greenhouse gas emissions, which accumulate to 3 percent of the total CO2 in the air, not the BS number you mentioned.

Just because CO2 levels where rising in the period you mentioned doesnt mean a dramatic change will happen, it takes time to build up the levels of CO2 in the air, plus we are now cutting down way more forest than we did in that period, taking out our natural way to absorb CO2.

If you would get off of your conservative sites and look and some real scientific sources you may learn something.

And launchpad did a good job describing how people are using the greenhouse effects to grow plants, so I want bother touching on that.
