How much do dirt roads contribute to global warming or pollution?

I cant find emmision data from a Univ of Iowa dirt roads study but I remember someone said it was more 500-1000 times more massive than CO2 from cars that travel on them. Dirt roads are a threat to our planet we need to close them.

The EPA and Air Quality boards should focus on this if it is true.

How to create a steady flow of carbon dioxide in a controlled environment?

I need to do an experiment on the effects of Carbon Dioxide on the growth of ragweed.

Is there a way to create a steady flow or a pattern of releases of carbon dioxide in a greenhouse, or any controlled environment that is not to large?
Okay, I’ve determined that combining sulfuric acid and chalk also prduce carbon dioxide, now I just need to know how I would measure the percent of CO2 in the air.

How can climate scientists using in some cases only 30 years worth of data?

Say for a fact that we know that man is the main driving factor behind climate change. Just because the temperature has risen from a global minimum and CO2 has increased during the same time frame doesn’t mean that CO2 and methane are driving the temperature change.
For MTR and others who spout the use of tree rings etc to recreate past temperature history, than why does the US EPA now is seriously doubting this information? That is one of the points that I am trying to make, the more research into the climate the more the AGW models are being filled with doubts.
