Reply #29: Poison ivy is not a bacteria [View All]

[NickB79]

Increased plant growth is an obvious reaction to a longer growing season as global warming accelerates.

I have grown bacteria in anaerobic (no O2, plenty of CO2) conditions in microbiology class. Most species DIE without oxygen; only certain species such as botulism survive without O2. You boost CO2 and bacteria generally slow their rate of reproduction. Comparing these to photosynthetic plants such as poison ivy that actually metabolize CO2 makes no sense.

"From a newly posted thread addressing a recent 30% increase in CO2."

CO2 constitues ~0.03% of the gases found in the Earth's atmosphere. If CO2 doubled to 0.06% through fossil fuel use, we would only lose 0.06% of the atmospheric O2 through bonding to the carbon atoms released from fossil fuel burning. Hardly the huge drops you believe are occurring.
