%X Pollen counts are affected by temperature, precipitation and atmospheric CO2 levels.
Global climate change models suggest that atmospheric CO2 levels will double by the

to increased CO2. We examined whether changes in atmospheric CO2 were associated with
changes in weed pollen counts in central Indiana over the past ten years.
