Reference climate data and projected atmospheric [CO₂] (A), growing season temperature (B), and precipitation (C).

<p>(A) Projected increase in atmospheric [CO₂] (c_a) for the RCP 4.5 emissions scenario, (B) projected growing season (MAY–SEP) mean daily air temperature, and (C) projected total growing season precipitation for the next 100 years based on two downscaled climate change projections (see text). Lines represent the 10-year moving average for each series in panels B and C.
