       | > We tested eight annual and seasonal climate variables,
       | including temperature, precipitation, frost days, and atmospheric
       | CO2 concentrations in a mixed-effects model framework to account
       | for city-to-city variation. We found that mean annual temperature
       | was the strongest predictor of these four pollen metrics (P <
       | 0.0001 for all metrics; Fig. 2 and SI Appendix, Table S4). The
       | full mixed-effects models explained 51-90% of the variance (i.e.,
       | conditional R^2) in pollen metrics, and mean annual temperature
       | alone (i.e., marginal R^2) explained 14-37% of the variance in
       | pollen metrics (SI Appendix, Figs. S4 and S5 and Table S4).
       | Notably, while atmospheric CO2 concentrations were sometimes
       | included in the group of the most parsimonious models, the
       | variation explained was often quite low (e.g., annual integral
       | R^2 marginal = 0.01).
       | 
       | I'm not sure what I expected, but temperature fluctuations seem
       | like a sensible primary driver of pollen count. Other variables
       | that I think might be interesting include wind speed and relative
       | humidity.
