year x climate interactions

[teixeirak]

I'm not intending to add these, but using this issue to note that it would be an interesting thing to do in the future, and to record some now-deleted text:

"We note that a modification of our analysis method (modeling year× climate interactions instead of DBH× climate interactions) could potentially be used to account for directional changes in climate sensitivity, which have commonly been documented (e.g., Helcoski et al., 2019; Holz et al., 2018; Maxwell et al., 2016; Peltier & Ogle, 2020; Schurman et al., 2019; Zuidema et al., 2020). In fact, a recent literature survey revealed that such non-stationarity in the climate sensitivity of tree growth occurs globally and in the majority of tested cases (Wilmking et al., 2020)."

I added a note explaining why we don't address this.
