Highlights
The fossil record suggests that climate change was the major driver of plant extinctions and regional extirpations from the Pliocene until recently, when anthropogenic habitat loss became dominant.
Known recent plant extinctions are disproportionately few in comparison with well-studied animal taxa, but many more species are probably committed to inevitable extinction unless given targeted support.
Recent warm-edge extirpations demonstrate the growing impact of anthropogenic climate change and show that predictions of massive climate-driven extinctions later this century are plausible.
The proximate causes for population extirpations are still rarely known but are likely to be highly varied and both species and location specific."
