Predict the effects of climate change by studying the effects of climate change

Booth (2024) recently criticized our review on climate change and global species extinctions because we mentioned studies of introduced species but not forestry trials (deliberately introduced trees). However, as noted by Booth (2024), a relevant database is lacking for these trials, thus preventing their inclusion. More broadly, we suggest that researchers interested in extinction and other impacts of climate change should focus directly on studying the recent effects of climate change, rather than on introduced species, forestry trials, or other more indirect lines of evidence.
