The paper analyzes global tree crown architecture to identify factors driving diversity in height, crown size, and shape across species.

The paper reassesses climate change risks for terrestrial ecosystems by transforming climate data into phytoclimates, finding significant changes and novel climates by 2070.

The paper compares past and future climate change impacts on species, finding that range shifts will need to be more extreme in the next 50 years than in the past 6000 years, with physiological traits determining vulnerability.
