Geographic range of plants drives long-term climate change

K. Gurung, K. J. Field, et al.

This groundbreaking research by Khushboo Gurung, Katie J. Field, Sarah A. Batterman, Simon W. Poulton, and Benjamin J. W. Mills explores how plant geographic range significantly influences long-term climate change. Discover how limited ranges on the arid Pangaea supercontinent led to higher atmospheric CO2 levels, and how increased continental dispersion enhanced carbon fixation. A fascinating look at the often overlooked role of vegetation in climate dynamics!

Abstract

This research investigates the impact of plant geographic range on long-term climate change using coupled vegetation and climate models. The study finds that limited plant geographic range over the arid Pangaea supercontinent resulted in lower carbon fixation rates and higher atmospheric CO2 concentrations. Mesozoic continental dispersion increased plant range, amplifying CO2 removal, aligning with geological data. The findings highlight the significant, yet understudied, role of plant geographic range in controlling long-term climate.
