Some two decades ago, Root and Schneider (1993) wrote that CO2-induced changes in global climate were expected – by them and other climate alarmists – to occur “too fast for evolutionary processes such as natural selection to keep pace,” while adding that this phenomenon “could substantially enhance the probability of extinction of numerous species.”
This famous but unsubstantiated declaration has ever since pervaded the thinking of the world’s climate-alarmists. But is the highly-hyped contention correct? This document broaches that question as it pertains to demonstrable CO2-induced changes in natural (i.e., non-agricultural) terrestrial vegetation, as revealed by a number of subsequent scientific studies.
