A recent study has shown that the extreme rise in global temperatures over 140 million years led to mass extinctions and significant changes in plant diversity, especially during two major periods in the mid-Cretaceous and the early modern era. The researchers confirmed that these warm periods were accompanied by the destruction of plant diversity and the evolution of new groups of flowering plants, which are now the most diverse and productive on Earth. Scientists warned that warming caused by human activities could accelerate the rate of plant extinction beyond that of previous warm periods, posing an unprecedented threat to plant diversity.
