Global warming and mass extinctions: What we can learn from plants from the last ice age
79% Informative
New analysis methods, applied to ancient plant DNA, reveal how hard-hit plants were and are by global warming.
Using fragments of plant genetic material (DNA) deposited in lake sediments, they were able to gain new insights into how the composition of flora changed 15,000 to 11,000 years ago during the warming at the end of the last ice age .
This comparison can offer an inkling of what might await us in the future.
For the first time the experts were able to determine extinction rates for plants.
Grasses and shrubs are at a higher risk of disappearing than woody plant species.
Species in regions with high biodiversity are more often at risk than are less "special" species.
The extinction rate was at its highest at the beginning of the current warm phase.
