SNIP: Over the past 10 years, the number of plant species on European mountain tops has increased by five-times more than during the period 1957-66. Data on 302 European peaks covering 145 years shows that the acceleration in the number of mountain-top species is unequivocally linked to global warming.
During the decade from 1957-66, the number of species on each of the 302 mountain tops increased by 1.1 species on average. Since then, the trend has accelerated: From 2007-16, on average 5.5 new species moved up to the 302 summits.
The researchers have only been able to count the plant species that have already responded to the temperature rise and actually have moved upwards. They have not studied the number of species that might be on the way upwards.
