Amongst the icy peaks and stony seas,
We count the plants that call such heights a home;
Traversing every sudden gale and breeze,
To better understand how they have grown.
Across the years of data in this zone,
Diversity increased at quickened pace;
Accelerating at a speed unknown.
So even in the most secluded place,
We see the consequences of our global race.
Unlike many other geological features, mountain peaks don’t move. Therefore, they represent a very useful resource for tracking long-term biodiversity in a particular area, as researchers are able to accurately survey the same exact location as their predecessors. By analysing data from 302 European mountain peaks over the past 150 years, researchers have been able to show that there has been a considerable increase in the number of plant species on these peaks, and that this increase is accelerating.
During the 10-year period from 1957-66, the number of species on each of the 302 mountain tops increased on average by 1.1 species. However, from 2007-16, the number of species on each of the 302 mountain tops increased by 5.5. By analysing the data, the researchers have also proven that this acceleration is linked to rises in temperatures caused by global warming, as changes in precipitation and nitrogen could not explain the observed increase. The accelerating increases in species richness that has been observed in these mountain summits demonstrates that global warming is having a significant impact in even the most remote places on Earth.
