Impact of Changing Climate on Arctic Ecosystems: A 25-Year Study in Northeast Greenland Shows Unpredictable Weather Effecting Flora and Fauna

Swinging into Spring in the Arctic

The changing climate has affected the natural world in a variety of ways, with anemones, gnats, and crickets being among the species experiencing ups and downs like on a roller coaster. Spring may be earlier and milder on average, but there are still storms and snow to contend with. This variability in weather presents a challenge for both plants and animals.

In the North and Arctic regions, organisms face particularly tough selection situations due to rapid warming of land areas. Researchers have been monitoring the spring activity of plants, arthropods, and birds in Northeast Greenland for the past 25 years. The data from 1996 to 2020 shows that while there has been an overall warming trend, the variability in spring warmth and snowfall has been significant.

The advancement of flowering, insect awakening, and egg-laying varies greatly among the species studied, including Lapland’s anemones, tundra willows, ticks, gorse hawks, barn owls, and wagtails. The findings of this study may come as a surprise as the trends in the first ten years of monitoring were different from those in the following years. The researchers anticipated that as time passed
