Friday, December 21, 2018, 4:25 PM – Since 2006, the Arctic Report Card has been published annually to provide reliable and concise environmental information on the current state of the Arctic environmental system components of its relative to historical records.

Scientists, teachers, students, decision makers and the public interested in the Arctic environment and science follow the report close each year.

2018 has been another year of continuous warming in the Arctic and marine environment leading to broad changes in the environmental system in the predicted and unexpected roads. There is a lot of uncertainty about what will happen exactly in the environment in the coming years as new threats arise and continue to grow in the region.

To the vast part of the scientific community that explores the Arctic environment, knowing exactly what the size of the event is a big concern. Many feel that the future climate scenario predictions for the region could be underestimated and what is actually on the way.


  • Surface air temperature on the Arctic this 2018 continued to heat twice as fast as the rest of the ground. Between 2014-18 they have exceeded all previous records since 1900.
  • On land, higher air temperatures continued to drive rough, long-term trends in the reduction of terrestrial snow cover. Melting Icelandic Leaflet and Lake Leaflet, along with summer river growth and expansion and greening of the tundra vegetation are all associated with the observed warmth trend.

The overall trend size in MaxNDVI (Upper Normal Difference Vegetable Index) for the period 1982-2017.

  • Despite the increase in the growth of grazing vegetation across tundra and Arctic, the wildflower and wildlife herd populations have dropped from almost 50% over the last two decades.
  • Older Arctic ice has been declining and the 2018 ice of this Arctic sea continues, thinner and covers less than in the past. Since satellite observation the 12 lowest ice extension began to occur during the last 12 years.

  • Regional variation in ice and sea birds, regional air temperatures and the regeneration of Pacific Ocean waters and the Atlantic oceans is associated with late summer spatial patterns in surface surface temperatures.

Ice inconsistencies are in March (the month of the highest ice) and September (the minimum ice month). The inconsistency value for each year is the difference (in%) in the ice parts compared to the mean values ​​for the period 1981-2010

  • Sea-shore comments on coastal land since the start of the measurements in the 1970s suggest a long-term decline with impacts on hunting, travel and coastal protection for local communities.

  • The primary production levels of the ocean in the Bering Sea region during 2018, at times, were 500% higher than normal levels due to the low sea ice extension.
  • Damaging toxic algae flowers have been expanding across the oceans of the Arctic in line with warmer sea surface temperatures. This has been a threat to food sources across the region.

  • Like in many other ocean areas around the world, micro-plastic contamination has also been increasing in the Arctic, which is a threat to marine life and seabirds that can absorb the debris .
