Friday, December 21, 2018, 4:25 PM – Since 2006, the Arctic Report Card has been issued each year in comparison with historical records of reliable and brief environmental information on the current state of the various components of the Arctic environmental system.

Scientists, educators, students, decision makers, and community leaders are interested in the Arctic environment and science every year.

2018 has been a year of steady warming in the Arctic atmosphere and the ocean, and has led to extensive changes in the ecological system in both expected and unexpected ways. There is a significant level of uncertainty about what will happen to the environment in the coming years as new threats continue to grow and the region will continue to grow.

For a large part of the scientific community researching the arctic environment, it is unclear how large the event will be. Many feel that the region will not really appreciate the future climate scenario forecasts.

YEAR OF ARCHICAL SOURCES

  • In the Arctic, the air temperature continued to warm up twice faster than the rest of the earth in 2018. From 2014 to 18, they have overturned all previous records since 1900.
  • The high air temperature in the ground continued to broad, with long-term trends falling in the groundwater preservation. The melting of Greenland ice oak and lake ice is associated with an increase in flow in the summer and a tendency to warm up observed with the expansion and greenery of tundra plants.

The magnitude of the overall trend in the MaxNDVI for the 1982-2017 period (Maximum Normalized Diversity Vegetarian Index).

  • In the last two decades, the wild reindeer and caribou desert populations have dropped by about 50%, despite the increase in vegetation along Arctic tundra.
  • The old Arctic ice is diminishing, and in 2018, the Arctic sea ice is smaller, smoother, and less covered than the past. The last 12 years after the satellite was observed, the lowest 12 ice extensions occurred.

  • Regional changes in sea ice, regional temperatures and the promotion of waters from the Pacific and the Atlantic oceans depend on the late summer spatial patterns on the surface of the sea.

  • Since the 1970s, sea ice observations have shown a long-term decline in the impact of hunting, travel and coastal protection for local communities.

  • In 2018, the initial production levels of the ocean in the Bering Sea were at 500 percent normal levels as a result of the record levels of sea ice.
  • Harmful toxic moss blocks are widening across the Arctic oceans, which are contrary to the temperature of the hot sea surface. This has created a threat to the food supply in the region.

  • As in many other oceanic areas around the world, microblasting contamination in the Arctic also increases, marine life threatens, and sea forces that can eat debris.
