(CNN) The Arctic is experiencing a multi-year stretch of unparalleled warmth "that is unlike any period on record," according to the 2018 Arctic Report Card, a peer-reviewed report released Tuesday morning from the National Oceanic and Atmospheric Administration, an agency within the United States Department of Commerce.

The report states that human-caused climate change is transforming the Arctic, both physically through the reduction of sea ice, and biologically through reductions in wildlife populations and introduction of marine toxins and algae.

The report is yet another study from part of the US government indicating that climate change is real and having a profound impact, despite denials from the President and senior members of his Administration.

The year 2018 was the Arctic's second-warmest year on record behind 2016. The top five warmest years have all occurred since 2014.

Temperatures in the Arctic are warming more than twice as fast as the overall planet's average temperature, with temperatures this year in the highest latitudes (above 60 degrees north) coming in 1.7 degrees Celsius (3.1 degrees Fahrenheit) above the 1981-2010 average. These were the second warmest (behind 2016) air temperatures ever recorded during the Arctic year, which runs from October through September to avoid splitting the winter season.

The five years since 2014 have been warmer than any other years in the historical record, which goes back to 1900. Although Arctic temperatures have been subject to wild swings back and forth through the decades due to natural variability, they have been consistently warmer than average since 2000 and at or near record since 2014, the report states.
