‘Human-caused climate change is transforming the Arctic’

The Arctic is experiencing a period of unparalleled warmth “that is unlike any period on record,” according to the 2018 Arctic Report Card from the National Oceanic and Atmospheric Administration (United States Department of Commerce).

According to the report  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.

– Arctic Report Card: Update for 2018 – Tracking recent environmental changes, with 14 essays prepared by an international team of 81 scientists from 12 different countries and an independent peer-review organized by the Arctic Monitoring and Assessment Programme of the Arctic Council.

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.

“The changes we are witnessing in the Arctic are sufficiently rapid that they cannot be explained without considering our impacts on the chemistry of the atmosphere,” Thomas Mote, a research scientist at the University of Georgia who authored part of the report, told CNN in an email.

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.

    • what they tend to forget; the greater the sea-ice reduction.. the quicker the BLUE sea absorbs more light/heat & quickens the process. All this talk about ‘Its just sea-ice & will have no effect’ (on sea level rise) is just bunkum. The planet/water is all interconnected, the loss of ice in one area will effect the whole eco-system;
      sorry for using such ‘big words’ folks 😦

      Im just fedup with hearing & reading C-C B-S

    So it’s got cooler then? Thank god for that.

    The arctic is transformed every summer and winter season by massive ice melts and freezes:
