Arctic changed due to global warming

The Arctic as we once knew it, an inhospitable, barely accessible and icebound place, is gone. Climate change has transformed it into a region that can heat up to 100 degrees, is beset by ferocious wildfires, and is covered in permafrost that is no longer permanent. The sea ice cover that has long defined the Far North is fast disappearing. This is the picture froma new international scientific assessment released Tuesday. The 2020 Arctic Report Card, a report led by the National Oceanic and Atmospheric Administration ( NOAA) points to a slew of trends that with each passing year have grown more extreme.
