Sea surface temperatures are substantially warming around the entire #Arctic Ocean in July during the satellite-era. This is especially large in the Kara Sea. Note the blue shading mostly corresponds to areas of sea ice.

Last month observed substantial departures in #Antarctic sea ice, which were particularly focused around the Indian Ocean sector and near the Ross/Amundsen Seas. This is a different spatial pattern compared to last year.

Latest 'cloud-free' mosaic from MODIS satellite imagery showing that most of the snow cover across land areas of the #Arctic has melted for the season. There are also signs that sea ice is beginning to retreat along coastal regions too.

The largest warming has been observed in the Siberian Arctic. Temperature anomalies/trends are smaller over sea ice in summer due to melting-thermodynamic processes.

That is a feature that is more visible in long-term trend plots (e.g., over 30 years), but not always in the monthly/interannual variability of surface temperature anomalies due to the regional influence of weather.

Trends in June sea ice concentration are still mostly confined to coastal areas of the #Arctic Ocean. The largest declines are found in the Barents Sea this time of year.

Sea ice concentration = fraction of ice-cover (observed by satellite). Info: doi.org/10.1175/BAMS...
