🚨 Once again, last month's global temperature set a new record high. This time for the month of June. Of course, this is contributing to the unusually warm summer temperatures in the Northern Hemisphere too. Summary of June data: @copernicusecmwf.bsky.social: climate.copernicus.eu/surface-air-...

My monthly #Arctic temperature graphics have been updated for June 2024. No new records. See: zacklabe.com/arctic-tempe... #DataViz #SciComm #OpenScience #OpenData

Arctic Temperatureszacklabe.com My visualizations: Arctic Climate Seasonality and Variability Arctic Sea Ice Extent and Concentration Arctic Sea Ice Volume and Thickness Arctic Temperatures Antarctic Sea Ice Extent and Concentration...

Last month continued to see below average sea surface temperatures in the Sea of Okhotsk and Bering Sea. Areas where the sea ice melted unusually early in the Hudson Bay therefore reflected the warm patch in the anomaly map. Data from psl.noaa.gov/data/gridded...

The quiet melt season continues in the #Arctic with large regional variability in the spatial pattern of sea-ice concentration. This is partially due to some (relative) thicker ice toward Siberia. Data: nsidc.org/data/g02202/.... Concentration = fraction of sea ice in a location.

Yet another tick upward for the 12-month running mean global temperature (updated through June 2024)... Graphic from zacklabe.com/climate-chan...

Friday ice update - #Arctic sea ice extent is currently the 13th lowest on record (JAXA data) • about 180,000 km² above the 2010s mean • about 620,000 km² below the 2000s mean • about 1,370,000 km² below the 1990s mean • about 2,050,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i...

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. Data by OISSTv2.1. For more info: repository.library.noaa.gov/view/noaa/56...

Last month averaged the 2nd lowest #Antarctic sea ice extent on record for the month of June This was 1,590,000 km² below the 1981-2010 June average. Data from NSIDC at nsidc.org/data/seaice_...

June 2024 #Arctic sea ice extent was the 12th lowest on record... This was 860,000 km² below the 1981-2010 average. June ice extent is decreasing at about 3.67% per decade. Data: nsidc.org/data/seaice_...

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. Data available from nsidc.org/data/g02202/...

Monday ice update - #Arctic sea ice extent is currently the 12th lowest on record (JAXA data) • about 160,000 km² above the 2010s mean • about 590,000 km² below the 2000s mean • about 1,280,000 km² below the 1990s mean • about 1,940,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i...

While not quite as anomalous as 2023, #Antarctic sea ice extent once again remains way below average for this time of year... More graphs: zacklabe.com/antarctic-se...

The mean global sea surface temperature averaged over the last three months was the highest on record relative to any other March to May period... Data from NOAA ERSSTv5: psl.noaa.gov/data/gridded...

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. Imagery from: ice-glaces.ec.gc.ca/cgi-bin/getp...

The first September 2024 outlook from the Sea Ice Prediction Network suggests yet again that #Arctic sea ice is unlikely to break a record low this summer. Read the full report at arcus.org/sipn/sea-ice...

Friday ice update - #Arctic sea ice extent is currently the 12th lowest on record (JAXA data) • about 100,000 km² above the 2010s mean • about 610,000 km² below the 2000s mean • about 1,240,000 km² below the 1990s mean • about 1,880,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i...

Aside from around the Southern Ocean/Antarctic, most all latitude bands observed temperatures above the 1951-1980 reference period for March through May 2024. [Plot shows zonal-mean surface temperature anomalies, with latitude = y-axis (not scaled by distance). GISTEMPv4 data.]

Trend in June temperatures across the #Arctic... 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. Data: @copernicusecmwf.bsky.social ERA5. More info: doi.org/10.1175/BAMS...

May 2024 data is now available from GIOMAS for both Antarctic sea-ice thickness/volume (zacklabe.com/antarctic-se...) and global sea-ice volume (zacklabe.com/global-sea-i...).

Monday ice update - #Arctic sea ice extent is currently the 10th lowest on record (JAXA data) • about 80,000 km² above the 2010s mean • about 590,000 km² below the 2000s mean • about 1,180,000 km² below the 1990s mean • about 1,750,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i...

A longer perspective for May #Arctic sea ice extent (since 1850)... You can read more about this reconstruction at carbonbrief.org/guest-post-p...

Sea surface temperatures are warming across the periphery of the #Arctic Ocean in June during the satellite-era. This is evident in both the north Pacific and north Atlantic. Data from OISSTv2.1. For more info: repository.library.noaa.gov/view/noaa/56...

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...
