Differences in the spatial patterns of July temperature anomalies in the #Arctic versus #Antarctic by decadal means... [Data from @copernicusecmwf.bsky.social ERA5 reanalysis]

Looking back at temperatures over the last 3 months - find your location... 🟥 [red] warmer than average 🟦 [blue] colder than average Data information at data.giss.nasa.gov/gistemp/faq/

June 2024 data is now available for both Antarctic sea-ice thickness/volume (zacklabe.com/antarctic-se...) and global sea-ice volume (zacklabe.com/global-sea-i...) from GIOMAS. Unusually low, but no new monthly records.

Both poles are now observing unusually low sea ice conditions, and therefore global sea ice extent is yet again near record low levels for the current date... More sea ice graphics available at zacklabe.com/global-sea-i...

Global mean sea surface temperature anomalies (departure from average) so far this year ➡️ warmest on record [Data from NOAA ERSSTv5 averaged over January to June]

It's another historic year in the #Antarctic. With ice growth remaining slow (austral winter), the magnitude of the Antarctic sea ice departure is almost as anomalous as last year's record. Wow. Full seasonal cycle graphs available at zacklabe.com/antarctic-se....

Happy to share the final version of our new review paper, which is out in BAMS (#OpenAccess): doi.org/10.1175/BAMS... This community-driven paper explores the utility of #Arctic sea ice prediction through a collection of statistical and dynamical models.

Carbon dioxide (CO₂) averaged about 427 ppm in June 2024 10 years ago June averaged about 401 ppm Preliminary data: gml.noaa.gov/ccgg/trends/

Methane (CH₄) is a potent greenhouse gas. Here are the newest monthly observations... March 2024 - 1930.75 ppb March 2023 - 1919.70 ppb + Data: gml.noaa.gov/ccgg/trends_... + More info on recent trends: pnas.org/doi/abs/10.1...

Thank you! I am glad they are useful! :)

Monday ice update - #Arctic sea ice extent is currently the 8th lowest on record (JAXA data) • about 30,000 km² below the 2010s mean • about 970,000 km² below the 2000s mean • about 1,720,000 km² below the 1990s mean • about 2,510,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i...

Over the last three months, the temperatures assessed across all latitude bands were warmer than the 1951-1980 average, except around the Southern Ocean/Antarctic. [Plot shows zonal-mean surface temperature anomalies, with latitude = y-axis (not scaled by distance). GISTEMPv4.]

YET AGAIN, last month was the hottest June on record globally... [(Preliminary) data/info: data.giss.nasa.gov/gistemp/faq/]

#Arctic climate rankings are in for June 2024: zacklabe.com/archive-2024/. Another mostly uneventful month for these mean statistics.

Comparison of monthly temperature anomalies in the Arctic versus the Antarctic so far in 2024 (yellow lines). The other lines show the monthly anomalies for years from 1940 (blue) to 2023 (red). Data from cds.climate.copernicus.eu/cdsapp#!/dat...

A closer look at temperature anomalies last month in the Arctic. Anomalies well exceeded 5°C above the 1981-2010 average across parts of the Siberia coast. Data from cds.climate.copernicus.eu/cdsapp#!/dat...

We are having a timely workshop on all aspects of extreme heat this week at Columbia University (climate.columbia.edu/extreme-heat...) with a wide range of participants from across disciplines. I presented some of our recent work using GFDL's SPEAR model. Poster link: zacklabe.com/wp-content/u...

Temperature anomalies over the last month (left), 3 months (center), and 12 months (right) across the Northern Hemisphere. The largest anomaly (by magnitude) was along the Arctic Ocean coast in Siberia. Data from @copernicusecmwf.bsky.social ERA5 reanalysis cds.climate.copernicus.eu/cdsapp#!/dat...

Looking at the different seasonality and trends in the magnitude of monthly temperature anomalies since 1940 for the Northern Hemisphere and Southern Hemisphere. 2024 is a historically warm year. Data from cds.climate.copernicus.eu/cdsapp#!/dat...

Record warm sea surface temperatures continued last month in the northern half of the Atlantic Ocean... Data available from NOAA ERSSTv5: psl.noaa.gov/data/gridded...

Monday ice update - #Arctic sea ice extent is currently the 12th lowest on record (JAXA data) • about 170,000 km² above the 2010s mean • about 660,000 km² below the 2000s mean • about 1,400,000 km² below the 1990s mean • about 2,140,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i...

🚨 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

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...
