Sea surface temperatures are warming across the periphery of the Ocean in June during the satellite-era. This is evident in both the north Pacific and north Atlantic.

@Brad_Rosenheim This does not have a large effect. In fact, 1982 was a particularly cool SST in the Arctic, which is shown in the timeseries in the link above.

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

Polar stereographic map showing Arctic sea ice concentration trends in % per decade. Red shading is shown for declining sea ice and blue shading is shown for increasing sea ice. All areas are observed long-term sea ice declines during the month of June. Trends are calculated over the 1979 to 2023 period.

    sea ice extent is currently the 10th lowest on record (JAXA data)

    • about 60,000 km² above the 2010s mean
    • about 590,000 km² below the 2000s mean
    • about 1,160,000 km² below the 1990s mean
    • about 1,680,000 km² below the 1980s mean

    Line graph time series of 2024's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with white for the 1980s, green for the 1990s, blue for the 2000s, and purple for the 2010s. Thin white lines are also shown for each year from 2002 to 2022. 2024 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between April and July by looking at the decadal average line positions.

    And now visualizing the June solstice from the polar regions...

    Animation looks downward at the North Pole (left; ☀️) and South Pole (right; 🌙) over a 24-hour period. Graphic from https://zacklabe.com/arctic-climate-seasonality-and-variability/

    Animation shows two orthographic maps looking downward at the Northern Hemisphere (left) and downward on the Southern Hemisphere (right) using hourly solar radiation data. The Arctic and Antarctic circles are also denoted with dashed lines. Nighttime and daytime are visible given this data information.

    @hawe11 Yah, unfortunately the colors get a bit washed out toward that end of the scale in this visual.

    @ZLabe What just clicked for me is that our irradiance around noon is not too different from what the North Pole is getting all day long right now (40 S).

    The total area of #Arctic sea ice is declining in every month of the year. However, the largest losses of sea ice are observed during the late summer and early fall.

    For more information: https://repository.library.noaa.gov/view/noaa/56616. Concentration means the fraction of ice cover.

    Now back to your regularly scheduled programming - There is a widespread positive trend for increasing precipitation across the Ocean in June, which is largest near the North Pole & some coastal land regions

    Well now I can finally share - I just started my first day as a federal scientist at NOAA's Geophysical Fluid Dynamics Laboratory.

    I'll be continuing research on improving our understanding of climate prediction and projection, especially with data-driven approaches for high-impact extremes.

    Trends in June sea ice thickness across the Ocean - red shading corresponds to areas of thinning ice over the last few decades. The largest declines are in the East Siberian Sea and Chukchi Sea regions.

    Enjoy your week! Here's your Monday ice update - sea ice extent is currently the 9th lowest on record (JAXA data)...

    • about 200,000 km² below the 2010s mean
    • about 690,000 km² below the 2000s mean
    • about 1,230,000 km² below the 1990s mean
    • about 1,700,000 km² below the 1980s mean

The decadal averages are shown with different colored lines with white for the 1980s, green for the 1990s, blue for the 2000s, and purple for the 2010s. Thin white lines are also shown for each year from 2002 to 2022. 2024 is shown with a thick gold line.

    @ZLabe

    Hey Zack, this is intended to be a "back at you" message, not a criticism of your excellent technical work.

    I've been following you and your excellent data-driven graphics for a while now.

    The reason I'm commenting: There is too much doomism in today's climate messaging. It is well warranted, scientifically, and it generates clicks. But it does not inspire action. And action is what we desperately need. Across all sectors of our economy and our politics.

    Are you a doomer? I don't believe so. You seem like a brilliant, data-driven scientist. But a continuous thread of amazing graphics showing what a shitshow we're in becomes, after a while, just more doom.

    So I beseech thee: sprinkle into your messaging some actionable things people can do to help stabilize, or better, reverse the trajectory we're on.

    Much respect to the work you're already doing. Ciao, Mark

    Unsurprisingly, the last three months globally were the warmest March-May in our records...

    [(Preliminary) data/info: https://data.giss.nasa.gov/gistemp/faq/]

    Line graph time series of global mean surface temperature anomalies for every March-May from 1880 through 2024. A red 30-year lowess smoothing line is also shown. Anomalies are computed relative to a 1951-1980 baseline. The global mean surface temperature anomaly in March-May 2024 was +1.29°C. There is large interannual variability and a recent long-term warming trend.

    A summary of last month can be found from the NSIDC at https://nsidc.org/arcticseaicenews/2024/06/an-early-hudson-bay-opening/

    *SST data set (OISSTv2.1) is only available since about 1982

    showing Arctic sea ice concentration and sea surface temperature anomalies for every May from 1982 to 2024. Blue shading is shown for colder anomalies, and red shading is shown for warmer anomalies. Sea ice concentration is shown with shades of white and grey. There is large spatial variability, but long-term warming sea surface temperatures and decreasing sea ice. A gold line for the 1982-2010 sea ice extent median is also shown.
