Despite the now waning El Niño, the global mean sea surface temperature set a new record for the month of March this year...

Have a great rest of your week! Here's your Monday's ice update - sea ice extent is currently the 14th lowest on record (JAXA data)...

• about 110,000 km² above the 2010s mean
• about 290,000 km² below the 2000s mean
• about 820,000 km² below the 1990s mean
• about 1,300,000 km² below the 1980s mean

ZLabe,

@grootinside This is expected, as the other solid colored lines are decadal averages, which smooth out the day-to-day variability. If you look very closely, there are thin gray lines, which display each year from 2002 to 2023 and are also very zigzagy.

My monthly temperature graphics have been updated for March 2024, which was fairly average across much of the region: https://zacklabe.com/arctic-temperatures/

🚨 Methane (CH₄; potent greenhouse gas) also reached another preliminary record high value for its latest monthly update (December 2023 - 1932.2 ppb)

December 2022's global methane abundance was 1924.6 ppb. Data freely available from https://gml.noaa.gov/ccgg/trends_ch4/

🚨 I have another record to share - carbon dioxide (CO₂) averaged a record high of 425.4 ppm in March 2024

10 years ago March averaged about 399.9 ppm

• about 240,000 km² below the 2000s mean
• about 780,000 km² below the 1990s mean
• about 1,240,000 km² below the 1980s mean

While most of the region surrounding the sea ice edge is experiencing above average sea surface temperatures as of March 2024, the record ocean warmth globally has not been clearly observed in the Arctic region.

The largest negative anomalies of Antarctic sea ice concentration in March 2024 were observed near the Ross Sea sector.

Last month averaged the 5th lowest sea ice extent on record for the month of March.

This was 850,000 km² below the 1981-2010 average. Data from NSIDC at https://nsidc.org/data/seaice_index

March 2024 #Arctic sea ice extent was the 15th lowest on record...

This was 560,000 km² below the 1981-2010 average. March ice extent is decreasing at about 2.42% per decade. Data: https://nsidc.org/data/seaice_index

March 2024 observed unusually high levels of #Arctic sea ice in the Sea of Okhotsk. Elsewhere, most areas were near or below average (especially the Gulf of St. Lawrence).

Spring (phenological) arrived anomalously early across much of the contiguous United States. It was even record early for some areas along the northern gradient of the onset maps.

Map of the contiguous United States showing the spring leaf index anomaly as of March 30, 2024 from the USA National Phenology Network. Many areas are late this year for spring onset at over 20 days late.
