- #Arctic climate rankings are in for April 2025: zacklabe.com/archive-2025/. Low ice volume continues as we move into the melt season. #OpenScience #OpenData #SciComm #DataViz
- Another monthly climate change indicator update: 🫠 + Global surface air temperature: 📈 + Carbon dioxide (CO₂): 📈 + Methane (CH₄): 📈 + Nitrous oxide (N₂O) : 📈 Graphic available at zacklabe.com/climate-chan...
- Monday ice update - #Arctic sea ice extent is currently the 7th lowest on record (JAXA data) • about 40,000 km² below the 2010s mean • about 510,000 km² below the 2000s mean • about 970,000 km² below the 1990s mean • about 1,340,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i... ❄️🥼🌊🛠️
- Now here's a map view of temperature departures averaged during the last 6 months. The largest anomalies were over the Arctic and into Eurasia. 🟥 [red] warmer than average 🟦 [blue] colder than average Data from GISTEMPv4 (data.giss.nasa.gov/gistemp/)
- Up to 100°F today near the US-Canada border... in early/mid-May... not great!! Graphic from www.karstenhaustein.com/climate
- Looking back over the last 6 months, most latitude bands observed above average temperatures, except near the South Pole. [Plot shows zonal-mean surface air temperature anomalies, where latitude = x-axis (not scaled by distance). Data from NASA/GISS GISTEMPv4.]
- Some pretty unusual warmth (for this time of year) stretching across the northernmost portions of the #Arctic Ocean this weekend. Definitely not ideal as we move into the melt season... Graphics from zacklabe.com/arctic-tempe... and www.karstenhaustein.com/climate.
- Watch what happens. Changes in the age of #Arctic sea ice during springtime... Note that younger sea ice is usually thinner and more vulnerable to melting. Data from doi.org/10.5067/UTAV...
- Methane (CH₄) is a potent greenhouse gas. Here are the newest monthly observations (upper right corner)... 📈 January 2025 - 1935 ppb January 2024 - 1928 ppb Data from @noaa.gov: gml.noaa.gov/ccgg/trends_...
- Friday ice update - #Arctic sea ice extent is currently the 10th lowest on record (JAXA data) • about 70,000 km² above the 2010s mean • about 350,000 km² below the 2000s mean • about 790,000 km² below the 1990s mean • about 1,180,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i... ❄️🥼🌊
