Last Notes npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Have a good week! Here's your Monday ice update - #Arctic sea ice extent is currently the 8th lowest on record (JAXA data)... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe A data-driven picture of our rapidly changing planet - updated through June 2026... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Oh look, another all-time record high temperature shattered... Salt Lake City, Utah today. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe No surprises here - #Arctic Ocean stripes are off the scale. The Arctic is warming faster than anywhere else in the world. #ShowYourStripes npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe I just want to point out that temperatures over land (where we all live) have warmed over twice as fast as ocean surface temperatures. The latest update through 2025 is... not great 🥴 npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe A last look at the timing of phenological spring across the contiguous U.S. this year. Red means spring came early for plants. Truly remarkable to see the conditions across the West. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Trends in sea ice concentration are still confined to the outer edges of the #Arctic Ocean in May. In particular, losses have been largest in the Barents Sea near Novaya Zemlya. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Looking at temperature departures over the last 6 months... note some of the hotspot regions, including of course the Arctic, but also central Asia and western North America. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Looking back at April 2026, most latitude bands observed above average temperatures, except near the South Pole. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Have a good week! Here's your Monday ice update - #Arctic sea ice extent is currently the 2nd lowest on record (JAXA data)... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Quite a bit of spatial variability in the pattern of temperature anomalies across #Antarctica in April 2026, though the warmth around the peninsula has been a pretty persistent feature lately. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe This is an important graph for understanding changes in the global climate system. The data/running means are computed through March showing internal variability (bumps) and forced long-term warming (trend ➡️ human-caused climate change). npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe 🚨 Friday ice update - #Arctic sea ice extent is currently the *lowest* on record for this time of year (JAXA data)... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Carbon dioxide averaged nearly 431 ppm in April 2026 (new record high)... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Sea surface temperatures continued to warm in the far eastern Pacific in April, as El Niño is likely to develop (find trusted sources to follow and not just the hype). npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Last month was the 11th lowest #Antarctic sea ice extent on record for the month of April. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Trends in May temperatures over land areas for the last 50 years... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Happy start to May! These maps show the regional patterns of temperature change during this month over the last four decades. Note the larger warming over land areas and relative hotspots over different high latitude areas. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Have a great weekend! Here's your Friday ice update - #Arctic sea ice extent is currently the 3rd lowest on record (JAXA data)... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Cumulative change in the mass of glaciers from all around the world - preliminary data just updated through 2025 ☹️ npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Monday ice update - #Arctic sea ice extent is currently the *lowest* on record for the date (JAXA data)... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe As I keep saying, this is easily one of the most anomalous out-of-season heatwaves that I’ve observed. It’s also remarkably large in the extent of area impacted by the record heat. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Excessive heat warnings, red flag warnings for wildfire conditions, and monthly temperature records being shattered yet again. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Honestly, this historic heat dome across the West is really hard to put into words for me. Temperatures over 110°F (43°C) in March, shattering all-time monthly records on multiple consecutive days, and not just by a little. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Even in a world of extremes, some events still stand out to me. This is one. All-time monthly records are being shattered. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Sea surface temperatures are way above average in the Labrador Sea, especially where ice coverage is thin along the climatological ice edge. These warm anomalies also extend around Greenland toward Iceland for the February 2026 monthly mean. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Very similar to last year, sea ice in the Sea of Okhotsk basin has been quite slow to grow. Total ice extent for this region is currently at record low levels. Also compare now to the 1980s! npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Looking forward to a few talks this week on why sustained climate observing networks matter, and how the impacts of regional climate trends and extreme events vary by season. As usual, I’ll try to share the slides on my personal website afterward. Trying to keep the public climate change conversation going... 🥹 npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe We have a new study out! In this work, we examine how the Gulf Stream and Kuroshio-Oyashio Extension co-vary, and this is tied to atmospheric variability and potentially sea-ice anomalies. However, this linkage may be changing in a warming world... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Hope you will join us next week! I'll be leading our next free webinar that will review 2025's global climate stats and extreme events. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe "In a reversal, the agency plans to calculate only the cost to industry when setting pollution limits, and not the monetary value of saving human lives, documents show." https://www.nytimes.com/2026/01/12/climate/trump-epa-air-pollution.html npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Here are the latest monthly-averaged observations of global methane (CH₄; a potent greenhouse gas)... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Carbon dioxide (CO₂) averaged about 427 ppm in December 2025 npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe A summary overview showing the standardized anomalies of annual #Arctic sea ice extent by region - now updated through 2025 npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe 2025 was the hottest year on record for ocean heat content. Unfortunately, we now say this every year. 🥹 npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe My monthly #Arctic temperature graphics are now updated for December 2025. Another unusually warm month. See: https://zacklabe.com/arctic-temperatures/ #DataViz #SciComm #OpenScience #OpenData npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Last year was obviously the warmest on record for the North Pacific Ocean... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe 2025 observed the lowest #Arctic sea-ice extent AND the lowest sea-ice volume for their yearly average values. This comes as no surprise to me as the polar environment continues to change. The consequences are far-reaching. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Modeled reconstruction of December #Arctic sea ice volume since the year 1901 - comparison between PIOMAS-20C and PIOMAS data sets now updated through 2025 (new record low)... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Just in - "According to Climate Central, 2025 ranks as the third-highest year (after 2023 and 2024) for billion-dollar weather and climate disasters — with 23 such events costing a total of $115 billion in damages." npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Last month's total #Arctic sea ice volume averaged the *lowest* on record for the month of December... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe A comparison between recent satellite-derived sea ice observations and a reconstruction of ice extent since 1850 for the month of December. 2025 was a record low. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe The first week of the new year is already flying by. Here's a look at how temperatures have changed around our planet over the last four decades in January... npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe Last month was statistically tied for the 5th lowest #Antarctic sea ice extent on record for the month of December. npub19k206sfhfaqehnkv4yeev8fwr6exthmjvlxyqctp0fzwf0vg92rqe08dk6 Zack Labe I’ll be working this weekend to update my daily near-real time website visualizations for the switch from 2025 to 2026. Unfortunately, this means manually updating the style for each one. Thanks for your patience...
