Climate & Ocean Data Update2026-10-05October 2026 Climate Baseline: Record-Warm August, 427.55 ppm CO2, and an Arctic Minimum at 4.60 Million km²The October baseline carries NOAA's record-warm August and the 427.55 ppm Mauna Loa CO2 reading, NASA's September sea-level point, the Arctic's 4.60 million km² seasonal minimum, a strengthening El Nino, and current carbon-budget context.2
Climate & Ocean Data Update2026-09-05September 2026 Climate Baseline: July Heat, 429.12 ppm CO2, and Arctic Ice at 8.29 Million km²A citable September baseline covering July global heat and CO2, the August sea-level snapshot, Arctic ice, ENSO risk, and carbon-budget context.1
Climate & Ocean Data Update2026-08-05August 2026 Climate Baseline: June Heat, 431.44 ppm CO2, and July Sea LevelA citable August snapshot of June temperature, atmospheric CO2 and Arctic sea ice, plus NASA's July sea-level point and the latest carbon-budget context.
Climate & Ocean Data Update2026-07-05June 2026 Climate BaselineJune’s climate baseline updates the latest available temperature, CO2, sea-level, Arctic sea-ice, ENSO, and extreme-event signals with dataset-level citations and pathway context.
Climate & Ocean Data Update2026-06-05May 2026 Climate BaselineMonthly digest covering four core planetary climate indicators as of June 5, 2026. Arctic sea ice in May 2026 logged its lowest Oct–May average in 48 years of satellite records. Temperature (+1.43°C above pre-industrial), CO₂ (431.12 ppm), and sea level (95.8 mm above 1993 baseline) report confirmed April 2026 values — May agency releases arrive June 5–11. An 82%-probability El Niño is now loading, and WMO puts an 86% chance on a new warmest year by 2030.
Climate & Ocean Data Update2026-05-17April 2026 Climate BaselineMonthly digest of April 2026's four core climate indicators: global temperature +1.43°C above pre-industrial (joint 3rd warmest April), CO₂ at record 431.12 ppm, Arctic sea ice second-lowest April on record, and cumulative sea-level rise reaching 95.8 mm above the 1993 baseline — with IPCC pathway context and ESG-ready dataset citations.
