Climate indicators put warming near 1.5°C threshold
Guardian’s Victor Gbonegun and EU Reporter reported that the 2026 Indicators of Global Climate Change update, published in Earth System Science Data, estimates human-driven warming reached 1.37°C in 2025 and could surpass 1.5°C in about four years. The report puts 2024 greenhouse gas emissions at a record 56.8 billion tonnes of CO2 equivalent, mainly from fossil fuels. EU Reporter also reported a remaining 1.5°C carbon budget of 130 Gt CO2 from the start of 2026, potentially exhausted in about three years at current emissions levels.
Why it matters
The update narrows the window for keeping warming near the Paris Agreement’s lower temperature limit while showing heat accumulation, sea-level rise and marine heatwaves still accelerating.

EU Reporter coverageNOAA declares El Niño in tropical Pacific
Earth.Org’s Martina Igini reported that NOAA has declared El Niño conditions in the tropical Pacific and expects the event to intensify to moderate or strong levels this fall. NOAA projects a 63% chance that equatorial Pacific sea surface temperatures exceed the 2°C threshold for a very strong event. ScienceDaily reported that NASA and European partners are tracking warm Kelvin waves with Sentinel-6 Michael Freilich, with sea levels near Peru more than 5.9 inches above long-term averages by mid-May.
Why it matters
A strengthening El Niño can reshape drought, flood and cyclone risks globally and raise the odds of another record-warm year when layered on human-caused warming.

ScienceDaily coverageAntarctic winter sea ice missing near Bellingshausen
The Times of India reported that satellite monitoring shows roughly 650,000 square kilometers of expected winter sea ice has failed to form in the Bellingshausen Sea off West Antarctica. The anomaly coincided with an Antarctic Peninsula winter heatwave: Argentina’s Esperanza station reached 15.4°C on June 5 and 13.4°C on June 6, far above the early-June average of about -6.2°C. Scientists cited in the report said this is the third exceptionally low Bellingshausen event in four years and warned that missing sea ice can expose ice shelves near Thwaites and Pine Island glaciers to waves and storms.
Why it matters
Persistent winter sea-ice deficits could amplify ocean warming, disrupt Antarctic ecosystems and weaken natural buffers protecting glaciers that contribute to sea-level rise.

Still unclear
OPEN QUESTION
Will this El Niño become very strong?
NOAA’s 63% probability of crossing the very-strong threshold leaves several months of uncertainty over peak intensity and regional drought, flood and cyclone impacts.
OPEN QUESTION
Can AI demand stay compatible with clean grids?
Microsoft’s possible retreat from 24/7 clean power in Virginia highlights a broader unresolved tension between rapid data-center expansion, grid reliability and fossil-generation lock-in.
