El Niño 2026: How Strong, and the La Niña That Follows

A very strong El Niño is coming, but physics and AI forecasts agree it isn't a clear record on NOAA's RONI index. The signal, the warming, and the 2027 La Niña.

An AI model forecast this El Niño as very strong back in April; NOAA's physics plume has since climbed to cross it. Two methods converging. On RONI, warming stripped out, it isn't clear record territory. The AI now flips it to a La Niña in 2027. 4billionyearson.org/posts/the-20...

UK Plug-In Solar Rules: What You Can Install From 27 Aug

UK plug-in solar becomes law on 27 August 2026, but it's not plug-and-play: one device per household, no cladding or timber balconies, and batteries stay banned.

AI compute per human, globally: ~1.2 TFLOPS. That's already more than a budget phone (0.5) and approaching flagship-phone level (2.0), though still short of a laptop (7.0). 4billionyearson.org/ai-dashboard #ArtificialIntelligence #DataViz

Frontier AI data centers now use ~94.9 TWh of electricity ... more than Kuwait or Colombia generate annually. And that's before counting cloud inference or smaller facilities. Dashboard: 4billionyearson.org/ai-dashboard #AI #ClimateData

2026 (Jan-Jun) = UK's hottest first half on record. Yet every month has had less sunshine than 2025, the sunniest year ever. Temp and sunshine have decoupled. I is nighttime warming? Change in weather patterns? Chart + more: 4billionyearson.org/climate/uk #UKWeather #ClimateChange

What if the whole country saw the full picture? This is a national emergency. The impacts are already here. But the solutions exist. Communities are watching the People’s Emergency Briefing and discussing what to do next with neighbours and MPs #EarthDay Screenings www.nebriefing.org/screening-map

#1 of 234 countries in warm anomaly. That's a framing I haven't seen before, have you? Icelanders also held a wake for a vanished glacier and recognized AMOC collapse as the official national security issue it deserves to be in all states. But 2024 pc CO2 emissions were 25t 🤯 Even higher than 2012 🙈

Iceland just had its warmest spring on record. In May, it ranked #1 of 234 countries at +5.15°C/+9.3°F. The NAO was negative that month. Should've cooled things down. Didn't. Why? Full breakdown: 4billionyearson.org/posts/warmes... #ClimateChange #Iceland #ArcticAmplification
