🚨Earth has a mysterious triple symmetry that may influence its climate
New research finds that a circle running along the 27° east & 153° west meridians divides the globe into 2 halves with equal reflectivity & this may have implications for #SolarGeoengineering schemes.🧵1/10
2/ This study matters bcz Earth's reflectivity (albedo) controls how much solar energy stays in the climate system.
For decades, researchers knew the NH & SHemispheres reflect similar amounts of sunlight. But nobody had seriously looked for similar patterns across longitude.
3/ Using 25 years of satellite observations, researchers discovered that the 27°E meridian uniquely splits Earth into eastern & western hemispheres with almost identical reflected sunlight. Not 20°E. Not 40°E. Just one remarkably precise divide.
From Stardust’s SAI particle reveal to US Congress oversight calls, @ARIA_research funding, @UNEP report, EPRS governance briefing & UK public support for SRM research, key SRM headlines from May:🧵0/12
Company discloses 0.5µm amorphous silica–based particles & calcium carbonate core–shell variants, deployed at ~18km altitude, targeting up to ~1% solar reflection with monitoring & dispersal systems.
1/
2️⃣ US Congress requests @NOAA geoengineering briefing:
🚨A new @EarthsFutureEiC study tests an Arctic intervention: flooding winter sea ice with seawater to see if it can become thicker, brighter, and more resistant to summer melt.
The answer comes from a real field experiment in the Canadian Arctic.🧵1/11
2/ The experiment was conducted in Cambridge Bay, Nunavut (Canadian Arctic) using a ~1 km² sea-ice field site.
Researchers divided the ice into control plots (no flooding) and treated plots (artificial flooding) to directly compare outcomes under identical conditions.
3/Process:
•Seawater was pumped from ocean
•Spread manually/with equipment over ice surface during winter
•H2O rapidly froze due to sub-zero air temp
•Process repeated in some plots multiple times over winter
Each flooding cycle added new frozen layer on top of existing ice
🚨Monthly Solar Geoengineering Updates (April'2026)🚨
From EU calls for an #SRM deployment moratorium & WHO-linked health-centered governance report, to Stardust publishing its own SRM rules, key SRM headlines you need to know from past month:
🔗
The private SRM company publishes voluntary rules and safety guidelines, but experts raise concerns over transparency, unknown aerosols, and private control of planetary-scale interventions.
1/12
2️⃣ WHO-linked report calls for health-centered SRM governance:
A pre-print urges SRM governance centred on human health, equity, and Global South inclusion, stressing SRM must never replace emissions cuts (“non-substitution” principle).
