🚨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:

Top 10 SRM Updates from April 2026

1️⃣ Stardust releases SRM “guiding principles”:

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 Image
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).

🚨Is direct air capture (#DAC) really worth the investment?

A new Nature Climate Change study shows that investing in wind & solar delivers 2-3× greater combined climate + health benefits than direct air capture across most U.S. regions, under the same budget.

Details🧵1/11 Image
2/ DAC is often promoted as essential for net-zero, removing CO₂ directly from the atm. But most studies assess it in isolation, asking: “Does it work?”

This study asks a policy-relevant question:
“What are we giving up by funding DAC instead of alternatives?”
3/ Researchers modelled cost-equivalent investments across 22 U.S. regions (2020–2050), comparing:

Direct Air Capture vs Utility-scale wind & solar

Critically, they evaluated CO₂ reductions + air pollution + health impacts. Image

🚨What happens to tropical rainforests as CO₂ rises?

New research shows higher CO₂ boosts tree growth & C uptake by pushing roots to aggressively mine scarce phosphorus.

This strengthens the C sink now, but depletes nutrients, ultimately limiting long-term C storage.🧵1/11 Image
2/ Scientists tested this in the Amazon by exposing forest patches to higher CO₂ (future-like conditions) and tracking how trees, roots, and soils responded over time. Image
3/ Step 1: More CO₂ → faster photosynthesis

Trees produce more sugars, grow faster, and pull more CO₂ out of the air.

This is the short-term “carbon sink boost.”

🚨Green roofs + enhanced rock weathering (#ERW) could turn cities into carbon sinks.

A new assessment finds Europe’s rooftops could remove tens of millions of tonnes of CO₂ by 2060, with global potential reaching hundreds of MtCO₂/yr under ideal conditions.

Details🧵1/12 Image
2/ The work is a conceptual, literature-based assessment combined with geochemical scaling.

It estimates CO₂ removal using theoretical maximum reactivity (100% mineral conversion) and extrapolates across urban roof availability in Europe and globally.
3/ Roof availability is a key input:

The study uses estimates that roofs cover ~30–32% of urban land area, and up to ~50% of impervious surfaces in dense cities, highlighting a large, currently underused surface for carbon removal deployment. Image

🚨A new study details that the climate value of algae & cyanobacteria lies not in CO₂ uptake alone, but in their capacity to generate long-lived, chemically recalcitrant C compounds, such as algaenan & carbonates that may contribute to durable sequestration pathways.

🧵1/11 Image
2/ The study adopts a conceptual synthesis framework, integrating biochemical & geochemical evidence to examine carbon fate post-photosynthetic fixation, moving beyond uptake rates to study the thermodynamic and structural persistence of biogenic carbon. Image
3/ It constructs a functional distinction between:

1) Labile carbon fractions, which are rapidly cycled through microbial respiration

2) Recalcitrant fractions, which resist degradation & contribute to long-term carbon storage across terrestrial & marine systems.
