| The study identifies three alteration episodes in the Jezero Margin unit: carbonate-rich ridge formation from CO2-rich fluids, later carbonate remobilization with silica precipitation, and late fluorite-bearing calcium-sulfate veins from fluids through younger fractures. | HISTORICAL | Supported |
| Lower Jezero Margin-unit exposures show a complex history of water-rock interaction, unlike the high-elevation exposures described in the study. | OBSERVATIONAL | Supported |
| At elevations above approximately −2350 m, the Jezero Margin unit has texture and chemistry indicative of slowly cooled crystalline olivine-rich rock without significant water exposure. | OBSERVATIONAL | Supported |

| The rapid syn-eruptive submarine caldera collapse at Hunga enhanced tsunami hazards, with tsunami wave heights reaching about 40 m at distances up to 100 km and associated volcaniclastic density currents damaging seafloor infrastructure. | CAUSAL | Supported |
| Repeat seafloor mapping found that the 2022 Hunga eruption deepened the caldera from about 150 m to about 850 m and displaced 8.9 ± 0.1 cubic kilometres, of which 6.85 ± 0.05 cubic kilometres was attributed to caldera collapse. | QUANTITATIVE | Supported |
| In the study’s mass-balance tests, the permissible carbonaceous CI contribution to the bulk silicate Earth was constrained below approximately 0.3% by ruthenium and below 2% by calcium. | QUANTITATIVE | Supported |

| Century-scale records and reactive-transport modelling indicate that agricultural liming acted as a net carbon sink in the Mississippi River Basin over the past century, after an initial emissions pulse and with a decadal lag. | QUANTITATIVE | Supported |
| The study estimated that current global carbon-budget calculations may underestimate the ocean carbon sink by 10 ± 5% because they omit rain effects. | QUANTITATIVE | Supported |
