Through year-round simulations of six IAPs (PM_2.5, formaldehyde, ozone, benzene, sulfur dioxide, and nitrogen dioxide) in residential buildings in Beijing, the energy-health nexus under different intervention scenarios was quantified. PM_2.5 was the dominant IAP. Implementation of intervention scenario P1 (PM_2.5 control threshold range of 1–5 μg/m³) resulted in average percentage reductions of 84.5 % in annual average concentrations across six IAPs and 36.7 % in associated disease burdens.

The intervention scenario P4 + B1 (PM_2.5 control threshold range of 25–35 μg/m³ and benzene control threshold range of 0.01–0.02 mg/m³) is the most cost-effective intervention scenario for Beijing.

The framework is driven by the latest version of the Soil and Water Assessment Tool Plus (SWAT+), with a dynamic reservoir operation module, and the CLIMEA-BCUD dataset (Climate Change for East Asia with Bias-Corrected UNet), a high-fidelity product derived from an ensemble of 19 CMIP6 GCMs. A thorough evaluation against benchmark station-level observations indicates a high degree of closeness of CLIMEA-BCUD in capturing historical precipitation and temperature variability (CC &gt; 0.9, NSE &gt; 0.85). A seasonal shift in monsoon rainfall patterns is observed in the future climate scenarios, with the peak moving from July to August. Additionally, more frequent moderate rainfall and prolonged wet spells are expected, intensifying flood potential.

The present study addresses this question on a panzootic and polymicrobial disease, the Pacific Oyster Mortality Syndrome (POMS). POMS, initiated by the herpesvirus OsHV-1 μVar, affects juveniles of <em>Magallana gigas</em>, which is the most widely cultured oyster species in the world.

Using an integrative multi-omics approach, we demonstrate that high temperature has a dual effect on oysters (1) inducing a metabolic reprogramming, creating a sub-optimal metabolic environment for viral infection and thereby limiting POMS development, and (2) enhancing the host's antiviral immune capabilities, both at a baseline level and in response to infection. Overall, these responses triggered at elevated temperature improve oyster survival against POMS.

The novelty of this research lies in the introduction of six tourism-specific indicators—Carbon Intensity (CI), Carbon Structure (CS), Average Revenue per Tourist (ART), Tourism Spread Ratio (TSR), Tourism Pressure Index (TPI), and Number of Hospitality Structures (NHS)—to decompose the drivers of CO₂ emissions and assess their dynamic interaction with tourism growth. Empirical findings indicate that CI and ART were the primary contributors to emissions reductions accounting for −6.5 Mt. and − 3.9 Mt. respectively, consistent with previous evidence on structural and technological improvements. However, emissions were increasingly influenced by spatial concentration and infrastructure growth, as captured by NHS (+3.9 Mt) and TSR (+1.6 Mt). The Tapio analysis reveals heterogeneous decoupling trajectories among member states in the period 2008–2022, with strong decoupling observed in countries such as France, Portugal, and Sweden, while others experienced coupling or negative decoupling patterns. Overall, a recessive decoupling, index equal to 1.052, is estimated for EU in the period 2008–2022.
