Welcome to i-Ecoclimatology Lab
Decoding the intricate interactions between ecosystems, water cycles, and climate to advance impact assessment and global mitigation strategies.
Our Research
Our research encompasses three core pillars: water cycle-climate interactions, ecosystem-climate interactions, and climate impacts & mitigation. By integrating Earth system models such as CESM and WRF, spatial multi-source data, and attribution analysis, we aim to uncover complex climate feedbacks and develop method-driven, actionable mitigation strategies.

Replacing downwelling shortwave radiation with net radiation as the energy indicator, the team finds in 16 CMIP6 models that water limitation on evapotranspiration does not increase significantly by 2100; earlier projections overestimated it by counting atmospheric water demand twice.
Global drought shows no detectable recent acceleration under climate warming
Using 11 global SPEI datasets built from six PET methods, the team shows that reported global drying is largely driven by the choice of evapotranspiration formulation, and that no statistically significant recent acceleration of global drought is detectable during 1981–2024.
Divergent impacts of climate interventions on China's north-south water divide
This study examines how climate interventions may produce different water-cycle responses across China's north and south, highlighting the need to consider regional trade-offs.
Tsinghua SIGS team led by Yuanchao Fan advances research on global warming and deadly heat stress
This study provides the first global-scale quantitative assessment of how outdoor humid heat, solar radiation, and physiological factors drive heat stress, revealing that previous research has severely underestimated the outdoor health risks of global warming.
