Academician Chen Deliang’s Team of Tsinghua University Reveals That Climate Change and Inequality Intensify Global Migration PressureClimate change is emerging as one of the most severe human challenges of the 21st century, profoundly reshaping the global pattern of population migration. The frequent occurrence of extreme climate events exacerbates food, health, and water resource crises, forc...
Against the backdrop of global warming, tropical cyclones (TCs) are exhibiting complex responses to climate change. On the one hand, cyclone intensification rates are accelerating and rapid intensification events have increased markedly; on the other hand, the distribution of tropical cyclone lifetime maximum intensity (LMI) is undergoing systematic adjustments. These phenomena indicate that th...
Recently, Academician Chen Deliang from the Department of Earth System Science (DESS) at Tsinghua University, in collaboration with the Institute of Tibetan Plateau Research of the Chinese Academy of Sciences, Alibaba Group, China Electric Power Research Institute of State Grid Corporation of China, Global Energy Interconnection Group Co., Ltd. and other institutions, has developed HydroTrace, ...
Species interactions form the core of ecosystem functions and represent a key process shaping biodiversity patterns. Research on the interactions between frugivorous birds and fruiting trees in natural ecosystems is an important approach to understanding the mechanisms of cross-trophic species interactions and their ecological impacts. Compared with natural ecosystems, urban areas exhibit disti...
Remote Sensing Multimodal Large Model Wins "New Model" Innovation Achievement Award at China International Digital Economy ExpoRecently, the series of remote sensing multimodal large model developed by the research group led by Professor Huang Xiaomeng from the Department of Earth System Science (DESS) at Tsinghua University was awarded the "New Model" Innovation Achievement Award at the 2025 C...
Long-term, continuous, and spatially explicit monitoring of global livestock dynamics is fundamental to understanding issues related to food security, public health, ecological and environmental change, and sustainable development. Over the past decades, institutions such as the Food and Agriculture Organization of the United Nations (FAO) have accumulated extensive agricultural statistics. How...
Sea ice is a critical component of the climate system. The Marginal Ice Zone (MIZ), a key region for sea ice formation and decay, plays an indispensable role in the recent dramatic changes in Antarctic sea ice. Due to the harsh natural environment in the marginal ice zone, in-situ observations and datasets are extremely limited. Meanwhile, traditional remote sensing methods are not suitable for...
Soil moisture-precipitation coupling is a key aspect of land-atmosphere interactions. However, there are substantial disagreements among different climate models in simulating the strength of this coupling, and the underlying physical pathways—specifically, whether soil moisture affects precipitation through surface sensible heat (SH) or evapotranspiration (ET)—remain unclear. To address thes...
