Drier and warmer climates have allowed fires to increasingly burn carbon-dense peatland ecosystems. Here we document a 2025 Scottish megafire in the UK, which spread rapidly and burned severely across peatlands in Scotland with anomalously ...

Lake sediment heatwaves, driven by rising global temperatures, pose emerging threats to freshwater ecosystems by altering sediment thermal regimes and intensifying sediment biogeochemical processes. Here we present a global-scale assessment...
The global distribution of CO2-rich magmas is determined by lithospheric thickness [0.03%]

Metasomatized lithospheric mantle plays a critical role in the petrogenesis of CO2-rich magmas, which are important hosts of rare-earth element deposits. However, the relationship between the structure of the lithosphere and the global dist...

Natural estuarine morphology exerts strong control over tidal propagation. Human activities, such as dredging and land reclamation, modify the natural geometry, altering tidal dynamics and the ecosystems linked to them. Here we analyse chan...
Entrained debris records regrowth of the Greenland Ice Sheet after the last interglacial [0.03%]
冰川记录显示上一个间冰期后格陵兰冰盖的再度扩张

Radio echo sounding data reveal intensely deformed structures deep within the northern Greenland Ice Sheet. The geometry of these structures has been well studied, but their physical properties remain poorly understood. Here we investigate ...
Continental evolution influenced by relamination of deeply subducted continental crust [0.03%]
深俯冲大陆地壳再擦世对大陆演化的影響

Daniel Gómez-Frutos et al.
Post-collisional magmatism has played a critical role in modifying the continental crust since the Archaean, 3 billion years ago. The dual mantle-crust signature of calc-alkaline post-collisional magmas requires a hybrid source involving bo...
Water isotope-temperature relationship variability across Antarctica set by atmospheric circulation [0.03%]
南极洲水同位素温度关系的变化由大气环流决定

Water isotopes serve as tracers of hydrological processes and as proxies for past climates archived in ice cores. The isotopic signal is acquired throughout the hydrological cycle-through evaporation over the oceans, precipitation, which oc...

Oceanic submesoscale currents dominate the vertical exchanges of heat, biological nutrients and carbon between the shallow and the deep ocean and strongly influence the lateral dispersion of biogeochemical tracers and pollutants. Observing ...

The boreal forest biome is warming rapidly, impacting disturbance regimes and global climate. Boreal forest fires have intensified, initiating both climate warming (positive) and climate cooling (negative) impacts across spatial and tempora...
Millennial-aged peat carbon outgassed by large humic lakes in the Congo Basin [0.03%]
刚果盆地大型腐泥湖释放万年泥炭碳

Travis W Drake et al.
Congo Basin lakes Mai Ndombe and Tumba are major CO2 sources. Here we show that their dissolved inorganic carbon is some 2,170-3,515 14C years old and partially (39-40%) originates from the surrounding peatlands. This implies a loss pathway...
