Since 1980, anthropogenic emissions of ozone precursors have decreased in developed regions, but increased in developing regions, particularly East and South Asia, redistributing emissions equatorwards1-4. Modeling studies have shown that t...
Interannual variations in meltwater input to the Southern Ocean from Antarctic ice shelves [0.03%]

Ocean-driven basal melting of Antarctica's floating ice shelves accounts for about half of their mass loss in steady-state, where gains in ice shelf mass are balanced by losses. Ice shelf thickness changes driven by varying basal melt rates...
Heavy iron isotope composition of iron meteorites explained by core crystallization [0.03%]
铁陨石中较重的铁同位素组成可通过铁核结晶得到解释

Similar to Earth, many large planetesimals in the Solar System experienced planetary-scale processes such as accretion, melting, and differentiation. As their cores cooled and solidified, significant chemical fractionation occurred due to s...
"Reduction of tree cover in West African woodlands and promotion in semi-arid farmlands" [0.03%]
"西非林地的树木覆盖减少和半干旱农区的树木促进"

Martin Brandt et al.
Woody vegetation in farmland acts as a carbon sink and provides ecosystem services for local people, but no macro-scale assessments of the impact of management and climate on woody cover exists for drylands. Here we make use of very high sp...
Integrative analysis of desert dust size and abundance suggests less dust climate cooling [0.03%]
综合分析沙漠尘埃的尺寸和数量表明其气候冷却作用较弱

Desert dust aerosols affect Earth's global energy balance through interactions with radiation1,2, clouds3,4, and ecosystems5. But the magnitudes of these effects are so uncertain that it remains unclear whether atmospheric dust has a net wa...
Lunar soil hydration constrained by exospheric water liberated by meteoroid impacts [0.03%]
月球土壤受流星体撞击释放出的逃逸层水汽的制约而发生脱水现象

Analyses of samples from the Apollo missions suggest that the Moon formed devoid of native water. However, recent observations by Cassini, Deep Impact, Lunar Prospector and Chandrayaan-1 indicate the existence of an active water cycle on th...

The abundance and distribution of water within Mars through time plays a fundamental role in constraining its geological evolution and habitability. The isotopic composition of martian hydrogen provides insights into the interplay between d...

During terrestrial differentiation, the relatively small amount of phosphorus that migrated to the lithosphere was incorporated into igneous rock, predominantly in the form of basic calcium orthophosphate (Ca10(PO4)6(OH,F,Cl)2, apatite). Ye...

Global-scale glacier shrinkage is one of the most prominent signs of ongoing climatic change. However, important differences in glacier response exist at the regional scale, and evidence has accumulated that one particular region stands out...

For approximately the first 2 billion years of Earth history, atmospheric oxygen levels were extremely low. It wasn't until at least half a billion years after the evolution of oxygenic photosynthesis, perhaps as early as 3 billion years ag...
