Since the establishment of the IAEA-WMO precipitation-monitoring network in 1961, it has
been observed that isotope ratios in precipitation ( δ H 2 and δ O 18 ) generally decrease from …

Although important for riverine solute and nutrient fluxes, the connections between
biogeochemical processes and subsurface hydrology remain poorly characterized. We investigate …

There remains substantial debate concerning the relative roles of tectonics and of global
climate in pacing the evolution of aridity in Central Asia over the Cenozoic. Tibetan Plateau uplift…

The hydroclimate history of North America includes the formation and desiccation of large
inland lakes and the growth and ablation of glaciers throughout the Quaternary period. At the …

Current understanding of the long-term carbon cycle posits that Earth's climate is stabilized
by a negative feedback involving CO 2 consumption by chemical weathering of silicate …

Recent studies have suggested that thermodynamic limitations on chemical weathering
rates exert a first-order control on riverine solute fluxes and by extension, global chemical …

Central Asia has become increasingly arid during the Cenozoic, though the mechanisms
behind this aridification remain unresolved. Much attention has focused on the influence and …

The mid-Pliocene warm period (MPWP, 3.3–2.9 Ma), with reconstructed atmospheric pCO 2
of 350–450 ppm, represents a potential analogue for climate change in the near future. …

The size distribution of lakes records the competition between precipitation delivery and
evaporation. Lakes were abundant in the terminally draining basins of the western United States …

The new excess term of the triple oxygen isotope composition in meteoric water, expressed
as ∆′ 17 O, is conceived to track the component of kinetic fractionation in the water cycle, …
