Stable isotope ratios of hydrogen and oxygen have been applied to water cycle research for
over 60 years. Over the past two decades, however, new data, data compilations, and …

The measurement and simulation of water vapor isotopic composition has matured rapidly
over the last decade, with long‐term data sets and comprehensive modeling capabilities …

Reconstructing the history of tropical hydroclimates has been difficult, particularly for the
Amazon basin—one of Earth's major centres of deep atmospheric convection,. For example …

Precise characterization of hydroclimate variability in Amazonia on various timescales is
critical to understanding the link between climate change and biodiversity. Here we present …

Variations in speleothem oxygen-isotope values (δ18O) result from a complicated interplay
of environmental controls and processes in the ocean, atmosphere, soil zone, epikarst, and …

Observations on glacier extent from Ecuador, Peru and Bolivia give a detailed and
unequivocal account of rapid shrinkage of tropical Andean glaciers since the Little Ice Age …

The regional monsoons of the world have long been viewed as seasonal atmospheric
circulation reversal—analogous to a thermally-driven land-sea breeze on a continental …

• The sustained rate of increase over the past century in the combined radiative forcing from
the three well-mixed greenhouse gases carbon dioxide (CO2), methane (CH4), and nitrous …

A better understanding of the relative roles of internal climate variability and external
contributions, from both natural (solar, volcanic) and anthropogenic greenhouse gas forcing …

A proxy system model may be defined as the complete set of forward and mechanistic
processes by which the response of a sensor to environmental forcing is recorded and …
