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 …

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 …

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

• 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 …

In the tropics, the proportion of heavier water isotopes in precipitation is anticorrelated with
the precipitation amount. The physical processes underlying this so‐called amount effect are …

We review the history of the South American summer monsoon (SASM) over the past~ 2000
yr based on high-resolution stable isotope proxies from speleothems, ice cores and lake …

Three lines of evidence for abrupt tropical climate change, both past and present, are
presented. First, annually and decadally averaged δ18O and net mass-balance histories for …

We present simulations of water‐stable isotopes from the LMDZ general circulation model
(the LMDZ‐iso GCM) and evaluate them at different time scales (synoptic to interannual) …

The climate of the Last Glacial period (10,000 to 110,000 years ago) was characterized by
rapid millennial-scale climate fluctuations termed Dansgaard/Oeschger (D/O) and Heinrich …

In response to a request from Congress, Surface Temperature Reconstructions for the Last
2,000 Years assesses the state of scientific efforts to reconstruct surface temperature records …
