The El Nino/Southern Oscillation (ENSO) system is a prominent component of interannual climate variability, and the Southern Index (SOI) primary measure state ENSO ([1][1]). Here, we present evidence that ENSO-related changes in terrestrial carbon cycle can

Accurately predicting future tropical cyclone risk requires understanding the fundamental controls on dynamics. Here we present an annually-resolved 450-year reconstruction of western Caribbean activity developed using a new coupled carbon and oxygen isotope ratio technique in exceptionally well-dated stalagmite from Belize. Western peaked at 1650 A.D., coincident with maximum Little Ice Age cooling, decreased gradually until end record 1983. Considered other reconstructions, suggests that...
Abstract The progress of science is tied to the standardization measurements, instruments, and data. This especially true in Big Data age, where analyzing large data volumes critically hinges on being standardized. Accordingly, lack community‐sanctioned standards paleoclimatology has largely precluded benefits advances field. Building upon recent efforts standardize format terminology paleoclimate data, this article describes Paleoclimate Community reporTing Standard (PaCTS), a crowdsourced...
Abstract An annually laminated stalagmite from the northern Yucatán Peninsula contains mud layers 256 cave flooding events over 2240 years. This new conservative proxy for paleotempestology recorded with a recurrence interval of 8.3 years during twentieth century, greatest frequency century and least frequent seventeenth century. Tropical cyclone (TC) are unlikely to flood drought when water table is depressed. Applying TC masking Chaac paleorainfall reconstruction suggests that severity...
Extending the meteorological record back in time can offer critical data for assessing tropical cyclone-climate links. While paleotempestology, study of ancient storms, provide a more realistic view past 'worst case scenarios', future environmental conditions may have no analogues paleoclimate record. The primary value paleotempestology proxy records arises from their ability to quantify climate–tropical cyclone interactions by sampling activity during pre-historic periods with wider range...
The anomalously low oxygen isotope ratio (δ 18 O values) of tropical cyclone rainfall can transfer proxy information about past activity to stalagmite records. Isotopically distinct stormwater reaches the growing crystal surface as a coherent slug, or after attenuation by mixing with isotopically normal vadose groundwaters. A high‐resolution micromilled stable record from Belize shows that residual water Hurricane Mitch masked major El Niño event. On decadal time scales, measured δ values...

Rationale Dacryoconarids are extinct marine zooplankton known from abundant, globally distributed calcite microfossils in the Devonian, but their shell stable isotope composition has not been previously explored. Devonian stratigraphy is currently limited to less common invertebrates or bulk rock analyses of uncertain provenance. As with Cenozoic planktonic foraminifera, isotopic analysis dacryoconarid shells could facilitate higher‐resolution, geographically widespread records...
Earth System Science is an exceptionally interdisciplinary field requiring knowledge and skills from multiple scientific disciplines. Many important questions lie at the intersection of traditional disciplines require a systems level approach. The emerging educational challenge to train next generation scientists address these topics. Here, we describe development, delivery, assessment new course in designed for advanced undergraduates beginning graduate students. was meet specific learning...
