Not a big deal after all Do volcanic eruptions affect El Niño–Southern Oscillation (ENSO) variability? Models indicate that sulfate aerosols resulting from large eruptions can initiate an El Niño–like response in the tropical Pacific, but observations have not shown evidence of such behavior. Dee et al. present an oxygen-isotope time series of fossil corals from the central tropical Pacific to investigate ENSO's response to large volcanic eruptions during the past millennium. They found a weak…

Hundreds of coral paleoclimate records have been developed over the past several decades, significantly extending the instrumental record and improving our understanding of tropical climate

Global hydroclimatic response to tropical volcanic eruptions over the last millennium

It is found that past eruptions caused severe drying in tropical Africa and across Central Asia and the Middle East and significantly wetter conditions over Oceania and the South American monsoon region, some of which persisted for more than a decade or longer.

Global tree-ring response and inferred climate variation following the mid-thirteenth century Samalas eruption

The largest explosive volcanic eruption of the Common Era in terms of estimated sulphur yield to the stratosphere was identified in glaciochemical records 40 years ago, and dates to the

Response to Comment on “No consistent ENSO response to volcanic forcing over the last millennium”

Although observational support for a dynamical response linking volcanic cooling to El Niño remains ambiguous, Robock raises some important questions about the study that are addressed here.

Do Southern Hemisphere tree rings record past volcanic events? A case study from New Zealand

. Much of our knowledge about the impacts of volcanic eruptions on climate comes from proxy records. However, little is known about their impact on the low to mid-latitudes of the Southern

Quantifying the contribution of forcing and three prominent modes of variability on historical climate

. Climate models can produce accurate representations of the most important modes of climate variability, but they cannot be expected to follow their observed time-evolution. This makes direct

On the Additivity of Climate Responses to the Volcanic and Solar Forcing in the Early 19 th Century

. The early 19th century was the coldest period over the past 500 years, when strong tropical volcanic events and a solar minimum coincided. The 1809 unidentified eruption and the 1815 Tambora

Decline in Etesian winds after large volcanic eruptions in the last millennium

Abstract. The northerly Etesian winds are a stable summertime circulation system in the eastern Mediterranean, emerging from a steep pressure gradient between the central Europe and Balkans



Direct Interactions between the Paf1 Complex and a Cleavage and Polyadenylation Factor Are Revealed by Dissociation of Paf1 from RNA Polymerase II

It is found that the cleavage and polyadenylation factor Cft1 requires the Pol II-associated form of the Paf1 complex for full levels of interaction with the serine 5-phosphorylated form of Pol II when the Pf1 complex is dissociated from Pol II.

Adult age differences in memory performance: tests of an associative deficit hypothesis.

An associative hypothesis to explain and predict older adults' deficient explicit episodic memory performance was outlined and tested and four experiments are reported that provide a converging validity and a discriminant validity to the hypothesis.

Sacral hydatid cysts with intrapelvic extension presenting as herniated intervertebral disc

Two type V myosins with non-overlapping functions in the fission yeast Schizosaccharomyces pombe: Myo52 is concerned with growth polarity and cytokinesis, Myo51 is a component of the cytokinetic actin ring.

The fission yeast genome project has identified five myosin genes and cells deleted for myo51(+) show normal morphology and growth rates whereas deletion of myo52(+) results in a partial loss of cell polarity, slow growth and cytokinetic defects.

El Niño/Southern Oscillation and tropical Pacific climate during the last millennium

Fossil-coral oxygen isotopic records from Palmyra Island are splice together to provide 30–150-year windows of tropical Pacific climate variability within the last 1,100 years, implying that the majority of ENSO variability over the last millennium may have arisen from dynamics internal to the ENSo system itself.

Enhanced El Niño–Southern Oscillation Variability in Recent Decades

The El Niño–Southern Oscillation (ENSO) represents the largest source of year‐to‐year global climate variability. While Earth system models suggest a range of possible shifts in ENSO properties under

Intercolony δ18O and Sr/Ca variability among Porites spp. corals at Palmyra Atoll: Toward more robust coral‐based estimates of climate

Quantitative estimates of natural climate variability are required to detect anthropogenic climate trends in the tropical Pacific; however, instrumental records from this region are too short and

A French-Canadian version of the practitioner and organizational telehealth readiness assessment tool is developed and validated and it is shown that it can be used with all kinds of telehealth projects and with different groups of participants.
