By: S. B. Wilmes; T. F. Stocker; C. C. Raible

Description: Climate and Environmental Physics, University of Bern, Bern, Switzerland. To increase the sparse knowledge of long-term Southern Hemisphere (SH) climate variability, we assess an ensemble of 4 transient simulations over the last 500 yr performed with a state-of-the-art atmosphere ocean general circulation model. The model is forced with reconstructions of solar irradiance, greenhouse gas (GHG) and volcanic aerosol concentrations. A 1990 control simulati...

Description: LOCEAN-IPSL UMR 7159 CNRS-IRD MNHN-UPMC, Case 100, Université Pierre et Marie Curie, 4 place Jussieu, 75252 Paris Cedex 05, France. The oceanic response to volcanic eruptions over the last 1000 years is investigated with a focus on the North Atlantic Ocean, using a fully coupled AOGCM forced by a realistic time series of volcanic eruptions, total solar irradiance (TSI) and atmospheric greenhouse gases concentration. The model simulates little response to...

By: M. Wagreich

Description: Department of Geodynamics and Sedimentology, Center for Earth Sciences, University of Vienna, Austria. The Coniacian–Santonian time interval is the inferred time of oceanic anoxic event 3 (OAE 3), the last of the Cretaceous OAEs. A detailed look on the temporal and spatial distribution of organic-rich deposits attributed to OAE 3 suggests that black shale occurrences are restricted to the equatorial to mid-latitudinal Atlantic and adjacent basins, shelve...

By: J.-l. De Beaulieu; O. Peyron; L. Bernardo; E. Brugiapaglia; B. Vannière; M. Magny; S. Joannin

Description: CNRS USR3124 MSHE Ledoux, Besançon, France. A high-resolution pollen record from Lake Trifoglietti in Calabria (Southern Italy) provides new insights into the paleoenvironmental and palaeoclimatic changes which characterise the Holocene period in the Southern Italy. The chronology is based on 11 AMS radiocarbon dates from terrestrial macro-remains. The Holocene history of the vegetation cover shows the persistence of an important and ...

By: R. Caballero; N. Diffenbaugh; M. Huber; A. Goldner

Description: Earth and Atmospheric Sciences, Purdue University, USA. Substantial evidence exists for wetter-than-modern continental conditions in past warm climates. This is in apparent conflict with the robust global prediction for future climate change of a northward expansion of the subtropical dry zones that should drive aridification of many semiarid regions. Areas of expected aridification include much of Western North America, where extensive p...

Description: Department for Earth Science and Bjerknes Centre for Climate Research, University of Bergen, P.O. Box 7803, 5020 Bergen, Norway. Reconstructions of the late-Holocene climate rely heavily upon proxies that are assumed to be accurately dated by layer counting, such as measurements of tree rings, ice cores, and varved lake sediments. Considerable advances could be achieved if time-uncertain proxies were able to be included within these multiproxy recons...

By: R. Rondanelli; R. S. Lindzen

Description: Department of Geophysics, University of Chile, Santiago, Chile. Goldblatt and Zahnle (2011) raise a number of issues related to the possibility that cirrus clouds can provide a solution to the faint young sun paradox. Here, we argue that: (1) climates having a lower than present mean surface temperature cannot be discarded as solutions to the faint young sun paradox, (2) the detrainment from deep convective clouds in the tropics is a well-established ph...

Description: Centre for Ice and Climate, Niels Bohr Institute, University of Copenhagen, Copenhagen, Denmark. Whereas ice cores from high accumulation sites in coastal Antarctica clearly demonstrate annual layering, it is debated whether a seasonal signal is also preserved in ice cores from lower accumulation sites further inland and particularly on the East Antarctic Plateau. In this study, we examine five metres of early Holocene ice from the Dome Fuji (DF) ice core ...

Description: Departamento Astrofísica y Ciencias de la Atmósfera, Universidad Complutense, Madrid, Spain. The study of Greenland ice cores revealed two decades ago the abrupt character of glacial millennial-scale climate variability.

Central East Antarctic ice cores preserve stratigraphic records of mineral dust originating from remote sources in the Southern Hemisphere, and represent useful indicators of climatic variations on glacial-interglacial time scales. The peripheries of the East Antarctic Ice Sheet, where ice-free areas with the potential to emit dust exist, have been less explored from this ...

Description: State Key Laboratory of Loess and Quaternary Geology, Institute of Earth Environment, CAS, Xi'an, 710075, China. We synthesized high-resolution precisely-dated stalagmite records and historical document records from north central China to reconstruct a decadal resolution precipitation record during the last 1800 yr (190–1980 AD). Several notable wet intervals were identified: 190s–290s, 560s–850s, 920s–1000s, 1090s–1130s, 1880s–1910s. The most remarkabl...

Fossil pollen records provide key insight into the sensitivity of terrestrial ecosystems to climate change at longer time scales.

It is suggested that the uplift of Himalaya-Tibetan Plateau enhanced interior aridity in East Asia and resulted in development of middle latitude gobi and sandy deserts and accumulation of the eolian sediments in the Chinese Loess Plateau. Therefore, estimation of the provenance for eolian sediments in the Chinese Loess Plateau is critical to reconstruct the environmental chan...

Description: Institute for Atmospheric and Climate Science, ETH Zürich, Switzerland. The variability and trend of Arctic sea ice since the mid 1970s is well documented and linked to rising temperatures. However, much less is known for the first half of the 20th century, when the Arctic also underwent a period of strong warming. For studying this period in atmospheric models, gridded sea ice data are needed as boundary conditions. Current data sets (e.g., HadISST) pr...
