J., Goosse, H., Goursaud, S., Masson-Delmotte, V., Moy, A., Neukom, R., Orsi, A., Sjolte, J., Steiger, N., Stenni, B., and Werner, M.: Assessing the robustness of Antarctic temperature reconstructions over the past two millennia using pseudoproxy and data assimilation experiments, Clim.

We use a new database of stable oxygen isotopes in ice cores compiled in the framework of Antarctica2k (Stenni et al., 2017) to constrain model ensembles derived from two simulations: one performed using ECHAM5-MPI-OM that covers the period 800-1999 CE with a horizontal resolution of 3.75° by 3.75° (Sjolte et al., 2018), and the other performed with ECHAM5-wiso, spanning 1871-2011 CE at 1.125° spatial resolution (Steiger et al., 2017). This latter simulation is available here.
Four netCDF files are available:
d18O_DA_ECHAM5-MPI-OM_1-2015.nc: data assimilation-based δ18O reconstructions using the model ensemble derived from ECHAM5-MPI-OM
ts_DA_ECHAM5-MPI-OM_1-2015.nc: data assimilation-based surface temperature reconstructions using the model ensemble derived from ECHAM5-MPI-OM
d18O_DA_ECHAM5-wiso_1-2015.nc: data assimilation-based δ18O reconstructions using the model ensemble derived from ECHAM5-wiso
ts_DA_ECHAM5-wiso_1-2015.nc: data assimilation-based surface temperature reconstructions using the model ensemble derived from ECHAM5-wiso
The variables included in the NetCDF files are:

El Niño–Southern Oscillation variability, teleconnection changes and responses to large volcanic eruptions since AD 1000
No full textThe El Niño–Southern Oscillation (ENSO) is the earth’s dominant mode of inter-
annual climate variability. It alternates between warm (El Niño) and cold (La Niña) states, with global impacts on climate and society. This study provides new ENSO reconstructions based on a large, updated collection of proxy records. We use a novel reconstruction approa ch that employs running principal components, which allows us to take covariance changes between proxy records into account and thereby identify periods of likely teleconnection changes. Using different implementations of the principal component analysis enables us to identify periods within the last millennium when quantifications of ENSO are most robust. These periods range from 1580 to the end of the 17th century and from 1825 to present. We incorporate an assessment of consistency among our new and existing ENSO reconstructions leading to five short phases of low agreement among the reconstructions between 1700 and 1786. We find a consistent spatial pattern of proxy covariance during these four phases, differing from the structure seen over the instrumental period. This pattern points towards changes in teleconnections in the west Pacific/Australasian region, compared to the present state. Using our new
reconstructions, we find a significant response of ENSO towards more La Niña-like conditions 3–5 years after major volcanic events. We further show that our new reconstructions and existing reconstructions largely agree on the state of ENSO during volcanic eruptions in the years 1695 and 1784, which helps put into perspective the climatic response to these events. During all other large volcan ic eruptions of the last 1000 years, there is no reconstruction coherency with regard to the state of ENSO
Australasian Temperature Reconstructions Spanning the Last Millennium
No full textMultiproxy warm season (September–February) temperature reconstructions are presented for the combined land–ocean region of Australasia (0º–50ºS, 110ºE–180º) covering 1000–2001. Using between 2 (R2) and 28 (R28) paleoclimate records, four 1000-member ensemble reconstructions of regional temperature are developed using four statistical methods: principal component regression (PCR), composite plus scale (CPS), Bayesian hierarchical models (LNA), and pairwise comparison (PaiCo). The reconstructions are then compared with a three-member ensemble of GISS-E2-R climate model simulations and independent paleoclimate records. Decadal fluctuations in Australasian temperatures are remarkably similar between the four reconstruction methods. There are, however, differences in the amplitude of temperature variations between the different statistical methods and proxy networks. When the R28 network is used, the warmest 30-yr periods occur after 1950 in 77% of ensemble members over all methods. However, reconstructions based on only the longest records (R2 and R3 networks) indicate that single 30- and 10-yr periods of similar or slightly higher temperatures than in the late twentieth century may have occurred during the first half of the millennium. Regardless, the most recent instrumental temperatures (1985–2014) are above the 90th percentile of all 12 reconstruction ensembles (four reconstruction methods based on three proxy networks—R28, R3, and R2). The reconstructed twentieth-century warming cannot be explained by natural variability alone using GISS-E2-R. In this climate model, anthropogenic forcing is required to produce the rate and magnitude of post-1950 warming observed in the Australasian region. These paleoclimate results are consistent with other studies that attribute the post-1950 warming in Australian temperature records to increases in atmospheric greenhouse gas concentrations
Characterization of pectin lyases on pectins and methyl oligogalacturonates
No full textPure saturated and unsaturated oligogalacturonic acids, including unsaturated monogalacturonic acid, were isolated and characterized. Their ultraviolet absorbance at 232 run, and their reactivities in the periodate thiobarbituric acid test and carbazole tests were studied. From these compounds methyl oligogalacturonates were prepared, which were used as model substrates.Pectin lyases (EC 4.2.99.8; poly-α-1,4-D-methyl-galacturonate lyase) were found to be very common in commercial 'pectinase' preparations. From each of three 'pectinase' preparations a pectin lyase was isolated free of other pectolytic enzymes. Their pH optimum, pH stability, isoelectric point and activation energy were determined. Information on the action of the enzymes on pectins with various degrees of esterification ( DE ) was obtained by kinetic studies, by determining the extent of degradation and by analysing the composition of the reaction mixtures. The breakdown mechanism on pectin and pattern of action on methyl oligogalacturonates was studied. Divalent cations were found to activate pectin lyase activity, their activation depended on the pH and DE. Literature on the isolation and characterization of oligogalacturonides and on pectin degrading enzymes is reviewed
Teleconnection stationarity, variability and trends of the Southern Annular Mode (SAM) during the last millennium
No full textThe Southern Annular Mode (SAM) is the leading mode of atmospheric interannual variability in the Southern Hemisphere (SH) extra-tropics. Here, we assess the stationarity of SAM spatial correlations with instrumental and paleoclimate proxy data for the past millennium. The instrumental period shows that temporal non-stationarities in SAM teleconnections are not consistent across the SH land areas. This suggests that the influence of the SAM index is modulated by regional effects. However, within key-regions with good proxy data coverage (South America, Tasmania, New Zealand), teleconnections are mostly stationary over the instrumental period. Using different stationarity criteria for proxy record selection, we provide new austral summer and annual mean SAM index reconstructions over the last millennium. Our summer SAM reconstructions are very robust to changes in proxy record selection and the selection of the calibration period, particularly on the multi-decadal timescale. In contrast, the weaker performance and lower agreement in the annual mean SAM reconstructions point towards changing teleconnection patterns that may be particularly important outside the summer months. Our results clearly portend that the temporal stationarity of the proxy-climate relationships should be taken into account in the design of comprehensive regional and hemispherical climate reconstructions. The summer SAM reconstructions show no significant relationship to solar, greenhouse gas and volcanic forcing, with the exception of an extremely strong negative anomaly following the AD 1257 Samalas eruption. Furthermore, reconstructed pre-industrial summer SAM trends are very similar to trends obtained by model control simulations. We find that recent trends in the summer SAM lie outside the 5–95% range of pre-industrial natural variability.Fil: Dätwyler, Christoph. University of Bern. Centre for Climate
