Climate of the Past

1.Stable isotopic evidence of El Niño-like atmospheric circulation in the Pliocene western United States
M. J. Winnick, J. M. Welker, and C. P. Chamberlain
Clim. Past, 9, 903-912, 2013

   Compare Pliocene oxygen isotope profiles of the pedogenic carbonates across the western US to modern isotopic anomalies in precipitation between phases of the ENSO
   The evolution of atmospheric circulation through the Pliocene resembled the modern transition from El Nino to neutral phase of ENSO
   The Plio-Pleistocene boundary is characterized by the initiation and rapid expansion of glaciation in NH
   northward migration of the westerly storm track through the late Pliocene with development of the cold tongue in the east equatorial Pacific
   after the Plio-Pleistocene boundary, the poleward migration of the subtropical jet with the decay of El Nino-like SSTs and development of the EEP cold tongue

2.Climate and vegetation changes during the Lateglacial and early–middle Holocene at Lake Ledro (southern Alps, Italy)

Clim. Past, 9, 913-933, 2013

   lake sediment core
   pollen-based vegetation and climate reconstruction, lake levels, magnetic susceptibility and XRF measurements
   pollen record is compared with vegetation records to trace the history of tree species distribution
the period between ca. 5700 and ca. 4100 cal BP is considered as a transition period to colder and wetter conditions

3. Climatic impacts of fresh water hosing under Last Glacial Maximum conditions: a multi-model study
M. Kageyama, U. Merkel, B. Otto-Bliesner, M. Prange, A. Abe-Ouchi, G. Lohmann, R. Ohgaito, D. M. Roche, J. Singarayer, D. Swingedouw, and X Zhang
Clim. Past, 9, 935-953, 2013

   11 simulations run with 6 different climate models
   common features: the cooling over the North Atlantic, extending along the subtropical gyre in the tropical North Atlantic, the southward shift of the Atlantic ITCZ, the weaking of the African and Indian monsoons
   difference from model to model: pathways for the teleconnections between the AMOC/North Atlantic region and the African and Indian monsoon regions  

4. Model sensitivity to North Atlantic freshwater forcing at 8.2 ka
C. Morrill, A. N. LeGrande, H. Renssen, P. Bakker, and B. L. Otto-Bliesner
Clim. Past, 9, 955-968, 2013
   4 simulations of the 8.2ka event
   same fresh water forcing applied to either the Husdon Bay or Labrador Sea
   freshwater plus induced a decadal-mean slowdown of 10-25% in the AMOC and caused a large-scale pattern of climate anomalies
   matched proxy evidence for cooling in NH and southward shift of ITCZ

15. Recent warming at Summit, Greenland: Global Context and Implications
Daniel McGrath,William Colgan, Nicolas Bayou, Atsuhiro Muto, Konrad Steffen
DOI: 10.1002/grl.50456
   the annual mean near-surface air temperature increased at 0.09±0.01/a over the 1982-2011
   warming has been greatest in the winter season during 1987-2011 although the implications of summer warming are more acute
   the annual maximum elevation of the equilibrium line and dry snow line has risen at 44 and 35m/a over the past 15 and 8 years
   the dry snow facies of the Greenland Ice Sheet will transition to percolation facies with 95% confidence
