6.Recent global-warming hiatus tied to equatorial Pacific surface cooling
Yu Kosaka & Shang-Ping Xie
Nature 501, 403–407 (19 September 2013) doi:10.1038/nature12534

Despite the continued increase in atmospheric greenhouse gas concentrations, the annual mean global temperature has not risen in the twenty-first century. Using radiative forcing and SST in tropical Pacific as inputs of the climate model, they concluded that the hiatus in global warming is part of natural climate variability, tied specifically to a La-Nina-like decadal cooling. Although, similar decadal hiatus events may occur in the future, the multi-decadal warming trend is very likely to continue with greenhouse gas increase.

7.Rapid cross-density ocean mixing at mid-depths in the Drake Passage measured by tracer release
Andrew J. Watson, James R. Ledwell, Marie-José Messias, Brian A. King, Neill Mackay, Michael P. Meredith, Benjamin Mills & Alberto C. Naveira Garabato

Nature 501, 408–411 (19 September 2013) doi:10.1038/nature12432

Diapycnal mixing of mid-depth(~1.500 meters) waters undergoes a sustained 20-fold increase as the Antarctic Circumpolar Current flows through the Drake Passage. The great majority of the diapycnal flux is the result of interaction with restricted regions of rough ocean-floor topography.

8.Causes of the Cambrian Explosion
M. Paul Smith and David A. T. Harper Science20September2013:1355-1356.[DOI:10.1126/science.1239450]

The rapid diversification of animal species in the early Cambrian was the result of a range of interacting biotic and abiotic processes.

11.Origin and provenance of spherules and magnetic grains at the Younger Dryas boundary
Yingzhe Wu, Mukul Sharma, Malcolm A. LeCompte, Mark N. Demitroff, and Joshua D. Landis
PNAS 2013 110 (38) E3557-E3566; published ahead of print September 5, 2013, doi:10.1073/pnas.1304059110


They analyzed bulk sediment and magnetic grains / microspherules collected from the Younger Dryas boundary. The Os ratios of the spherules and their leachates shows that the spherules are likely terrestrially derived. The rare earth element patterns and Sr and Nd isotopes of the spherules indicate that their source lies in 1.5Ga Quebecia terrain in the northeastern North America.

12.Sea surface height evidence for long-term warming effects of tropical cyclones on the ocean
Wei Mei, François Primeau, James C. McWilliams, and Claudia Pasquero PNAS 2013 110 (38) 15207-15210; published ahead of print August 6, 2013, doi:10.1073/pnas.1306753110


13.Model projections of atmospheric steering of Sandy-like superstorms
Elizabeth A. Barnes, Lorenzo M. Polvani, and Adam H. Sobel
PNAS 2013 110 (38) 15211-15215; published ahead of print September 3, 2013, doi:10.1073/pnas.1308732110



14.End of the Little Ice Age in the Alps forced by industrial black carbon
Thomas H. Painter, Mark G. Flanner, Georg Kaser, Ben Marzeion, Richard A. VanCuren, and Waleed Abdalati

PNAS 2013 110 (38) 15216-15221; published ahead of print September 3, 2013, doi:10.1073/pnas.1302570110


Glacier in the European Alps began to retreat abruptly from mid-19th century. Radiative forcing by increasing deposition of industrial black carbon to snow represent the driver of the abrupt retreat, which is consistent with existing temperature and precipitation records and reconstructions.

15.Bioclimatic and physical characterization of the world’s islands
Patrick Weigelt, Walter Jetz, and Holger Kreft
PNAS 2013 110 (38) 15307-15312; published ahead of print September 3, 2013, doi:10.1073/pnas.1306309110
