TL;DR: In this paper, a multidecadal-scale Southern Oscillation Index for the past 2,000 years has been derived, and it is shown that the Medieval Warm Period (similar to AD 800-1300) was characterized by a negative index, which indicates more El Nino-dominated conditions, whereas during the Little Ice Age, a La Nina-dominated condition prevailed.

TL;DR: In this paper, a modified high-volume sampler that pulls air through a quartz filter and a polyurethane foam plug (PUF) was analyzed for particulate phase and gas phase polycyclic aromatic hydrocarbons (PAHs) in the North Pacific Ocean and adjacent Arctic region.

TL;DR: Hydrological reconstructions from Cattle Pond, Dongdao Island of the South China Sea, where multi-decadal rainfall and downcore grain size variations are correlated to the Southern Oscillation Index during the instrumental era show that this site received less precipitation during relatively warm periods.

TL;DR: The PBDE levels exhibited a decreasing trend from the mid- to high-latitudinal regions of the North Pacific Ocean, probably resulting from dilution, deposition, and decomposition of PBDEs during long-range transport of air masses, and was consistent with the hypotheses of global fractionation.

TL;DR: In this article, the authors used a detailed 14,000-year record reconstructing vegetation variations from a strategically selected crater lake from Northeast China, as well as a compilation of previous paleoclimatic studies, to show that the HO began around 6,000 Cal a BP in Northeast China.
