Human impact overwhelms long-term climate control of fire in the Yangtze River Basin since 3.0 ka BP

TL;DR: In this article, a set of sulfur isotope data for hand-picked pyrites (δ34Spyr) from the coarse fraction of bulk sediments, coupled with the contents of carbonate, total organic carbon (TOC) and nitrogen (TN), as well as δ13C values of the TOC, from sediments of core EC2005 on the inner shelf of the East China Sea (ECS) since 16.4

TL;DR: In this article, the authors measured the contents of total organic carbon (TOC), total sulfur (TS), and carbonate in the collected samples, and showed that a C/S ratio of 2.8 can effectively separate freshwater environments (river sediments and core sediments deposited before 13.1 ka), suggesting the initial impact of sulfate-enriched seawater on carbon and sulfur perseveration at ~13.1-11.0 ka.

TL;DR: In this article , the authors analyzed multiple indicators of core sediments obtained from the inner shelf of the East China Sea and found that the C/S ratio overlaps between tidal flat and inner shelf environments, but the relatively high content of pyrite aggregates and fine-grained sediments in the shelf sediments can effectively separate these two environments.

TL;DR: A solar forcing mechanism therefore may underlie at least the Holocene segment of the North Atlantic's “1500-year” cycle, potentially providing an additional mechanism for amplifying the solar signals and transmitting them globally.

TL;DR: A 5-year-resolution absolute-dated oxygen isotope record from Dongge Cave, southern China, provides a continuous history of the Asian monsoon over the past 9000 years, and shows that some, but not all, of the monsoon variability at these frequencies results from changes in solar output.

TL;DR: The recovery of a deep ice core from Dome C, Antarctica, that provides a climate record for the past 740,000 years is reported, suggesting that without human intervention, a climate similar to the present one would extend well into the future.
