Abstract Partly laminated sediments were sampled from the brine-filled, anoxic Shaban Deep basin in the northern Red Sea. At about 4200 cal yr BP more than two millennia of anoxic sedimentation is replaced by a sub-oxic facies strongly suggesting the episodic absence of the brine. At the same time stable oxygen isotopes from surface dwelling foraminifera show a sharp increase (within less than 100 yr) pointing to a strong positive salinity anomaly at the sea surface. This major evaporation… 
Weak monsoon event at 4.2 ka recorded in sediment from Lake Rara, Himalayas
Abstract The strength of the Indian summer monsoon varied significantly on centennial- to millennial timescales during the Holocene. Among these variations, a weak summer monsoon event occurred
Late Holocene Paleoclimate reconstruction of the northern Gulf of Aqaba using foraminifera as a proxy
A multiproxy analyses of sediment from a 4.3 m core extracted from 25 m water depth on the shelf of the northern Gulf of Aqaba suggest shifts in depositional environments over the past 4000 yrs.
Late Quaternary climatic changes in the eastern Kumaun Himalaya, India, as deduced from multi-proxy studies
Abstract An event of neotectonic activity on an NE–SW trending subsidiary fault in the zone of E–W running intracrustal boundary thrust (South Almora Thrust) in the Champawat district of eastern
Late Holocene hydrology inferred from lacustrine sediments of Laguna Cháltel (southeastern Argentina)
Abstract Hydrological changes that occurred during the last 4700 years have been reconstructed using multi-proxy analyses of sediment cores from the volcanic crater lake of Laguna Chaltel (50°S,
Precise timing of abrupt increase in dust activity in the Middle East coincident with 4.2 ka social change
TLDR
An Iranian stalagmite record spanning 5.2 ka to 3.7 ka is presented, dated with 25 U/Th ages that provide an average age uncertainty of 31 y (1σ), and finds two periods of increased Mg/Ca, beginning abruptly at 4.51 and 4.26 ka, and lasting 110 and 290 y, respectively.
The 4.2 ka BP event in the Levant
Abstract. The 4.2 ka BP event is defined as a phase of environmental stress characterized by severe and prolonged drought of global extent. The event is recorded from the North Atlantic through

Climatic and environmental evolution of Lake Iznik (NW Turkey) over the last ∼4700 years
Abstract Magnetic susceptibility, geochemistry, mineralogy and palynology of sediments from Lake Iznik in Northwestern Anatolia, Turkey, provide a 4700 year record of climatic trends and events. The
Speleothem Evidence for Megadroughts in the SW Indian Ocean during the Late Holocene
Abstract. The 4.2 ka BP event is widely described as a 200–300 years long interval of major climate anomaly (typically, arid and cooler conditions potentially across the globe), which defines the
Mid–late Holocene event registered in organo-siliciclastic sediments of Lagoa Salgada carbonate system, southeast Brazil
Abstract. The formation of the Paraíba do Sul river delta plain on the coast of Rio de Janeiro state, Brazil, gave rise to diverse lagoons formed under different sea level regimes and climate

Rainy periods and bottom water stagnation initiating brine accumulation and metal concentrations: 1. The Late Quaternary
A working hypothesis is proposed to account for the present accumulation of brines in isolated pockets of the ocean floor and for the formation of the underlying organic and metal-rich sediments.
Hydrographic structure of brine-filled deeps in the Red Sea—new results from the Shaban, Kebrit, Atlantis II, and Discovery Deep
Abstract Hydrographic profiles with CTD and water samples from four brine-filled deeps in the Red Sea (Shaban, Kebrit, Atlantis II and Discovery Deep) were taken during the Meteor 31/2 expedition in
Climate change at the 4.2 ka BP termination of the Indus valley civilization and Holocene south Asian monsoon variability
[1] Planktonic oxygen isotope ratios off the Indus delta reveal climate changes with a multi-centennial pacing during the last 6 ka, with the most prominent change recorded at 4.2 ka BP. Opposing
Mediterranean Moisture Source for an Early-Holocene Humid Period in the Northern Red Sea
TLDR
It is concluded that Afro-Asian monsoonal rains did not cross the subtropical desert zone during the early to mid-Holocene and is best explained by enhancement and southward extension of rainfall from Mediterranean sources.
Renewal of deep water in the Red Sea during 1982–1987
Between October 1982 and May 1983 the deep water in the northern Red Sea was ventilated through slope convection. The deep water became cooler, fresher, and more oxygenated. Dense bottom water formed
Isotopic Composition and Origin of the Red Sea and Salton Sea Geothermal Brines
Abstract. Deuterium and oxygen-18 measurements show that the Red Sea and Salton Sea brines are the results of a single process, the leaching of sediments by surface water circulating downward to a
Climate and the collapse of Maya civilization.
TLDR
A seasonally resolved record of titanium shows that the collapse of Maya civilization in the Terminal Classic Period occurred during an extended regional dry period, punctuated by more intense multiyear droughts centered at approximately 810, 860, and 910 A.D.
Persistent Solar Influence on North Atlantic Climate During the Holocene
TLDR
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.
