Holocene Forcing of the Indian Monsoon Recorded in a Stalagmite from Southern Oman
TLDR
A high-resolution oxygen-isotope record from a thorium-uranium–dated stalagmite from southern Oman reflects variations in the amount of monsoon precipitation, indicating that early Holocene monsoon intensity is largely controlled by glacial boundary conditions.
Insolation-driven changes in atmospheric circulation over the past 116,000 years in subtropical Brazil
TLDR
A high-resolution oxygen isotope record of a U/Th-dated stalagmite from subtropical southern Brazil, covering the past 116,200 years, finds that variations in rainfall source and amount are primarily driven by summer solar radiation, which is controlled by the Earth's precessional cycle.
Strong coherence between solar variability and the monsoon in Oman between 9 and 6 kyr ago
TLDR
A high-resolution record of oxygen isotope variations, for the period from 9.6 to 6.1 kyr before present, in a Th–U-dated stalagmite from Oman suggests that one of the primary controls on centennial- to decadal-scale changes in tropical rainfall and monsoon intensity during this time are variations in solar radiation.
Variable winter moisture in the southwestern United States linked to rapid glacial climate shifts
The last glacial period was characterized by large, rapid climate fluctuations. An analysis of a speleothem from New Mexico shows that the coldest conditions over Greenland coincide with increased
Orbitally driven east–west antiphasing of South American precipitation
The variations of tropical precipitation are antiphased between the hemispheres on orbital timescales. A comparison between a speleothem record of precipitation in northeast Brazil and rainfall
Solar forcing of Holocene climate: New insights from a speleothem record, southwestern United States
Holocene climate change has likely had a profound infl uence on ecosystems and culture. A link between solar forcing and Holocene climate, such as the Asian monsoon, has been shown for some regions,
Evidence for a widespread climatic anomaly at around 9.2 ka before present
[1] The 8.2 ka event was triggered by a meltwater pulse (MWP) into the North Atlantic and resultant reduction of the thermohaline circulation (THC). This event was preceded by a series of at least 14
Timing and structure of the 8.2 kyr B.P. event inferred from δ18O records of stalagmites from China, Oman, and Brazil
Oxygen isotope records of stalagmites from China and Oman reveal a weak summer monsoon event, with a double-plunging structure, that started 8.21 ± 0.02 kyr B.P. An identical but antiphased pattern
