A high resolution absolute dating holocene and deglacial asian
Terrestrial deglacial warming therefore lagged behind marine changes by ca. Its timing coincided with an abrupt cold/warm and dry/wet transition observed in the Chinese cave stalagmites (29, 30) and in a Greenland ice core (31).
The marine system in this region mainly consists of the Kuroshio Current (21, 22), which flows north on the western side of the North Pacific Ocean, analogous to the Gulf Stream in the North Atlantic Ocean.
On land, the deglacial stage was characterized by rapid warming, as reflected by paleovegetation, and it began ca. The epicontinental climate system is characterized by seasonal alterations of the East Asian summer and winter monsoons (24).
15 ka BP, consistent with the timing of the last deglacial warming in Greenland. The ECS receives massive amounts of terrestrial sediments [about 2 × 10 tons/y (a)] transported by the Yangtze River and other rivers from the surrounding regions (25).
Just within the last 5 months, 58 more papers and 80 new graphs have been published that continue to undermine the popularized conception of a slowly cooling Earth temperature history followed by a dramatic hockey-stick-shaped uptick, or an especially unusual Yes, some regions of the Earth have been warming in recent decades or at some point in the last 100 years.
Some regions have been cooling for decades at a time.
Based on 33 U/Th dates and 1020 oxygen isotopic data from stalagmite Y1 from Yamen Cave, Guizhou Province, China, a record of the Asian Summer Monsoon (ASM) was established.
Comparisons of Y1 to previously published early Holocene records show no significant phase differences.However, sea surface temperature estimates from foraminifera and alkenone paleothermometry increased around 20-19 ka BP, as in the Western Pacific Warm Pool (WPWP). During the Last Glacial Maximum (LGM), the ECS sea level was at least 125 m lower than at present; thus, most of the present shelf was exposed (22).Sea surface temperatures in the Okinawa Trough were influenced mainly by heat transport from the tropical western Pacific Ocean by the Kuroshio Current, but the epicontinental vegetation of the ECS was influenced by atmospheric circulation linked to the northern high-latitude climate. The Okinawa Trough, close to the ECS shelf edge, has a water depth of more than 2,700 m in places and was continuously submerged during the glacial/interglacial cycles; thus, it continuously accumulated deposits of mixed terrestrial and marine sources.And many regions have shown no significant net changes or trends in either direction relative to the last few hundred to thousands of years.Your access to the NCBI website at gov has been temporarily blocked due to a possible misuse/abuse situation involving your site.
