Evolution of Asian monsoons and phased uplift of the Himalaya–Tibetan plateau since Late Miocene times
TLDR
The results of a numerical climate-model experiment support the argument that the stages in evolution of Asian monsoons are linked to phases of Himalaya–Tibetan plateau uplift and to Northern Hemisphere glaciation.Abstract:
The climates of Asia are affected significantly by the extent and height of the Himalayan mountains and the Tibetan plateau1,2,3,4 Uplift of this region began about 50 Myr ago, and further significant increases in altitude of the Tibetan plateau are thought to have occurred about 10–8 Myr ago4,5, or more recently However, the climatic consequences of this uplift remain unclear Here we use records of aeolian sediments from China6,7 and marine sediments from the Indian8,9,10 and North Pacific oceans11 to identify three stages of evolution of Asian climates: first, enhanced aridity in the Asian interior and onset of the Indian and east Asian monsoons, about 9–8 Myr ago; next, continued intensification of the east Asian summer and winter monsoons, together with increased dust transport to the North Pacific Ocean11, about 36–26 Myr ago; and last, increased variability and possible weakening of the Indian and east Asian summer monsoons and continued strengthening of the east Asian winter monsoon since about 26 Myr ago The results of a numerical climate-model experiment, using idealized stepwise increases of mountain–plateau elevation, support the argument that the stages in evolution of Asian monsoons are linked to phases of Himalaya–Tibetan plateau uplift and to Northern Hemisphere glaciationread more

TL;DR: In this paper, the authors construct isoscapes of pedogenic carbonate δ 13 C (δ 13 c c ) over the Neogene in Asia by combining a compilation of 2236 published measurements with new data from three localities in northern Central Asia.
The deep atmospheric boundary layer and its significance to the stratosphere and troposphere exchange over the Tibetan Plateau
Xuelong Chen,Juan A. Añel,Bob Su +2 more
TL;DR: The depth of the atmospheric boundary layer (ABL) over the Tibetan Plateau was measured during a regional radiosonde observation campaign in 2008 and found to be deeper than indicated by previously measurements.

Paleoecologies and paleoclimates of late cenozoic mammals from Southwest China: Evidence from stable carbon and oxygen isotopes
TL;DR: In this article, the authors determined the carbon and oxygen isotope compositions of fossil herbivore teeth and soil samples from six localities in Yunnan Province, Southwest China, ranging in age from ∼10 to the present.

Initial Expansion of C 4 Vegetation in Australia During the Late Pliocene
Jake W. Andrae,Francesca A. McInerney,Pratigya J. Polissar,J. M. K. Sniderman,S. Howard,P. A. Hall,Samuel Phelps,Samuel Phelps +7 more
TL;DR: In this article, carbon isotope ratios of plant waxes from scientific ocean drilling sediments off north-western Australia reveal the onset of Australian C4 expansion at ~3.5 Ma, later than in many other regions.

New Precise Dating of the India‐Asia Collision in the Tibetan Himalaya at 61 Ma
TL;DR: In this paper, the India-Asia collision induced rapid uplift of the Tibetan Plateau and affected global atmospheric and oceanic circulation through the Cenozoic (Z. An et al., 2001; Ravizza & Zachos, 2014).

Global vegetation change through the Miocene/Pliocene boundary
Thure E. Cerling,John Harris,Bruce J. MacFadden,Meave G. Leakey,Jay Quade,Véra Eisenmann,James R. Ehleringer +6 more
TL;DR: For example, this paper found that between 8 and 6 million years ago, there was a global increase in the biomass of plants using C4 photosynthesis as indicated by changes in the carbon isotope ratios of fossil tooth enamel in Asia, Africa, North America and South America.

Mantle dynamics, uplift of the Tibetan Plateau, and the Indian Monsoon
TL;DR: For example, Hou et al. as mentioned in this paper show that a small increase in the mean elevation of the Tibetan Plateau of 1000 m or more in a few million years is required by abrupt tectonic and environmental changes in Asia and the Indian Ocean.

Surface Deformation and Lower Crustal Flow in Eastern Tibet
Leigh H. Royden,B. Clark Burchfiel,Robert W. King,Erchie Wang,Zhiliang Chen,Feng Shen,Y. Liu +6 more
TL;DR: This model predicts east-west extension on the high plateau without convective removal of Tibetan lithosphere and without eastward movement of the crust east of the plateau.

Correlation between climate events in the North Atlantic and China during the last glaciation
TL;DR: The authors examined grain-size data from Chinese loess and intercalated accretionary palaeosols of last-glacial age for evidence of similar climate signals remote from the North Atlantic region.

Finite strain calculations of continental deformation .2. comparison with the india-asia collision zone
TL;DR: In this article, a thin viscous sheet model for deformation of continental lithosphere subjected to an indenting boundary condition yield distributions of crustal thickness, of stress and strain rate, and of latitudinal displacements that may be compared with observations in the India-Asia collision zone.
