Linking moisture and near-surface wind with winter temperature to reveal the Holocene climate evolution in arid Xinjiang region of China by Fuyuan Gao, Junhuai Yang, Dunsheng Xia, Hao Lu, Shuyuan Wang, Kaiming Li, Zhenqian Wang, Zhipeng Wu, Jiaxin Zhou, Fuxi Shi

“…From the early to the late Holocene, the increasing atmospheric CO2 content and winter insolation, and the shrinking of high-latitude continental ice-sheets, resulted in increasing winter temperatures in middle to high latitudes in the Northern Hemisphere. Subsequently, the increased winter temperature strengthened the winter mid-latitude Westerlies and weakened the Siberian high-pressure system, which caused an increase in winter precipitation and a decrease in near-surface wind strength. …”

Land Surface Greening and CO₂ Fertilization More than Offset the Gross Carbon Sequestration Decline Caused by Land Cover Change and the Enhanced Vapour Pressure Deficit... by Qiaoli Wu, Xinyao Wang, Shaoyuan Chen, Li Wang, Jie Jiang

“…Satellite observations have revealed strong land surface “greening” (i.e., increases in vegetation greenness or leaf area index (LAI)) in the Northern Hemisphere over the past few decades. European terrestrial ecosystems are a greening hotspot, but how they respond to land surface greening, climate change, CO₂ fertilization, land use and land cover change (LULCC) and other factors is unclear. …”

SPECIFIC FEATURES OF DEFORMATION OF THE CONTINENTAL AND OCEANIC LITHOSPHERE AS A RESULT OF THE EARTH CORE NORTHERN DRIFT by Mikhail A. Goncharov, Yuri N. Raznitsin, Yuri V. Barkin

“…Formation of such structures is caused by the upper horizontal flow of meridional convection.Meridional convection occurs due to drifting of the Earth core towards the North Pole (which is detected by a number of independent methods) and resistance of the mantle to drifting (Figures 26, and 27).By comparing the equations that describe the model of the northern drift of the lithosphere and the model of the core drift towards the North Pole, it is possible to establish a quantitative ‘bridge’ between the structures of meridional compression of the lithosphere and the core drifting structures.Conclusions based on the model of the northern drift of the lithosphere conform to many independent data and concepts, such as disturbance of the isostatic equilibrium of the Antarctica lithosphere and its high standing; the anomalously wide shelf of the Arctic ocean (Figure 28а) and the increased thickness of the sediment cover, that is rich in hydrocarbons, in combination with the ultralow velocity of spreading in Gakkel Ridge; the approximately equal areas of Antarctica and the Arctic ocean as antipodes (Figure 28б); elongation (according to GPS data) of the parallels in the Southern hemisphere, and their shortening in the Northern hemisphere (Figure 26); radial (relative to the South Pole) rifts and other lineaments in Antarctica (Figures 29, and 30); the sub-concentric (relative to the same pole) system of spreading around Antarctica, which develops northward into the submeridional system including three ‘trunks’ at a distance of about 90° (Figure 31).Due to the higher velocity of the northern drift of the lithosphere within the band with the middle meridian 100° E – 80° W, wherein the main mass of the continental lithosphere is concentrated and whose two ‘poles’ are marked by the axes of the African and Pacific superplumes (Figures 3, 4, 5, and 32), the following specific features have developed: maximum elongation of the Antarctic continent in the Southern (‘stretched’) hemisphere (Figure 28 б); maximum shortening of the Arctic ocean in the Northern (‘compressed’) hemisphere (Figure 28а); maximum spreading velocity in the SouthEastern Indian Ridge (Figure 33); maximum northern component of the horizontal displacements velocity (according to GPS data) (Figure 34); the mantle Sunda diapir of maximum width and depth (to 400 km); the Himalayas as an orogen of maximum height; Tibet as a plateau of maximum width and height; and Baikal as a rift of maximum length and depth. …”
