Historical temperature reconstructions at high altitudes are still insufficient in southwestern China, which is considered one of the most sensitive areas to climate change in the world. Here we developed a tree ring-width chronology of Faxon fir Abies fargesii var. faxoniana at the upper timber line on Zhegu Mountain, Miyaluo Scenic Area, western Sichuan, China. The climate-tree growth relationship analysis indicated temperature as the dominant regulator on radial tree growth in this region. The reconstruction of aggregated maximum temperature (TMX) of autumn and winter for the period 1856-2016 was achieved with a linear regression model that accounted for 43.6% of the actual variability in the common time series (1954-2016). The reconstruction identified 4 warm periods and 3 cold periods. Similarities of warm and cold periods with previously published reconstructions from nearby sites indicated the reliability of our reconstruction. The significant positive correlation between TMX reconstruction and the Asian-Pacific Oscillation index and the Atlantic Multi-decadal Oscillation index suggested a linkage between large-scale climate circulations and the thermal variability at a multi-decadal scale on the western Sichuan Plateau. We also found that solar activity exerted a strong influence on decadal temperature variability in this region. The cold periods were matched well with historical large volcanic eruptions. Our results strengthen the historical climatic information in southwestern China and contribute to further understanding the regional thermal variability as well as its driving mechanism.

Makoto (まこと, lit.: truth, genuineness, reality, “realness”) is an element of the conceptual apparatus of the traditional worldview of the Japanese. In Japan, it is generally accepted that makoto is a philosophical and aesthetic concept that underlies Japanese spirituality, involving among other principles understanding of the order and laws of the truly existing Universum (shinrabansho̅; 森羅万象) and the universal interconnectedness of things (bambutsu ittai; 万物一体), the desire to understand the true essence of everything that person meets in life, and, unlike other spiritual values, is purely Shinto in origin. After getting acquainted with the Chinese hieroglyphic writing three Chinese characters were borrowed for the word makoto. Each of these characters means truthfulness, genuineness, but has its own distinctive nuances: 真 means truth, authenticity, truthfulness, 実 signifies truth, reality, essence, content, and 誠 again means truthfulness, sincerity, and truth. Makoto (“true words”) and makoto (“true deeds”) imply the highest degree of sincerity of words and honesty, correctness of thoughts, actions, and deeds. The relationship “true words — true deeds” can be seen as one of the driving factors of moral obligation, prompting everyone in their field, as well as in relations between people, to strive to be real. This desire contributed to the formation of a heightened sense of duty and responsibility among the Japanese, which became a hallmark of their character. However, makoto has not only ethical connotation, but aesthetic one as well, and can be considered as the basis on which were formed the concept of mono no aware (もののあ われ、 物の哀れ) and the aesthetic ideal of the same name, that became the first link in the chain of japanese perceptions of beauty. Each link in this chain is an expression of a new facet of makoto, which was revealed as a result of certain elements of the worldview that came to the fore in the historical era.
