“…At middle and lower elevations, there may be a tendency for an increase in the effect of moisture stress. In this case, the radial growth of trees is likely to increase at upper elevations (2000-2300 m) and decrease at middle and lower elevations (1000-1500 m) (Zhang et al, 2023). Dendroclimatological analyses showed that late winter-early spring and summer temperatures and May precipitation positively affected growth.…”

Changes in climatic conditions have ecological and economic consequences or impact for trees and forest stands. In this respect, it is crucial to understand the radial growth trends of trees, their ecological response across elevation gradients, and the possible impacts of climate change on the species. In this study, Picea orientalis (L.) Peterm, located in the Fırtına Creek Basin in the northern part of the Eastern Black Sea Mountains in northeastern Turkey, was investigated along different elevation gradients in the context of climate-growth response. In the study, six site chronologies along an elevation gradient from 900 m to 2050 m were developed. Dendroclimatological methods were applied to assess the elevation-dependent radial growth characteristics of trees. In total, 200 increment cores were collected from 98 living trees. The relationships between climate and tree ring growth along the elevation gradient showed a positive relationship between growth and temperature at upper elevations (1700–1900 m) and a positive relationship between growth and precipitation at middle elevations (1400–1600 m). In particular, January–April mean temperatures and May rainfall were positively correlated with tree-ring growth. At lower elevations (900–1100 m), the correlation coefficients between climate and growth are insignificant because, at these altitudes, the species have optimum ecological conditions. It was also found that mean temperatures between 0 °C and 2 °C in January–April and total precipitation between 60 and 100 mm in January–February positively affect tree growth. However, if these thresholds are exceeded, it is possible that growth may be adversely affected. This research underscores the complex interplay between climate variables and tree growth along elevation gradients, highlighting the need for adaptive management strategies in the face of changing climatic conditions.

“…Major changes in temperature and precipitation patterns occur under global warming [2]. The study area is located at a high latitude and high altitude and its forest ecosystems are highly sensitive to climate change [24,44,45]. During the past 70 years, dramatic climate change in the study area has led to a shift in the correlation between tree growth and climate, with winter precipitation (snowfall) becoming the main limiting factor for Dahurian larch growth.…”

Against the background of global warming, trees in high-latitude and high-altitude areas are more sensitive to rapid warming. Revealing the response patterns of trees at different altitudes to rapid warming in typical alpine mountain environments can help to predict the future distribution of forests in the region and the associated changes in the timberline. This study used tree-ring width data (band sampling) from Dahurian larch (Larix gmelinii Rupr.) along an altitudinal gradient (970–1409 m) on Oakley Mountain to establish 10 chronologies and to analyze the growth–climate response of larch to warming and altitudinal changes along a gradient. The results showed that before rapid warming, larch growth was strongly influenced mainly by precipitation in July–August, while after warming, the growth was controlled mainly by precipitation (snowfall) in winter (October–April) and showed a significant positive correlation with the SPEI in winter and a negative correlation with temperature in February–April (early spring). This indicates that the rapid warming event led to a drastic change in the water heat balance during the pre-growth period of the trees in the study area, which shifted the tree growth from being restricted by drought in the growing season before warming to being restricted by winter drought (i.e., the lagged effect of snowfall in the pre-growing season) after warming and that the trees at low altitudes suffered from more severe winter drought. In the future, as the global climate warms further, the growth of mountain larch at low altitudes (below 1200 m) will continue to decrease, and the coupling of winter snowfall and seasonal (February–April) warming will increase the upper altitude limit at which winter drought occurs for larch in the study area; additionally, larch at higher altitudes will be able to cope with this ecological process better.

“…It is due to the continuous accumulation of the greenhouse effect, resulting in the imbalance of energy absorbed and emitted by the ground-air system, and the continuous accumulation of energy in the ground-air system, resulting in temperature rise and global climate warmin [5] . Therefore, with the intensification of global warming, the distribution of global temperature in the future has become an important focus issue [9] .…”

The life of most industrial instruments is closely related to the local climate, and there is a significant correlation between the development of industry and the local climate. In order to explore the future global temperature distribution pattern and temperature level under the global warming trend, the global temperature data published in Worldclim is used. The XGBoost-RedRNN++ model is proposed in this paper to forecast the future temperature, and the regional global temperature prediction is carried out with 5 'as the precision unit. After predicting global average temperature of 20.78 centigrade in 2050 and 22.54 centigrade in 2100. The similarity of the global average temperature distribution in 2050 and the average temperature distribution in 2021 is 95.54%, and the similarity of the global average temperature distribution in 2100 compared with 2021 is 81.21%. With time going on, the temperature is generally rising everywhere. The global lowest temperature in 2050 and 2100 will be in Antarctica, with an average annual temperature of -14.6 centigrade and -12.4 centigrade. The highest global temperature in 2050 and 2100 will occur in Central Africa, with an average annual temperature of 85.2 centigrade and 87.5 centigrade. Additionally, it was observed that the temperature gradually decreased from the equator to the poles, and the land temperature in the southern hemisphere was significantly higher than that in the northern hemisphere. This study can not only lay the foundation for the future industrial development, but also provide theoretical support for the reform direction of the national industrial constitution.
