Summary: The study estimated the climate change mitigation effect under different scenarios of wood products use, finding that the mitigation effect from material substitution will decrease as the share of renewables increases, eventually disappearing by the end of the century. However, the mitigation effect of wood product use still contributes to a portion of the European emission reduction targets by 2030.

Summary: Wood use is expanding to new markets in order to replace fossil-intensive products and energy, which can contribute to climate change mitigation. However, the actual mitigation potential depends on various factors such as net fossil and biogenic emissions, market assumptions, and the realism of scenarios. This study focuses on assessing the avoided fossil emissions attributed to changes in wood use and estimating the additional mitigation potential of increased wood use in construction and textile markets. The results show that, compared to baseline, an increase in the market share of wood leads to an increase in atmospheric CO2 concentration by 2050, indicating that wood substitution impacts are not sufficient to compensate for forest carbon sinks reduction.

Summary: This study evaluates the inclusion of Short-Lived Climate Pollutants (SLCPs) and air pollutant mitigation in Nationally Determined Contributions (NDCs) submitted between 2015 and 2022. The study finds that there has been a significant increase in attention to SLCPs and air pollution in post-2020 NDCs, with more countries including explicit reduction targets for methane, black carbon, and hydrofluorocarbons. There has also been a rise in the number of specific mitigation measures included in NDCs, indicating a greater focus on reducing SLCPs and co-emitted air pollutants. These findings highlight the importance of integrating SLCP and air pollution mitigation into climate change policies.

Summary: Mesoscale eddies in the Southern Ocean play a significant role in the transport of heat, carbon, and nutrients. The intensity of the Southern Ocean eddy field has been increasing in recent decades, mainly driven by long-lived eddies. However, short-lived eddies do not show a significant trend in their amplitudes. The increased baroclinic instabilities associated with topography are responsible for the amplitude increase of long-lived eddies.

Summary: Wood-based products typically have lower fossil-based emissions over their lifecycle compared to functionally equivalent products made from other materials. However, quantifying the potential impact of large-scale material substitution at the market level remains challenging. Studies show that using wood as a substitute for other materials can reduce emissions, but the specific values are influenced by assumptions and system boundaries, limiting their generalizability.

Summary: This study provides evidence of significant delays in the timing of narwhal autumn migrations and suggests that narwhals are adopting strategic migration tactics in response to climate change. Male narwhals lead the migration out of the summering areas, while females with dependent young depart later. The time spent in summer areas is increasing at a similar rate to climate-driven sea ice loss.

Summary: Wood products are often assumed to fully substitute non-wood products in order to estimate the avoided fossil emissions. However, this study suggests that substitution rarely occurs on a one-to-one basis, and wood products can also substitute for each other. The study outlines a systematic procedure to approximate the rate of substitution between wood and non-wood products based on economic theory. The results indicate that regenerated cellulosic fibers are not perfect substitutes for synthetic fibers in textile markets, which has implications for the overall fossil emissions.

Summary: Populations of long-lived plants exhibit spatially synchronized seed production that varies extensively over time, which is known as "masting" and has significant implications for plant reproductive success, ecosystem dynamics, and plant-human interactions. While mechanistic drivers and fitness consequences of masting have been well studied, the evolutionary history, ontogenetic trajectory, and applications to plant-human interactions are still poorly understood. With increased availability of long-term datasets and advances in molecular approaches, many mysteries of masting are expected to be unraveled soon.

Summary: Many countries, including South Korea, have decided to suspend the inclusion of harvested wood products in their Nationally Determined Contributions. The accuracy of carbon accounting and conformity with policy direction are crucial when including harvested wood products in national greenhouse gases inventory. The study compared Tier 2 and Tier 3 accounting methods for carbon storage, revealing significant differences and the possibility of overestimating carbon storage using Tier 2 method in net timber-importing countries like South Korea.

Summary: Forest management plays a crucial role in greenhouse gas mitigation by representing carbon pools and enabling wood-based products to substitute fossil-intensive products. This paper analyses the theoretical GHG effects of replacing common non-wood products with wood-based products of different technology options. The study shows that the choice of substitution product is a key factor in determining the final substitution effects, and transportation has a significant impact on emissions. Informed decision-making related to the choice of substitution products is important in reducing CO2 emissions.

Summary: Forests play a crucial role in climate change mitigation by utilizing harvested wood products to extend the carbon cycle and prevent new fossil emission through substitution. A study compared different management strategies of birch spruce mixed stands over eight years and found that managed stands, through final harvest and retention, contributed more to climate change mitigation compared to unmanaged stands with prolonged rotation. The assortment structure of wood products also plays an important role in carbon balance, emphasizing the benefit of longer-lasting wood products in climate change mitigation.

Summary: We investigated the dendroclimatic response of a Pinus heldreichii metapopulation in the southern Italian Apennines, and found that wood growth along an elevational gradient is non-linearly related to air temperature. Through three years of fieldwork, we collected wood cores from 214 pine trees and used a combination of tree-ring and genetic methods to reveal factors involved in growth acclimation. Our study revealed a divergent growth response between the top and the bottom of the elevation gradient, with increased tree growth in the upper subalpine belt and a positive link between pine growth and April mean temperature at all elevations.

Summary: A mixed-integer linear programming model is developed in this paper to optimize the scheduling of harvesting activities, considering the precedence relationship among activities. The objective is to minimize the total costs by determining the start and end time of each activity at each cut block while considering machine movement time. The model is applied to a case study of a large forest company in British Columbia, Canada, with the result of a harvesting cost only 1.37% higher than the lowest possible cost and only 3 idle machines. A detailed harvesting schedule is generated based on the start and end time and operating time of each activity at each cut block.

Summary: The COVID-19 pandemic caused a significant increase in the price of softwood lumber in the United States, with over 300% change between 2020 and 2022. The higher volatility of lumber prices after the COVID-19 outbreak remains unexplained. In this paper, the authors use a calibrated random walk and an event model to study the impact of COVID-19 and other events on the price of softwood lumber, finding that the price volatility is not completely random and can be attributed to recent regional and global events. While COVID-19 did lead to a price jump, it was smaller than a rainfall event that restricted imports from Canada, and import duties and trade actions had no observable impact on U.S. lumber prices.
