Summary: Wildfire activity in the western USA has increased in recent years, with larger and more extreme single-day fire spread events. The annual area burned is closely related to the number and size of these extreme events. Future warming is predicted to lead to a doubling in the number of extreme fire spread events and the area burned.

Summary: Wildfires are a threat to human society and terrestrial ecosystems, and fire danger indices such as the Canadian Fire Weather Index (FWI) are widely used to assess the risk. This study evaluates the correlation between FWI and observation-based burned area (BA), as well as the climate variables that contribute to FWI. The results show strong correlations between BA anomalies and FWI anomalies, as well as with the underlying deviations from climatology for temperature, relative humidity, precipitation, and wind. The study also highlights the importance of relative humidity and temperature as influential factors affecting BA.

Summary: This study evaluated the performance of the newly developed Cumulative Logarithmic Area Ranking Efficiency (CLARE) index in predicting burned areas under different regional and modeling conditions. The results showed that a high Area Under the receiver operating characteristic Curve (AUC) in fire occurrence models does not necessarily indicate high performance in predicting burned areas. Using a multi-variable modeling approach, particularly among models with high AUC, is likely to provide better CLARE performance than using single-variable fire index models. Additionally, this approach led to better multi-variable meteorological model performance than single-variable fire index models in regions where fire index calculation is not possible.

Summary: African and South American wildfires play a significant role in global burned areas and are closely connected to local climate. However, representing the relationship between wildfires and climate remains challenging due to their heterogeneous responses. In this study, an interpretable machine learning fire model (AttentionFire_v1.0) was developed to improve the predictability of burned areas in these regions. The model revealed a strong time-lagged control from climate wetness on burned areas and predicted a reversal in burned area trends in South America under a high-emission future climate scenario. This research provides a reliable and interpretable fire model and emphasizes the importance of lagged wildfire-climate relationships in historical and future predictions.

Summary: The research found that the total annual area burned in Northern Eurasia declined by 53% over a 15-year period, mainly due to a decrease in grassland fires. Grassland fires in Kazakhstan accounted for 47% of the total area burned and contributed to 84% of the decline, primarily driven by wetter climate conditions and increased grazing.

Summary: Recent studies have shown that wildfires in tropical regions have become more severe, with increasing burnt area. This study investigates the impact of oceanic climate modes and their teleconnection on global fire danger and trends. It reveals that temperature increases primarily drive fire trends in extratropical regions, while changes in short-term precipitation dominate trends in tropical regions. The influence of short-term precipitation is also dependent on local vegetation type and closely related to oceanic temperatures far from the burned areas.

Summary: Despite the widespread belief that global burned area and severity are increasing due to climate change, our study found a decrease in global burned area and an increase in the fraction of burned area affected by high severity. African grasslands and savannas were the most fire-prone biomes, while taiga and tundra had the highest burn severity. Although climate plays a role in the spatial patterns of burned area and severity, our study did not find climate warming to be the primary driver of current shifts in fire regimes at the global scale.

Summary: Weather and climate have a significant impact on global wildfire patterns and the distribution of burnable areas. According to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR6), fire danger is expected to increase in many regions due to warmer temperatures and drier conditions in the near future. General circulation models (GCMs) are important tools for understanding the evolution of fire danger under a changing climate. However, current fire risk scenarios have not fully considered the errors and biases in GCMs. This study evaluates the representation of fire weather indicators simulated by 16 GCMs and emphasizes the importance of GCM evaluation and selection for developing reliable projections of future climate-driven fire danger.

Summary: Siberian forests have been considered an important carbon sink, but severe droughts and fire disturbances may have affected their carbon dynamics. Limited forest inventories have led to uncertainties in the carbon balance. This study analyzed microwave observations from 2010 to 2019 and found that the carbon balance of Siberian forests was close to neutral, with a small carbon sink. Fire and drought caused significant losses of live above-ground carbon, contrasting with the greening trends in leaf area index. This highlights the vulnerability of large forest carbon stores in Siberia to climate-induced disturbances.

Summary: The frequency of heatwaves and droughts vary greatly in different climate models. Understanding the response of vegetation models to different climate conditions during these extreme events is important. Previous work has developed six different climate scenarios to study the effects of single and compound extremes on vegetation and carbon dynamics. Using these scenarios, six global vegetation models were tested, and the results showed significant variation in their responses. The findings highlight the need to improve the representation of compound events in climate models to reduce uncertainties in future carbon cycle projections.

Summary: Fire events worldwide are increasing in frequency, duration, and severity, which can potentially contaminate water bodies and affect water supply systems. The intensifying fires in Brazil's Cerrado biome, responsible for a significant portion of the country's water supply, raise ecological, climatic, and socio-economic concerns. This study proposes a remote-sensing-based Fire Impact on Water Resources Index (FIWRI) for the Brazilian territory, which analyzes fire behavior and its potential impact on inland water bodies. The index classifies fire events based on variables such as slope, river proximity, and vegetation, and could be used for real-time fire monitoring and water supply management.

Summary: Extreme weather and climate events have significant impacts on ecosystems, and their frequency or intensity is projected to increase, which could amplify ecological impacts and reduce CO2 mitigation potential. However, current risk assessments often overlook the multiple feedbacks between ecosystems and climate extremes. To address this, the authors propose a systemic framework that combines climate risk assessment and disturbance ecology to analyze the causal relationships between climate extremes, disturbance regimes, and ecosystems. This framework can help understand the role of different factors in high-impact events, incorporate uncertainties, and quantify the human influence on such events.

Summary: The year 2022 experienced record-breaking temperatures in Europe, resulting in severe summer droughts that affected 30% of the continent. Observations showed a reduction in biospheric carbon uptake in the drought-affected areas, with some regions in France even experiencing carbon release by forests. However, a warm autumn partially compensated for the decreased carbon uptake caused by the drought.

Summary: High-quality, long-time-series measurements of atmospheric greenhouse gases show variability in seasonal cycles, which can be analyzed to better understand the carbon cycle and climate drivers. Filtering and curve-fitting techniques are commonly used to analyze these measurements, but the uncertainty associated with curve fitting can lead to misinterpretation of the signal. This study uses an ensemble-based approach to quantify the uncertainty of seasonal cycle metrics and develops an alternative method to estimate the onset and termination of the carbon uptake period. The results show that the ensemble approach provides a tighter constraint and more robust results compared to traditional methods.

Summary: This study analyzed the effects of site and climate on the self-thinning line in Scots pine forests in Europe. The results showed that species tolerance, temperature, and precipitation influenced the slope of the self-thinning line. In terms of the intercept, latitude and radiation had compensating effects. Time did not show significant trends in the self-thinning line. The study highlights the need to adapt management strategies and models based on self-thinning to different latitudes. Climate change has not yet significantly impacted the self-thinning trajectory, but a continuous rise in temperature and high precipitation may accelerate the self-thinning process and result in increased biomass accumulation.

Summary: Secondary forests play a crucial role in ecosystem dynamics and biodiversity recovery. This study investigated the mechanisms underlying secondary succession in a restored secondary forest and found that deciduous tree species transition from diversity accumulators to repellents as they progress through different life history stages, while evergreen tree species can act as accumulators or remain neutral. The study also revealed the effects of density dependence on the mortality and regeneration of different tree species, and highlighted the importance of early-arriving tree species in facilitating the establishment and diversity of late-arriving counterparts.

Summary: Regeneration failures in the closed-crown boreal forest, resulting in the creation of open lichen woodlands, can be restored through clear-cutting, scarification, and natural seeding. Clear-cutting combined with scarification promotes seedling establishment, and scarification creates suitable microsites for germination. Seedling growth in lichen woodlands is higher when logging and scarification are combined, but lower compared to feather moss stands. Afforestation through natural seeding following scarification could be a cost-effective option for restoring lichen woodlands.
