Record-breaking summer forest fires have become a regular occurrence in California. Observations indicate fivefold increase burned area (BA) forests northern and central California during 1996 to 2021 relative 1971 1995. While the higher temperature increased dryness been suggested be leading causes of BA, extent which BA changes are due natural variability or anthropogenic climate change remains unresolved. Here, we develop climate-driven model evolution combine it with natural-only historical simulations assess importance on BA. Our results that nearly all observed is as accounting for forcing yield 172% (range 84 310%) more than only. We detect signal combined emerging 2001 no detectable influence alone.

Abstract. Drought and heat events in Europe are becoming increasingly frequent due to human-induced climate change, impacting both human well-being ecosystem functioning. The intensity effects of these vary across the continent, making it crucial for decision-makers understand spatial variability drought impacts. Data on drought-related damage currently dispersed scientific publications, government reports, media outlets. This study consolidates data European forests from 2018 2022, using Europe-wide datasets including those related crown defoliation, insect damage, burnt forest areas, tree cover loss. data, covering 16 countries, were analysed four regions, northern, central, Alpine, southern, compared with a reference period 2010 2014. Findings reveal that all zones experienced reduced vitality elevated temperatures, varying severity. Central showed highest vulnerability, coniferous deciduous trees. southern zone, while affected by loss, demonstrated greater resilience, likely historical exposure. northern zone is experiencing emerging impacts less severely, possibly site-adapted boreal species, Alpine minimal impact, suggesting protective effect altitude. Key trends include (1) significant loss zones; (2) high levels despite 2021 being an average year, indicating lasting previous years; (3) notable challenges central Sweden bark beetle infestations; (4) no increase wildfire severity ongoing challenges. Based this assessment, we conclude (i) highly vulnerable heat, even resilient ecosystems at risk severe damage; (ii) tailored strategies essential mitigate change forests, incorporating regional differences resilience; (iii) effective management requires harmonised collection enhanced monitoring address future comprehensively.

Changes to the spatiotemporal patterns of wildfire are having profound implications for ecosystems and society globally, but we have limited understanding extent which fire regimes will reorganize in a warming world. While predicting regime shifts remains challenging because complex climate-vegetation-fire feedbacks, climate niches provides simple way identify locations most at risk change. Using globally available satellite datasets, constructed 14 metrics describing dimensions then delineated Australia's pyroregions-the geographic area encapsulating broad regime. Cluster analysis revealed 18 pyroregions, notably including (1) high-intensity, infrequent fires temperate forests, (2) high-frequency, smaller tropical savanna, (3) low-intensity, diurnal, human-engineered agricultural zones. To inform shifts, identified where under three CMIP6 scenarios is projected shift (i) beyond each pyroregion's historical niche, (ii) into space that novel Australian continent. Under middle-of-the-road projections (SSP2-4.5), an average 65% pyroregions occurred their by 2081-2100. Further, 52% pyroregion extents, on average, were occur without present-day analogues continent, implying high shifting states also lack counterparts. Pyroregions hot-arid climates both locally continentally narrower than southern already-hot lead earlier departure from space. Such implies widespread emergence no-analogue regimes.

The timely and precise detection of forest fires is critical for halting the spread wildfires minimizing ecological economic damage. However, large variation in target size complexity background UAV remote sensing images increase difficulty real-time fire detection. To address this challenge, study proposes a lightweight YOLO model (LUFFD-YOLO) based on attention mechanism multi-level feature fusion techniques: (1) GhostNetV2 was employed to enhance conventional convolution YOLOv8n decreasing number parameters model; (2) plug-and-play enhanced small-object C2f (ESDC2f) structure proposed capability small fires; (3) an innovative hierarchical feature-integrated (HFIC2f) improve model’s ability extract information from complex backgrounds fusion. LUFFD-YOLO surpasses YOLOv8n, achieving 5.1% enhancement mAP 13% reduction parameter count obtaining desirable generalization different datasets, indicating good balance between high accuracy efficiency. This work would provide significant technical support using remote-sensing images.

The impacts of accumulating atmospheric greenhouse gases on the earth's climate are now well established. As a result, there have been increases in ambient temperatures and resultant higher frequency duration temperature extremes other extreme weather events, which linked to wide range adverse health outcomes. This topical narrative review provides summary published evidence links between change stroke. There is consistent associations stroke incidence mortality increasing air pollution. Associations also shown for changes barometric pressure, wildfires, desert dust sandstorms, but current limited. Flooding events appear primarily cause service disruption, more direct may emerge.

In conclusion, increasingly community, warranting elevated attention.

Understanding the relationship between heat wave occurrence and wildfire spread represents a key priority in global change studies due to significant threats posed on natural ecosystems society. Previous have not explored spatial temporal mechanism underlying waves wildfires occurrence, especially over large geographical regions. This study seeks investigate such with focus 37 ecoregions within Eurasia longitudinal gradient. The analysis is based dataset provided by GlobFire Final Fire Event Detection meteorological ERA5-land from Copernicus Climate service. In both cases we focused 2001-2019 timeframe. By means of 12 km square grid, three metrics, i.e., density, seasonality, severity wildfires, were computed as proxy fire regime. Heat also characterized terms periods, duration, intensity for same period. Statistical tests performed evaluate different patterns area. using Geographically Weighted Regression (GWR) modeled varying relationships characteristics metrics. As expected, our results suggest that identified gradient differ regimes. However, did show differences among ecoregions, but more evident variability regime metrics outcome GWR allowed us identify locations (i.e., hotspot areas) where positive significant. Hence, hotspots presence can be seen driver forest steppe ecosystems. findings this could contribute comprehensive assessment region, thus supporting cross-regional prevention strategies disaster risk mitigation.
