Abstract. Climate change contributes to the increased frequency and intensity of wildfires globally, with significant impacts on society environment. However, our understanding global distribution extreme fires remains skewed, primarily influenced by media coverage regionalised research efforts. This inaugural State Wildfires report systematically analyses fire activity worldwide, identifying events from March 2023–February 2024 season. We assess causes, predictability, attribution these climate land use forecast future risks under different scenarios. During 2023–2024 season, 3.9×106 km2 burned slightly below average previous seasons, but carbon (C) emissions were 16 % above average, totalling 2.4 Pg C. Global C record in Canadian boreal forests (over 9 times average) reduced low African savannahs. Notable included record-breaking extent Canada, largest recorded wildfire European Union (Greece), drought-driven western Amazonia northern parts South America, deadly Hawaii (100 deaths) Chile (131 deaths). Over 232 000 people evacuated Canada alone, highlighting severity human impact. Our revealed that multiple drivers needed cause areas activity. In Greece, a combination high weather an abundance dry fuels probability fires, whereas area anomalies weaker regions lower fuel loads higher direct suppression, particularly Canada.

With large wildfires becoming more frequent1,2, we must rapidly learn how megafires impact biodiversity to prioritize mitigation and improve policy. A key challenge is discover interactions among fire-regime components, drought land tenure shape wildfire impacts. The globally unprecedented3,4 2019–2020 Australian burnt than 10 million hectares5, prompting major investment in monitoring. Collated data include responses of 2,000 taxa, providing an unparalleled opportunity quantify affect biodiversity. We reveal that the largest effects on plants animals were areas with frequent or recent past fires within extensively areas. Areas at high severity, outside protected under extreme also had larger effects. included declines increases after fire, rainforests by mammals. Our results implicate species interactions, dispersal extent situ survival as mechanisms underlying fire responses. Building resilience into these ecosystems depends reducing recurrence, including rapid suppression frequently burnt. Defending wet ecosystems, expanding considering localized could contribute. While countermeasures can help mitigate impacts megafires, reversing anthropogenic climate change remains urgent broad-scale solution. Data collected from taxa provide biodiversity, revealing

Abstract Altered fire regimes are a global challenge, increasingly exacerbated by climate change, which modifies weather and prolongs seasons. These changing conditions heighten the vulnerability of ecosystems human populations to impacts wildfires on environment, society, economy. The rapid pace these changes exposes significant gaps in knowledge, tools, technology, governance structures needed adopt informed, holistic approaches management that address both current future challenges. Integrated Fire Management is an approach combines prevention, response, recovery while integrating ecological, socio-economic, cultural factors into strategies. However, remains highly context-dependent, encompassing wide array practices with varying degrees ecological societal integration. This review explores as adaptation mitigation strategy for altered regimes. It provides overview progress challenges associated implementing across different regions worldwide. also proposes five core objectives outlines roadmap incremental steps advancing adapt ongoing regimes, thereby maximizing its potential benefit people nature.

Climate change is considered to affect wildfire spread both by increasing fuel dryness and altering vegetation mass structure. However, the direct effect of global warming on wildfires hard quantify due multiple non-climatic factors involved in their ignition spread. By combining observations with latest generation climate models, here we show that more than half large (area>500 ha) occurring Iberian Peninsula between 2001 2021 present a significant increase rate respect what it would have been pre-industrial period, attributable warming. The average acceleration increased 2.0% 8.3%, whereas influence enhanced growth since period could potentially be even higher impact temperature conditions.

Background Climate change is expected to significantly wildfire frequency and magnitude, which poses particular challenges for countries with limited experience in managing wildfires, such as Austria. Aims To develop a vulnerability index, this study aims at weighting the characteristics of buildings their surroundings (vulnerability indicators) by involving different national stakeholders (Austria) international experts. Methods Expert judgement analytic hierarchy process (AHP) were used indicators identified previous through literature review. Key results The two expert groups regarding compared. A index that combines all into single assigned each building introduced. Conclusions tool decision-makers other end users sets foundations ongoing research field assessment based on trans-disciplinary approaches both academia stakeholders. Implications can be support decision-making, risk reduction climate adaptation strategies but it also guide local level.

Climate-driven increases in wildfire frequency may disrupt soil carbon dynamics, potentially creating positive feedback within global cycle. However, the release and lability of following remain unclear, limiting our ability to predict fire impacts on cycling. Here, we investigated chemical alterations water-extractable organic matter (WEOM) a subtropical forest by comparing burned soils an adjacent unburned site. The consensus is that fire-altered DOM aromatic less reactive. found 10 months postfire, contained nearly three times more (WEOC) than control Reactomics analysis further revealed overall 8-fold increase potential reactivity this carbon, identified higher abundances molecular formulas involved microbial reaction pathways. Specifically, exhibited elevated oxidative enzyme reactions, linked nominal oxidation state (NOSC) WEOM. Metagenomic enrichment taxa specialized degrading compounds areas, supporting occurrence pathways acting WEOM postfire soils. These findings highlight wildfires accelerate loss through reactive mobilization response, with implications for long-term carbon-climate projections.
