This paper presents a review of concepts related to wildfire risk assessment, including the determination fire ignition and propagation (fire danger), extent which may spatially overlap with valued assets (exposure), potential losses resilience those (vulnerability). is followed by brief discussion how these can be integrated connected mitigation adaptation efforts. We then operational systems in place various parts world. Finally, we propose an system being developed under FirEUrisk European project, as example different components (including danger, exposure vulnerability) generated combined into synthetic indices provide more comprehensive but also consider where on what variables reduction efforts should stressed envisage policies better adapted future regimes. Climate socio-economic changes entail that wildfires are becoming even critical environmental hazard; extreme fires observed many areas world regularly experience fire, yet activity increasing were previously rare. To mitigate negative impacts responsible for managing must leverage information available through assessment process, along improved understanding targeted improve optimize strategies risk.

Abstract Carbon capture, utilization and storage (CCUS) technologies play an essential role in achieving Net Zero Emissions targets. Considering the lack of timely reviews on recent advancements promising CCUS technologies, it is crucial to provide a prompt review advances understand current research gaps pertained its industrial application. To that end, this first summarized developmental history large-scale demonstrations. Then, based visually bibliometric analysis, carbon capture remains hotspot development. Noting materials applied process determines performance. As result, state-of-the-art emerging were comprehensively discussed. Gaps between state-of-art ideal counterpart are analyzed, insights into needs such as material design, optimization, environmental impact, technical economic assessments provided.

Human development has ushered in an era of converging crises: climate change, ecological destruction, disease, pollution, and socioeconomic inequality. This review synthesizes the breadth these interwoven emergencies underscores urgent need for comprehensive, integrated action. Propelled by imperialism, extractive capitalism, a surging population, we are speeding past Earth's material limits, destroying critical ecosystems, triggering irreversible changes biophysical systems that underpin Holocene climatic stability which fostered human civilization. The consequences actions disproportionately borne vulnerable populations, further entrenching global inequities.

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.

Abstract. Understanding and quantifying the global methane (CH4) budget is important for assessing realistic pathways to mitigate climate change. Emissions atmospheric concentrations of CH4 continue increase, maintaining as second most human-influenced greenhouse gas in terms forcing after carbon dioxide (CO2). The relative importance compared CO2 temperature change related its shorter lifetime, stronger radiative effect, acceleration growth rate over past decade, causes which are still debated. Two major challenges reducing uncertainties factors explaining well-observed arise from diverse, geographically overlapping sources uncertain magnitude temporal destruction by short-lived highly variable hydroxyl radicals (OH). To address these challenges, we have established a consortium multi-disciplinary scientists under umbrella Global Carbon Project improve, synthesise update regularly stimulate new research on cycle.

Climate change increases fire-favorable weather in forests, but fire trends are also affected by multiple other controlling factors that difficult to untangle. We use machine learning systematically group forest ecoregions into 12 global pyromes, with each showing distinct sensitivities climatic, human, and vegetation controls. This delineation revealed rapidly increasing emissions extratropical linked climate change, offset declining tropical pyromes during 2001 2023. Annual tripled one pyrome due weather, compounded increased cover productivity. contributed a 60% increase carbon from globally. Our results highlight the vulnerability of forests their stocks disturbance under change.
