A comprehensive study indicates that while the total global area affected by wildfires decreased in 2025, the economic and human costs reached record levels due to increased fire intensity in populated regions.

一項全面研究指出，雖然2025年全球受山火影響的總面積有所減少，但由於人口密集地區的火勢增加，經濟與人力成本達到紀錄高點。

The 2025 wildfire season was characterized by a divergence between the total landmass burned and the resulting systemic damage. Although the global burned area was the second lowest since 2002—attributed largely to land-use changes and agricultural expansion in Africa fragmenting savannah landscapes—insured natural hazard losses from wildfires constituted 38% of the global total. This phenomenon is attributed to the increased vulnerability of the wildland-urban interface, where population growth and climate-driven drought have heightened exposure to high-intensity blazes.

2025年山火季的特點在於總焚毀面積與由此產生的系統性損害之間出現分歧。雖然全球焚毀面積為2002年以來第二低——主因在於非洲的土地利用改變與農業擴張導致稀樹草原景觀碎片化——但山火造成的保險自然災害損失佔全球總數的38%。此現象歸因於「野地-城市界面」的脆弱性增加，人口增長與氣候驅動的乾旱提高了對高強度火災的暴露風險。

Regional data highlights severe concentrations of impact in temperate and high-latitude zones. In the United States, the Palisades and Eaton fires resulted in approximately $140 billion in total losses and 31 fatalities. South Korea experienced its most lethal wildfire season on record, with conditions deemed twice as likely due to anthropogenic climate change. In Europe, extreme heat and drought necessitated the simultaneous activation of the EU’s Civil Protection Mechanism by six nations. Notably, the United Kingdom recorded its largest burned area since records began, including the first instance of a 'megafire' exceeding 10,000 hectares on Dartmoor.

區域數據突顯溫帶與高緯度地帶的影響極其嚴重。在美國，Palisades與Eaton山火導致總損失約1,400億美元，並造成31人死亡。南韓經歷了有紀錄以來最致命的山火季，相關條件被認為是人為氣候變化導致可能性增加兩倍。在歐洲，極端高溫與乾旱迫使六個國家同時啟動歐盟的民事保護機制。值得注意的是，英國記錄到有紀錄以來最大的焚毀面積，包括在Dartmoor出現首個超過10,000公頃的「巨型山火」。

Environmental and industrial implications remain critical. North American boreal forests have released approximately four billion tonnes of CO2 since 2023, surpassing the previous 15-year aggregate and threatening the long-term carbon sequestration capacity of these biomes. In Canada, wildfires present a perennial risk to energy infrastructure; seven active blazes recently occurred within 20 kilometers of major oil sands sites in northern Alberta. Historical data indicates that such events can cause significant production curtailments, as evidenced by the 2016 Fort McMurray disaster and subsequent annual disruptions.

環境與工業影響依然嚴峻。北美北方森林自2023年起排放了約40億噸二氧化碳，超過先前15年的累計總量，威脅這些生物群落的長期碳匯能力。在加拿大，山火對能源基礎設施構成長期風險；近期在亞伯塔省北部的主要油砂場20公里範圍內發生了七場山火。歷史數據顯示，此類事件會導致顯著的減產，2016年Fort McMurray災難及隨後每年的中斷即為明證。

Furthermore, a disparity in international support has been observed. While developed nations have increased mutual aid, foreign assistance programs for wildfire mitigation in African nations were reduced in 2025. This occurs despite satellite data confirming that Africa sustains significantly higher landscape damage, with 7.3% of its landmass burned in 2024 compared to 0.6% in the US and Europe.

此外，國際支援方面觀察到差異。雖然發達國家增加了互助，但2025年針對非洲國家山火緩解的外援計畫有所減少。儘管衛星數據確認非洲的景觀損毀顯著較高，2024年有7.3%的土地被焚毀，而美國與歐洲僅為0.6%。

The current global landscape is defined by a shift toward more destructive, localized fires that threaten human life and critical infrastructure despite a reduction in overall burned acreage.

目前的全球格局定義為轉向更具破壞性、局部化的火災，儘管總焚毀面積減少，但依然威脅著人類生命與關鍵基礎設施。
