Rising wildfire risk to houses in the United States, especially in grasslands and shrublands

Science, Год журнала: 2023, Номер 382(6671), С. 702 - 707

Опубликована: Ноя. 9, 2023

Wildfire risks to homes are increasing, especially in the wildland-urban interface (WUI), where wildland vegetation and houses close proximity. Notably, we found that more exposed destroyed by grassland shrubland fires than forest United States. Destruction was likely fires, but they burned less WUI. The number of within wildfire perimeters has doubled since 1990s because both housing growth (47% additionally houses) area (53%). Most were WUI, which grew substantially during 2010s (2.6 million new WUI houses), albeit not as rapidly before. Any increases risk though, increase existing houses.

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.

Global expansion of wildland-urban interface (WUI) and WUI fires: insights from a multiyear worldwide unified database (WUWUI)

Environmental Research Letters, Год журнала: 2024, Номер 19(4), С. 044028 - 044028

Опубликована: Март 8, 2024

Abstract Fires in the wildland-urban interface (WUI) are an important issue globally. To understand change of WUI, we develop a 9 km worldwide unified database for 2001–2020 with Random Forest models and satellite data. We find that WUI has been increasing all populated continents from 2001 to 2020 global relative increase is 24%, largest (∼59%) over Africa. Global total fire counts decrease by 10% 2005 2020, whereas fraction increases 23%. The burned area decreases 22% 35%. These mainly due expansion area. On continents, fractions higher than area, implying fires tend have smaller sizes wildland fires. also project future changes years 2030 2040, together projection under different shared socioeconomic pathways (SSP) scenarios Community Earth System Model version 2 (CESM2). projected (excluding Antarctica oceans) 5.9% 2040 compared 4.8% 2020. now most analyzed this study, unless stays at level SSP4-4.5. This study first step understanding scale demonstrates growing importance multi-year datasets developed can facilitate work quantifying impacts on air quality climate.

Using urban pasts to speak to urban presents in the Anthropocene

Nature Cities, Год журнала: 2024, Номер 1(1), С. 30 - 41

Опубликована: Янв. 11, 2024

With more people now living in urban areas than outside of them, urbanism is becoming an increasingly important socioeconomic and ecological arena for our species the twenty-first century. Understanding historical regional variation trajectories land use has potential to provide long-term perspectives on pressing contemporary challenges. Here we review how novel methods approaches are enabling archeology shed new light past 5,500 years life. From exploring variability 'extreme' environments studying interaction Earth system, argue that provides a critical, growing reservoir knowledge scientists planners. Humanity urban, but not new, examples showcase striking variation. This Review synthesizes methodological other advances illustrate compellingly can inform current science understanding.

The Influence of Wildfire Smoke on Ambient PM_2.5 Chemical Species Concentrations in the Contiguous US

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Фев. 3, 2025

Wildfires significantly contribute to ambient air pollution, yet our understanding of how wildfire smoke influences specific chemicals and their resulting concentration in remains incomplete. We combine 15 years daily species-specific PM2.5 concentrations from 700 pollution monitors with satellite-derived PM2.5, use a panel regression estimate smoke's contribution the 27 different chemical species PM2.5. Wildfire drives detectable increases 25 out largest observed for organic carbon, elemental potassium. find that originating wildfires burned structures had higher copper, lead, zinc, nickel relative fires did not burn structures. is responsible an increasing share multiple species, some which are particularly harmful health. Using risk assessment approach, we wildfire-induced enhancement carcinogenic could cause population cancer risk, but these very small other environmental risks. demonstrate combining ground-monitored data can be used measure influence on exposures at large scales.
