Using low-cost air quality sensors to estimate wildfire smoke infiltration into childcare facilities in British Columbia, Canada

Abstract The health risks associated with wildfires are expected to increase due climate change. Children susceptible wildfire smoke, but little is known about indoor smoke exposure at childcare facilities. objective of this analysis was estimate the effects outdoor PM 2.5 and episodes on facilities across British Columbia, Canada. We installed low-cost air-quality sensors inside outside 45 focused our operational hours (Monday–Friday, 08:00–18:00) during 2022 season (01 August–31 October). Using random-slope random-intercept linear mixed regression, we estimated overall facility-specific , while accounting for covariates. examined how affected relationship by separately analyzing days without smoke.

Mortality Burden From Wildfire Smoke Under Climate Change

Published: April 1, 2024

Wildfire activity has increased in the US and is projected to accelerate under future climate change.However, our understanding of impacts change on wildfire smoke health remains highly uncertain.We quantify past mortality burden due fine particulate matter (PM2.5).We construct an ensemble statistical machine learning models that link variation PM2.5, empirically estimate PM2.5-mortality relationships using georeferenced data all recorded deaths from 2006 2019.We project climate-driven increases PM2.5 could result 27,800 excess per year by 2050 a high warming scenario, 76% increase relative estimated 2011-2020 averages.Cumulative exceed 700,000 between 2025-2055.When monetized, climate-induced annual damages $244 billion mid-century, comparable sum other prior analyses.Our research suggests cost be among most important costly consequences US.

In this current wildfire crisis, acknowledge widespread suffering

AMBIO, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 28, 2025

Abstract With climate change causing more extreme weather events globally, scientists have argued that societies three options: mitigation, adaptation or suffering. In recent years, devastating wildfires caused significant suffering, yet the extent of this suffering has not been defined. To encapsulate we determined impacts and effects through two systematic literature reviews. Six common themes wildfire emerged: environmental, social, physical, mental, cultural resource These varied in scale: from local to regional; individuals communities; ecosystems landscapes. We then applied these Las Maquinas (Chile) Fort McMurray (Canada) wildfires. This highlighted several strategies can reduce however our exploration indicates must address social ecological factors. analysis concludes is diverse widespread, engagement with needed if going decrease.
