Remote Work May Be Keeping Some Cities’ Air Cleaner
Widespread remote work may have kept air pollution lower than pre-COVID-19 lockdown levels even though restrictions were lifted in 2020, a new study finds.
Adapting to Receding Glaciers in the Tropical Andes
Integrated approaches are needed to understand and respond to changes in tropical mountain ecosystems and communities brought about by receding glaciers and changes in land use.
Fires Lit for Agriculture Boost Air Pollution in Southeast Asia
Reducing fires lit for agricultural management and deforestation, which unduly affect poorer populations, could help prevent 59,000 premature deaths per year.
Los beneficios para la salud y el clima de reducir la contaminación del aire
En un nuevo estudio, investigadores aplicaron un modelo global del sistema Tierra para estimar los impactos de las reducciones de emisiones por sector.
Forest Recovery in the Amazon Is a Slow Process
For the first time, a study analyzes Amazon forest loss and recovery at national and subnational levels. One finding shows that new plantings offset less than 10% of emissions associated with deforestation.
Amazon Deforestation and Fires are a Hazard to Public Health
Deforestation in the Amazon has dropped since the early 2000s, but it is slowly climbing again. A new study shows the impact of that climb on public health—and how much worse conditions could be.
How Can Wristbands Monitor Pollution, PAHs, and Prenatal Care?
Silicone wristbands can help monitor pregnant women’s exposure to polycyclic aromatic hydrocarbons. Tracking these toxic chemicals, produced by combustion, could improve public health outcomes.
Indigenous Peoples Harness Space Technology to Stop Deforestation
Satellite observations have long been used to detect deforestation, and a new study shows that giving Indigenous groups greater access to these data can improve response times and reduce tree cover loss.
