Paraná's capital will be the first city in southern Brazil to trial the Google-linked network. Sensors will operate at the Pinheiros Health Unit and five other urban sites, recording air quality and weather variables in real time.
Monitoring on August 2 reported PM2.5 at 7 µg/m³ and PM10 at 21 µg/m³, with ICAP scores of 14 and 16. The daily snapshot was favorable, but local readings must be distinguished from restrictions applying in other Chilean jurisdictions.
New mapping identifies Brazilian forests that are crucial for recycling moisture toward Peru and Bolivia. The proposal targets conservation where atmospheric flows converge and where deforestation, roads and gaps in legal protection threaten the regional water cycle.
University of the Free State researchers tested a non-invasive genetic method to estimate greater kudu populations in a South African reserve. The result closely matched existing counts and can also provide data on sex, diet, parasites and the health of elusive species.
A University of Arizona-led study projects canopy temperature will rise about 0.11°C more than air temperature by the end of the century. The gap could reduce photosynthesis and transpiration, alter rainfall and accelerate warming unless models include the heat plants actually experience.
Forest fires in the Bolivian department of Tarija are spreading for the fifth consecutive day, reaching communities near the capital. Strong winds of up to 70 km/h, mountainous terrain and drought hinder firefighting efforts, while the government deploys helicopters and reinforces operations with military and firefighters.
The municipality of Zárate, in northern Buenos Aires province, is preparing for a potential historic rise in the Paraná River due to the imminent arrival of a "Super Niño." With temperature anomalies of up to 7 degrees in the Pacific, the phenomenon could surpass the events of 1997 and 2015, and resemble that of 1877-1878, with impacts on the Río de la Plata Basin between October and February.
Smoke from more than 180 active fires in northern Ontario blankets the United States, triggering air quality alerts in more than 20 states. Chicago, Detroit and Minneapolis top global pollution rankings, as authorities urge people to stay indoors and take precautions in what could be the most significant smoke event since 2023.
Tittesworth Water in Staffordshire has become the UK's largest reservoir site to achieve The Wildlife Trusts' Biodiversity Benchmark accreditation. Spanning 145 hectares of key habitats including ancient woodlands, wetlands and wildflower-rich meadows, the recognition highlights Severn Trent's nature-positive management and efforts to protect species such as the willow tit.
Marine heatwaves, episodes of abnormally high ocean temperatures, are increasingly affecting marine ecosystems globally. From die-back of key species to migration of entire populations, these extreme events pose urgent challenges for biodiversity, fisheries, and coastal communities.
At the midpoint of the UN Decade on Ecosystem Restoration, specialists set out seven recommendations for projects to better integrate scientific data, local knowledge, flexible financing and adaptive management.
A scientific commentary argues that environmental change, declining rodent diversity, reservoir microbiomes and global travel should be integrated into early warning systems under a One Health approach.
