The first Atmosphere Watch examines air pollution during the first eight months of 2026. Nearly 40% of the world's population was exposed to ozone levels classified as extremely high in the analysis.
At least 895,657 hectares have burned since January, while respiratory cases in affected provinces exceeded 113,000 by September 9. El Niño worsens drought, but human ignition, drained peatlands and forest degradation explain the crisis.
The agency repealed the Biden-era rule for coal and gas plants and proposed a separate mechanism to restrict future regulation. Repeal takes effect after official publication and faces legal challenges; the second measure is not final.
The 3 p.m. report on 23 August classified air quality in the Valley of Mexico as poor and the health risk as high. Iztapalapa and Nezahualcóyotl posted the worst readings, while five stations provided no data.
The 10 August emission forced flight operations to stop while the volcano was under orange alert. Colombia's Geological Service reported rising seismic energy and hotter gas and ash emissions, but ruled out a direct link to the earthquake that day.
Civil Defence keeps the alert in force through 19 August, with temperatures up to 7°C above normal and humidity below 30% across much of the state. In the western half it may fall below 20%, raising wildfire and respiratory risks.
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.
The 2024–2035 Climate Plan aims to cut net emissions 59% to 67% from 2005 levels, demarcate 4.5 million hectares of Indigenous land and expand conservation. Energy and farming projections, however, show that much of the burden will still fall on controlling deforestation.
Hood River County has received its first credits carrying the Core Carbon Principles label. The project covers more than 32,000 acres and raises the average harvest age to 90 years, but must periodically recalculate how much additional carbon storage it delivers.
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.
US power-sector emissions rose by 58 million metric tons of CO2 in 2025 as record demand from heat, data centers and industry lifted generation, while coal’s surge outweighed expanding solar and wind output.
