Satellite imagery shows the vast extent of wildfires in Canada and the lingering veil of smoke over the Eastern U.S.

Where there’s smoke, there is fire. But with climate change, larger and longer-burning wildfires are sending smoke farther from their source, often to places that are unaccustomed to the exposure. That’s been the case this week, as smoke continues to drift south from massive wildfires in Canada, prompting warnings of hazardous air quality, and poor visibility in states across New England, the mid-Atlantic, and the Midwest.

Human-caused global warming has continued to increase at an “unprecedented rate” since the last major assessment of the climate system published two years ago, say 50 leading scientists.

Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked at 424 parts per million in May, continuing a steady climb further into territory not seen for millions of years, scientists from NOAA and Scripps Institution of Oceanographyoffsite link at the University of California San Diego announced today.

Microbes are by far the most important factor in determining how much carbon is stored in the soil, according to a new study with implications for mitigating climate change and improving soil health for agriculture and food production.

New study confirms protected forests preserve equivalent to one year of global fossil fuel emissions through avoided emissions.

The vast underground network of fungi beneath our feet stores over 13 gigatons of carbon around the world, roughly equivalent to 36 per cent of yearly global fossil fuel emissions, according to new research.

University of California, Riverside, chemical and environmental engineering scientists have identified two species of bacteria found in soil that break down a class of stubborn “forever chemicals,” giving hope for low-cost biological cleanup of industrial pollutants.

In the United States, low-income immigrant and minority children often live in environments that have highly polluted air.

Bob Powell had spent more than a decade in the energy industry when he turned his attention to the problem of plastic waste.
