Study Reveals Mount Etna’s Extraordinary CO2 Emissions Were Activated by Carbon Dioxide in the Earth’s Mantle

The transport of carbon dioxide (CO2) stored at a depth of roughly 50 to 150 km in the Earth’s lithospheric mantle underneath the Hyblean Plateau in southern Italy is accountable for the extremely large CO2 emission of Mount Etna.

Copper Released into the Environment may be Contributing to Stratospheric Ozone Depletion

Copper released into the environment from fungicides, brake pads, antifouling paints on boats and other sources may be contributing significantly to stratospheric ozone depletion, according to a new study from the University of California, Berkeley.

Scientists Investigate Peat Mosses' Responses to the Increase in Atmospheric CO2

Scientists at Umeå University, Sweden, and Swedish University of Agricultural Sciences have developed ways to decipher effects of the CO2 rise during the past 100 years on metabolic fluxes of the key plant species in peatlands, mosses.

Controlling Methane Emissions with Inexpensive Clay Material

Methane is a far more potent greenhouse gas than carbon dioxide, and it has a pronounced effect within first two decades of its presence in the atmosphere. In the recent international climate negotiations in Glasgow, abatement of methane emissions was identified as a major priority in attempts to curb global climate change quickly.

Refining the Understanding of Ozone Smog and Its Interactions with Climate

Climate change and air pollution are interlocking crises that threaten human health. Reducing emissions of some air pollutants can help achieve climate goals, and some climate mitigation efforts can in turn improve air quality.

Study: More than 68% of the Western U.S. Affected in One Day by Air Pollution from Wildfires

Large wildfires and severe heat events are happening more often at the same time, worsening air pollution across the western United States, a study led by Washington State University researchers has found. In 2020, more than 68% of the western U.S. – representing about 43 million people – were affected in one day by the resulting harmful-levels of air pollution, the highest number in 20 years.
