A new analysis indicates that the UK’s CO2 output is at a record low, and it’s largely down to one major action: a reduction in coal use.

There is no mint that can take the edge off sulfurous emissions from volcanoes, but researchers can use remote sensing to better understand volcanic breathing.

Volcanoes erupt, they spew ash, their scarred flanks sometimes run with both lava and landslides. But only occasionally. A less dramatic but important process is continuous gas emissions from volcanoes; in other words, as they exhale. A number of volcanoes around the world continuously exhale water vapor laced with heavy metals, carbon dioxide, hydrogen sulfide and sulfur dioxide, among many other gases. Of these, sulfur dioxide is the easiest to detect from space.

With their measurements and samples, nearly 3,500 schoolchildren have assisted a research study on lakes and global warming, now published in an academic journal. The results show that water temperatures generally remain low despite the air becoming warmer. This helps to curb the outflow of greenhouse gases.

Growing sustainable energy crops without increasing greenhouse gas emissions, may be possible on seasonally wet, environmentally sensitive landscapes, according to researchers who conducted a study on Conservation Reserve Program (CRP) land.

Debasish Saha, postdoctoral scholar in plant sciences, Penn State College of Agricultural Sciences, and colleagues measured the amount of nitrous oxide, a potent greenhouse gas, emanating from plots of biofuels-producing switchgrass — a native perennial grass — and miscanthus — a non-native grass species — growing in an experimental area in eastern central Pennsylvania and compared it to emissions from adjacent, undisturbed CRP acres. The experiment took place in a long-term monitoring site managed by the U.S. Department of Agriculture's Agricultural Research Service.

Babies in prams accompanying older siblings on the school run are twice as likely to be exposed to harmful air pollution in the morning than in the afternoon, a new study has found.

Iran can transition to a fully renewable electricity system and financially benefit from it by 2030. Researchers at Lappeenranta University of Technology (LUT) show that major oil-producing countries in the Middle East and North Africa (MENA) region could turn their abundant renewable energy resources into lucrative business opportunities in less than two decades.

Scientists at the Argonne National Laboratory in Illinois have created a new sponge-like material that can repeatedly soak up oil spills. The material, which can absorb up to 90 times its own weight in oil, could make it faster and easier to clean up offshore oil spills, the scientists said.

The United States has managed to reduce the amount of air pollution it produces, but you wouldn’t know it from looking at and breathing in the air. That’s because pollution created in Asia is gradually making its way across the Pacific Ocean to the western hemisphere.

According to research published in the Atmospheric Chemistry and Physics journal, up to 65 percent of the newly created smog in the U.S. has actually drifted over from Asia. The country’s western states are most vulnerable to the increase in ozone due to their proximity to the continent.

A good rain can have a cleansing effect on the land. But an MIT study published today in Nature Communications reports that, under just the right conditions, rain can also be a means of spreading bacteria.

The Environmental Protection Agency, or EPA, lists about 65 chemicals as “toxic pollutants” under the Clean Water Act, 16 of which are polycyclic aromatic hydrocarbons, or PAHs. LSU Department of Environmental Sciences doctoral candidate Parichehr Saranjampour conducted research on a chemical class of PAHs that is not on the EPA’s list — Dibenzothiophene, or DBT. DBT and its three related chemical compounds contain sulfur that is found in crude oil. Saranjampour studied how these chemical compounds move and change over time, which revealed new information that has never been published before. Her findings differ from the EPA’s information about these chemical compounds. This new research was published today in the Journal of Environmental Toxicology and Chemistry.
