Few Americans may be aware of it, but in 1952 a killer fog that contained pollutants covered London for five days, causing breathing problems and killing thousands of residents.  The exact cause and nature of the fog has remained mostly unknown for decades, but an international team of scientists that includes several Texas A&M University-affiliated researchers believes that the mystery has been solved and that the same air chemistry also happens in China and other locales.

Deep stores of carbon in northern peatlands may be safe from rising temperatures, according to a team of researchers from several U.S.-based institutions.

And that is good news for now, the researchers said.

Florida State University research scientist Rachel Wilson and University of Oregon graduate student Anya Hopple are the first authors on a new study published today in Nature Communications. The study details experiments suggesting that carbon stored in peat—a highly organic material found in marsh or damp regions—may not succumb to the Earth's warming as easily as scientists thought.

Maximizing cereal crop yields in sub-Saharan Africa would still fail to meet the region’s skyrocketing grain demand by 2050, according to a new study from the University of Nebraska-Lincoln, Wageningen University and multiple African institutions.

Las temperaturas inusualmente altas y el cálido océano han llevado a una extensión récord del hielo marino en el Ártico en noviembre, según científicos del Centro Nacional de Datos de Nieve y Hielo (NSIDC) de la Universidad de Colorado Boulder. En el Hemisferio Sur, la extensión del hielo marino antártico también alcanzó un mínimo récord para el mes, causado por temperaturas moderadamente cálidas y un cambio rápido en los vientos circumpolares.

Scientists based at Oxford University have created a new method for counting lions that they say is the most robust yet devised.

Using the Maasai Mara National Reserve and surrounding conservancies in Kenya as a case study, they estimate there to be 420 lions over the age of one in this key territory. At almost 17 lions per 100 square kilometres, that represents one of the highest densities anywhere in Africa.
