Por segundo año consecutivo, los niveles de dióxido de carbono en la atmósfera han aumentado a un ritmo récord, saltando 3 partes por millón (ppm) en 2016, según datos de la Administración Nacional Oceánica y Atmosférica. Las concentraciones de CO2 aumentaron 3.03 ppm en 2015, convirtiendo los dos últimos años en la primera vez que el gas de efecto invernadero aumentó más de 3 ppm en los 59 años de monitoreo de NOAA, informó la oficina Climate Central.

Change is never easy. But when it comes to adopting new agricultural practices, some farmers are easier to convince than others.

For decades, phosphorous has accumulated in Wisconsin soils. Though farmers have taken steps to reduce the quantity of the agricultural nutrient applied to and running off their fields, a new study from the University of Wisconsin–Madison reveals that a “legacy” of abundant soil phosphorus in the Yahara watershed of Southern Wisconsin has a large, direct and long-lasting impact on water quality.

Without major efforts to rebuild Louisiana’s wetlands, particularly in the westernmost part of the state, there is little chance that the coast will be able to withstand the accelerating rate of sea-level rise, a new Tulane University study concludes.

The study by researchers in Tulane’s Department of Earth and Environmental Sciences and published in the open-access journal Nature Communications shows that the rate of sea-level rise in the region over the past six to 10 years amounts to half an inch per year on average.

A new report by the USGS finds that although snow geese are increasing rapidly in northern Alaska, they are not having a negative effect on black brant. Brant are a goose species that shares its nesting habitat with snow geese.
