It's March. It's freezing. And there's half a foot of snow on the ground. When is this winter going to end?

Many scientists think that climate change might be one cause of this year's "snowpocalypse" in Boston and bitter cold snaps in New York and Washington.

But physicists at NASA's Jet Propulsion Laboratory have been looking into another culprit: air pollution in China and India.

Ha sido necesario ocupar cinco meses del satélite más nuevo de la NASA, para monitorear el dióxido de carbono, haciendo hasta 1 millón de mediciones al día de cómo se mueve el dióxido de carbono en todo el planeta. Ahora los científicos de la NASA han compartido los primeros mapas globales creados con esos datos, que muestran una de las vistas más detalladas de CO2 jamás creados.

El satélite, conocido como OCO-2, ha estado en órbita desde julio...

The U.S. Fish and Wildlife Service today proposed to protect 338,100 acres of critical habitat in Mississippi and Alabama for black pine snakes, whose southeastern, longleaf pine forests have been reduced to less than 5 percent of their historic extent. The snake depends on these forests, which are being lost to agriculture and pine plantations, fire suppression and urbanization. Black pine snakes were proposed for Endangered Species Act protection last fall as the result of a settlement agreement with the Center for Biological Diversity that speeds protection decisions for 757 imperiled species around the country.

Restoration of wetlands can reduce greenhouse gas emissions. This is shown in a report that has been written in part by researchers from the University of Gothenburg. Former wetlands that have been drained and which are currently used for forestry and agriculture give off 11.4 million tons of carbon dioxide equivalents. That can be compared with Sweden's total emissions of 57.6 million tons (when the land use sector is not included). But in Sweden's report to the Climate Convention, emissions from drained peatland are not visible since they are included with forest growth.

If it seemed like Oregon has had a lot of unseasonably warm days this winter, well, it’s because we have. Now the focus is on a very low snowpack – and the implications that may have later this year.

The meteorological winter – which is comprised of December, January and February – recently wrapped up and depending on where you live in Oregon, it was one of the warmest – if not the warmest – winters on record.
