The Obama administration announced new rules today that would require tighter emissions guidelines for medium and heavy-duty trucks in an effort to reduce greenhouse gases.

The rules, proposed by the Environmental Protection Agency and the Department of Transportation's National Highway Traffic Safety Administration (NHTSA), were expected to cut carbon dioxide emissions from trucks and vans by one-quarter by the year 2027.

The proposed standards affect semi-trucks, large pickup trucks and vans, buses and work trucks and cover model years 2021-2027, officials said.

Los investigadores han esbozado hoy, en una serie de informes, cómo los gobiernos, las organizaciones y las empresas se están moviendo con éxito, fuera de la explotación a corto plazo de la naturaleza, para abrazar una visión a largo plazo de la "naturaleza como un capital", el banco mundial definitivo del que dependen la salud y la prosperidad de los seres humanos y el planeta.

Los informes, publicados en las Actas de la Academia Nacional de Ciencias, sugieren que se han logrado avances significativos en los últimos diez años, y que la gente, los responsables políticos y líderes de todo el mundo están empezando a entender los servicios ambientales como algo más allá de cortar un árbol o pescar un pez.

The US has more oil spills than we thought and the number doubled after production increased six years ago. Richard Stover, PhD, and the Center for Biological Diversity counted nearly 8,000 significant incidents, between 1986 and 2014, in records of the pipeline safety administration. By “significant” they mean causing injury, death, damages exceeding $50,000 in value, a loss of 5 barrels of highly volatile substances, 50 barrels of other liquids or there was an explosion. There have been more than 500 human deaths and 2,300 injuries through-out that period. The number of plant and animal casualties is much higher.

Desde olas de calor y cultivos dañados hasta el asma en los niños, el cambio climático es un importante problema de salud pública, afirma un investigador de la Universidad Estatal de Michigan en un nuevo estudio. El cambio climático es algo más que la fusión de los casquetes polares y las imágenes de la Tierra en el fuego, dijo Sean Valles, profesor asistente en Lyman Briggs College y el Departamento de Filosofía, que cree en bioética podrían ayudar a replantear el discurso actual cambio climático.
