La Organización Meteorológica Mundial (OMM) ha informado que la cantidad de gases atmosféricos de efecto invernadero alcanzó un nuevo récord en 2013, impulsados por el rápido aumento de los niveles de dióxido de carbono. La noticia coincide con las tendencias en el consumo de combustibles fósiles. Pero lo que es una sorpresa es la revelación de que la tasa actual de acidificación de los océanos, que los gases de efecto invernadero (GEI) ayudan a causar, no tiene precedentes en al menos los últimos 300 millones de años.

A multinational organization that coordinates fishing activities in the western Pacific is throwing a lifeline to heavily overfished Pacific bluefin tuna stocks. Speaking today at a press briefing, Japanese officials provided details on a plan agreed to last week that aims to rebuild the spawning population by halving the catch of juveniles and limiting takes of mature fish as well. The proposal calls for total Pacific bluefin catches to be kept below the 2002 to 2004 annual average levels and for catches of fish weighing fewer than 30 kilograms—juveniles too young to spawn—to be reduced to 50% of those levels.

Although bacteria with waste-eating properties have been discovered in relatively pristine soils before, new research shows for the first time that microbes that can survive in the very harsh conditions expected in radioactive waste disposal sites have also been found. The ultimate aim of this research conducted by the University of Manchester is to improve our understanding of the safe disposal of radioactive waste underground by studying the unusual diet of these hazardous waste eating microbes.

Climate change has made us question the things that we do, from buying food and using energy to riding planes and driving cars. One of the top questions surrounding climate change is this: Which fuel type is more environmentally friendly, petrol or diesel? Common knowledge would make us reply "diesel" right away, as engines running on diesel emit less carbon dioxide or CO2, and less CO2 is better to decrease the amount of greenhouse gases in the atmosphere. However, being eco-friendly isn't as simple as emitting less CO2. Diesel-powered vehicles may emit 20% less CO2 per kilometre travelled, but they may be more harmful for local pollution due to the tiny particles that are released by diesel engines into the atmosphere. The question really isn't which fuel or engine type is more environmentally friendly, as no form of engine that uses fossil fuels will ever become good for the environment. Rather, we should look at which has the capacity to inflict the least amount of damage to the environment.

Una reciente investigación del departamento de Inspección Geológica de Estados Unidos (USGS, por sus siglas en inglés) estima que la población de morsas del Pacífico disminuyó en un 50% entre 1981 y 1999, el último año del que se dispone de datos demográficos. El estudio señala que el descenso fue más grave en la década de 1980, y luego se moderó en la década de 1990. Actualmente, el USGS está trabajando para obtener datos más recientes de la población de la morsa del Pacífico.

The freezers being tested in Central Park operate free of electricity — vendors can even charge their own mobile devices by plugging them into outlets attached to the freezer units. It seems fitting that Unilever, the world's largest producer of ice cream, is rolling out the world's first solar freezers in Central Park to keep those Popsicles, Good Humor or Magnum-brand bars cold while at the same time putting no strain on the environment.
