El Banco Mundial ha publicado un nuevo informe que destaca el hecho de que la contaminación atmosférica les cuesta a los gobiernos de todo el mundo miles de millones cada año y se encuentra entre las principales causas de muerte en todo el mundo.

Using software tools developed by Near Zero, a research group hosted by the Carnegie Institution for Science's Department of Global Ecology, a team of researchers has completed the largest expert survey yet on any energy technology, in this case wind energy.

Near Zero conducts research and assessment of energy and climate issues, focusing on integrating quantitative analysis with expert judgment. In this way, they inform decision-making to accelerate the global transition to a near-zero emission energy system. To support this work, Near Zero has developed open-source software tools to examine where experts agree and disagree and why.

A new University of Washington study, with funding and satellite data from NASA and other agencies, finds a trend toward earlier sea ice melt in the spring and later ice growth in the fall across all 19 polar bear populations, which can negatively impact the feeding and breeding capabilities of the bears. The paper, to appear Sept. 14 in The Cryosphere, is the first to quantify the sea ice changes in each polar bear subpopulation across the entire Arctic region using metrics that are specifically relevant to polar bear biology.

Los oceanógrafos del MIT y del Instituto Woods Hole Oceanographic informan que el noreste del Océano Pacífico ha absorbido una cantidad cada vez mayor de dióxido de carbono antropogénico en la última década, a un ritmo que refleja el aumento de las emisiones de dióxido de carbono inyectado en la atmósfera.

A new desert city in the United Arab Emirates without light switches or water taps has much to teach people around the world about saving energy and precious resources.

With its low-rise and energy efficient buildings, smart metering, excellent public transport - a personal transportation pod is pictured below - and extensive use of renewable energy, the 2,000 citizens of Masdar City, in Abu Dhabi, are living in a place which is a ‘green’ example to city planners around the globe.
