Naturally occurring algae on Greenland’s massive ice sheet absorb large amounts of the sun’s energy and speed up the melting of the ice sheet even more than black carbon and mineral dust, according to a new study.

Las ciudades plagadas de terribles problemas de tráfico pueden estar pasando por alto una solución simple y de bajo costo: las políticas de vehículos de alta ocupación (HOV) que fomentan el uso compartido de automóviles pueden reducir el tráfico drásticamente, según un nuevo estudio en coautoría de economistas del MIT.

Short-term exposures to fine particulate air pollution and ozone—even at levels well below current national safety standards—were linked to higher risk of premature death among the elderly in the U.S. according to a new study from Harvard T.H. Chan School of Public Health.
