The U.S. Environmental Protection Agency is releasing the Clean Power Plan proposal today. This is the first attempt to cut carbon pollution from existing power plants, the single largest source of carbon pollution in the United States. According to the EPA, power plants account for roughly one-third of all domestic greenhouse gas emissions in the United States. While there are already standards for the level of arsenic, mercury, sulfur dioxide, nitrogen oxides, and particle pollution that power plants can emit, there are currently no national limits on carbon pollution levels.

El sector marÃtimo es una de las industrias menos reguladas en el mundo debido a las regulaciones obsoletas e internacionales que son difÃciles de aplicar a escala global. Y como los barcos entran en nuestros puertos cerca de casa, sus operaciones tienen el potencial de generar emisiones que forman smog y otros contaminantes que están vinculados a diversos problemas de salud en poblaciones susceptibles.
En un esfuerzo por combatir algunos de los contaminantes expulsados de las máquinas a diesel, la Agencia de Protección Ambiental de EE.UU. ha asignado más de un millón de dólares para ayudar a dos organizaciones especÃficas a reemplazan sus viejos motores con los modelos menos contaminantes.

Last Friday at the United Nations in New York, the Intergovernmental Oceanographic Commission of UNESCO (IOC) and the Barcelona Foundation for Ocean Sailing (FNOB) took major steps toward Ocean Conservation by presenting their joint commitment for ocean research. The announcement comes just two days before the start of the IMOCA Ocean Masters New York to Barcelona transatlantic sailing race. With members of the sailing community already acting as agents of sustainable use and protection of the world’s seas and oceans and with climate change listed as one of the key priorities of the member organizations of the United Nations for the 2015-16 agenda, this partnership represents an unprecedented alliance between the sailing and scientific communities. The partnership is part of ongoing efforts of UNESCO IOC to build a knowledge base about the oceans and coastal areas and to apply this knowledge to improve the protection and sustainable management of the marine environment and to promote sustainable communities. The formation of this partnership started at the 2011 Barcelona World Race; a two-handed, non-stop around the world race. During the race the teams pledged to collect data in the Southern Ocean, an area for which data is still lacking. The region is considered key in monitoring climate change.

A special issue of the Philosophical Transactions of the Royal Society A has been published today (Monday 2 June) which brings together a collection of papers on many of the unresolved issues relating to the Southern Ocean. Professor Michael Meredith from the British Antarctic Survey was a guest editor on the issue; 'The Southern Ocean: new insights into circulation, carbon and climate'.
The research includes: Why greenhouse gases and the ozone holes are melting the Arctic sea ice but are having a cooling effect in some parts of Antarctica, and how dust, which provides iron and essential nutrients to the ocean, might have been the cause of increased biological productivity in the southern Atlantic Ocean during the last ice age.

Climate engineering is unlikely to provide an effective or practical solution to slowing global warming, according to a new study. Reducing the release of carbon remains the only likely answer to tackling climate change ahead of fanciful projects such as positioning giant mirrors in space to reduce the amount of sunlight being trapped in the earth's atmosphere or seeding clouds to reduce the amount of light entering earth's atmosphere.
