Large amounts of ozone — around 50% more than predicted by the world’s state-of-the-art climate models — are being destroyed in the lower atmosphere over the tropical Atlantic Ocean. A team of scientists from the National Center for Atmospheric Science and the Universities of York and Leeds made the discovery, which is significant (more…)

Aging and diseased trees emit significant amounts of methane into the atmosphere, a phenomenon that may be contributing to global climate change, a new study says.

In samples collected from a forest in northeastern Connecticut, researchers at the Yale School of Forestry & Environmental Studies found that some (more…)

Peat, the accumulated turf made up of decayed vegetation, forms in many parts of the world in places like bogs, moors, and swamp forests. Due to its high carbon content, it can be harvested and burned as fuel. There are estimates that the global inventory of peat, covering 2 percent of all land area, contains 8 (more…)

The European Union says crude oil extracted from Alberta’s tar sands should be ranked as a dirtier fuel source than oil tapped from conventional oil wells, a move that could effectively ban the import of the controversial oil.

The European Commission endorsed a measure (more…)

A series of pole-to-pole research flights conducted by U.S. researchers have provided the most comprehensive picture of greenhouse gas concentrations in the atmosphere and confirmed some of climate scientists’ more dire concerns about human-caused (more…)

Measuring the emission of greenhouse gases from croplands should take into account the crops themselves. That’s the conclusion of a study in the Sept.-Oct. issue of the Journal of Environmental Quality, which examined the impact of farm practices such as tillage on the greenhouse gas, nitrous oxide. Expressing (more…)

The Intergovernmental Panel on Climate Change (IPCC) publishes its first-ever comprehensive review of low-carbon energy sources and potential, a 900-page “Bible” on renewable energy.

Word snuck out last week that the United Nations’ Intergovernmental Panel on Climate Change (IPCC) (more…)

It’s called the Greenerator (thanks to my Twitter pal SolarKnowledge for pointing out this one), and it’s the sort of renewable energy device that offers apartment dwellers a way of generating sustainable energy without the attached real estate. (more…)

Seven years after opening, North America’s only national market trading all six greenhouse gases will close its doors at the end of this year.

The Chicago Climate Exchange (CCX), a voluntary but legally binding system where (more…)

Aviation is responsible for an estimated 2 percent of global carbon dioxide emissions, and many believe they could be even more damaging because they release these pollutants high in the atmosphere.

Despite the immense challenges involved (more…)
