An international research team led by Scripps Institution of Oceanography, California, and the Centre for Australian Weather and Climate Research, suggests we should start worrying about nitrogen trifluoride (NF3) and sulfuryl fluoride (SO2F2).
Both gases are used in industrial processes, as alternatives to ozone-depleting gases, but there are concerns about their effect on global [...]

The project follows a long-running controversy over how clean hydro-electric power really is, with some estimates indicating that the methane produced from rotting organic matter, in the oxygen-poor reservoirs behind hydro dams, is greater than an equivalent power station burning the gas. Like opening a bottle of soda, a large part of the methane dissolved [...]

Atmospheric concentrations are determined by the balance of the input rate and the removal rate. Input rates have increased due to human activity removal rates are determined by the effectiveness of sinks, or systems that absorb or neutralize a GHG. The primary methane sinks are oxidation by chemical reaction with tropospheric hydroxyl, stratospheric oxidation, and [...]

The Southern Hemisphere westerly winds have moved southward in the last 30 years. A new climate model predicts that as the winds shift south, they can do a better job of transferring heat and carbon dioxide from the surface waters surrounding Antarctica into the deeper, colder waters.

The new finding surprised the scientists, said lead researcher [...]
