"Scientists reveal the growing atmospheric concentrations of man-made greenhouse gases are driving irreversible and dramatic changes to the way the ocean functions, with potentially dire impacts for hundreds of millions of people across the planet. "
ScienceDaily (June 29, 2010) - A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth's atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.
ScienceDaily (Jan. 6, 2011) - Australian researchers have suggested that nations should abandon the concept of carbon emissions trading in favor of a carbon swap bank that might lead to genuine reductions in the amount of carbon dioxide greenhouse gas entering the atmosphere and so provide a mechanism for reducing climate change. Details of the carbon swap bank are outlined in the journal Interdisciplinary Environmental Review.
