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.
Greenhouse gas emissions increased by a record amount last year, to the highest carbon output in history, putting hopes of holding global warming to safe levels all but out of reach, according to unpublished estimates from the International Energy Agency.
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.
