From Bad to Worse

WWF recently produced a summary of recent research. The main claim: “Global carbon dioxide (CO2) emissions released as a consequence of human activity have been accelerating, with their growth rate increasing from 1.1% per year between 1990 and 1999, to more than 3% per year between 2000 and 2004. The actual emissions growth rate since 2000 was greater than any of the scenarios used by the IPCC in either the Third or Fourth Assessment Reports. Over the past 15 years, about half the CO2 emissions arising from human activity have been absorbed by land and ocean. However, the capability of these natural ‘sinks’ is declining at a greater rate than forecast in earlier studies. This means that more of the CO2 emitted from human activities will stay in the atmosphere and contribute to global warming.” The full report is available at: http://assets.panda.org/downloads/wwf_science_paper_october_2008.pdf
