Everyone's clamouring to cut CO2 but what does the science say?

Man-made carbon dioxide emissions have been highlighted as responsible for rising global average temperatures and climate changes in the latest report by the Intergovernmental Panel on Climate Change (IPCC). The summary for policy-makers (SPM) of the first volume of the fourth assessment report predicts that the continued burning of fossil fuels at or above current rates will cause further warming. The SPM observes that 11 of the last 12 years rank among the 12 warmest years in records, that global surface temperatures have risen by 0.74 C between 1906 and 2005 and that sea levels have risen by 17 cm in the 20th century. The SPM estimates that a global average surface warming following a doubling of carbon dioxide concentrations is likely to be 2-4.5 C and is unlikely to be less than 1.5 C. The SPM predicts that sea ice will shrink in both the Arctic and Antarctic, that hot extremes and heavy precipitation will become more frequent, tropical cyclones are likely to become more intense, and that increases in the amount of precipitation are likely in high latiudes.
