The Intergovernmental Panel on Climate Change (IPCC) , established by WMO and UNEP to assess scientific, technical and socio- economic information relevant for the understanding of climate change, its potential impacts and options for adaptation and mitigation, has just released hours ago their 6 year report on Climate Change 2007. This report represents a comprehensive and rigorous picture of the global present state of knowledge of climate change.
2500+ Expert reviewers, 800+ contributing authors and 450+ lead authors from 130+ countries, 6+ years work, 4 volumes, 1 Report
Some highlights of the report include:
• Global greenhouse gas (GHG) emissions have grown since pre-industrial times, with an increase of 70% between 1970-2004
• With current climate change mitigation policies and related sustainable development practices, global GHG emissions will continue to grow over the next five decades
• Both bottom-up and top-down studies indicate that there is substantial economic potential for the mitigation of GHG emissions over the coming decades, that could offset the projected growth of global emissions or reduce emissions below current levels
• In 2030 macro-economic costs for multi-gas mitigation, consistent with emissions trajectories towards stabilization between 445 and 710 ppm CO2-eq, are estimated at between 3% decrease of global GDP and a small increase, compared to the baseline
• Changes in lifestyle and behaviour patterns can contribute to climate change mitigation across all sectors. Management practices can also have a positive role
• In all analyzed world regions near-term health co-benefits from reduced air pollution as a result of actions to reduce GHG emissions can be substantial and may offset a substantial fraction of mitigation

According to FT, “The world has only eight years in which to reverse the trend of rising greenhouse gas emissions to avoid the most dangerous effects of climate change, the world’s top climate scientists warned on Friday. Taking action to reverse by the amount needed the rise in emissions of the past 150 years would cost only 0.12 per cent of annual gross domestic product, according to the most authoritative assessment yet of climate change.”
