If governments are to make informed and transformative choices concerning climate change, they require the best and most up to date science. In 2007, the Intergovernmental Panel on Climate Change’s Fourth Assessment Report provided the world with conclusive proof that humans are altering the climate. It also outlined a range of sobering impact scenarios covering sea-level rise and extreme weather events, as well as the implications for agricultural production, human health, and the marine food chain. The IPCC’s unique, consensus-led process has been at the centre of catalyzing a political response to the phenomena unfolding across the planet as a result of fossil fuel emissions and land use changes.
Many governments and stakeholders have requested an annual snapshot of how the science has been evolving since the publication of the IPCC’s landmark fourth assessment in advance of the panel’s next one in 2014. In response to these requests, in 2009 UNEP compiled the Climate Change Science Compendium, based on the wealth of peer-reviewed research published by researchers and institutions since 2006.
The Climate Change Science Compendium 2009 is a review of some 400 major scientific contributions to our understanding of Earth Systems and climate that have been released through peer-reviewed literature or from research institutions since the close of research for consideration by the IPCC Fourth Assessment Report.
The Compendium provides important insights into the rapidly developing and fast moving realm of climate science. The findings indicate that ever more rapid environmental change is underway with the pace and the scale of climate change accelerating, along with the confidence among researchers in their forecasts.
