As in previous years, the Global Climate Risk Index 2012 analyses to what extent countries have been affected by the impacts of weather-related loss events (storms, floods, heat waves etc.). The most recent available data from 2010 as well as for the period 1991-2010 were taken into account. Most affected countries in 2010 were Pakistan, Guatemala, Colombia and Russia. For the period 1991 to 2010, Bangladesh, Myanmar and Honduras rank highest. This year´s analysis underlines that less developed countries are generally more affected than industrialised countries, according to the Climate Risk Index. With regard to future climate change, the Climate Risk Index can serve as a warning signal indicating pastvulnerability which may further increase in regions where extreme events will become more frequent or more severe through climate change. While some vulnerable developing countries are frequently hit by extreme events, there are also some where such disasters are a rarity. In Cancún at COP16 an Adaptation Framework was adopted in order to secure an institutional and financial support for vulnerable countries. The climate summit in Durban (COP17) will have to make substantial steps in order to further put into action the initiated processes and to scale-up adaptation.
