is to "promote the general knowledge on climate change and the understanding of difficulties and obstacles, and "to make it available for a board game and still retain the major elements and processes." A quantitative-empirical study with more than 200 students shows that Keep Cool facilitates experimental learning about climate change and helps "to develop individual beliefs about sustainable development by experiencing complex system dynamics that are not tangible in everyday life." Winds of Change The European Climate Forum and Munich Re have launched a climate game called Winds of Change, which is a board game for 2-4 persons. The game illustrates the climate challenge in a playful way and it can be used in team learning, schools, focus groups, etc. It includes several features, which are hotly debated in climate policy-making. These include among others: investments in R&D, technological learning and innovation, de-carbonizing the economy, ocean uptake of , the 2 degrees limit, and insurance against extreme weather events. Climate-Poker Berlin-based Andrea Meyer, game designer with an environmental background published this card game in her company BeWitched-Spiele in 2009. Playing the card game for 2-4 persons ages 12 and up takes 30–40 minutes. The game has players collect groups of like-minded countries in order to hold conferences. The bigger the conference the better. Country cards show indicators on -emissions per capita as well as figures on consequences of extreme weather events (deaths and damages). While no knowledge is needed to play the game, players will learn a bit about who is causing climate change and who is suffering from it. On the game side, Climate-Poker requires bluffing and closely watching what the other players are aiming at. the 2 degrees limit, and insurance against. The figures in the game stem from the World Resources Institutes' Climate Analysis Indicators Tool (CAIT) and from Munich Re. CEO2 - Climate Business Game The online climate game CEO2 from World Wide Fund for Nature and Allianz is a rather complex simulation that allows one player to run a company over a period of 20 years. Players can choose from four industries (automobile, chemicals, insurance, utility). They have a limited budget and can choose from a variety of business decision like investing in smart grids or carbon capture and storage (utility). Their target is to reduce emissions significantly until 2030 without going bankrupt. Advisors (environmentalist, investors, researcher) offer help but their suggestions can be
