Climate Challenge is a Flash-based global warming game produced by the BBC and developed by Red Redemption. Players manage the economy and resources of the 'European Nations' as its president, while reducing emissions of to combat climate change and managing crises. Climate Challenge is an environmental serious game, designed to give players an understanding of the science behind climate change, as well as the options available to policy makers and the difficulties in their implementation. Gameplay In Climate Challenge, the players take over the role of president in Europe. The game begins in 2000 and ends in 2100, where the time is divided into turns for every 10 years.

The president may get voted out at any time by making the incorrect choices. Resources The four resources of the game are money, power, food, and water.

These bars adjust themselves to the selected policies as they are affected. Most policy cards deplete or grow different resources, and if any of the resource bars are reduced to nothing or are entirely in the red, policy cards requiring that resource become unavailable.
