The software developed for the exhibition, the CLIMATIZER incorporated aspects of technological, political, economic and social components of global warming. It collected data and provided a link between different knowledge systems. Scenarios were created and stored, from the most catastrophic to the most utopian. CLIMATIZER is a real-time interactive simulation of the Earth’s climate. It focuses on the negotiation of economic output and CO 2 emissions. The simulation allowed users to control all economic parameters and thereby influence CO 2 and the climate. As time passed within the simulation, the quantities of so called actors (households, industry, forest, agriculture and energy- suppliers) changed. Demands were met as intermediates (food, energy and goods) were produced, transported and consumed within the limited resources of our Earth. In the process, CO 2 was emitted and accumulated into a global average. Due to the changing CO 2 level, global average temperature continues to increase matched by an alarming sea-level rises.
