Climate Defense is a single-player tower defense game that tasks the player with preventing global warming by absorbing carbon dioxide (CO2) before it builds up in the atmosphere. Towers, representing set quantities of trees that could be grown to absorb carbon dioxide, can be constructed by the player to destroy CO2 clouds that march along pathways from the surface of the earth to the atmosphere in waves.
Climate change occurs when changes in Earth’s climate system result in new weather patterns that remain in place for an extended period of time. This length of time can be as short as a few decades to as long as millions of years. Scientists have identified many episodes of climate change during Earth’sgeological history.
