Climate Change

Climate change represents changes to Earth's temperature and weather patterns. It can be shown in the Intel tab.

Climate change is measured as Global Temperature Anomaly, which starts at +1.3°C. It is caused by Atmospheric Carbon Dioxide above 325.68 ppm, Atmospheric Methane above 1.3 ppm, Atmospheric Nitrous Oxide above 0.29 ppm and Excess Stratospheric Aerosols above 0ppm.

Climate change can be worsened by things such as the Spoils and Economy priorities. It can be improved by using the Welfare priority. Certain regions are affected more or less by climate change. Every use of a Strategic Nuclear Barrage increases Excess Stratospheric Aerosols by 0.00777 ppm.

Effects
Climate change lowers annual GDP in every nation. In addition, as long as Global Temperature Anomaly is above or below a certain value it will cause regular negative events.

Global Sea Level Anomaly
Global Sea Level Anomaly starts at +24cm. There are 10 glaciers, basins and shelves that may melt if climate change is not stopped, most of them increasing Global Sea Level Anomaly. Once Global Sea Level Anomaly rises above +60cm it will become visible and start causing negative effects.
