Timeline (Sol)

The Sun is getting warmer faster than expected and the Solar System needs to be evacuated. Humanity must cooperate or face imminent destruction as a civilization.

2020s

 * 2027: The temperature reaches 1.5°C above pre-industrial levels, earlier than globally expected.
 * The Climate and Energy Committee becomes the United Nation's seventh main committee. The Global Climate Cooperative is begun by the UN as well to tackle fossil fuels.

2030s

 * 2031-2035: Eastern European crisis in Ukraine, the Baltics, and the Balkan region, Russia forced to concede.
 * 2036: The Arctic Sea experiences its first ice-free summer
 * 2038: The temperature reaches 2°C above pre-industrial levels. People worldwide are affected by extreme heat and weather, decreased crop yields, supply chain issues, disease spread, and sea level rise.
 * This news helps the Democrat ticket of Jon Ossoff and Lauren Underwood win the 2038 presidential race against incumbent Republican president Josh Hawley and gain a congressional majority. Once elected, Ossoff signs key pieces of legislation into law to cut down on fossil fuels and find eco-friendly energy and infastructure solution. The United States strives to become carbon neutral by 2060.

2040s

 * 2040: the United Nations estimates that 2.3 billion people live in extreme heat (temperatures above 30°C/86°F)
 * 2050: the European Union is Carbon Neutral, as are several nations in accordance with the Paris Climate Agreement. Russia, China, and the United States are among the nations which do not meet this target. The United States and China have plans to become carbon neutral by 2060, while Russia has no clear goal.

2050s

 * Secret studies confirm that the sun is getting warmer at an alarming rate and that human contributions to climate change have not only decreased, but are less of a contributing factor to global temperatures than the sun.

2060s

 * 2060: the United Nations estimates that 3 billion people live in extreme heat (temperatures above 30°C/86°F)
 * 2062: the United States is Carbon Neutral, albeit two years later than anticipated. Plans for Carbon Zero by the end of the century or earlier are passed in congress, but with vague dates for the actual achievement of the bill's policies and policies seen as unrealistic and not enough by most experts.
 * 2069: It is publicly revealed that the sun is getting warmer at an alarming rate and that it may render life on Earth impossible within the next 120-150 years. Widespread panic ensues.

2070s

 * 2075: Following approval by almost 2/3 of the world's nations, The United Nations' authority over global affairs increases.
 * 2077: The United Nations
 * 2078: The United Nations sets up Life Evacuation Zones (commonly called "deadzones"), areas in which the average year-round temperature exceeds 40°C (104°F). These areas include large sections of land in South America, North and West Africa, the Indian Subcontinent, and Southeast Asia. People in these areas are evacuated to areas with more hospitable temperatures.
 * Many climate refugees end up in the United States, Canada, and the European Union. A new surge in right-wing populist support begins and lasts decades before dying out in the late 2080s. Notable figures include U.S. President Zachary Stavropoulos (2084-2088; Republican) and EU Regional Director for North France Adrienne Fontaine (2080-2088; Bloc Français)
