The timeline of climate change encompasses significant events, scientific discoveries, and

international efforts related to the understanding, impacts, and response to climate change. 

1800: Industrial Revolution: The widespread use of fossil fuels, such as 

coal and later oil, begins during the Industrial Revolution.  

1896: Greenhouse Effect Theory: Swedish scientist Svante Arrhenius presents the theory that 

increasing atmospheric carbon dioxide (CO2) concentrations from 

burning fossil fuels could lead to global warming due to the greenhouse effect. 

1930: Early Climate Research: Scientists begin studying the Earth's climate system and 

the potential influence of human activities on global temperatures.
