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.
