Water vapor is the most important greenhouse gas, responsible for about half of the Earth's natural warming effect. It accounts for 3% of atmospheric volume compared to CO2's 0.04%. However, water vapor differs from other greenhouse gases as it can turn into liquid and evaporate rapidly, with an average residence time in the atmosphere of just two weeks.
While humans emit water vapor through activities like power generation, it doesn't contribute to climate change since excess water quickly rains back into the environment. Nonetheless, rising temperatures due to CO2 emissions increase the amount of water vapor in the atmosphere, amplifying global warming via a positive feedback loop.
CO2 remains the primary cause of human-induced global warming, with water vapor being an important but indirect factor.
