The relationship between carbon dioxide levels and temperature changes is fundamental to understanding climate change. Increased concentrations of CO2 in the atmosphere result from human activities, such as burning fossil fuels and deforestation, leading to the greenhouse effect. This process traps heat, resulting in rising global temperatures. Scientific research demonstrates that higher CO2 levels correlate with warming trends, which can lead to severe weather events, ice melt, and sea level rise. Addressing CO2 emissions is vital for mitigating climate change impacts.
