Over the last 400,000 years, global temperatures have experienced significant fluctuations, primarily driven by natural cycles such as glacial and interglacial periods. During glacial periods, temperatures were markedly cooler, while interglacial periods, like the current Holocene epoch, have seen warmer temperatures. Ice core data indicate that these temperature changes correlate with variations in Earth's orbit and greenhouse gas concentrations. In recent decades, however, human activities have led to an unprecedented rise in global temperatures, surpassing natural variability.

The average global temperature has increased by approximately 1.2 degrees Celsius (2.2 degrees Fahrenheit) over the last 140 years.
