Interglacial periods, also known as interglacials or interglacial epochs, are geological periods of relatively warm and stable climate that occur during an ice age. These periods are characterized by sea levels that are higher than during glacial periods due to the melting of large ice sheets and the subsequent rise in sea levels. Interglacials typically last for thousands to tens of thousands of years, with the most recent one being the current Holocene epoch, which began about 11,700 years ago.

The Earth's climate has undergone numerous cycles of glacial and interglacial periods over its history. These cycles are primarily driven by changes in Earth's orbit and axial tilt, which affect the distribution of solar radiation received by the planet. The most well-known theory explaining these cycles is Milankovitch cycles, which describes how variations in Earth's eccentricity, axial tilt, and precession of the equinoxes can influence the amount of solar radiation reaching different latitudes.

During interglacial periods, the global average temperature is generally higher than during glacial periods, leading to the melting of ice sheets and the rise in sea levels. This can result in significant changes to the Earth's landscape, including the formation of new coastlines and the expansion of habitable land areas. Interglacial periods have also been associated with increased biodiversity and the spread of plant and animal species.

The transition between glacial and interglacial periods is not instantaneous and can take thousands of years. During these transitions, the climate may become unstable, with rapid shifts between warm and cold conditions. This can lead to significant environmental changes, including changes in vegetation, animal populations, and sea levels.

Interglacial periods have played a crucial role in the evolution of life on Earth. The most recent interglacial period, the Holocene, has seen the development of human civilization and the spread of modern human populations across the globe. Understanding the dynamics of interglacial periods is essential for predicting future climate changes and their potential impacts on ecosystems and human societies.
