What is a possible explanation for way the giant ice caps that covered a super continent in the Paleozoic era melted?

The giant ice caps that covered the supercontinent Gondwana during the Paleozoic era likely melted due to a combination of geological and climatic changes. As tectonic plates shifted, volcanic activity increased, releasing greenhouse gases like carbon dioxide into the atmosphere, which raised global temperatures. Additionally, changes in ocean currents and patterns of rainfall may have also contributed to a warmer climate, further accelerating the melting of ice caps. This shift played a significant role in the transition from the glacial period to a more temperate climate.
