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

The melting of the giant ice caps that covered a supercontinent during the Paleozoic era could be attributed to significant climatic shifts, such as increased volcanic activity releasing greenhouse gases like carbon dioxide, which raised global temperatures. Additionally, the breakup of the supercontinent could have altered ocean currents and atmospheric patterns, further contributing to warming. Changes in solar radiation and tectonic activities may have also played a role in disrupting the climate balance, leading to the melting of the ice caps.
