What is a possible explanation for why the giant ice caps that covered a supercontinent old in the Paleozoic Era melted?

The melting of the giant ice caps that covered the supercontinent during the Paleozoic Era can be attributed to significant shifts in global climate and tectonic activity. Increased volcanic activity may have released large amounts of greenhouse gases, leading to a rise in global temperatures. Additionally, changes in ocean currents and continental positions could have altered heat distribution, further contributing to the warming that caused the ice caps to melt.
