Currently, the Earth's inner core is heating up

This occurs every 12,000 years - the Earth's core and those of other planets in the Solar System (including the Sun) receive additional energy from space. It's akin to charging a smartphone battery. Excess heat is released, heating up the magma, making it more liquid and hotter. The ocean was supposed to partially dampen this process, but due to pollution with nano and microplastics, it has lost its heat conductivity. These processes are the true cause of climate change. 12,000 years ago, Atlantis was destroyed by such processes
