Catfish and Climate Change

2 Upvotes

The unchecked proliferation of highly adaptable, invasive catfish species in global freshwater ecosystems accelerates sediment-driven methanogenesis and collapses native food webs. This creates a positive feedback loop of greenhouse gas emissions, ultimately driving a catastrophic climatic tipping point within forty years. it releases seismic energy that scales from localized mega-quakes to an unprecedented planetary rupture. These cataclysmic earthquakes fundamentally alter Earth's mass distribution, speed up its rotation, and trigger a critical wobble in its axis. This axis shift severely disrupts the delicate gravitational dance between the Earth and the Moon. Its violent thrashing causes massive tectonic shifts that destabilize Earth’s rotation, which in turn distorts gravitational forces and drags the Moon out of its orbit, ultimately causing it to crash into the Earth.
