This seems impossible to witness. Before the ocean tide floods in, the Qiantang River Tidal Bore reverses the river’s flow suddenly. A towering wall of water surges forward, rising up to 9 meters and moving at 40 kilometers per hour. Downstream, the Severn Bore races along, climbing 2 meters high and speeding at 13 kilometers per hour. The river narrows and crashes against its usual current, pulling water backward in a fierce, unstoppable pulse. The scale and force of this ocean-driven reversal reveal nature’s raw, relentless power. This is the tidal bore—where rivers run backwards.

Notes: [{"claim": "This seems impossible to witness", "explanation": "Tidal bores are natural phenomena that occur in certain rivers during specific tidal conditions and can be witnessed in several locations worldwide, such as the Qiantang River in China and the Severn River in the UK. While they may be rare and impressive, they are not impossible to witness. | Concerns: The phrase 'This seems impossible to witness' exaggerates the rarity and accessibility of tidal bores, potentially misleading viewers into thinking they are unattainable or mythical events.", "confidence": 0.9}]
