Amazon Surfer Sergio Laos Fights to Protect Fading Tidal Bore Waves

The Amazon's Tidal Bore: A Fading Phenomenon

• 🌊 The Poraka, or tidal bore, is a powerful wave generated by the clash of ocean and river water in the Amazon, meaning "great roar" in the Tupi language.
• 💡 This phenomenon occurs when the moon's gravitational pull pushes river water back, creating waves that can travel for dozens of miles.
• 🏄 Sergio Laos, a record-breaking surfer, is dedicated to riding these unique waves, describing them as an "Amazonian tsunami."

Threats to the Poraka

• 📉 Laos notes that the Poraka waves are significantly smaller than they were years ago, citing a reduction from around 16 ft to half that size.
• 🚜 Environmental degradation, including erosion caused by agriculture and nearby dams, has dried up rivers like the Araguari, impacting wave size.
• 🌡️ Climate change is identified as a major factor, leading to hotter temperatures and disturbed rain patterns that affect river water volume.
• 🏖️ Oceanographers observe that the sea is reaching further inland along the Mirram River, creating sandbanks and new mangroves that obstruct the ocean tide.

Hope for the Future

• 🗣️ Laos expresses hope that the upcoming climate summit in Belem (COP 30) will bring progress and renewed attention to these environmental issues.
• 🌍 He believes that addressing climate change is crucial for the future of Brazil and the world, emphasizing the need to pay attention to these impacts.
