During intense El Niño events, which outcome relating to river sediment occurs?

💡 Explanation

El Niños increase precipitation and therefore river discharge, leading to greater sediment transport; the Abrupt Climate Change theory links this process to Catastrophic Megafloods depositing extra river sediment as increased coastal loess because increased erosion supplies the material, rather than decreasing oxbows.

• Which outcome increases following severe storm surge overtopping engineered coastal barriers?
• Which environmental impact intensifies when deflation removes loess deposits?
• Which risk sharply increases along Arctic pipeline routes when ambient temperatures rise above freezing?
• Which outcome results when thermohaline circulation weakens near the Greenland ice sheet melt?
• Which mechanism causes differential erosion rates along the walls of a fjord during glacial retreat?
• Which surface outcome results when wind exceeds threshold?
