Sea level rising
The article quotes a rise in sea level of 5cm in 11 years. This is roughly 20 inches per century.
Since the peak (trough?) of the Ice Age 20,000 year ago, sea level has risen about 300 feet, or 18 inches per century, with almost all of that long before men were burning coal and oil. It is good to see these changes continuing at about their pre-industrial level.
