"For the last hundred years, the ocean has risen 20 cm — but for the previous hundred years the ocean also has risen 20 cm and for the last 300 years, the ocean has also risen 20 cm per 100 years. So there is no unusual rise in sea level. And to be sure you understand that I will repeat it. There is no unusual rise in sea level."
