Climate change is about changing temperatures. Not necessarily about changing water-lines.

We've got over 150 years of solid temperature measurements. We can reach into historical measurements of varying accuracy as well (such as that Japanese ritual where they measured an ice bridge for the past 600 years for religious reasons).

The average temperature of the world has rose by approximately 1.5 degrees Celsius since the 1850s. Do you agree or disagree with this fact?
