But as argued above, for such a time evolution it is neither a good idea to fit sea level
with a quadratic nor to fit the rate curve with a straight line — it's a bad model that gives inconsistent results.
For what it's worth,
with a quadratic fit, I get R ^ 2 = 96.5 %, p < 3.45 x 10 ^ -96.
Thus I fully agree that «for such a time evolution it is neither a good idea to fit sea level
with a quadratic nor to fit the rate curve with a straight line — it's a bad model that gives inconsistent results.»
