New Paper from Bob Kopp, Ben Horton ‘Temperature-Driven Global Sea-Level Variability in the Common Era’ Picked Up Nationally


The paper, Temperature-driven global sea-level variability in the Common Era goes into detail on how in the past century, sea level has risen more rapidly than it had in nearly 3,000 years.

Kopp outlines in his blog the four main take aways of the article as:

  • global sea-level change in the 20th century was the fastest its been since 800 BCE
  • 20th centruy wasn’t the only period where change in global temperature and sea-level coincided
  • using a ‘semi-empirical’ statistical model calibrated to the relationship between temperature and global sea-level change over the last 2000 years, in alternative histories where the 20th century did not exceed the average temperature over 500-1800 CE, global sea-level rise in the 20th century would have been less than half of its observed value
  • the findings coincide with the projections from the 2014 Earth’s Future paper adding confidence to the projection
