Tide Gauges Show No Sign of Carbon Driven Acceleration of Sea-Level Rise

Parker A

There are new studies claiming the sea levels have been accelerating over the 20th century where they rose faster than in any of the 27 previous centuries. This acceleration is wrongly linked to the increased carbon dioxide emission. We show how the very scattered and poor quality tide gauge information from the 19th century, and the much more extensive and better quality tide gauge information from the 20th century may suggest slower sea level rises in the 1800s than in the 1900s, but a clear change of slope at the end of the 1800s, and then constant sea level rises all over the 1900s. This change of slope has therefore nothing to do with the increasing carbon dioxide emission.
