[What is Sea Level?] (Viewer #1,942,528)
The key line in this video starts at 2:32, as they casually mention that they can only tell sea level to an accuracy of 1 meter.
Combine that with this:
“The IPCC estimates that sea levels rose 17 centimeters (or about 6.7 inches) in the 20th century. Scientists project rising sea levels to continue through the 21st century, with levels increasing between 7 and 22 inches by 2100.”
So… their predictions are within the margin of error of sea level measurement.
Something to keep in mind…
there’s also the assumption that the Earth gravitational field is static, which given tectonic movement is false.
SCIENCE!
Whoever wrote the “howstuffworks” article is a dope.
Using metric and U.S. measurements together in one sentence is something only the perpetually confused would do. And don’t get me started on the lack of units of scale on the Y axis of the graph.
I feel stupider just for having read that nonsense.
