Sea-level rise acceleration?
climate models predict that rising CO2 levels should cause accelerated sea
level rise, sea level measurements show that, thus far, in response to roughly 3/4 century
of substantial anthropogenically-driven CO2 increases, there has been no
detectable acceleration in the rate of sea level rise. In fact, some studies have detected small
a deceleration (slowing). Here are some papers which have
reported the lack of acceleration in rate of sea level rise (h/t to Alberto
Boretti, Robert Dean & Doug Lord):

get an overestimation of the real trend." [private communication]

“What passes for science includes opinion, arguments-from-authority, dramatic press releases, and fuzzy notions of consensus generated by preselected groups. This is not science.”
Climatologist John Christy, Sept. 20, 2012
What a mess!
The Scientific Method is
what distinguishes “science” from other types of study. It is an algorithm or process
for investigating the physical world. Here's how it is supposed to work, in seven steps:
- The scientist observes the available data.
- He formulates an hypothesis to explain the observations.
- He derives testable predictions from the hypothesis.
- He devises tests or observations to test the testable predictions.
- He does the tests or makes the observations.
- If the test results match the predictions, he cries “eureka!” and
publishes. He can now properly call his hypothesis a theory or theoretical model.
He publishes it along with his data and detailed calculations, so that other
scientists can reproduce and verify his work.
- If the test results fail to match the predictions, the theory is said to be
“falsified,” so he discards or revises it and starts over at step 2,
with the new observations or test results added to the body of available data.
Step 7 is the test
of a scientist's integrity. If, instead of discarding or revising falsified
theories or models, a disappointed researcher revises the data, to make it
fit his predictions, he's no scientist worthy of the name.
“It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it disagrees with experiment, it's wrong.” - Richard Feynman (1964)
