Seriously, North Carolina? Seriously?

I am outraged about a new proposed law in North Carolina (< link to actual legal text); I feel as if this proposed law is infringing on free speech. Ok, not quite, but it is very similar. Basically it wants to limit how scientists are going to calculate sea level rises. Here's an excerpt from the bill-

The part highlighted in blue is rather disturbing to me. This proposed law wants to define how sea level rise rates can be calculated (and by whom as well).

Any data collected prior to 1900? Throw it out the window, according to this. Apparently it's not relevant. Who the heck came up with that idea? Certainly not a competent scientist. It's always in the best interest of gaining an accurate understanding of the dynamics to increase your sample size. If the data are there, why not use it?

Also notice the part about extrapolating data linearly. What if the line of best fit is exponential?

Why are lawmakers making making decisions about how to perform the scientific process? Leave the science magic to the expert scientists in the field. They know what they are doing, and the best way to do it.
