This diagram was on that link also. It mentioned a 6" rise in sea levels by 2030 for Texas and Louisiana, but talks about a 4 foot rise for Florida by 2040. I assume they are combining different "studies". Climate Change articles love to package stuff like that. IMO, it makes it more unbelievable.
https://thehill.com/blogs/congress-blog/energy-environment/259342-fifty-years-ago-the-white-house-knew-all-about-climateIt's hilarious to me that they can write an article like I linked and not notice the problems.
In 1965, they correctly predicted how much the percentage of CO
2 in the atmosphere would increase. That is one part of the science no one argues over.
The article then notes that in 1969, they extrapolate that this
could 1 lead to a 7°F rise in surface temperatures and a consequential 10' rise in ocean levels.
I'll note that those predictions did not occur, but somehow THAT part of the "THE WHITE HOUSE KNEW ALL ABOUT CLIMATE CHANGE IN 1969!!!!" didn't seem to matter.
I have as much faith in the "THE SEAS ARE GOING TO SWALLOW FLORIDA!!11!1!" as I do in the 1969 predictions because the track record of such predictions is the best means of assessing them.
1: Note that in 1969, they were aware enough to realize their predictions had a significant amount of uncertainty. Today, the predictions are just as wrong, but the uncertainty is gone.
