I'm also very sceptical about the accuracy of data before 1990
We did sea temperature stuff in the Carribean in the 1970s early 80s and it was very hit and miss, chucking wire guided kit off the bridge wing. We did what we could but it could never ever be called high quality data
Scientists didn't even believe that rogue waves existed until the mid 1990s, as far as scientists were concerned the only wave that existed in the universe was the sine wave, sailors have known different for hundreds of years
I have no doubts that "the climate is changing" either, it's been changing for 10,000 years
