“This is why free-floating buoys are useless (for this purpose). We cannot compare the temperature records from one year to the next, because they are not measuring the same place year to year. “
LOL! First he says land stations are invalid because they are fixed and we need random locations measured.
With friends like this we don’t need enemies.
Here he says the bouys are invalid because they take random locations instead of fixed.
That’s not how a random sample works.
You cannot do a random sample of the entire Earth by letting buoys drift.
To do a random sample, you have to start from scratch and randomly sample the entire Earth, not just allow buoys to float around near where they were previously.
So free-floating buoys NEITHER work if you think sampling the same place each year works NOR do they constitute a random sample.
For example, if you are doing a random sample of voters, and you call 2929 Oak Tree Road one year, you cannot sample the house next door at 2927 Oak Tree Road next year.
That’s not a random sample
