Re: Sea temperature
Paleoclimate scientists can tell what the weather was like and for how long as much as 4.6 billion years ago. They have many methods from mountain strata, ice which forms layers which they can tell when and for how long which can be transferred to ocean temperatures, tree rings, layers formed in rocks. They mainly tell from ocean core samples of the oceans floor and the layers of fossils that were set in layers when and how long, known time when the tiny creatures existed and for how long, they have many methods. It is an exact science and not speculation.
