> These predictions suggest ocean temperatures of 55–85 °C during the period of 2,000 to 3,500 million years ago, followed by cooling to more mild temperatures of between 10 and 40 °C by 1,000 million years ago. Imagine going to the beach and finding the water temperature is 85C, near boiling :D. What a different world that would be.
