Equally the earths core and mantel being closer to it's formation, would of been hotter. So heat levels would of been offset perhaps by that aspect. Then the atmosphere would of been different. Those are two area's that I'd like to see data upon. After all, the Earth was a molten ball that slowly cools and you can't overlook that nuance over time. Which may of well balanced out the suns output levels for surface temperatures. Certainly volcanic activities and techonomic plate activities were far more active in the early days of Earth. https://en.wikipedia.org/wiki/Earth%27s_crustal_evolution https://en.wikipedia.org/wiki/Earth%27s_crustal_evolution seems a good read in conjunction with this article.

Hey, just a friendly clarification from the neighborhood grammar police - "would of" should be "would've" or "would have." No offense intended!

  Additionally, “mantel” should be “mantle” if referring to the thing underground. “Area's” should be “areas”, “suns” should be “sun's”, “techonomic” should be “tectonic”, and “may of well” should probably be “may well have”. (“may have well” might be fine.) These things don't matter all that much, though. The meaning's clear enough, apart from maybe “techonomic”.

    Techonomic activity could be earthquakes in silicon valley.

  No offence and my humble apologies. I will confess that English grammar and spelling is kryptonite for me, and maybe down to my autism and over logical mind with a language that has so many exceptions. Again, no offence and anybody who points out and explains what was wrong is always welcome and appreciated, as constructive and helpful feedback is how we learn. I will confess, the whole "would of" is one I keep doing, and something I should make more effort upon, and will. Many thanks for taking the time. FWIW I downloaded Grammarly free edition, for the best. Though any alternative suggestions are greatly appreciated.

    Grammarly is worse than useless, in my experience. Half of its suggestions turn correct grammar into incorrect grammar. (Though it does catch the obvious stuff.)

      I did catch a few changes it recommended that did not work. Though it is better than my own, obvious shortcomings. When I was at school(70's 80's), I thought such grammar and spelling correction would be easily automated away and yet. Though it may not be perfect, it is testament how hard grammar can be, translated into a rule set.

    "would of" is one many native English speakers also regularly make. Your written English seems above average to me.

  I am not sure if this can be stopped at this point. Too many people are already writing “should of”. Same for excessive apostrophe’s.

That effect is much, much smaller over periods of 100 million years than a stronger greenhouse effect. Geothermal Too small to explain the difference. See my post: https://news.ycombinator.com/item?id=30120710 https://news.ycombinator.com/item?id=30120710

Indeed, it's been theorized by many that life actually started at the deep sea hydrothermal vents. It's rich in energy, metals, etc. Even if not started there, there was a period where nearly the entire planet was under ice, and might have acted as a reservoir. On the scale of billions of years the earth spun more quickly, and the moon was significantly closer (and reflected more light on earth). Seems reasonably to expect there where more volcanoes, more hydrothermal vents, more earthquakes, and more tectonic activity of all kinds earlier in the earths history. Not to mention early in earth's history the late heavy bombardment. All making potential hospitable environments even if the earth was on average cooler than ideal. On the flip side the moon is going to keep getting further from the earth, as energy transfer via tides increases the moons velocity ... until 1 day = 1 lunar month. Thus the need for occasional leap seconds as the earth spins more slowly. Afterwards the moon will slowly decrease it's orbit because until it kits the Roche limit and turns into a ring ... unless the sun expands enough before then, which is the time scale of these changes.
