How Volcanoes Froze the Earth (Twice)

Over 600 million years ago, sheets of ice coated our planet on both land and sea. How did this happen? And most importantly for us, why did the planet eventually thaw again? The evidence for Snowball Earth is written on every continent today.

  • Man, if only those sponges had banded together to stop climate change before the glaciers melted and flooded everything. How ever could life survive with temperatures over 40F?

  • What about the earth being (almost) entirely covered in ice 2 billion years ago? Recent astronomical studies indicate that there was dust descending to the surface during millions of years about 600 or less million years ago possibly being caused by two huge "asteroids" (perhaps a L-chondrite and a comet-like object) that must have collided "near earth". That could correlate with the volcano theory of yours. In earths atmosphere, ice particels calmen the temperature while dirty dust often slowens the dissapearing of sun energy, so the warmth lasts longer

  • i would like to state that while some rocks can and do absorb CO2, most of the CO2 in the atmosphere is cleaned out by rain, and with 99% of all water on earth locked up in or below the ice, there was very little rain to clean the gases out of the atmosphere.

  • Okay I don't believe in snow earth. Yes all continents was cover in snow but not all earth. The continentals that time were all together so its possible all of them were covered in snow but not all earth first because once its covered all in snow it's really hard to unfreeze because the reflecting of the snow and even with volcanoes you need thousands of them to melt the ice or to warn the earth than you came to the problem of global warming like venus if there to much co2 or methane in the air so that's why I don't believe in snow earth

  • The answer does not reside in Volcanoes. The answer is found in Plate Tectonics of which Volcanoes are a symptom. Continental drift along with orbital mechanics coupled with precession of the axis and solar output combined in a way to cool the planet. Carbon is not the regulator unto it’s self. The cryogenian period was ended when the continents formed.

  • Maybe life flourished under the thick ice by getting energy from underwater volcanoes (which some aquatic species still do on Earth, and that theory also supports that there might be life under the ice on Jupiter's moon, Europa.

  • Scientists claim that air pollution dropped from the sky at the end of the inter-glacial period for some unknown reason, and at the other end, some scientists claim that mammoths froze as if they were falling into a cryogenic bath. so should it be possible that at the end of the inter-glacial period, for a temperature drop reason, the air liquefies until the space touches the earth for a certain time ???

  • This is the answer to global warming, we just need a calculated ice age. A lot of people will die which helps solve the overpopulation problem while simultaneously helping with the overall amount of human pollution.

    • well the co2 bounds with the rainwater over time and so turns it into a weak carbonic acid.....that carbonic acid rains down and instead of just disolving and releasing the Co2 again it it reacts with for example limestone,(what is basicly just calcium carbonate ) and so bounds the co2 in form of calcium bicarbonate. This process is called Chemical Weathering. But its a very slow process...

  • I would like to point out here that liquid water at earth's pressure levels can't really get much below 0C regardless,. So for sea life at least, conditions wouldn't have changed too much temperature wise. Arctic waters now were at basically the same temperature as sea water would have been then. And the ice that forms on the surface insulates the water below, which helps it stay liquid. Dark and low on oxygen, yes. Also slightly less water to live in, since a lot of it is ice. But other than that, not so different.
