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.

  • You could have explained more of why sulphur dioxides helps cooling the planet. Just in case anyone is curious, it does so by forming aerosols, as sulfur dioxide forms sulphate aerosols in the stratosphere. Stratospheric aerosols reflect a lot of the Sun's light at the stratosphere, which makes impossible for that radiation to reach the troposphere and, consequently, the surface of the planet

  • Interestingly, they say human civilization has a timer on it, due to the fact that our sun will go nova in a few billion years. But given that all you need to do to radically change the planet's thermostat is move the continents around, and add volcanism, changing water currents and atmospheric composition, and solar intensity, and it's truly only a matter of time (millions of years) before we have a hot or cold planet again, either super rich in c02 or 02, and voila.

  • What if STAR WARS actually happened and Hoth was once Earth? And they just forgot about us for a few millennia because we're so far away from the Core?

  • As star wars was a long time ago in a galaxy far away, but they had hyperspeed starships... Could Earth have been Hoth?

  • Many of the assertions voiced in the video are contentious, or at least quite uncertain. For example, the position of the drop stones, which is, as she said, dependent on paleomagnetism, might not be accurate because we don't have a clear idea of what Earth's magnetic field was like back then. We lack a comprehensive theory of the magnetic field such that we can make assumptions about it that far back in time. The sulphur dioxide argument is interesting, but there have been many objections raised to it. Etc etc. I have noticed that the Snowball Earth hypothesis has indeed been getting a great deal of traction in recent years, rather suddenly too. Yet the arguments for it haven't changed much from when I first heard about it decades ago. It does neatly answer a lot of vexing questions around the geology of that time period, but I wish I could hear why the perspective on it changed so quickly, without some sort of major observational change.

  • No volcanoes -> no CO2 -> Earth becomes frozen. No rocks to absorb CO2 -> too much greenhouse effect -> Earth becomes more like Venus. We are so lucky to live on this planet! So many things had to go right for us to appear

  • Warming ocean temperatures have caused mass deaths of sponges in the Mediterranean and Caribbean over the last decade. Not so immortal to me.

  • Sea sponges can only survive in saltwater, so if you put them in freshwater, they will quickly die. They are also very sensitive to air and do not like to be taken out of the water because their pores get filled with air. If too many of their pores are filled with air, they will die.

  • How do you determine from rocks what the direction of the north pole was when they cooled? The rocks have been moved from their original orientation since then so what kind of relationship between the magnetic field lines in the rock allow you to tell something about the planet as a whole?

  • I was under The impression that volcanoes spew tons of particulate that blocks the sunlight. If you also ad in a unusual long orbit around the sun that can also make things very cold. We don't need to go back that far in time to see the destruction and weather disruption. Just read about the year without a summer.
