    Isn't this supposed to be taught at universities? Reminds of me of TOEFL exams.

      Man, scientists are dumb. Volcanos aren't cold.

        I wonder what the shape the continents will take in 250 million years. Is continental shift fast or slow? or a mix?

          Honestly to find out the truth it needs Chemistry, Biology, Astrophysics and Geology to come together. It's the only way to find out the truth. Space events could easily trigger an ice age and were believed to do so million or so years ago. Also, the equator is funny. Because it's very mixed. Sure it's warm but you also got large tropics. And the hottest place on earth is California. Which is the worst place to put a huge city. With unrestricted growth. No wonder it gets forest fires it's been stealing it's water from the land for decades. it ran the underground water dry I believe. And is stealing water from ranchers up north. transporting it to the city. Then you got Las Vegas another desert city....

          That sun idea makes sense. Because in a billion years today it will be 10% brighter. and will be able to boil our oceans. And some think that it may be able to split the molecular bonds of h20. And the Hydrogen will escape into space. Kinda interesting.

                          So can we just grind up a bunch of basalt and dump it into the ocean to sequester CO2 and undo climate change?

                                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.

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
