            There was a tectonic plate movement,in witch caused masses amounts of volcanoes to erupt,putting a lot heat as well,causing the earth to heat up,in the center of our planet,causing the cold to go down to the poles & flash freeze the poles,just like in Antarctica is today,with frozen Tsunamis waves over it & all the sort in the sky,blanket the earth & cooled it down,causing the ice age & when the sort,cleared enough,to let the sun shine though,it started melting the ice back,just like what there doing now,there spraying the sky's around the world,in as many countries as they can,it cools down the center of our planet & causes the heat,to go to the poles & melt the poles,

                      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?

                                                            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
