Did the whole earth resemble Antarctica during the Ice Age, or the age of Snowball Earth? How did life survive?
Earth (planet): Was the whole world frozen during the Ice Age?
When was Ice first created by human beings? What caused the ice ages? How much would the sea level increase if all ice on the planet melted? What causes ice ages? Would the human race survive another Ice Age? How was Earth's climate before 1880? What is ice? What periods were the warmest for the Earth? What state of matter is ice? What is the science behind ice melting into water? Is an iceberg colder than an ice cube? What is the coldest country in the world? Why is it so cold? If global warming is real, why was it so cold last winter? What is the melting point of ice? What are the coldest countries in the world? Could the human race, as we are now, survive another ice age? Which were the warmest periods on Earth? What is the degree of freedom of melting ice? If you put ice in freezing water will it melt? What is the coldest country in the world? How high will sea levels actually rise if all of the polar ice capes melted? Which is the coldest place in the world? How cold would it have to be for the entire ocean to freeze? What was the Cold War? Which is the coldest country in the world? Would it be possible to dig far enough into the ice at the polar regions to sustain ourselves after an earth trauma bad enough we could not surface? By how much will sea levels rise if only the North Pole ice completely melted? If all the ice at the poles melted, how much would sea levels realistically rise? If people were cryogenically frozen alive instead of dead, would they be able to be slowly thawed out and still be alive years later? What would the universe be like if ice was denser than water?
