Non "scientific" observation: how come a melted glass of ice does not over flow? And conversely, why does a frozen bottle of soda expand enough to break the glass or plastic?
If you turn a liter of water to an ice cube, it will be over 10cm tall as ice as a lower density than water which is how it floats. Basically, ice occupy a fourth more space than the equivalent amount of liquid water, hence the four fifths of an iceberg are underwater.
Water is one of the few substances that expands due to it's molecules crystalizing in a way that takes up more space. Water doesn't rise when ice melts because in order for anything to float it has to displace it's own weight in water, ice does it well enough to even have 10% or so of it's mass sticking out of water.
That's also why adding salt to water doesn't raise it's level because salt dissolves and goes in between the molecules without taking up more space, at least until the water is fully saturated. (Fun fact, there are something like 19 different kinds of ice that have been discovered. You can force different crystal structures by playing around with insane pressures, and some of those types can even sink. But they don't form naturally on Earth)
The whole rising sea levels hysteria is because most of the ice locked up in the poles is actually on land. So any ice already in the ocean that melts would not rise sea levels at all, it would be ice that is on land that melts and it's run off would rise sea levels. But for the most part this is not even happening. Climate change is real, but humans only contribute a fraction of a percent to it. It is mainly from the sun, which is why we see interplanetary climate change. It's rarely mentioned that we are seeing temperatures rise on other planets as well. I don't think we have very many humans driving around on other planets.
More CO2 is good, it makes the planet more green because plants love it. It's all a giant grift. Of anything, a cooling planet would be more dangerous. If we got put into another ice age then pretty much all plant life would die.
Ah. Thank you. I learned a lot. You'd make a good teacher.
Ice on the land mass. But then we wouldn't have yearly melting snow, so do the climate geniuses factor that in? How did lake Bonneville shrivel up to an ever reducing Great Salt Lake? (Actually I know. No river flowing in.)
