Question

If increased temperatures cause the ocean to rise would decreased temperatures cause the ocean level to fall?

Answer 1

No, you've got the wrong idea. The theory is that, if global mean temperatures rise, the ice all around the world would melt, thereby increasing the global ocean water level. We are not talking about ice cubes, I'm talking millions of tons of  frozen water. Global warming is mostly just to scare us. Take a meteorology class, if your so inclined. The CO2 levels have and will go up. At the current rate, we wont have any "day after tomorrow" type stuff for hundreds of years. But we DEFINITELY need to move toward renewable fuels and energy. If we dont, we are F&CKED.crude oil is used to make hundreds of different things, including plastics actually.

Answer 2

when temperatures increase, ice glaciers and ice bergs that are scattered across cold oceans begin to melt. this is what causes sea levels to rise, and some say that within the next twenty years, places could start to flood excessively. however, when the temperature decreases, the ocean level will not start to fall, but it may start to freeze again. example:

if you leave an ice cube in any temperature above zero degrees Celsius, it will start to melt. if you put it back into temperatures below zero degrees Celsius, the amount of water doesn't fall, instead it starts to freeze.

when this happens with ice bergs and glaciers, etc, the act is known as climate change.

Answer 3

Only the percentage of permanently frozen ice and snow which sits on solid ground will affect the level of the oceans.  If that amount changes the levels of the oceans will change.  Any ice in the water already displaces an equivalent mass (slightly different volume because ice is lighter than water, that's why it floats) so if it melts or freezes it doesn't really affect ocean level.

Answer 4

If temperatures decrease enough, there is an "ice age".  The ocean's evaporate, and snow onto land.  The snow builds up into huge ice sheets and the ocean level goes down.  

Not a problem for many years to come.

In some places, (Alaska) "isostatic rebound" is causing land to *rise* because the weight of the ice on top is melting away.   Public radio specifically *denied* that this is related to global warming.
