What are the benefits of polar ice caps and glaciers on Earth?
I keep here tree huggers and leftists cry about melting polar caps and glaciers.
The only benefit of glaciers is the water that is used to make Kokanee!
DISCLAIMER: I do not buy into Man-Made-Global-Warming.
Answer:
The polar ice caps and glaciers are the main factors into what controls our planets temperatures. They reflect a huge amount of sun light back which would otherwise hit open water and heat it up far more than global warming ever will..Also, they help moderate the salinity of the ocean by adding some freshwater influence.They keep the thermohaline conveyor (and especially the North Atlantic Gulf Stream section) running which displaces heat away from the equator. 97% of the freshwater on the planet is trapped there so it could become a very important part of the planet if drinking water decreases in the far future
it has to do to do with conveyor belt of ocean water that keeps the climate, livable, so to speak. if we dont have these oceanic currents, warm water, cold water, the climate can change dramatically and in a short period of time.
having said that, i dont go for man made global warming either.
What made you become an anti - AGW proponent? You don't even know what role the polar ice caps play in the climate. What other scientific facts did you learn about before deciding that AGW is incorrect? Or is this a political issue seeing as you refer to 'leftists'? Do you just go with what your party tells you to think?
The polar ice caps reflects roughly 85 % of the Sunlight that falls upon them back in to space while water absorbs 85 % of it. Melting them would cause an increase in the amount of heat that stays on Earth.
Edit.
Troll clones ..:
There weren't any Dinosuars around during the last ice ages so how can you blame them for it?
they keep the earth cool by reflecting sunlight
you've just expressed your complete ignorance of earth climate, yet have made a determination about it whether humans have caused climate change, it amounts to a useless uninformed opinion
and what reason did you have to jump to your conclusion anyway? who are you trusting more than the scientists?
I disagree with people who say nature is good or beneficial. Nature just IS. Sometimes we find it helpful, like the gentle rain to water our crops, and sometimes we find it harmful, like tornadoes.
Nature isn't bad or good. It just IS.
We have been fighting the bad of nature (disease with medicine, drought with irrigation and so on) forever. But sometimes our efforts have unintended side effects. Like the side effects of drugs. But that is no reason to just take whatever nature throws at us. I will not give up my car and air conditioner just because of global warming. But I will try to get the most benefit for the least use of energy and I do support efforts to find new and better energy sources.
