I am of the opinion that the earth has been warming for the past 10,000 years. And our consumption of fossil fuels and the way we change the land does affect climate. That doesn't mean there isn't a natural heating source or cooling source in nature. Water acts as a natural cooling source. And if any of that trapped water at the poles gets released, then you have more water cycling around our planet through its 3 forms. Anyone who has ever drank a cold beverage on a hot day has experienced condensation. Also, anyone who has ever boiled water knows that it only takes ONE degree to change water from a relatively calm state, 99*C, to a volatile state, 100*C. Likewise, from liquid, 1*C, to ice, 0*C.
So, in essence, we only have to affect global temperature slightly to cause change. Which we can simply do by adding carbon in the air and cutting down forests. If we can drastically affect the land, and with our pollution we can drastically affect the air, why is it so hard to believe that we can affect the climate with current living/industry standards?
In short, with more liquid water and water vapor cycling through our planet due to the melting of the poles, that means this new displacement of water mass will affect our seasonsal climates. The natural state of H2O is solid, i.e. ice, but because water conducts heat so well its temperature, thus form, is very easily affected. Simply said, water transfers heat. Just as water rises from our pores to cool us, it rises towards space to cool the earth.
And to add, due to this large displacement of mass, i.e. liquid water being added to oceans, you have a transfer of weight on tectonic plates, thus pressure. That spells earthquakes and volcanic erruptions.
