Ice, and water to a lesser extent, changes temps much slower (relatively speaking) than land masses.
Think about how dramatically temps change on large land masses ( American and Canadian Midwests, Siberia, Australia…. ) as fronts or air masses move thru. This same air movement has a much more “temporary “ effect over water masses, since H20 changes temp slower.
Thus, bodies of water and ice are referred to as “heat sinks” meaning that they mitigate or slow rapid temp changes. They help to maintain more consistency in our weather patterns.
As more ice disappears, not only will oceans rise, but wilder and more extreme storms will continue to increase. The loss of ice will cause even the oceans to heat and cool quicker, meaning more extremes in weather.
As some, like Trad, have mentioned, there will be winners and losers as weather patterns change. That sounds like a recipe for more migration of populations, water wars, etc…
