Why???? Because as you cool water in it's liquid form, it contacts a bit and loses some volume all the way down to 32F, when it freezes and expands a bit due to crystallization. We see that everywhere where ice forms---cracking concrete, splitting rocks, etc. This is why ice floats---it is less dense than H2O in liquid form. When you melt it, the opposite occurs and you get a bit of volume contraction.
However, that is not the effect when glaciers and ice caps melt (Antarctic, not Arctic)-----that ice is over land and not part of the ocean---it adds to the ocean and causes the level to rise. And it WILL happen---it has happened over a dozen times in the last 4.5 million years of our current ICE AGE and will happen again. Coastal cities will be underwater, just as cities built on the coast 15,000-20,000 years ago are under water off the coasts of India, Japan and Mexico. And all that happened WITHOUT FOSSIL FUELS. It happened because forces much greater than your SUV are driving these cycles. What are these forces----No one knows for sure---the sun, variations in Earth's orbit, changes in the tilt of earth's axis, gravitational forces from undiscovered singularities, spacefaring aliens or God's plan----pick one or more, but your SUV is DEFINITELY NOT ON THAT LIST.
The debate now is whether human activity is changing those cycles, accelerating the global warming that has already been occurring for the last 20,000 years without any human contribution. There is data to show that warming is accelerating, but that data is 10,50, 150 years old at best and is totally inadequate to serve as a predictive model. Add to that there are those that would profit enormously by pushing this climate change agenda and the whole issue becomes less and less scientific.
The other question, even if the alarmists are right, is whether or not we can do anything about it. Frankly, we don't have the technology. The forces listed above are far more powerful than we are. Yes, we can buy EV's that only derive 80% of their energy from fossil fuels instead of 100% like an internal combustion engine, but is that going to change anything???? We might get some change if and when we develop fusion power and can have basically unlimited clean energy and can convert to hydrogen cells for vehicles, but that is at least 20+ years away, if ever. Then there are also wild cards, such as an asteroid/comet hit by one that is say 1/4 mile across--that will be the end of global warming for centuries, get your snowshoes out. Or a super volcano---just hope it isn't the one in Yellowstone.

To be absolutely fair, SOME people and 97% of scientists believe that during the recent (last 30 years) we have seen much evidence of man-made Global Warming CAUSED by our old friend - the infernal combustion engine - the kind found in Golf Cars, automobiles, snowmobiles, motorcycles and the LOUD non-catalytic converter equipped lawnmowers and lawn blowers - very LOUD that we hear every day. I BET that if they were using battery-powered lawnmowers and lawn blowers, The Villages would sound more quiet and peaceful. Yes, that would be PROGRESSIVE and fewer workers would suffer hearing damage.
The world's oceans ARE rising as proven by scientist's measurements. And the thing is, despite the occasional climate denier, we ALL know that the cause is the infernal combustion engine's excessive use in the richer 1st world countries like the US, Europe, and etc. We as a human species have been SLOW to accept these facts and last year hurricane IAN took a bite out of Florida. And humans have had many, many other warnings related to climate.
