The sea level would rise dramatically and flood coastal areas, putting them underwater. A lot of Arctic animals would die - penguins, polar bears, seals, etc. would drown. The water's temperature would change, causing coral reefs all over the world to bleach out and die. Most marine life would suffer from the loss of their environments, and larger animals on the food chain would wipe out from the dwindling numbers of their prey.
No. Uranus does not have a solid surface for the caps to be on. Earth and Mars have polar ice caps.
Mars, Earth, and Pluto have polar ice caps. Mars' polar ice caps are primarily made of water and carbon dioxide ice, Earth's polar ice caps are primarily made of frozen water, and Pluto's polar ice caps are a mixture of methane and nitrogen ice.
Mars and earth
At least two planets in our solar system have polar ice caps: Earth and Mars. On Earth, the North and South Poles have ice caps, while Mars has polar ice caps at its North and South Poles as well.

The sun
Earth and Mars are the only ones.
Mars and Earth are the two planets in the solar system that have ice caps. Mars has polar ice caps made of water and carbon dioxide, while Earth has polar ice caps made of ice and snow.
Yes, Neptune does have polar caps. Like Earth and other planets with atmospheres, Neptune's polar regions have icy caps composed of a mixture of water, ammonia, and methane ice. These polar caps experience seasonal variations as Neptune orbits the Sun.
Rain on the polar ice caps? Probably not; snow would be more common.
No.
