GEOLOGY

Detailed explanation-1: -When glaciers melt, because that water is stored on land, the runoff significantly increases the amount of water in the ocean, contributing to global sea level rise.

Detailed explanation-2: -When warming temperatures gradually melt sea ice over time, fewer bright surfaces are available to reflect sunlight back into the atmosphere. More solar energy is absorbed at the surface and ocean temperatures rise. This begins a cycle of warming and melting.

Detailed explanation-3: -Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms.

Detailed explanation-4: -Polar ice caps are melting as global warming causes climate change. We lose Arctic sea ice at a rate of almost 13% per decade, and over the past 30 years, the oldest and thickest ice in the Arctic has declined by a stunning 95%.

Detailed explanation-5: -Rising temperatures cause ice shelves to break up-as they are floating already this will not affect sea levels, it may cause the glaciers behind them to speed up their flow-rate considerably. These glaciers will add to sea-level rise if they melt.
