Melting ice sheets significantly contribute to rising sea levels, threatening coastal communities and ecosystems. This process can disrupt ocean circulation patterns, affecting global climate systems and weather patterns. Additionally, the loss of ice sheets can release stored greenhouse gases, further exacerbating climate change. As habitats change, biodiversity may decline, impacting wildlife and human populations reliant on these ecosystems.
20,000-400,000 years, caused by formation and melting of ice sheets.
When chunks of continental glaciers break off from the edges of ice sheets, they produce icebergs. These icebergs can vary significantly in size and can float in oceans or seas, eventually melting as they drift into warmer waters. The calving process also contributes to sea level rise and can have significant impacts on marine ecosystems. Additionally, the release of freshwater from melting icebergs can affect ocean circulation patterns.
Carbon dioxide and methane are the two greenhouse gases that have contributed to increasing ice melting in Greenland. These gases trap heat in the Earth's atmosphere, leading to rising temperatures and accelerated melting of ice sheets.
The winds that blow off the ice sheets of Antarctica and Greenland are known as katabatic winds. These downslope winds are dense and cold, originating from the high ice sheets and flowing towards lower elevations due to gravity. Katabatic winds can have significant impacts on local weather and climate.
The water source that will have the greatest impact on sea levels is the melting of polar ice sheets, particularly from Greenland and Antarctica. As global temperatures rise, the ice sheets are melting at an accelerated rate, contributing significantly to sea level rise. Additionally, the thermal expansion of seawater due to warming also adds to rising sea levels, but the melting ice sheets are more substantial in terms of volume.

Multiple factors led to the end of the last ice age around 11,700 years ago, including changes in Earth's orbit and tilt, increased solar radiation, and the release of greenhouse gases like carbon dioxide and methane from melting ice sheets and vegetation. These factors contributed to a gradual warming of the planet, melting the ice sheets and transitioning Earth into a warmer interglacial period.
CO2 is naturally released by melting polar ice and active volcanoes CH4 (methane) is also trapped in ice sheets
Melting ice turns the ice into water.
Polar ice caps form when snow accumulates over many years and compresses into ice under its own weight. Cold temperatures prevent the ice from melting, allowing it to build up and form extensive sheets of ice at the poles. These ice sheets can grow thicker over time as more snow accumulates on top and compacts into ice.
In the north, I believe it's becoming less salty, in part due to the melting of the ice sheets on Greenland.
