GEOLOGY

Detailed explanation-1: -Global sea levels are rising as a result of human-caused global warming, with recent rates being unprecedented over the past 2, 500-plus years. Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers, and the expansion of seawater as it warms.

Detailed explanation-2: -Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.

Detailed explanation-3: -There is still some uncertainty about the full volume of glaciers and ice caps on Earth, but if all of them were to melt, global sea level would rise approximately 70 meters (approximately 230 feet), flooding every coastal city on the planet.

Detailed explanation-4: -Sea level rise Glacial melting has contributed to raising sea levels by 2.7 centimeters since 1961.

Detailed explanation-5: -The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems, causing coral bleaching and the loss of breeding grounds for marine fishes and mammals.
