Detailed explanation-1: -Due to cryosphere melts, a large amount of cold fresh water empties into the sea. It will change the salinity and temperature of the ocean, and affect the global thermohaline circulation and climate change.
Detailed explanation-2: -Changes in the amount of sea ice can disrupt normal ocean circulation, thereby leading to changes in global climate. Even a small increase in temperature can lead to greater warming over time, making the polar regions the most sensitive areas to climate change on Earth.
Detailed explanation-3: -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-4: -The cryosphere has frozen water, ice, and glaciers. The cryosphere also interacts frequently with the hydrosphere because it draws water from the hydrosphere and freezes it during cold temperatures. Warmer temperatures cause the cryosphere to melt and release water back to the hydrosphere.
