2, melting of glacier
3, submerged og coastal areas
Answer:
ocean warming
thermal expansion
coastal Erosion
warning bottom water
...etc
Explanation:
Ocean Warming: Most of the additional heat generated by rising levels of CO2 in the atmosphere is absorbed by the oceans. As a result, sea surface temperature is rising and already causing:
Thermal Expansion: As its temperature increases, seawater expands, contributing to sea level rise, changes in ocean circulation and higher seabed water temperature which may be damaging and pose the dangers described below:
Coastal Erosion: Rise in sea level, combined with other factors such as stronger wind events and loss of natural barriers protecting the coastline, result in increased coastal erosion endangering infrastructure, buildings and other facilities located in close proximity to the coastline.
Arctic Erosion: The Arctic ocean is warming, resulting in stronger storm activity and reduced sea ice formation, both contributing to erosion of coastlines hitherto kept stable by permafrost and sea ice reducing wave action. This causes increased exposure and thawing of methane (CH4) bearing sediments and yedoma resulting in emission of this gas and its oxidation to CO2, contributing to its rising presence in the atmosphere and further global warming.
Warmer bottom water: This is accelerating melting of ice enabling faster flow from glaciers discharging to the oceans and erosion of the marine ice sheet covering the West Antarctic archipelago – both causing sea level rise to accelerate and reducing stability of the ice sheet.
Warming seawater, particularly where shallow such as that covering the East Siberian Arctic Shelf, causes thawing of permafrost sediments containing CH4, which is being released directly to the atmosphere, contributing to accelerated global warming.
