Sea level rise
Sea level rise is one of the most significant and well-known effects of climate change. It is caused by the thermal expansion of ocean water as it warms, and by the melting of glaciers and ice sheets. Antarctica is a major contributor to sea level rise, as it contains the largest ice sheet on Earth.
The melting of the Antarctic ice sheet is accelerating, and this is contributing to sea level rise at an increasing rate. In the past century, global sea levels have risen by about 20 centimetres. By the end of this century, they are projected to rise by a further 30-60 centimetres. This may not sound like much, but it can have a significant impact on coastal communities.
Sea level rise can cause flooding, erosion, and other damage to coastal infrastructure. It can also displace people and businesses, and disrupt ecosystems.
Cause | Effect |

Thermal expansion of ocean water | Sea level rise |
Melting of glaciers and ice sheets | Sea level rise |
Sea level rise is a serious threat to coastal communities around the world. It is important to take action to reduce greenhouse gas emissions and mitigate the effects of climate change.
Ocean acidification
Ocean acidification is the decrease in the pH of the Earth’s oceans, caused by the uptake of carbon dioxide from the atmosphere. The burning of fossil fuels, such as coal, oil, and gas, is the primary source of carbon dioxide emissions. Other sources include deforestation and agriculture.
The Southern Ocean surrounding Antarctica is particularly vulnerable to ocean acidification because it is cold and absorbs carbon dioxide more easily than warmer waters. As the Southern Ocean becomes more acidic, it can have a number of negative impacts on marine life.
- Reduced calcification: Ocean acidification makes it more difficult for marine organisms to build and maintain their shells and skeletons. This can have a negative impact on a variety of marine life, including shellfish, corals, and plankton.
- Impaired reproduction: Ocean acidification can also impair the reproduction of marine organisms.For example, some fish species have been shown to produce fewer eggs in more acidic waters.
- Behavioral changes: Ocean acidification can also affect the behavior of marine organisms. For example, some studies have shown that fish exposed to acidic waters become less active and more likely to be preyed upon.
Ocean acidification is a serious threat to marine life in Antarctica. It is important to take action to reduce greenhouse gas emissions and mitigate the effects of climate change.
