2021 GS1 Answer

Q. How do the melting of the Arctic ice and glaciers of the Antarctic differently affect the weather patterns and human activities on the Earth? Explain.

Question from UPSC Mains 2021 GS1 Paper

Model Answer: 

The melting of Arctic ice and glaciers of the Antarctic due to climate change is a significant concern for the planet. The melting of ice leads to sea-level rise, which has severe consequences for human activities and weather patterns on Earth.

Effects of Melting Arctic Ice and Glaciers of the Antarctic on Weather Patterns and Human Activities

Melting Arctic Ice

The Arctic is warming at a much faster rate than the rest of the world. The melting of Arctic ice has several effects on weather patterns and human activities, including:

  • The melting of Arctic ice leads to sea-level rise, which has severe consequences for low-lying areas around the world.
  • The reduction in ice cover leads to an increase in the absorption of solar radiation, which causes further warming.
  • The warming of the Arctic affects the jet stream, leading to more persistent weather patterns in certain areas, such as prolonged drought or heavy rainfall.
  • The melting of Arctic ice leads to changes in ocean circulation patterns, which can affect global weather patterns.
  • The reduction in ice cover in the Arctic has led to the opening of new shipping routes, which has economic benefits but also increases the risk of oil spills and other environmental hazards.
  • The melting of permafrost in the Arctic leads to the release of methane gas, which contributes to further warming.

Melting Glaciers of the Antarctic

The melting of glaciers in the Antarctic also has several effects on weather patterns and human activities, including:

  • The melting of glaciers in the Antarctic leads to sea-level rise, which has severe consequences for low-lying areas around the world.
  • The melting of glaciers leads to changes in ocean circulation patterns, which can affect global weather patterns.
  • The melting of glaciers in the Antarctic leads to the release of fresh water, which can change the salinity of the ocean and affect ocean circulation patterns.
  • The melting of glaciers in the Antarctic affects the habitats of species that rely on sea ice, such as penguins and seals.
  • The melting of glaciers in the Antarctic can lead to the destabilization of ice shelves, which can cause them to collapse and release large amounts of ice into the ocean, leading to further sea-level rise.

Conclusion

The melting of Arctic ice and glaciers of the Antarctic due to climate change has severe consequences for the planet. The effects of melting ice on weather patterns and human activities are complex and far-reaching. It is essential to take immediate action to mitigate the impact of climate change to avoid catastrophic consequences.
