- Antarctic sea ice peaks in September (end of southern winter); Arctic sea ice peaks in March
- Floating sea ice melting does not raise sea level much; melting of land-based ice sheets and glaciers does
- Antarctic Treaty was signed in 1959 and came into force in 1961

How the exam will ask it
ಪ್ರಿಲಿಮ್ಸ್
- Statement: The Antarctic sea ice extent reaches its annual maximum in September, whereas the Arctic sea ice reaches its maximum in March. (Correct)
- Statement: Melting of floating sea ice contributes as much to global sea level rise as melting of the Antarctic ice sheet on land. (Incorrect)
- Statement: India's Maitri and Bharati are research stations located in Antarctica. (Correct)
ಮೇನ್ಸ್
GS-I/III (Geography; Environment): Declining Antarctic sea ice signals climate change impacts on polar systems, weakening the albedo effect and affecting ocean circulation and weather patterns, including monsoon teleconnections. The Antarctic Treaty system and India's Indian Antarctic Act, 2022 provide the governance and research framework. The way forward is sustained polar monitoring, emission cuts under the Paris Agreement and strengthened scientific cooperation.

- ಕೇಂದ್ರ ಸಚಿವ ಸಂಪುಟದ ನಿರ್ಣಯದ ಮೂಲಕ
ಉತ್ತರ ನೋಡಿ
ಉತ್ತರ: D — ಕೇಂದ್ರ ಸಚಿವ ಸಂಪುಟದ ನಿರ್ಣಯದ ಮೂಲಕ ಸರಿಯಾದ ಉತ್ತರ. ನೀತಿ ಆಯೋಗ ಸಾಂವಿಧಾನಿಕವೂ ಅಲ್ಲ, ಶಾಸನಬದ್ಧವೂ ಅಲ್ಲ; ಇದನ್ನು 2015ರ ಜನವರಿ 1ರಂದು ಕೇಂದ್ರ ಸಂಪುಟದ ಕಾರ್ಯಾಂಗ ನಿರ್ಣಯದ ಮೂಲಕ ರಚಿಸಲಾಯಿತು.
