Why in news
The National Snow and Ice Data Center reported that Arctic sea ice reached nearly 14.22 million square kilometers on March 10th, potentially ranking among the five lowest winter peaks ever recorded.
Background
The Arctic is warming at three to four times the global average rate. The shrinking ice cover threatens polar ecosystems and impacts species like polar bears and emperor penguins while opening new shipping lanes and resource access.

For Mains
Q. Discuss how the rapid melting of Arctic sea ice creates a dual challenge of ecological degradation and heightened geopolitical competition over maritime resources.
Dimensions to cover in your answer
- Ecological fragility: Habitat loss for polar species and disruption of fragile Arctic marine ecosystems
- Geopolitical friction: Competition over newly accessible shipping lanes and untapped sub-surface resources
- Climate feedback: Accelerated summer melting due to reduced albedo from diminished winter ice cover
