JN Analysis:

1. Section 6A :The Supreme Court, in a 4-1 majority decision, upheld the constitutional validity of Section 6A of the Citizenship Act, 1955, which was introduced following the Assam Accord. This provision grants citizenship to individuals who entered Assam between January 1, 1966, and March 25, 1971. While Chief Justice DY Chandrachud, along with Justices Surya Kant, MM Sundresh, and Manoj Misra, supported the decision, Justice JB Pardiwala dissented, arguing that Section 6A was unconstitutional.

   
   

   The Court stated that the Assam Accord was a political resolution to the issue of illegal immigration from Bangladesh, and that the presence of diverse ethnic groups does not violate Article 29(1) of the Constitution.

The Assam Accord is a peace agreement signed on August 15, 1985, between the Government of India and the All Assam Students Union (AASU) to resolve the Assam agitation. The agitation was a long-running movement against illegal immigration from Bangladesh to Assam.

2.Marine Heatwave: Ocean eddy currents are responsible for significant temperature fluctuations in the deep sea, creating extreme heat and cold events in the depths, which are rich in marine life and host the planet’s largest migration.

According to recent research published in Nature, almost half of the heatwaves and cold spells reaching ocean depths between 200 and 1,000 meters are caused by these swirling currents, which carry warm or cold water.

As global ocean temperatures rise, these heatwaves and cold spells are becoming more severe, posing risks to marine ecosystems in the twilight zone. Monitoring these deep-sea temperature changes is difficult, as satellites cannot measure below the surface.

However, technologies like long-term moorings and Argo floats have provided essential data, revealing that eddy currents significantly contribute to temperature extremes in mid-latitude oceans.

These findings suggest that as oceans warm, stronger eddies may amplify temperature changes at greater depths, potentially threatening marine life in these regions.

• Ocean eddy currents, swirling currents of water, are responsible for creating extreme heat and cold events in the deep sea.

• These events occur between 200 and 1,000 meters depth, regions rich in marine life and known for hosting the planet's largest migration.

• The findings suggest that as oceans warm, stronger eddy currents may amplify temperature changes at greater depths.

• This could potentially threaten marine life in these regions.
