4. Impact of Greenhouse Gas Emissions on Satellite Sustainability

Context: A groundbreaking study published in Nature Sustainability has revealed a critical link between rising greenhouse gas (GHG) emissions and the long-term sustainability of satellites in Earth’s orbit. The study warns that increasing emissions could significantly reduce the number of satellites that can safely operate in space, posing a challenge for global communications, navigation, and scientific research.

How Greenhouse Gas Emissions Affect Earth’s Upper Atmosphere:

The upper atmosphere comprises the mesosphere (50-85 km) and the thermosphere (85-600 km).

  • Rising GHG levels cause more infrared radiation to escape into space, leading to cooling and contraction of the atmosphere.
  • Atmospheric contraction reduces air density in Low Earth Orbit (LEO), which affects satellite movement.
  • Lower air density leads to weaker atmospheric drag, allowing space debris to remain in orbit longer.
  • The accumulation of non-deorbiting debris increases the risk of satellite collisions, worsening space congestion and making future satellite missions more challenging.

Projected Impact on Satellite Sustainability:

Researchers from MIT Cambridge analyzed different emission scenarios, using greenhouse gas levels from the year 2000 as a baseline. Their findings indicate:

  • Under the worst-case emission scenario (SSP5-8.5), the number of sustainable satellites in LEO could drop by 50-66% by 2100.
  • Deorbiting rates of satellites and debris are expected to decline under moderate-to-high CO₂ emission scenarios, further exacerbating congestion in orbit.

Understanding the Shared Socio-economic Pathway (SSP5-8.5):

The SSP5-8.5 scenario is one of the five Shared Socioeconomic Pathways (SSPs) used in climate modeling by the Intergovernmental Panel on Climate Change (IPCC). It represents an extreme high-emission future with:

Key Features:

Severe Climate Impact

  • CO₂ concentration rises drastically, leading to a global temperature increase of 4-5°C by 2100.
  • More frequent extreme weather events, rising sea levels, and biodiversity loss.

Fossil Fuel Dependency

  • Energy demand continues to be met by coal, oil, and gas.
  • Minimal adoption of renewable energy, leading to worsening environmental conditions.

What Lies Ahead?

  • If GHG emissions continue at current rates, the space environment will face unprecedented challenges:
  • Increased risk of satellite collisions due to prolonged orbital debris lifespan.
  • Higher costs and risks for future satellite launches and operations.
  • Potential disruptions in global satellite-dependent systems, including GPS, climate monitoring, and communication networks.

Urgent Action is Needed!

  • The study underscores the need for sustainable space management, reduced emissions, and better debris mitigation strategies to ensure satellite sustainability for future generations.

Context: Experts and anthropologists are advocating for a paradigm shift in how tribes are identified in India. Instead of a rigid binary classification, they propose a “spectrum of tribalness” that assesses communities on multiple dimensions.

This demand gains significance amid rising claims for Scheduled Tribe (ST) status, including those by the Meitei community in Manipur.

Obsolete Criteria: A Need for Change

Currently, the Union government follows the Lokur Committee (1965) criteria, which include:

  • Primitive traits
  • Distinctive culture
  • Geographical isolation
  • Shyness of contact with the larger community
  • Backwardness

However, experts argue that these criteria are outdated, condescending, and ineffective. No community fully meets these definitions, making them unsuitable for modern policy decisions.

A New Approach: Spectrum-Based Classification:

Scholars propose moving away from rigid criteria and introducing a matrix or spectrum-based system with weighted indicators to determine a community’s degree of tribalness.

Both the Anthropological Survey of India (AnSI) and the National Commission for Scheduled Tribes (NCST) are actively working on a systematic classification tool for better assessment.

Proposed Indicators for Tribal Identity:

Experts suggest incorporating both tangible and intangible aspects, including:

  • Social institutions – Marriage patterns, kinship structures, classification of relatives
  • Rituals and traditions
  • Language and dialects
  • Material culture – Traditional headgear, weaponry, artifacts
  • Self-identification by the community itself

A potential classification tool may include over 150 indicators, providing a more holistic approach than the existing five criteria.

Concept Note & Policy Impact:

  • A concept note highlights the challenges in defining tribes and emphasizes the need for a refined classification system. This tool will enable Tribal Research Institutions (TRIs) to prepare accurate ethnographic reports, aiding in policymaking and governance.

Rising Demands for ST Status & Social Conflicts:

  • Currently, India recognizes 756 ST entries, including sub-entries. Since the 2011 Census, 27 new communities have been added. However, hundreds of communities continue to demand ST status, leading to inter-community tensions—for instance, the Meitei vs. Kuki-Zo & Naga tribes in Manipur.

Civilizational vs. Evolutionary Approach:

  • Experts recommend shifting from an evolutionary model (used in Australia and China) to a civilizational or historical model. This ensures that communities are understood as they perceive themselves, rather than being categorized as the “other” by external observers.

Conclusion: Towards a Fair and Inclusive System

A revised classification framework will enable better governance, equitable distribution of benefits, and conflict resolution. The focus should be on cultural identity, historical factors, and self-identification, rather than relying on outdated colonial-era definitions.

This progressive approach will help ensure that tribal communities receive the recognition and support they truly deserve.

Context: In recent months, deep-sea creatures like the anglerfish and oarfish, typically found in the ocean’s darkest depths, have been appearing near the surface in various locations. This unusual phenomenon has sparked scientific inquiry and public concern, with some linking it to climate change, seismic activity, and oceanic disruptions.

The Black Sea Devil: A Rare Surface Encounter:

One of the most astonishing sightings occurred in February 2025, when the Black Sea Devil anglerfish was filmed alive near the surface off the coast of Tenerife.

Unique Features of the Anglerfish:

  • Resides in the bathypelagic zone (Midnight Zone), where sunlight never reaches.
  • Uses a bioluminescent lure to attract prey.
  • Has razor-sharp teeth and an expandable stomach to consume prey twice its size.
  • Exhibits extreme sexual dimorphism—males, significantly smaller, attach to females as permanent parasites.

The Oarfish: A Harbinger of Disaster?

The oarfish, a long, ribbon-like deep-sea fish, has been linked to earthquake predictions in folklore.

Myth vs. Science

  • In Japanese folklore, the oarfish is called Ryūgū no Tsukai or “Messenger of the Sea God”.
  • Sightings occurred before the 2011 Fukushima earthquake, fueling beliefs that they predict seismic activity.
  • Recent sightings in Baja California and the Canary Islands have reignited similar fears.

Scientific Facts about Oarfish:

  • Typically found at depths of 200 to 1,000 meters.
  • Holds the title of longest bony fish, reaching up to 36 feet (11 meters).
  • Swims using amiiform movement, undulating its dorsal fin while keeping its body straight.
  • Feeds on zooplankton, shrimp, jellyfish, and small fish.

Scientific Explanations: Why Are Deep-Sea Creatures Rising?

While folklore suggests these sightings foretell disasters, scientists offer logical explanations:

1. Climate Change & Warming Oceans:

  • The ocean absorbs nearly 90% of excess heat from global warming, affecting marine currents and oxygen levels.
  • Deep-sea creatures may be forced into shallower, cooler waters to survive.

2. Underwater Seismic Activity:

  • Some researchers believe seismic shifts release gas bubbles, electrostatic charges, or toxic compounds like hydrogen peroxide.
  • These disturbances could disorient deep-sea species, causing them to surface.

3. El Niño & La Niña Effects:

  • These climate cycles alter temperature and ocean currents, leading to unpredictable marine movements.

4. Increased Human Observation:

  • With advancements in technology and social media, rare deep-sea sightings are now more widely documented, giving the impression that they are happening more frequently than before.

Conclusion: A Wake-Up Call from the Ocean?

The rise of deep-sea creatures to the surface is a rare but growing phenomenon. Whether it signals ecological distress, climate change impacts, or simply an increase in human awareness, it underscores the need for deeper oceanic research.

While folklore and myths add an element of mystery, science provides critical insights—suggesting that these creatures may be revealing hidden changes in the planet’s most uncharted realm: the deep sea.
