From UPSC perspective, the following things are important :
Prelims level: Civil Aviation Safety Advisory Council, DGCA and other related departments and mandates
Mains level: Aviation sector, safety concerns and reforms
Central idea
- In 2010, a tragic accident at Mangalore airport claimed the lives of 158 people. Despite prior warnings and PILs filed by the Environment Support Group, the concerned authorities neglected to address safety concerns regarding the airport’s second runway. It highlights the lack of accountability and transparency in the system, the failure to learn from past accidents, and the urgent need for reforms in India’s aviation sector.
Background
- In 1997, the Environment Support Group raised concerns about the inadequacy of Mangalore airport’s second runway during emergencies. However, the PIL filed by the NGO was dismissed by the Karnataka High Court.
- In 2002, another PIL emphasized the potential dangers of the runway, but it faced the same fate. Dissatisfied with the verdict, the group approached the Supreme Court, which ruled that the government must adhere to applicable laws and environmental norms during airport construction
- Following the Mangalore crash, the Ministry of Civil Aviation established the Civil Aviation Safety Advisory Council (CASAC) to identify deficiencies and propose corrective measures.
- CASAC pointed out the court of inquiry’s failure to identify critical errors and suggested improvements, particularly at airports like Mangalore and Calicut. However, their warnings were disregarded by the Ministry and the DGCA.
- The subsequent accident at Calicut on August 7, 2020, claiming 21 lives, further exposed the disregard for safety concerns.
- The recommendations made by the committee formed after the accident remain unimplemented due to prioritizing commercial interests over safety.
Lessons ignored
- Neglecting Compliance with Laws and Norms: Government agencies responsible for airport construction failed to comply with applicable laws and environmental norms, as mandated by the Supreme Court. This negligence resulted in violations that ultimately led to the tragic crash.
- Dismissing Expert Opinions: The Supreme Court’s dismissal of the PIL that highlighted the violations and safety concerns surrounding Mangalore airport indicates a reluctance to hold government agencies accountable. The judiciary’s unwillingness to intervene despite expert opinions undermined the pursuit of justice and prevention of future accidents.
- Lack of Accountability: The blame for accidents was often placed solely on pilots, while the systemic deficiencies and regulatory failures were overlooked. The absence of accountability within the aviation sector perpetuated a culture of negligence and hindered efforts to address underlying safety issues.
- Failure in Accident Investigations: The investigations conducted by the DGCA and AAIB failed to identify the root causes of accidents and provide effective preventive measures. Instead of rectifying systemic shortcomings, investigations often resorted to blaming pilot error, leaving the real issues unresolved.
- Neglecting Recommendations: The warnings and recommendations put forth by the Civil Aviation Safety Advisory Council (CASAC) were disregarded by the Ministry of Civil Aviation and the DGCA. The failure to implement necessary safety measures, such as Runway End Safety Areas (RESA), despite expert advice, highlights a disregard for passenger safety.
- Prioritizing Commercial Interests: Commercial interests were given precedence over safety considerations, as implementing certain safety measures would have affected the runway length and payload. This compromise on safety standards underscores the need to prioritize the well-being of passengers over commercial gains.
Role and responsibilities of Civil Aviation Safety Advisory Council (CASAC)
- Identify Deficiencies: CASAC is tasked with identifying deficiencies in safety measures, regulations, infrastructure, and operational practices across airports, airlines, and regulatory bodies. It conducts thorough assessments and inspections to pinpoint areas where safety standards may be compromised.
- Provide Recommendations: Based on its assessments, CASAC formulates recommendations and proposes corrective measures to address the identified deficiencies. These recommendations cover a wide range of aspects, including operational procedures, infrastructure improvements, training programs, safety audits, and regulatory enhancements.
- Review Reports and Investigations: CASAC reviews accident investigation reports and court of inquiry findings related to aviation accidents and incidents. It examines these reports to determine if proper root cause analysis has been conducted and if adequate preventive measures have been recommended. CASAC ensures that critical errors or safety gaps are identified and addressed in the reports.

From UPSC perspective, the following things are important :
Prelims level: Ice-albedo feedback cycle, Climate change, global sea rise
Mains level: Decline in Antarctic sea ice, global sea rise and impact on weather patters, Need of immediate actions
Central Idea
- The recent record-breaking drop in Antarctic Sea ice extent on February 19 has raised significant concerns about the impacts of global warming. This worrying trend, accompanied by rising global temperatures, poses a threat to coastal cities and has far-reaching consequences for weather patterns and underwater ecosystems. As sea ice continues to melt and global sea levels rise, urgent action is needed to address the environmental challenges presented by this alarming decline.
Melting Sea Ice and Rising Sea Levels: A worrying trend
- Over the past six years, the Antarctic Sea ice cover has witnessed substantial declines, resulting in a rise in global sea levels.
- NASA reports that meltwater from Antarctic ice accounts for approximately one-third of the global average sea level rise since 1993.
- The sea ice extent in 2023 has often been notably lower than the levels seen in 2022, which had the second-lowest summer sea ice extent in Antarctica.
- The Antarctic Sea ice extent as of May 21, 2023, has significantly shrunk compared to the median extent between 1981 and 2010
- The April temperature in the Antarctic region in 2023 was 0.93°C higher than the 1910-2000 average for that month, marking the second-highest increase in the millennium.
Impact decline in Antarctic Sea ice on Global Weather and Ecosystems
- Weather Pattern Alterations: The Southern Ocean, surrounding Antarctica, plays a crucial role in transferring heat from the atmosphere to the global oceans. Increased melting of Antarctic sea ice introduces cold, fresh water into the ocean, disrupting the circulation patterns of hot, cold, fresh, and salty water globally. This alteration in temperature and density can subsequently affect weather patterns, including wind patterns, precipitation, and storm formation.
- Oceanic Currents and Nutrient Flows: Changes in water temperature and density due to melting sea ice can disrupt oceanic currents and nutrient flows. These currents are vital for distributing heat, nutrients, and oxygen across the world’s oceans. The disturbance in these flows can have cascading effects on marine ecosystems, impacting the distribution and availability of nutrients for various organisms.
- Impact on Underwater Ecosystems: Sea ice serves as a critical habitat for various organisms, including algae, krill, and other marine life. Diminishing sea ice reduces the availability of food and alters the feeding patterns and reproductive cycles of species dependent on these ecosystems. This disruption can have significant consequences for the entire Antarctic food chain, affecting species such as whales, seals, penguins, and seabirds.
- Altered Albedo Effect: The decline in sea ice coverage reduces the Earth’s albedo effect. Albedo refers to the ability of a surface to reflect sunlight back into space. Sea ice has a high albedo, meaning it reflects a significant portion of incoming solar radiation. As sea ice diminishes, darker ocean water absorbs more solar radiation, leading to increased warming and amplifying the overall warming trend.
- Feedback Loops: The impacts of melting sea ice create feedback loops that exacerbate the effects of climate change. For example, as sea ice melts, more heat is absorbed by the ocean, further accelerating the melting process. These feedback loops contribute to the amplification of warming trends and the intensification of associated environmental changes.
Facts for prelims
What is ice-albedo feedback cycle?
- The ice-albedo feedback cycle, also known as the snow-ice albedo feedback, refers to a positive feedback mechanism that amplifies the effects of global warming. It involves the interaction between ice or snow cover and solar radiation.
- The albedo of a surface refers to its ability to reflect sunlight. Ice and snow have high albedo values, meaning they reflect a significant portion of incoming solar radiation back into space.
- This reflection helps to cool the Earth’s surface. However, when ice or snow melts, it reveals darker surfaces beneath, such as dark ocean water or land, which have lower albedo values. These darker surfaces absorb more solar radiation, leading to increased warming
- The ice-albedo feedback cycle operates in both polar regions, but it is particularly significant in the Arctic and Antarctic regions, where extensive ice and snow cover exist.
- The reduction in sea ice extent and the melting of glaciers and ice sheets contribute to this feedback mechanism, accelerating the warming trend and exacerbating the impacts of climate change.
Understand this way: How do the ice-albedo feedback cycle operate?
- Initial Warming: Due to various factors, including greenhouse gas emissions, the Earth’s temperature increases, leading to the melting of ice and snow cover.
- Reduced Albedo: As ice and snow melt, the reflective white surface is replaced by darker surfaces with lower albedo values. These surfaces absorb more solar radiation rather than reflecting it back into space.
- Increased Heating: The absorption of more solar radiation by darker surfaces results in increased heating of the Earth’s surface and atmosphere.
- Further Melting: The increased heating leads to more melting of ice and snow, further reducing the overall ice and snow cover.
- Amplification of Warming: With less ice and snow cover, more heat is absorbed, contributing to a positive feedback loop. The amplified warming results in further ice and snow melt, creating a cycle of increasing temperatures.

Impact of Rising Sea Levels on coastal communities around the worldwide
- Increased Flooding and Erosion: As sea levels rise, coastal areas are more susceptible to storm surges, high tides, and extreme weather events. This puts low-lying regions, including coastal cities and communities, at greater risk of inundation, property damage, and displacement of residents.
- Coastal Infrastructure Vulnerability: Increased flooding and erosion can lead to the degradation and loss of critical infrastructure, disrupting transportation, energy supply, and essential services. This vulnerability can have substantial economic, social, and public safety implications.
- Threat to Freshwater Resources: Rising sea levels can infiltrate freshwater sources and contaminate underground aquifers, particularly in coastal regions where freshwater and saltwater interfaces occur. This intrusion of saltwater can compromise drinking water supplies, agricultural irrigation, and ecosystems dependent on freshwater resources, exacerbating water scarcity issues.
- Displacement of Communities: As coastal areas become uninhabitable due to sea-level rise and increased flooding, communities may face the prospect of forced relocation. This displacement can result in the loss of homes, cultural heritage, and livelihoods, leading to social disruption, economic challenges, and psychological impacts on affected populations.
- Ecological Impacts: Coastal ecosystems, including mangroves, coral reefs, and wetlands, provide critical habitats, buffer against storms, and support biodiversity. Rising sea levels can inundate and degrade these ecosystems, leading to the loss of valuable ecological services, increased vulnerability to coastal hazards, and reduced coastal resilience.
- Economic Consequences: The impacts of sea-level rise and coastal flooding can disrupt tourism, fishing, and shipping industries, leading to economic losses, job displacements, and decreased productivity. Additionally, the costs of coastal protection measures and infrastructure adaptations to rising sea levels can place a significant burden on local economies and governments.
Way Forward
- Strengthening International Cooperation: Collaborate at global forums to address climate change and its impact on Antarctica, emphasizing the need for reduced emissions and sustainable practices.
- Enhanced Monitoring and Research: Invest in further research to understand the dynamics of melting sea ice, its impact on ecosystems, and potential mitigation strategies.
- Promoting Sustainable Practices: Encourage sustainable practices and responsible tourism in the Antarctic region to minimize human impact on the fragile ecosystem.
- Climate Resilience Planning: Develop robust climate resilience plans for coastal cities and communities, considering rising sea levels and potential threats posed by diminishing sea ice.

From UPSC perspective, the following things are important :
Prelims level: Comb Jellies, Neurons, Neural Network
Mains level: Not Much
Central Idea
- Comb jellies, or ctenophores, are marine animals with jelly-like bodies and iridescent combs.
- They represent an ancient animal lineage and have a distinct nervous system.
- A recent study published in Science examined the comb jelly nervous system and made surprising discoveries.
What are Comb Jellies?
- Comb jellies, also known as ctenophores, are marine animals that belong to the phylum Ctenophora. They are fascinating creatures with a unique and delicate appearance.
- Despite their name, comb jellies are not actually true jellyfish.
- They have a gelatinous, transparent body that is often luminescent and adorned with rows of cilia, or comb-like structures, which give them their characteristic shimmering appearance.
Findings of the new study
- The researchers aimed to investigate how nerve net neurons in comb jellies connect.
- Contrary to expectations, synapses (junctions between neurons) were absent in the nerve net.
- Instead, nerve-net neurons were continuously connected by a single plasma membrane.
Significance of ctenophores
- In the 1950s, electron microscopy confirmed the separate-cell nature of neurons connected by synapses.
- Ctenophores challenge this notion by having a syncytial nerve net, as observed in the new study.
- Ctenophores attracted attention due to their status as a potential early animal lineage.
- Whole-genome sequencing studies supported the theory that ctenophores branched off early in animal evolution.
Evolution of ctenophore nervous systems
- The evolution of ctenophore nervous systems remains unclear to biologists.
- Leonid Moroz proposed a controversial theory of independent nervous system evolution in ctenophores and other animals.
- Ctenophores exhibit a unique nervous system lacking classical neurotransmitter pathways and common neuronal genes.
- The absence of muscle-based movement and reliance on cilia might have driven the evolution of a different signal conduction system.
Questions for further research
- Researchers aim to study the development of nerve net neurons in ctenophores.
- They seek to determine if adult ctenophores retain syncytial nerve nets or develop synapses.
- The uniqueness of ctenophore nervous systems provides valuable insights into the evolution of the nervous system.
- Comparative analyses of unique animal systems like ctenophores aid in understanding neuronal function and treating disorders.
Conclusion
- Understanding the functional and evolutionary significance of syncytial nerve net neurons in ctenophores requires further research.
- This study serves as a crucial foundation for investigating the evolution of nervous systems in animals.
- Comparative studies on small marine creatures like ctenophores offer insights into the fundamental principles of brain function.
