2. World’s oceans near critical acidification level: report
Sub: Geo
Sec: Oceanography
Context:
- A new report from the Potsdam Institute for Climate Impact Research (PIK) warns that the world’s oceans are on the verge of becoming too acidic to sustain marine life or stabilize the climate.
Key Findings:
- The PIK’s report highlights nine critical factors essential for regulating Earth’s ability to sustain life.
- Six of these factors have already surpassed safe limits due to human activities.
- Ocean acidification is the next factor likely to breach its threshold, potentially becoming the seventh factor to cross the danger zone.
- Safe Boundaries Already Exceeded:
- Climate change
- Loss of species
- Loss of natural habitats
- Loss of freshwater resources
- Rising pollutants (plastics, chemical fertilizers)
- Ocean Acidification:
- Largely driven by increasing CO2 emissions from burning fossil fuels (oil, coal, gas).
- As CO2 dissolves in seawater, the oceans become more acidic.
- Even with rapid cuts in emissions, some ongoing acidification is inevitable due to the existing CO2 already absorbed by the oceans.
Impact of Acidification on Marine Life and Climate:
- Acidic water harms Corals, Shellfish, Phytoplankton (the base of many marine food chains)
- This disruption affects:
- Food supply for billions of people
- The ocean’s ability to absorb CO2, worsening global warming.
Tipping Points and Global Boundaries:
- Tipping points refer to thresholds beyond which changes become irreversible and catastrophic.
- If these points are crossed, billions of people and future generations could face devastating consequences.
- Interconnected Boundaries:
- All nine planetary boundaries are linked, meaning that breaching one limit can destabilize Earth’s entire life support system.
- Positive Opportunities:
- Addressing one issue, such as limiting global warming to 1.5°C, can lead to broader benefits across other environmental challenges.
Other Planetary Boundaries:
- Ozone Layer:
- The only boundary not close to being crossed.
- Damaged by man-made chemicals, it began to recover after these chemicals were banned in 1987.
- Air Pollution:
- Concerns about fine particles that can cause heart and lung diseases.
- Some improvement seen due to efforts like reducing pollutants from petrol and diesel cars, but risks remain in rapidly industrializing countries.

- Bektashi Muslims are Albania’s fourth-largest religious group, following Sunni Muslims, Orthodox Christians, and Catholics.
Purpose and Vision:
- Albanian Prime Minister Edi Rama announced the plan at the United Nations, stating that the goal is to transform the Bektashi World Centre in Tirana into a sovereign state.
- This new microstate aims to be a symbol of moderation, tolerance, and peaceful coexistence.
- Bektashi Community’s Response:
- The Bektashi Order praised the decision, emphasising that sovereignty would strengthen religious inclusion, harmony, and dialogue in an increasingly divided world.
Details of the Microstate:
- The new state will cover around 10 hectares (25 acres) in Tirana.
- Citizenship will be restricted to members of the Bektashi clergy and those involved in the administration of the state.
- The microstate’s government will be led by the Bektashi leader and a council responsible for both religious and administrative governance.
About the Bektashi Order:

- Veneration of ʿAlī, the son-in-law of Muhammad.
- Reverence for the Twelve Imams and other syncretic beliefs.
- In the 15th century, the order became politically influential, especially through its connection with the Janissary Corps.
- Following the establishment of modern Turkey, Kemal Atatürk banned non-state religious institutions, leading to the Bektashi headquarters relocating to Albania.
- Salih Nijazi was the last Dede in Turkey and the first in Albania.
- The Bektashi Order played a role in Albanian politics, with some members, including Ismail Qemali, participating in the Albanian National Awakening.
- In the early 20th century, many Bektashi leaders relocated to Albania after being banned in Turkiye by Mustafa Kemal Ataturk, the founder of modern Turkey.
Beliefs and Influences:

- The Shia belief system circulating in Anatolia from the 14th to 16th centuries.
- Balım Sultan systematized and structured the Bektashi rituals and practices in the 16th century.
Bektashi Population:
- Estimates of the Bektashi population range between 7 million (2005 estimate) and 20 million (more recent studies).
- In Albania:
- Bektashis make up 9% of the Muslim population and 5% of the overall population.
- In Turkey:
- There are approximately 12.5 million Bektashis.
- Bektashis are predominantly found in Anatolia, the Balkans, and among Ottoman-era Greek Muslim communities.

Sub :Polity
Sec: Legislation in news
Why in News
The Supreme Court of India has delivered a landmark judgment on child sexual exploitation. It held that merely viewing or possessing child sexual exploitative and abuse material (CSEAM) is a criminal offense. The judgment calls for legislative amendments to reflect the seriousness of the crime and proposes replacing the term “child pornography” with a more accurate term—CSEAM.
Criminalization of CSEAM Viewing and Possession
The Supreme Court clarified that viewing, downloading, storing, distributing, or displaying pornographic material involving children attracts criminal liability under the Protection of Children from Sexual Offenses (POCSO) Act and the Information Technology (IT) Act.
Challenge to the High Court’s Ruling: The verdict overturns a previous ruling by the Madras High Court, which had concluded that mere possession or private viewing of child pornographic material was not an offense under POCSO.
Protection of Children from Sexual Offences (POCSO) Act, 2012
It was enacted to protect the children from offences of sexual assault, sexual harassment and pornography with due regard for safeguarding the interest and well-being of children.
It defines a child as any person below eighteen years of age and regards the best interests and welfare of the child as a matter of paramount importance at every stage, to ensure the healthy physical, emotional, intellectual and social development of the child.
It defines different forms of sexual abuse, including penetrative and non-penetrative assault, as well as sexual harassment and pornography.
It deems a sexual assault to be “aggravated” under certain circumstances, such as when the abused child is mentally ill or when the abuse is committed by a person in a position of trust or authority like a family member, police officer, teacher, or doctor.
It also casts the police in the role of child protectors during the investigative process.
The Act stipulates that a case of child sexual abuse must be disposed of within one year from the date the offence is reported.
It was amended in August 2019 to provide more stringent punishment, including the death penalty, for sexual crimes against children.
Amendment of POCSO Act: The Supreme Court urged Parliament to amend the POCSO Act by replacing the term “child pornography” with “Child Sexual Exploitative and Abuse Material” (CSEAM). This change aims to avoid the trivialization of the crime, as the term “pornography” is often associated with consensual adult acts, which undermines the gravity of child sexual abuse.
Section 15 of the POCSO Act: The court pointed out that Section 15 of the POCSO Act criminalizes the possession and storage of child pornographic material. Merely keeping such material without deletion can be construed as intent to distribute it.
Information Technology (IT) Act Related to Child Pornography:
Section 67B: Punishes publishing, transmitting, or browsing child pornographic material online.
Criminalizes: Creation, collection, and distribution of child pornographic content.
Online facilitation or enticement of children for sexual acts.
Penalty: Up to 5 years imprisonment and a fine of ₹10 lakh for the first conviction; up to 7 years and a ₹10 lakh fine for subsequent offenses.
Section 67: Covers punishment for publishing or transmitting obscene material, which includes child pornography, in electronic form.
Section 69A: Empowers the government to block websites that host child pornographic content.
Section 72: Imposes penalties for unauthorized access to any personal information, including images or videos involving child pornography.
Immediate Government Action
Promulgation of Ordinance: The court suggested that the government should promulgate an ordinance to expedite the adoption of the proposed terminological changes while awaiting parliamentary action.
Ordinance An ordinance is a temporary law issued by the President (at the central level) or Governor (at the state level) when the legislature is not in session. Article 123: Empowers the President to promulgate ordinances during Parliament recess. Article 213: Empowers the Governor to issue ordinances when the State Legislature is not in session. Conditions for Issuance: Legislature must not be in session. Immediate action is required, and the President/Governor must be satisfied with the necessity. Duration: Ordinance must be approved by Parliament/State Legislature within 6 weeks of reassembly, or it will cease to operate. Limitations: Cannot be issued to amend the Constitution. Can be challenged in court if issued without genuine necessity (judicial review). DC Wadhwa Case (1987) – Supreme Court ruled that re-promulgation of ordinances without legislative approval is unconstitutional. |
Court Directives: The Supreme Court also directed lower courts across India to use the term CSEAM in their judgments and orders.
9. Massive Greenland Landslide: Triggering Nine-Day Seismic Waves Worldwide
Sub :Geo
Sec: Geomorphology
Why in News
On September 16, 2023, seismic stations worldwide detected an unusual signal that puzzled scientists. Unlike typical earthquakes, this event was caused by a massive landslide in Greenland’s Dickson Fjord. The landslide displaced water, triggering a mega-tsunami and sending seismic waves reverberating across the globe for nine days. The incident highlights the increasing risks posed by melting glaciers in a warming climate.
The Landslide Event
Location: Dickson Fjord is situated in eastern Greenland, part of the vast fjord systems of the Arctic region.
Depth and Width: The fjord has an approximate depth of 540 meters and a width of 2.7 kilometers, which makes it capable of containing large volumes of water and rock displaced by landslides.
Mega-Tsunami Site: In September 2023, Dickson Fjord was the site of a massive landslide that triggered a 200-meter-high mega-tsunami, which displaced approximately 25 million cubic meters of ice and rock.
About Fjords: A fjord is a long, narrow, deep inlet of the sea between high cliffs or steep slopes, typically formed by the process of glacial erosion.
Geographical Distribution: Fjords are most commonly found in high-latitude regions, especially in areas with a history of glaciation.
Major Fjord Regions:
Norway: Known for having some of the longest fjords in the world.
Greenland: Contains some of the largest fjords, such as Dickson Fjord.
New Zealand: Famous fjords like Milford Sound.
Canada: Fjords are found along the coast of British Columbia and eastern Quebec.
Formation of Fjords: Fjords are formed by the process of glacial erosion. Over time, glaciers carve deep valleys into the Earth’s crust, which later get filled with seawater when the glaciers retreat.
There are two main ways fjords are formed:
A. Glacial Carving: As glaciers move slowly over the land, they erode the underlying bedrock. The glacier carves a U-shaped valley, which is characteristic of fjords. When the glacier retreats, the sea floods the valley, creating a fjord.
Key Feature: Fjords often have steep sides or cliffs and a flat valley bottom.
B. Tectonic and Glacial Interaction: In some cases, tectonic activity (such as the movement of Earth’s crust) causes the land to uplift, while glaciers further shape the landscape by carving valleys. This process results in deeper fjords and sometimes more complex fjord systems.
Example: Fjords in Norway and Greenland, where tectonic uplift contributed to their depth and steep slopes.
Key Features of Fjords:
Deep Inlets: Fjords can be extremely deep. For example, Sognefjord in Norway is over 1,300 meters deep.
Steep Cliffs: Fjords are typically surrounded by high, steep cliffs that can rise dramatically from the water.
U-Shaped Valleys: The valleys formed by fjords are U-shaped due to the glacier’s erosive action.
Long, Narrow Inlets: Fjords are long and narrow, with their length often extending deep inland.
Characteristics of Fjords:
Sill: Many fjords have a shallow area called a sill at their mouth, where the glacier’s terminal moraine (a pile of debris left by the glacier) restricts the water flow.
Seiche: Fjords can experience a phenomenon known as seiche, where waves reflect back and forth within the inlet, as seen in the Dickson Fjord after the 2023 landslide.
Cold-water Coral Reefs: Some fjords, such as those in Norway, are home to unique cold-water coral reefs.
About Sloshing Waves (Seiche Effect): The mega-tsunami waves reflected back and forth within the 540-meter-deep, 2.7-kilometer-wide fjord. These oscillating waves created a “seiche” that persisted for over nine days, with a maximum wave amplitude of 7.4 meters and an oscillation frequency of 11.45 MHz.
Seiche: A seiche is a standing wave that oscillates in a semi-enclosed or fully enclosed body of water, such as lakes, bays, swimming pools, or ocean harbours.
Causes: Strong winds or rapid changes in atmospheric pressure push water from one side of the water body to the other. When the wind stops, water rebounds and oscillates back and forth.
Other Triggers: Earthquakes, Tsunamis and Severe Storm Fronts
Characteristics:
Oscillation: Water continues to slosh back and forth for hours or even days after the initial trigger.
Occurrence: Happens in enclosed or semi-enclosed water bodies like lakes, bays, and ocean shelves.
Seismic Waves Across the Planet: The landslide’s energy rang the Earth’s surface, creating seismic waves that were detected globally. These waves matched the strange, single-frequency seismic signatures recorded by stations, confirming the landslide as the source.
About Seismic Waves: There are several different kinds of seismic waves, and they all move in different ways. The two main types of waves are body waves and surface waves.
Body waves can travel through the earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water
The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to ‘arrive’ at a seismic station. The P wave can move through solid rock and fluids,like water or the liquid layers of the earth. It pushes and pulls the rock it moves through just like sound waves push and pull the air.
The second type of body wave is the S wave or secondary wave, which is the second wave felt in an earthquake. An S wave is slower than a P wave and can only move through solid rock, not through any liquid medium. It is this property of S waves that led seismologists to conclude that the Earth’s outer core is a liquid.
S waves move rock particles up and down, or side-to-side–perpendicular to the direction that the wave is traveling in (the direction of wave propagation)
10. Enabling Transit-Oriented Development: A Path to Sustainable Urban Growth
Sub :Geo
Sec: Eco geo
Why in News
India is undergoing a transportation revolution with massive investments in metro rail projects, leading to a renewed focus on Transit-Oriented Development (TOD). TOD has gained attention as a critical approach for integrating urban transport and land use, promoting sustainable economic growth, and addressing challenges such as traffic congestion and pollution in major cities like Bengaluru.
What is TOD?
Transit Oriented Development (TOD) is an innovative urban planning concept that focuses on optimizing land use around public transit infrastructure. It encourages mixed-use, compact development to reduce dependence on private vehicles and enhance accessibility to public transport. TOD aims to achieve sustainable mobility, enhance urban livability, and stimulate economic growth.
National Transit Policies and Investments
Investment in Urban Mobility: India has allocated ₹3 trillion (2022-2027) for metro rail projects across the country.
National TOD Policy (2017): The Indian government introduced the National Transit Oriented Development (TOD) Policy and Metro Rail Policy to integrate transit systems with urban planning.
The Union Budget 2024-25 has proposed the formulation of Transit-Oriented Development (TOD) plans and strategies for 14 large cities with populations exceeding 30 lakhs.
Metro Expansion: Currently, 27 Indian cities are building metro rail systems, with others adopting bus-based and rail-based rapid transit systems.
Investment in public transportation can generate jobs and economic returns that are 5-7 times the initial outlay.
The focus on TOD aims to enhance productivity, reduce traffic congestion, and achieve low-carbon growth.
The World Bank’s 3V Framework guides the successful implementation of TOD by evaluating the following factors:
Node Value: The significance of a station in the transit network based on passenger traffic and connectivity with other transport modes.
Place Value: The quality and attractiveness of the area, including mixed land use and the availability of essential services like healthcare and education.
Market Potential Value: The unrealized economic potential measured by current and future job opportunities in the vicinity, alongside market vibrancy and demand.
Barriers for TOD Implementation
Property Constraints: Limited availability of large, compliant properties near metro stations and restrictive development regulations hinders business growth.
High Property Prices: Rising property costs near metro stations deter smaller businesses from locating in these areas.
Solutions for Optimizing TOD
Incentives for Businesses: Offering location-efficient incentives, such as tax subsidies or additional development rights, can encourage businesses to cluster near transit stations.
Public-Private Partnerships: Collaborations between government agencies and the private sector can fund TOD projects, particularly through mechanisms like value capture financing.
Nodal Agencies: A designated body can streamline TOD planning, ensuring effective coordination between stakeholders.
Examples – Global Cities
Hong Kong serves as a model TOD city, with 57% of jobs within 500 meters of a transit station, and 96% within 2 km. The city’s high transit usage (90% of motorized trips) and low car ownership have contributed to its 50% rise in Gross Value Added per capita over two decades.
Copenhagen, Denmark: The Finger Plan in Copenhagen incorporates TOD principles by ensuring suburban development aligns with rail lines, promoting compact growth and efficient use of public transport.
TOD in Bengaluru’s Future Master Plan
The revision of Bengaluru’s master plan presents an opportunity to prioritize job creation near transit hubs, connecting high-density job clusters and enhancing resource efficiency. This approach will balance economic development with environmental sustainability.

- The Supreme Court of India recently dismissed a public interest litigation (PIL) seeking to stop defence exports to Israel due to alleged war crimes in Gaza.
- The Court refrained from intervening, stating that foreign policy is not within its jurisdiction.
- However, the issue has broader implications beyond Israel, given India’s aspirations to become a major defence exporting nation.
Countries that curbed defence exports to Israel:
- Netherlands: Court ordered the government to block export of F-35 fighter jet parts to Israel, based on EU regulations prohibiting exports if there’s a risk of violations of international humanitarian law (IHL).
- United Kingdom: Reviewed Israel’s compliance with IHL under the Export Control Act and concluded there is a clear risk that exported arms could facilitate violations.
Legal Framework in India:
- No equivalent to the UK’s Export Control Act or EU regulations exists in Indian law requiring an assessment of a country’s compliance with IHL obligations in deciding whether to export defence equipment to such a country.
- Indian laws like the Foreign Trade Act (1992) and the Weapons of Mass Destruction and their Delivery Systems (Prohibition of Unlawful Activities) (WMDA) Act, 2005 allow the government to regulate arms exports under certain conditions including national security and international obligations.
- Currently India is not under an obligation to review the IHL compliance of the country to which India is exporting defence goods. Thus, there exists a legal gap.
Role of the Supreme Court:
- The Supreme Court has previously used international law to expand domestic law and to fill the vacuum created by the absence of domestic law on a subject (e.g., Vishakha vs. State of Rajasthan).
- The current situation should be addressed in the same manner rather than as a foreign policy issue.
International law:
Arms Trade Treaty:
- The Arms Trade Treaty (ATT) prohibits supplying arms if there is knowledge they may be used for war crimes.
- The treaty obligates states to assess whether the conventional arms they export would be used by the importing country to commit or facilitate a serious violation of IHL.
- India is not a signatory to the ATT, making it non-binding, though some provisions reflect customary international law.
Geneva conventions:
- Common Article 1 of the Geneva Conventions obligates states to ensure respect for IHL.
- Countries are under obligation not to supply weapons to a country ‘if there is an expectation, based on facts or knowledge of past patterns, that such weapons would be used to violate the Conventions’.
- This is binding on India as India is a party to the conventions.
Recommendations:
- India’s domestic laws (WMDA and FTA) should be amended to include explicit assessments of IHL compliance for importing countries.
- This would enhance India’s credibility as a responsible defence-exporting nation and align its actions with international obligations.
12. India to launch its first mission to Venus in 2028: Everything you need to know
Sub: Sci
Sec: Space sector
Context:
- The Union Cabinet approved India’s first mission to Venus which ISRO aims to launch in March 2028.
- This is the country’s second interplanetary mission after the Mars Orbiter Mission launched in 2013.
Overview of India’s Venus Mission (Shukrayaan):
- ISRO will be responsible for the development of spacecraft and its launch.
- It will be an orbiter missione., the spacecraft will be sent into an orbit around Venus, to study the planet from a distance.
- Objective: To explore the surface and sub-surface of Venus, its atmosphere and its interaction with the Sun.
- Optimal Launch Window: Earth and Venus align for the shortest path every 19 months. The mission is expected to be accomplished on the opportunity available during March 2028.
- Payload: Scientific payloads include a high-resolution Synthetic Aperture Radar, thermal cameras
- Trajectory: Similar to previous Indian space missions, the satellite will gain speed in Earth’s orbit, will get sling-shot towards Venus, and then get captured in its orbit.
- Travel Duration: Once launched, it will take about 140 days to reach Venus after exiting Earth’s orbit.
- Initial Orbit: Satellite will be placed in a highly elliptical orbit of 500 km x 60,000 km around Venus. This high orbit is unsuitable for conducting scientific experiments.
- Target Orbits: The goal is to lower the satellite to either a 300 x 300 km or 200 x 600 km orbit, based on payload requirements. This will be done using Aero-breaking.
Aero-Braking:
- Aerobraking is a technique used in space missions that involves using a planet’s atmosphere to slow down a spacecraft by creating drag, enabling manoeuvres such as orbit adjustments.
Why is it important to study Venus?
- Venus is often called Earth’s twin because it is similar in mass, density, and size. Therefore, studying Venus can provide insights into the evolution of Earth.
- Venus is thought to have had water at some point in its history but has now become a dry and dusty planet.
Differences between Earth and Venus:
- Venus has extremely high surface temperature of around 4620C, making it hotter than Mercury. Scientists think this is because of a runaway greenhouse effect.
- It is thought that the water present on the Venusian surface evaporated because of the proximity of the planet to the Sun. As water vapour is a greenhouse gas, it led to the planet trapping more heat and further evaporating water from its surface.
- These hot temperatures are the reason why no lander to Venus has survived for more than a couple of hours.
- The atmospheric pressure on Venus is much higher than on Earth. It is almost similar to the pressure felt underneath the oceans on Earth.
- 5% of the atmosphere of Venus is made up of carbon dioxide and there are sulphuric acid clouds on the planet.
- Venus rotates very slowly on its axis as compared to Earth. One rotation of Venus lasts around 243 Earth days.
Other Venus missions:
- There have been several missions to Venus in the past by US, Russia, Japan, and a collaborative mission of the European Space Agency (ESA) with Japan.
- Future missions:
- US missions DaVinci in 2029 and Veritas in 2031
- EnVision mission of ESA for 2030
