From UPSC perspective, the following things are important :
Prelims level: Leap Second, Leap Year, UTC, TAI
Mains level: NA
Why in the news?
- A recent publication in the science journal Nature highlights how climate change-induced melting of glaciers and ice sheets is altering the Earth’s rotation, potentially disrupting our timekeeping systems.
- Leap seconds were added almost every year between 1972 and 1999 to adjust for Earth’s slowing rotation. But there have only been four added in the last 23 years, and the last time a leap second was added was in 2016.
What is a Leap Second?
- A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to synchronize atomic time with astronomical time, particularly with the Earth’s rotation.
- The purpose of adding or subtracting a leap second is to keep International Atomic Time (IAT) (which is extremely precise) in close alignment with astronomical time, which is based on the Earth’s rotation and is subject to slight variations.
There are two types of leap seconds:
- Positive Leap Second:
- A positive leap second is added to UTC when the Earth’s rotation slows down slightly, causing the length of a day to exceed 86,400 seconds.
- This type of leap second is necessary to bring UTC back into alignment with the Earth’s rotational time.
- Positive leap seconds are rare and occur less frequently than negative leap seconds.
- Negative Leap Second:
- A negative leap second, also known as a deletion or removal of a second, occurs when the Earth’s rotation speeds up slightly, causing the length of a day to be less than 86,400 seconds.
- Negative leap seconds are extremely rare and have only been proposed but never implemented. They are considered hypothetical and have not yet been needed to adjust UTC.
- The concept of negative leap seconds is controversial and requires international agreement and coordination among timekeeping organizations.
International Atomic Time (TAI)
- TAI is a high-precision time scale based on the weighted average of atomic clocks (usually involving caesium or rubidium atoms) from various laboratories around the world.
- It is one of the primary time scales used for scientific and technical purposes, providing a continuous and uniform time reference that is independent of the Earth’s rotation.
- TAI is maintained since 1958 by the International Bureau of Weights and Measures (BIPM) in Paris, France.
- Unlike UTC, which is adjusted periodically to account for the Earth’s irregular rotation, TAI is a continuous time scale that does not include any corrections for Earth’s rotation.
|

How Climate Change causes Negative Leap Second?
- Glacial Melting: Accelerating melt rates in Greenland and Antarctica are redistributing weight across the planet, causing a slight deceleration in the Earth’s rotation.
- Historical Context: Timekeepers have periodically added leap seconds to clocks worldwide to account for the Earth spinning faster than usual, with 27 instances recorded since the 1970s.
- Planned Adjustment: The proposed “negative leap second” adjustment, scheduled for 2026, may be postponed until 2029 or later due to the recent deceleration in the Earth’s rotation.Top of Form
Practice MCQ:
What is a Leap Second?
(a) It is a periodic adjustment added to International Atomic Time (TAI) to compensate for irregularities in Earth’s rotation.
(b) It is an extra second added to Coordinated Universal Time (UTC) to synchronize atomic time with astronomical time.
(c) It is the time lag measured by the atomic clocks in Outer Space-Time conditions.
(d) It is a term used to describe the synchronization of atomic clocks with the oscillations of subatomic particles. |

Prelims level: Kallakkadal, Tsunami
Mains level: NA

Why in the news?
- Coastal areas of Kerala, including Alappuzha, Kollam, and Thiruvananthapuram districts, are grappling with flooding caused by high sea waves, known as swell waves or Kallakkadal in Malayalam.
- The recent swell surge occurred following a low-pressure system originating in the South Atlantic Ocean, leading to the formation of waves reaching heights of up to 11 meters.
What is Kallakkadal?
- Origin and Meaning:
- Kallakkadal refers to coastal flooding during the (April-May) pre-monsoon season.
- It is caused by ocean swell waves on the southwest coast of India.
- The term “Kallakkadal” originates from Malayalam, combining “Kallan” (thief) and “Kadal” (sea), denoting the sea’s unexpected intrusion akin to a thief.
- In 2012, the term was formally approved by the UNESCO (United Nations Educational, Scientific and Cultural Organization).
- Causes:
- These waves stem from distant storms, such as hurricanes, generating significant energy transfer from the atmosphere to the water.
- Kallakkadal typically results from strong winds in the southern Indian Ocean, generating ocean swells that travel northward towards the Kerala coast.
Features of Kallakkadal
- This phenomenon occurs mostly during pre-monsoon season and sometimes during post monsoon.
- It continues for a few days.
- It inundates the low lying coasts.
- Initially sea recedes before the surge.
- During high tide the run-up, water level can reach as much as 3–4 m above Maximum Water Level (MWL).

From UPSC perspective, the following things are important :
Prelims level: Zero FIR vs ordinary FIR
Mains level: NA

Why in the news?
- The Hyderabad Police have initiated a zero FIR case against former minister for alleged derogatory remarks against Telangana CM.
First Information Report (FIR)
- An FIR is a written document prepared by the police upon receiving information about a cognisable offence.
- It is when an officer can arrest a suspect without a court’s warrant if/she has “reason to believe” that the person committed the offence and arrest is necessary based on certain factors.
- It serves as the first step towards initiating the investigation process and subsequent police actions.
- Section 154(1) of the Criminal Procedure Code (CrPC) empowers the police to register an FIR for cognizable offences.
- Section 166A of the Indian Penal Code (IPC) provides punishment for public servants failing to record information related to a cognizable offence, with imprisonment of up to two years and a fine.
|
What is Zero FIR?
- Provision and Purpose: Zero FIR allows any police station to register an FIR for a cognisable offence without assigning a regular FIR number initially.
- No diary: Whereas FIRs have serial numbers assigned to them, zero FIRs are assigned the number ‘0’. Hence the name.
Features of a Zero FIR:
- Swift Action: The relevant police station subsequently registers a fresh FIR and commences the investigation.
- Focus on Victims: It is designed to expedite complaint lodging, particularly for serious crimes involving women and children, without the need to approach multiple police stations.
- Preserving Evidence: Early registration helps prevent the loss or tampering of crucial evidence and witnesses.
- Transferred Jurisdiction: The Zero FIR is later transferred to the relevant police station where the offence occurred or where the investigation should be conducted.
How does it work?
- After a police station registers a zero FIR, it has to transfer the complaint to a police station that has the jurisdiction to investigate the alleged offence.
- Once a zero FIR is transferred, the police station with the appropriate jurisdiction assigns it a serial number, thereby converting it into a regular FIR.
Legal Provisions for Zero FIR
The provision of Zero FIR finds support in various judgments and recommendations:
- Satvinder Kaur vs. State (1999): The Delhi High Court held that a woman has the right to lodge her complaint from any place other than where the incident occurred.
- Justice Verma Committee (2012): The introduction of Zero FIR was based on the recommendation of the Justice Verma Committee, which was formed in response to the 2012 Nirbhaya gangrape case.

Prelims level: Vaikom Satyagraha and the people associated
Mains level: NA

Why in the news?
This year April 1st marks 100 years of the Vaikom Satyagraha, in Kottayam, Kerala.
About Vaikom Satyagraha
- Vaikom was the epicentre of the Vaikom Satyagraha, which began in 1924.
- This movement aimed to challenge the ban imposed on marginalized communities from entering the vicinity of the Vaikom Mahadevar Temple in the princely state of Travancore.
- It sparked similar temple entry movements across India, advocating for the rights of untouchables and backward castes.
- It introduced nonviolent public protest as a method of resistance in Kerala.
A Precursor to the Vaikom Satyagraha
- Social and Political Developments
- Backdrop of Social Injustice: Travancore, characterized by feudal and caste-based governance, imposed stringent restrictions on lower castes, denying them entry to temples and public spaces.
- Emergence of Social Consciousness: By the late 19th century, progressive reforms and missionary activities led to increased awareness and education among lower castes, particularly the Ezhavas.
- Rise of Educated Elite: Educated individuals from diverse backgrounds, including lower castes, began to challenge social norms and demand equality in opportunities and rights.
- Beginning of Agitation
- Advocacy for Change: Ezhava leader T K Madhavan spearheaded efforts to challenge temple entry restrictions, advocating for direct action to confront discriminatory practices.
- Influence of Gandhi’s Ideals: Inspired by Gandhi’s principles of non-cooperation, Madhavan sought support from the Indian National Congress (INC) to mobilize a mass movement against untouchability.
Actual Course of Events
- Agitation
- Leaders such as T.K. Madhavan, K.P. Kesava Menon, and George Joseph spearheaded the agitation.
- Despite facing resistance and arrests by the police, the Satyagrahis persisted in their protest for over a year, resulting in numerous arrests and jails.
- Notable figures like Mahatma Gandhi, Chattampi Swamikal, and Sree Narayana Guru extended their support to the movement, which gained nationwide recognition.
- The involvement of women and support from various regions, including Punjab, highlighted the widespread impact of the Satyagraha.
- Suspension:
- Initially suspended in April 1924 at Gandhi’s suggestion, the movement resumed when attempts to resolve the issue with caste Hindu leaders failed.
- The absence of leaders like T.K. Madhavan and K.P. Kesava Menon, who were arrested, posed challenges to the movement.
- V. Ramaswamy Naicker (Periyar) lent support from Tamil Nadu before also being arrested.
- The resolution for the right to temple entry faced resistance in the Assembly, thwarted by traditionalist support and government pressure.
- Aftermath
- On October 1, 1924, a procession of Savarnas (forward castes) submitted a petition to the Regent Maharani Sethu Lakshmi Bai of Travancore, signed by around 25,000 individuals, urging for the temple’s open entry.
- Gandhi’s meeting with the Regent Maharani and the procession led by Mannath Padmanabhan Nair underscored the growing support for the cause.
- Eventually, on November 23, 1925, all temple gates were opened to Hindus except the eastern gate, marking a significant victory.
- The Vaikom Satyagraha laid the groundwork for the temple entry proclamation of Kerala in 1936 and inspired similar movements’ nationwide, promoting social justice and equality.

From UPSC perspective, the following things are important :
Prelims level: H5N1 Bird Flu
Mains level: NA

Why in the news?
- Since 2020, the highly pathogenic H5N1 bird flu has been spreading globally, posing a significant threat to both birds and mammals.
H5N1 Bird Flu: Details
- H5N1 originated from a virus outbreak on a goose farm in China in 1996 and has since evolved into a highly pathogenic strain.
- The virus quickly spread from Europe to Africa, Asia, North America, and South America, and most recently, it reached mainland Antarctica.
- H5N1 is a subtype of the influenza A virus that causes severe respiratory disease in birds, known as avian influenza or “bird flu”.
- Influenza A viruses are classified by subtypes based on the properties of their surface proteins, with H5N1 being one subtype.
How widespread is it?
- The virus has affected birds in over 80 countries, resulting in mass culling of poultry and wild birds.
- Furthermore, it has now begun infecting mammals, including seals, sea lions, and marine mammals.
- While humans rarely contract bird flu, those at risk are typically individuals who have extensive contact with infected birds at poultry farms.
- Bird flu first broke out in Maharashtra in 2006.
- The H5N1 virus led to the culling of millions of poultry so as to contain the virus. But it has resurfaced from time to time.
Impact on Animals
- Bird Species Affected: Numerous bird species, including Great Skuas and Barnacle Geese, have experienced significant mortality rates due to H5N1.
- Endangered Species Threatened: Endangered birds like the California condors have been severely affected, with a notable percentage of the population succumbing to the virus.
- Mammalian Casualties: H5N1 has crossed species barriers, infecting mammals such as foxes, pumas, skunks, and marine mammals like sea lions and dolphins.
- Devastating Consequences: Mass mortalities of marine mammals, particularly elephant seals, have been reported, raising concerns about the long-term ecological impact.
Factors behind Spread
- Climate Change: Some scientists attribute the large-scale spread of bird flu to climate change, which alters bird behavior and facilitates the transmission of the virus.
- Warmer Seas: Warmer sea temperatures have weakened marine mammal populations, making them more susceptible to disease outbreaks.
