Pyrocumulonimbus clouds
GS 1: Geography: Wildfires
Why is it in the news?
- The intense wildfires currently wrenching in the United States and Canada are generating ‘Pyrocumulonimbus’ clouds, which can produce thunder and ignite additional fires.
About the news
- Formation Process:
- Pyrocumulonimbus clouds form under specific conditions, primarily driven by extremely intense wildfires or volcanic eruptions.
- These clouds are not a common outcome of every wildfire; rather, they emerge when the fire reaches extraordinarily high temperatures.
- For instance, during the Australian bushfires of 2019-2020, where temperatures soared above 800 degrees Celsius, pyrocumulonimbus clouds were created.
- The process begins with the intense heat from the fire warming the surrounding air, which then rises and carries water vapor, smoke, and ash upwards.
- Evolution into Pyrocumulonimbus Clouds:
- As this hot and buoyant air ascends, it expands and cools, causing the water vapor to condense on the ash particles and form a grey or brown cloud, known as a pyrocumulus cloud, or “fire cloud.”
- If sufficient water vapor is present and the upward air movement intensifies, the pyrocumulus cloud can evolve into a pyrocumulonimbus cloud. These clouds can reach heights of up to 50,000 feet and generate their own thunderstorm systems.
- Effects and Risks:
- Although pyrocumulonimbus clouds can produce lightning, they generally do not produce much rain, which can result in new fires being ignited many kilometres away from the original blaze.
- Additionally, these clouds can generate strong winds, potentially accelerating and complicating the spread of the wildfire.
- Increasing Frequency:
- The frequency of pyrocumulonimbus cloud events has been increasing in recent years. Before 2023, an average of 102 pyrocumulonimbus clouds were recorded globally each year, with approximately 50 of those in Canada.
- However, during the extreme wildfire season of the previous year, Canada alone saw 140 pyrocumulonimbus clouds. The reasons for this rise are not yet fully understood, as the study of these clouds is relatively new.
- Potential Contributing Factors:
- Scientists suggest that climate change may be contributing to the increase. Rising global temperatures are leading to more frequent and intense wildfires, which in turn could be increasing the likelihood of pyrocumulonimbus cloud formation.
Additional Information:
What is a Cloud?
- A cloud is an accumulation of tiny water droplets and ice crystals suspended in the Earth’s atmosphere, formed through the condensation of water vapor.
- Clouds, with their various types each with unique characteristics and altitudes, affect Earth’s climate by reflecting sunlight to cool the planet and trapping heat to warm it.
- Based on their altitude, clouds are classified into different types: high, middle, and low.
- High Clouds:
- Cirrus Clouds: High-level clouds above 20,000 feet, composed mainly of ice crystals. They appear thin, streaky, and white, occasionally showing colours at certain sunlight angles.
- Cirrostratus Clouds: Thin, sheet-like clouds at high altitudes that often cover the sky and create halos around the sun or moon.
- Cirrocumulus Clouds: High-altitude clouds appearing as small, white patches or ripples.
- Middle Clouds:
- Altostratus Clouds: Middle-level clouds between 6,500 and 20,000 feet, composed of liquid water droplets, ice crystals, or both, typically appearing as grey or blue-grey sheets covering the sky.
- Altocumulus Clouds: Mid-level clouds characterized by rounded masses or rolls.
- Low Clouds:
- Stratus: Appears as a thick, grey blanket hanging low in the sky, resembling fog, with a uniform layer. Warm stratus clouds indicate rain, while cold ones suggest snow.
- Cumulus Clouds: Fluffy, white clouds with a flat base and rounded top, formed by rising warm air currents and commonly seen on sunny days. They can develop into cumulonimbus clouds, which are linked to thunderstorms.
- Stratocumulus: Typically arranged in large, dark, rounded masses or globular formations, often appearing in groups, lines, or waves.
- Nimbostratus: Known as ‘rain clouds,’ they are dark, thick, and bring light to moderate precipitation.
- Vertical Clouds:
- Cumulonimbus Clouds: They are dense towering and vertical and their top acquires an ‘Anvil Shape’, extending from lower to higher altitudes, created through thermal convection or frontal lifting, often leading to thunderstorms and heavy rain.

RBI policy panel kept interest rates unchanged
GS 3: Economy: RBI’s MPC
Why is it in the news?
- The Reserve Bank of India’s (RBI) Monetary Policy Committee (MPC) has kept the Repo rate steady at 6.5% for the ninth consecutive time due to persistent food inflation, which remains a significant threat to retail inflation.
More about the news
- The MPC also maintained its monetary policy stance of ‘withdrawal of accommodation’ during its August 8 meeting which means banks are likely to keep interest rates unchanged, so borrowers will see their equated monthly instalments (EMIs) remain stable.
- The RBI has upheld its FY2025 GDP growth projection at 7.2% and retail inflation forecast at 4.5%, despite ongoing food inflation concerns, reflecting strong economic activity and improving demand.
- Headline inflation rose to 5.1% in June from 4.8% in May, with food inflation contributing significantly at 8.4%.
- The RBI’s goal under the flexible inflation targeting regime is to keep consumer price index (CPI) inflation within the 2-6% range and ideally bring it down to 4% on a durable basis.
- With the Repo rate unchanged, external benchmark lending rates (EBLR) linked to the repo rate will not increase, providing relief to borrowers.
- However, interest rates on loans linked to the marginal cost of fund-based lending rate (MCLR) might still rise, as some banks have yet to fully transmit past rate hikes. The deposit rates may also see a slight increase due to recent trends in credit and deposit growth.

Contentious amendments to the Waqf Act and its implications
GS 2: Polity and Governance: Waqf Act
Why is it in the news?
- On August 8, 2024, the Union government introduced a Bill in the Lok Sabha to amend the 1995 Waqf Act, aiming to reform the regulation of waqf properties in India.
- The proposed Unified Waqf Management, Empowerment, Efficiency, and Development Act, 2024, seeks to enhance the Centre’s control over waqf properties and introduces several contentious changes, including allowing non-Muslim members on Waqf Boards.
- Currently, Waqf Boards manage 8.7 lakh properties across 9.4 lakh acres in India, valued at approximately ₹1.2 lakh crore. Waqf properties, dedicated to religious and charitable purposes under Islamic law, cannot be sold or inherited once designated as waqf.
Key amendments proposed in the Waqf Act (Amendment), 2024:
- Reformation of Waqf Definition:
- The new Bill proposes changing the definition of ‘waqf’ to require that only property owners who have practiced Islam for at least five years can create waqf properties through formal deeds, thus eliminating the ‘waqf by use’ concept which recognized properties based on usage even without formal documentation.
- Revised Verification Procedures:
- Additionally, the Bill transfers the responsibility for surveying waqf properties from survey commissioners to district collectors or equivalent officers and introduces a centralised registration system.
- Under the new law, disputed properties cannot be recognized as waqf until the district collector submits a final report, which could undermine the authority of Waqf Boards and affect religious freedoms.
- The Bill also empowers the Centre to audit waqf properties at any time, with auditors appointed by the Comptroller and Auditor-General of India. It mandates annual audits by Waqf Boards and imposes penalties on mutawallis for failing to maintain proper accounts.
- The proposed law removes the finality of decisions made by waqf tribunals, allowing appeals to High Courts, which experts believe might impact the autonomy of waqf institutions.
- Reorganization of Waqf Boards:
- A particularly contentious aspect of the Bill is its proposal to permit non-Muslims to serve on the Central Waqf Council, State Waqf Boards, and waqf tribunals.
- Sections 9 and 14 of the Waqf Act, 1995 will be amended to alter the Waqf Board’s composition and functioning, incorporating women representatives and also includes appointing non-Muslim Members of Parliament to the Central Waqf Council and mandating the inclusion of non-Muslim members on State Waqf Boards.
- Following its introduction, the Bill was referred to a joint parliamentary panel for further scrutiny. Further, the Union government also reported that approximately 120 petitions challenging various provisions of the 1995 Act are pending in courts across the country.
Criticisms of the Waqf Act, 1995 Amendment:
- Critics argue that altering the composition of Waqf board could compromise the autonomy of Muslim religious institutions and interfere with religious self-governance.
- Experts expressed concerns about ensuring that reforms improve efficiency without infringing on religious freedoms and questioned whether non-Hindus would be allowed on Hindu temple boards in various states.
Additional Information:
Understanding Waqf: Definition and Purpose
- About:
- Under the Waqf Act of 1954, Waqf is the permanent dedication of movable or immovable property for religious, pious, or charitable as recognised by Muslim law.
- A Waqf can be established via a deed or instrument, with its proceeds generally supporting educational institutions, graveyards, mosques, and shelters.
- Waqfs can be either public, serving charitable ends, or private, benefiting the property owner’s direct descendants.
- Once a property is designated as a Waqf, it becomes non-transferable and is detained perpetually as a charitable act toward God, essentially transferring ownership to God.
- Regulation:
- Waqfs in India are regulated by the Waqf Act, 1995.
- Management of Waqf:
- To create a Waqf, one must be of sound mind and hold valid property ownership, and while the Waqif (creator of a Waqf) does not need to be Muslim, they must believe in Islamic principles.
- The Waqf is managed by a mutawalli, who supervises its operations.
- A survey commissioner lists all properties declared as Waqf by conducting local investigations, summoning witnesses, and requisitioning public documents.
- Unlike trusts under the Indian Trusts Act, 1882, which can serve a variety of purposes and be dissolved by the board, Waqfs are exclusively for religious and charitable purposes and are meant to be perpetual.
What is Waqf Act, 1955?
- The Waqf Act was initially passed by Parliament in 1954, which got repealed, and replaced by a new Waqf Act in 1995, which granted greater powers to Waqf Boards.
- The Waqf Act, 1955 established the Central Waqf Council and State Waqf Boards to enhance the administration of waqf properties, distributing powers between Chief Executive Officers and Waqf Boards.
- In 2013, the Act was further amended to grant the Waqf Board extensive powers to designate property as ‘Waqf Property.’
Union govt. amends CAA guidelines on documents to prove foreign origin
GS 2: Polity and Governance: CAA
About the news
- The Union Home Ministry has revised the guidelines for the Citizenship (Amendment) Act (CAA), 2019, particularly concerning the documentation required to prove foreign origin.
- The updated rules now allow the use of any document issued by the State or Union government or quasi-judicial authorities in India, and include a new “etc.” clause, which gives officials discretion in handling cases with incomplete documents.
- Additionally, the amended rules permit local priests or “locally reputed community institutions” to issue certificates verifying an applicant’s faith.
- The CAA aims to grant citizenship to six non-Muslim communities (Hindus, Sikhs, Buddhists, Jains, Parsis and Christians) from the three countries (Afghanistan, Bangladesh, or Pakistan) if they entered India before December 31, 2014.
- Union government officials have been directed to interpret the CAA as a facilitative law, ensuring its spirit is considered in application processing.
- The amendment follows the 2019 change to the Citizenship Act, 1955, which facilitated citizenship through registration and naturalisation for undocumented migrants from these six non-Muslim communities.
Additional Information:
Issues Surrounding the Citizenship Amendment Act (CAA):
- Conflict with Secular Principles: The CAA is viewed as conflicting with India’s secular Constitution by favouring certain religious groups, thus challenging the principle of equal treatment before the law regardless of religion.
- Concerns of Illegal Migration: Indigenous communities in the northeast fear the CAA could lead to a loss of political, cultural, and land rights, along with increased migration from Bangladesh.
- Against the Right to Equality: Critics argue that the CAA violates Article 14 of the Indian Constitution by granting citizenship based on religion and prohibits discrimination based on religion.
- Conflict with Assam Accord: The CAA is seen as conflicting with the 1985 Assam Accord by extending the cut-off date for citizenship to December 31, 2014, whereas the Accord restricts citizenship to migrants arriving before March 25, 1971, thus altering the agreed timeline could lead to legal and political complications.

Why Himalayan towns need a different kind of development?
GS 1: Geography: Development in Himalayan Range
Why is it in the news?
- The Indian Himalayan Range (IHR), covering 11 States and two Union Territories, has seen a substantial urban growth rate of over 40% from 2011 to 2021.
- Towns in this region, including Srinagar, Guwahati, Shillong, and Shimla, face significant challenges in managing civic issues such as sanitation, waste management, and water supply.
About Indian Himalayan Region (IHR): The Himalayas are young fold mountains, tectonically active and formed by the massive collision between the Eurasian plate and the northward-drifting Indian plate approximately 50 million years ago.It covers 18% of India’s total geographical area and encompasses 50% of the country’s forest cover and biodiversity. Importance of IHR: Known as India’s “water tower,” the region is the source of major rivers like the Ganges, Yamuna, and Brahmaputra, and their tributaries, supporting the livelihoods of approximately 1.4 billion people who rely on these glacial-fed rivers for their survival.The region is crucial for ecological balance and biodiversity, home to diverse flora and fauna, including many endemic and endangered species, and features national parks and biosphere reserves like the Valley of Flowers and Nanda Devi.The Himalayas regulate the climate by blocking frigid, dry arctic winds from moving south and acting as a barrier to monsoon winds, directing rainfall to the southern slopes.Additionally, its high-altitude lakes, mountain peaks, and sacred sites offer significant potential for eco-tourism, adventure tourism, and religious tourism, such as the destinations of Amarnath and Badrinath etc. |
More about the news
- Planning institutions often rely on models adapted from the plains, which are unsuitable for the unique conditions of the Himalayas. Additionally, many areas are severely understaffed, with some regions having as few as 15 executive officers for over 40 urban local bodies.
- Urban expansion into rural peripheries, as seen in cities like Srinagar and Guwahati, has led to the encroachment on open spaces, forests, and water bodies.
- For instance, Srinagar has experienced a 75.58% increase in built-up areas and a 25% decrease in water bodies between 2000 and 2020. Furthermore, nearly 90% of liquid waste in these cities is discharged into water bodies without treatment.
- The IHR’s urbanisation is compounded by high-intensity tourism, unsustainable infrastructure, and climatic variations, resulting in water scarcity, deforestation, land degradation, and pollution.
- Tourism, with an anticipated average annual growth rate of 7.9% from 2013 to 2023, often leads to the replacement of eco-friendly infrastructure with poorly designed constructions and inadequate waste management systems, damaging biodiversity and ecosystem services.
- To address these issues, urban planning in IHR cities should involve detailed geological and hydrological mapping, local community participation, and a focus on climate resilience. Consultant-driven planning processes should be replaced by locally tailored, eco-centric designs.
- Moreover, given that IHR cities struggle to generate capital for infrastructure, the Finance Commission should include a dedicated chapter on urban financing for the region, increasing intergovernmental transfers from 0.5% to at least 1% of GDP.
- Hence, sustainable urban development in the IHR requires robust, participatory planning processes that prioritize environmental and community needs.
Additional Information:
Measures to be taken to Promote Sustainable Development in the IHR:
- Climate-Resilient Infrastructure: Adopt resilient building codes, invest in green infrastructure, and enforce a construction ban in disaster-prone areas as recommended by the Mishra Committee, 1976.
- Integrated Development: Establish a “Himalayan Authority” to coordinate comprehensive development, ensure synergy among states, provide strategic guidance, and monitor the fulfilment of SDGs.
- Enhancing Water Security: Revive deteriorated springs using best practices like Dhara Vikas in Sikkim, promote rainwater harvesting systems in all areas, and follow the NGRBA’s comprehensive approach to clean and rejuvenate the Ganga River.
- Promoting Sustainable Agriculture: Promote organic farming to maintain soil health and integrate trees and shrubs into farming systems for enhanced biodiversity and crop yields.
- Sikkim’s status as India’s first fully organic state highlights these practices.
- Advancing Eco-Friendly Tourism:
- Regulate tourist numbers with carrying capacity assessments, develop eco-tourism initiatives for local benefits, promote biodegradable materials, and reduce plastic waste.
- Implement business plans for “Smart Mountain Tourism Destinations” similar to Smart Cities and introduce a ‘Green Cess’ based on eco-certification.
- Enhancing Education and Awareness: Integrate basic knowledge of the Himalayas’ geology and ecology into school curricula to foster a deeper connection and awareness among students which will encourage stricter adherence to environmental protection laws.
- Capacity building: Research needs to be strengthened is in blending traditional knowledge on resource use and management with modern scientific approaches.
Supreme Court Rulings on Environmental Conservation in the IHR:Recognition of the Right against Climate Change: In MK Ranjitsinh vs. Union of India case (2024), Supreme Court recognized the right to be free from the adverse effects of climate change under Articles 14 and 21 of the Indian Constitution.Guidelines for Managing Carrying Capacity in Himalayan States: In the Ashok Kumar Raghav vs Union of India case (2023), the Supreme Court directed the central government and the petitioner to propose a framework for determining the carrying capacity of Himalayan states and towns to ensure sustainable development.Embracing an Eco centric Perspective on the Environment: In State of Telangana and Others vs Mohd. Abdul Qasim case, the Supreme Court had said that the need of the hour is to adopt an eco-centric view of the environment, where nature is at the core.

Antarctica’s deep-winter heatwave
GS 3: Environment and Biodiversity: Antarctica’s heatwave
Why is it in the news?
- For the second time in two years, Antarctica is experiencing a record-breaking heatwave during its winter season.
More about the news
- Since mid-July, ground temperatures have averaged 10 degrees Celsius higher than normal, with some days reaching up to 28 degrees above the usual levels.
- In East Antarctica, which comprises two-thirds of the continent, temperatures are currently between minus 25 degrees and minus 30 degrees Celsius, whereas typical deep-winter temperatures range from minus 50 degrees to minus 60 degrees Celsius.
- These elevated temperatures, though still extremely cold by most standards, are alarmingly high for the continent.
- Scientists attribute the heatwave to the weakening of the polar vortex—a band of cold air and low-pressure systems that usually contains cold air around the poles. This year, large-scale atmospheric waves disturbed the vortex, allowing warmer air to enter Antarctica.
- According to the British Antarctic Survey, such a weakened vortex is a rare phenomenon, occurring only once every two decades on average. Additional contributing factors include a reduction in Antarctic Sea ice, which was at its second-lowest extent in June compared to previous years.
- Sea ice, which reflects sunlight and keeps the air cool, has been diminished, leading to warmer winter conditions.
- Global warming has also significantly impacted Antarctica, with the continent warming at a rate of 0.22 to 0.32 degrees Celsius per decade, nearly twice the global average. This rapid warming contributes to accelerated ice loss, with Antarctica losing 280% more ice mass in the 2000s and 2010s compared to the 1980s and 1990s.
- The 2022 heatwave, which saw temperatures 39 degrees Celsius above normal, caused a significant portion of the ice sheet to collapse. The Antarctic Ice Sheet, which holds more than 60% of the world’s freshwater, has the potential to raise global sea levels significantly. Even a small rise in sea level could displace millions of people living near the coast.
- Furthermore, the melting ice is affecting global ocean circulation, which regulates climate by transporting heat, carbon, nutrients, and freshwater. A 2023 study revealed that melting ice reduces the salinity and density of surface waters, slowing down ocean circulation.
- This disruption will lead to oceans absorbing less heat and CO2, exacerbating global warming and increasing the frequency and severity of extreme weather events such as floods and droughts.
