From snowstorms to heatwaves: India’s alarming climate shift in 2025

By Dr. Gurinder Kaur* 
Climate change is no longer a future concern—it is visibly affecting every country today. Since the beginning of 2025, its effects on India have become starkly evident. These include unseasonal snowfall in hill states, the early onset of heatwaves in southern regions, a shortening spring season, and unusually early and heavy rainfall, among other phenomena.
In the north-western and north-eastern parts of the country, winter and snowfall typically occur during January and February. However, this year, like in many other parts of the world, January turned out to be the second warmest on record, and February the warmest ever. Due to above-average temperatures, snowfall did not occur in many hill states. In some areas, rainfall was 60 to 99 per cent below normal. Surprisingly, on the last day of February, all the hill states received heavy snowfall. In March—when these regions typically enjoy the colourful bloom of spring—they remained covered in a white blanket of snow. This marked the first major climate event of 2025.
One severe snowstorm in Chamoli district of Uttarakhand struck with such intensity that it swept away 55 labourers of the Border Roads Organisation along with the iron containers they were living in. Tragically, 8 labourers lost their lives, and the remaining 47 were rescued after a strenuous operation.
The second major climate change event was recorded in southern India, which usually experiences mild weather in January and February. This year, however, the first heatwave was reported as early as February 25 in the Konkan region on the west coast. According to the India Meteorological Department (IMD), a heatwave is declared when the temperature is 5°C above average, or when it exceeds 30°C in hilly regions, 37°C in coastal areas, or 40°C in the plains. By the second week of March, temperatures in parts of Central Maharashtra, Saurashtra, Kutch, Vidarbha, Odisha, Telangana, and Andhra Pradesh had crossed 40°C, clearly signalling the intensifying grip of climate change.
Due to these extreme cold and hot weather conditions, the spring season has vanished from some regions—marking the third significant shift in India's climate. In addition, hilly states experienced unusually heavy rainfall in April, typical of the monsoon season in June and July. This led to several incidents of landslides in Jammu & Kashmir and Sikkim, marking the fourth major climatic event of the year.
These changing climate patterns have also led to a rise in the frequency and intensity of natural disasters. In April, strong winds destroyed hundreds of acres of ripe wheat crops in Punjab and Haryana. In Bihar and Uttar Pradesh, lightning strikes claimed the lives of more than 100 people.
On April 1st, the IMD issued a weather forecast for April to June, predicting above-average temperatures in 15 states: Punjab, Haryana, Uttar Pradesh, Bihar, Jharkhand, West Bengal, Odisha, Telangana, Andhra Pradesh, Chhattisgarh, northern Karnataka, Maharashtra, Gujarat, Rajasthan, and Madhya Pradesh. These regions typically experience heatwaves lasting 4 to 7 days, but this year they could persist for 10 to 11 days. In the north-western and north-eastern hilly regions, as well as in Kerala and Karnataka, heavy rainfall, landslides, and mudslides are also anticipated.
All the above-mentioned events and forecasts are closely linked to climate change. While heatwaves and heavy rainfall are not new to any country, their earlier onset, increased frequency, and greater severity are direct consequences of climate change. The Intergovernmental Panel on Climate Change (IPCC) clearly outlined the major risks India could face from climate-induced disasters in its Fifth (2014) and Sixth (2021–2022) Assessment Reports. These reports emphasized that India, compared to many other countries, would be more adversely affected.
One reason why India is particularly vulnerable to climate change is its geographical location combined with its model of economic development. The Himalayas, to the north, are the highest and youngest mountain range in the world, while India is flanked by the sea on three sides in the south. Due to rising global average temperatures, Himalayan glaciers are melting rapidly, leading to a significant increase in the size of glacial lakes. Between 2011 and 2024, the size of 67 glacial lakes in India—mainly in Uttarakhand, Ladakh, Sikkim, Arunachal Pradesh, and Himachal Pradesh—increased by 40 per cent. These lakes now pose a growing risk of bursting.
The potential consequences were demonstrated in 2023, when the Lhonak glacial lake in Sikkim burst. Over 200 people died, around 80,000 were severely affected, and a dam along with all the bridges over the Teesta River were washed away. Such glacial bursts and melting can lead to devastating floods in the plains, which in turn can destroy crops and trigger food insecurity.
In 2013, a cloudburst in Kedarnath (Uttarakhand) caused catastrophic flooding, killing thousands of residents and pilgrims, and leaving hundreds of thousands stranded. In mountainous areas, climate change has brought intense rainfall that triggers landslides and mudslides, disrupting life and infrastructure. While some landslides are natural, large-scale landslides are largely a result of the economic development model being pursued. To boost tourism, governments have promoted infrastructure such as four-lane highways, ropeways, and helipads, often ignoring environmental regulations. This has led to deforestation and excavation of hills, increasing the likelihood of landslides, land subsidence, and cloudbursts.
In southern India, surrounded on three sides by the sea, sea-related disasters are becoming more frequent and intense. Since March 2023, sea surface temperatures globally have remained above average. This has contributed to the early arrival of heatwaves and a rise in their frequency along coastal regions. Rising sea levels, more frequent cyclones, and marine heatwaves are all tied to warming seas. Nearly 40 per cent of India’s population lives in coastal areas, whose homes and agricultural lands are at risk of submergence. This will create enormous challenges for rehabilitation and disaster management.
Kerala and Karnataka also lie in the ecologically sensitive Western Ghats. In 2011, the Gadgil Committee, constituted by the central government, recommended that 87.5 per cent of the Western Ghats be declared ecologically sensitive, proposing 52 restrictions on development. However, both central and state governments rejected the report. Since then, unregulated development has continued, and ordinary people bear the consequences through increasingly frequent natural disasters. The 2024 tragedy in Wayanad, Kerala, stands as stark evidence.
Therefore, the central and state governments must develop region-specific plans based on geographical realities. In hilly regions, road widths should match the local carrying capacity. In the south, especially in the Western Ghats, development should follow the Gadgil Committee's recommendations. Additionally, India must take serious steps to raise forest cover to 33 per cent.

A comrade in culture and controversy: Yao Wenyuan’s revolutionary legacy

By Harsh Thakor*  This year marks two important anniversaries in Chinese revolutionary history—the 20th death anniversary of Yao Wenyuan, and the 50th anniversary of his seminal essay "On the Social Basis of the Lin Biao Anti-Party Clique". These milestones invite reflection on the man whose pen ignited the first sparks of the Great Proletarian Cultural Revolution and whose sharp ideological interventions left an indelible imprint on the political and cultural landscape of socialist China.

What's behind Donald Trump's 'narco-state' accusation against Venezuela

By Manolo De Los Santos  The US government has revived its campaign to label Venezuela a "narco-state", accusing its top leadership of drug trafficking and slapping hefty bounties on their heads for capture. This campaign, which only momentarily took a backseat, is a strategic fabrication, not a factual assessment. This accusation, particularly amplified under the Trump Administration, is a calculated smokescreen to justify a long-standing agenda: the overthrow of the Venezuelan government and the seizure of its vast oil and mineral resources. A closer examination of the facts reveals a country that has actively fought drug trafficking on its own terms and a US government with a clear and consistent history of destabilizing independent countries in Latin America.

1857 War of Independence... when Hindu-Muslim separatism, hatred wasn't an issue

"The Sepoy Revolt at Meerut", Illustrated London News, 1857  By Shamsul Islam* Large sections of Hindus, Muslims and Sikhs unitedly challenged the greatest imperialist power, Britain, during India’s First War of Independence which began on May 10, 1857; the day being Sunday. This extraordinary unity, naturally, unnerved the firangees and made them realize that if their rule was to continue in India, it could happen only when Hindus and Muslims, the largest two religious communities were divided on communal lines.

Two more "aadhaar-linked" Jharkhand deaths: 17 die of starvation since Sept 2017

Kaleshwar's sons Santosh and Mantosh Counterview Desk A fact-finding team of the Right to Feed Campaign, pointing towards the death of two more persons due to starvation in Jharkhand, has said that this has happened because of the absence of aadhaar, leading to “persistent lack of food at home and unavailability of any means of earning.” It has disputed the state government claims that these deaths are due to reasons other than starvation, adding, the authorities have “done nothing” to reduce the alarming state of food insecurity in the state.

New RTI draft rules inspired by citizen-unfriendly, overtly bureaucratic approach

By Venkatesh Nayak* The Department of Personnel and Training , Government of India has invited comments on a new set of Draft Rules (available in English only) to implement The Right to Information Act, 2005 . The RTI Rules were last amended in 2012 after a long period of consultation with various stakeholders. The Government’s move to put the draft RTI Rules out for people’s comments and suggestions for change is a welcome continuation of the tradition of public consultation. Positive aspects of the Draft RTI Rules While 60-65% of the Draft RTI Rules repeat the content of the 2012 RTI Rules, some new aspects deserve appreciation as they clarify the manner of implementation of key provisions of the RTI Act. These are: Provisions for dealing with non-compliance of the orders and directives of the Central Information Commission (CIC) by public authorities- this was missing in the 2012 RTI Rules. Non-compliance is increasingly becoming a major problem- two of my non-compliance cases are...

Epic war against caste system is constitutional responsibility of elected government

Edited by well-known Gujarat Dalit rights leader Martin Macwan, the book, “Bhed-Bharat: An Account of Injustice and Atrocities on Dalits and Adivasis (2014-18)” (available in English and Gujarati*) is a selection of news articles on Dalits and Adivasis (2014-2018) published by Dalit Shakti Prakashan, Ahmedabad. Preface to the book, in which Macwan seeks to answer key questions on why the book is needed today: *** The thought of compiling a book on atrocities on Dalits and thus present an overall Indian picture had occurred to me a long time ago. Absence of such a comprehensive picture is a major reason for a weak social and political consciousness among Dalits as well as non-Dalits. But gradually the idea took a different form. I found that lay readers don’t understand numbers and don’t like to read well-researched articles. The best way to reach out to them was storytelling. As I started writing in Gujarati and sharing the idea of the book with my friends, it occurred to me that while...

Ground reality: Israel would a remain Jewish state, attempt to overthrow it will be futile

By NS Venkataraman*  Now that truce has been arrived at between Israel and Hamas for a period of four days and with release of a few hostages from both sides, there is hope that truce would be further extended and the intensity of war would become significantly less. This likely “truce period” gives an opportunity for the sworn supporters and bitter opponents of Hamas as well as Israel and the observers around the world to introspect on the happenings and whether this war could have been avoided. There is prolonged debate for the last several decades as to whom the present region that has been provided to Jews after the World War II belong. View of some people is that Jews have been occupants earlier and therefore, the region should belong to Jews only. However, Christians and those belonging to Islam have also lived in this regions for long period. While Christians make no claim, the dispute is between Jews and those who claim themselves to be Palestinians. In any case...
