A world on fire and choked for breath: The twin crises of climate change and air pollution

By Vikas Meshram

The world is heating at an alarming pace. Climate change, compounded by rising levels of air pollution, has brought humanity to the brink of a crisis unlike anything witnessed before. Weather cycles once predictable are now dangerously disrupted, while storms, floods, and fires strike with a frequency and ferocity that leave little room for recovery. The Earth, once a secure home for life, is turning into a place of uncertainty and fear.

Events that were once so rare as to be remembered for centuries are now disturbingly routine. Typhoon Wefa recently swept through southern China with such force that people were lifted into the air as they struggled to walk. In Uttarakhand, a cloudburst triggered catastrophic flooding that tore apart mountains and buried villages. In Russia’s far east, the Kroshennikov volcano erupted after six centuries, sending ash plumes four kilometers into the sky. These are not isolated accidents of nature but signs of a frightening new normal: climate change has turned the extraordinary into the ordinary.

Scientists describe this as a climate oxymoron—a paradoxical world where opposites coexist. Severe droughts grip one region even as catastrophic floods submerge another. Wildfires rage while glaciers melt at record speed. Hurricanes strike with triple the frequency recorded a century ago. Last April, torrential rains in the Mississippi Valley were so extreme that they were expected only once in 500 years. We now live in an age where disasters that once defined eras instead define seasons.

The science is clear and unsettling. A hotter atmosphere holds more moisture, accelerating the water cycle. When it rains, it pours with destructive intensity; when it dries, it scorches with merciless drought. Earth has already warmed 1.5°C above pre-industrial levels, and at the current pace, we may breach 2°C by 2030. Beyond that threshold lies uncharted territory with irreversible consequences for both humanity and nature.

Compounding this emergency is an insidious, less visible killer: air pollution. It does not grab headlines like a flood or hurricane, but its toll is relentless. It seeps into the lungs of millions, contaminates soils and waters, and destabilizes ecosystems. India today stands at the epicenter. Delhi, Mumbai, Kolkata, Bengaluru, and Chennai consistently rank among the world’s most polluted cities. Industrial smoke heavy with sulfur and nitrogen compounds hangs over skylines. Construction dust fills the air, while open burning of waste releases deadly toxins from plastics and rubber. Congested roads belch a poisonous cocktail of carbon monoxide and nitrogen oxides every day.

The human cost is staggering. Respiratory illnesses like asthma, bronchitis, and lung cancer are rising sharply, especially among children and the elderly. Long-term exposure increases the risk of heart disease and stroke. Acid rain corrodes soils, poisons rivers, and threatens entire ecosystems. Even the economy bears the scars—soaring healthcare costs, declining worker productivity, and a diminishing quality of urban life. In some cities, festivals are celebrated indoors and citizens advised to stay home, their daily rhythm choked off by toxic air.

Yet all is not lost. The solutions are known, if not yet implemented with urgency. Industries can install filters and scrubbers to cut emissions. Governments can enforce stricter regulations against polluters. Expanding green cover can help absorb carbon dioxide while providing much-needed oxygen. Rural households can shift from coal and firewood to clean fuels such as LPG and biogas, reducing both indoor and outdoor pollution.

We stand at a crossroads. Climate change and air pollution are not distant possibilities but present realities shaping our daily lives. Every drought, every flood, every toxic breath is a reminder of how precarious our existence has become. The question is no longer whether we can prevent these crises, but whether we can act fast enough to slow them, adapt, and secure the possibility of a livable future.

The time to act is not tomorrow. It is today. The heating Earth and the choking air will not wait.

Lata Mangeshkar, a Dalit from Devdasi family, 'refused to sing a song' about Ambedkar

By Pramod Ranjan* An artist is known and respected for her art. But she is equally, or even more so known and respected for her social concerns. An artist's social concerns or in other words, her worldview, give a direction and purpose to her art. History remembers only such artists whose social concerns are deep, reasoned and of durable importance. Lata Mangeshkar (28 September 1929 – 6 February 2022) was a celebrated playback singer of the Hindi film industry. She was the uncrowned queen of Indian music for over seven decades. Her popularity was unmatched. Her songs were heard and admired not only in India but also in Pakistan, Bangladesh and many other South Asian countries. In this article, we will focus on her social concerns. Lata lived for 92 long years. Music ran in her blood. Her father also belonged to the world of music.

Beyond Lata: How Asha Bhosle redefined the female voice with her underrated versatility

By Vidya Bhushan Rawat* The news of iconic Asha Bhosle’s ‘untimely’ demise has shocked music lovers across the country. Asha Tai was 92 years young. Normally, people celebrate a passing at this age, but Asha Bhosle—much like another legend, Dev Anand—never made us feel she was growing old. She was perhaps the most versatile artist in Bombay cinema. Hailing from a family devoted to music, Asha’s journey to success and fame was not easy. Her elder sister, Lata Mangeshkar, had already become the voice of women in cinema, and most contemporaries like Shamshad Begum, Suraiya, and Noor Jehan had slowly faded into oblivion. Frankly, there was no second or third to Lata Mangeshkar; she became the first—and perhaps the only—choice for music directors and all those who mattered in filmmaking. Asha started her musical journey at age 10 with a Marathi film, but her first break in Hindustani cinema came with the film "Chunariya" (1948). Though she was not the first choice of ...
