Climate impact worries and warnings
The results of a survey of 10,751 people in India from December 5, 2024, to February 18, 2025, to better understand public experiences and worries about extreme weather events by the Yale Program on Climate Change Communication (YPCCC) and CVoter was released recently.
The Yale Climate Note on the survey points out that as the climate warms, extreme weather events are becoming more frequent and severe across India. Indians have recently experienced extreme heat waves, floods, water shortages, and irregular monsoon patterns. These not only harm lives and livelihoods but also shape how people perceive both climate change and extreme weather.
The note highlights that results showed that most respondents said they had personally experienced at least one extreme weather event or related impact in the past 12 months. Majorities had experienced severe heat waves (71%), agricultural pests and diseases (60%), power outages (59%), water pollution (53%), droughts and water shortages (52%), and severe air pollution (52%). More than half of Indians say they are 'very worried' about extinctions of plant and animal species (61%), severe heat waves (56%), agricultural pests and diseases (62%), droughts and water shortages (58%), water pollution (55%), severe air pollution (54%), and famines and food shortages (51%). Majorities think global warming is affecting extreme weather and related impacts in India. Half or more surveyed Indians say global warming is affecting extinctions of plant and animal species (64%), severe heat waves (62%), agricultural pests and diseases (62%), droughts and water shortages (60%), severe air pollution (59%), water pollution (57%), severe cyclones (54%), famines and food shortages (53%), severe floods (53%), monsoons (52%), and severe storms (50%) 'a lot.'
The survey found that related impacts are deeply worrisome for many in India. Worry about local impacts is widespread and closely mirrors people's personal experiences with these events. And, after hearing a definition of global warming, most respondents say that it is affecting these events (especially plant and animal extinctions, heat waves, and agricultural disruptions). However, a significant proportion (32%) of people in India have never heard of global warming. These findings highlight the critical need to raise public awareness about climate change and local climate impacts and reinforce the urgency of both reducing carbon pollution and preparing for future extreme events.
Another study was also conducted recently by the Potsdam Institute for Climate Impact Research and Climate Analytics and commissioned by the World Bank Group to better understand the risks of climate change to development and look at the likely impacts of temperature increases from 2°C to 4°C in three regions. A World Bank news feature on the study lists some of the warnings for India. India is already experiencing a warming climate with a decline in monsoon rainfall since the 1950s. The frequency of heavy rainfall events has also increased. Parts of South Asia have become drier since the 1970s with an increase in the number of droughts. In 1987 and 2002-2003, droughts affected more than half of India's crop area and led to a huge fall in crop production. Even without climate change, 15% of India's groundwater resources are overexploited. Most Himalayan glaciers have been retreating over the past century. Rapid and unplanned urbanization further increases the risks of sea water intrusion. Even without climate change, world food prices are expected to increase due to growing populations and rising incomes, as well as a greater demand for biofuels.
The feature adds that climate-related impacts on water resources can undermine the two dominant forms of power generation in India – hydropower and thermal power generation – both of which depend on adequate water supplies to function effectively. Many parts of India are already experiencing water stress. Urbanization, population growth, economic development, and increasing demand for water from agriculture and industry are likely to aggravate the situation further. Climate change is expected to have major health impacts in India with the poor likely to be affected most severely. South Asia is a hotspot for the migration of people from disaster-affected or degraded areas to other national and international regions. The Indus and the Ganges-Brahmaputra-Meghna Basins are major transboundary rivers, and increasing demand for water is already leading to tensions among countries over water sharing.

Working towards a climate-resilient future
A recent conference 'India 2047: Building a Climate-Resilient Future' brought together leading experts in climate science, public health, medicine, labour, business, agriculture, and urban planning for a series of interdisciplinary dialogues on advancing climate resilience. The conference, according to its website, addressed the effects of extreme climatic events such as extreme heat intensifying across the Global South – particularly in India – with far-reaching impacts on the environment, economy, and society demanding urgent, evidence-based solutions. Startlingly, as an analysis in the ScienceAdviser pointed out, at this conference, scientists said that despite its extreme heat waves, the country's decades-long warming trend amounts to half the global average. The analysis goes on to highlight a surprising statistic. On a world map showing how 2024 temperatures deviated from a historical baseline, many countries were coloured deep red, denoting an increase of 1°C to 2°C. But one large, pale spot stood out in the tropics. As Indians gird themselves for what could be a third summer in a row of extreme heat, the analysis says, they might be surprised to hear their country is warming more slowly than many others. Last year, India saw its highest recorded temperature and its longest spell of heat waves. But annual mean temperatures have risen by less than 0.7°C since 1901—about half the global average. Scientists do not fully understand why. Key learnings from the conference were summarized by its Scientific Committee and put out on the conference website. The warming over the subcontinent over the next few decades is likely to be much faster than what has been experienced in the past. Rainfall will continue to become more intense, but more sporadic. Climate scientists can work together to improve weather and climate forecasts – of the onset of the monsoon, for example, or of peak temperatures during the pre-monsoon season. But there are limitations to their skill in predicting weather and climate, and surprises are inevitable. The takeaway lesson is that the country must begin to prepare for new conditions never seen before across the subcontinent – and that preparation must begin now. One way to prepare is to make sure that the forecasts from climate science are effective for the end-users, who have distinct needs and priorities. Preparing for climate change means developing forecasting tools that are customized to their specific contexts. And this will lead to more relevant and actionable plans for adaptation. In the health sector, the conference found that progress has been made in data collection, but significant unknowns remain regarding the liveability in extreme heat conditions. The current understanding of mortality and heat exposure at the city scale is crude, and there is a pressing need for more granular data to identify those most at risk, but experts know enough to guide sensible public health decisions already. Health data is fragmented but there are encouraging efforts across India to digitize and integrate health records. Discussion groups identified the key value of a timely census for accurate epidemiological estimates of climate impacts on health. In general, there is much uncertainty about long term health outcomes, since there are overlapping challenges that intersect in synergistic ways – a key example is nutrition, non-communicable diseases, and susceptibility to infectious diseases. Workers are already adapting to worsening heat conditions and have begun organizing in response to these challenges. However, discussants agreed that broader social dialogues between government entities, businesses, and labour groups remain a priority, and it is critical to include workers in the conversation. Sector-specific triggers could be considered to capture the full spectrum of worker impacts. More research is needed to understand worker-level heat exposure. Also, the built environment operates at multiple scales, including buildings, urban design, and urban planning. Policy, market forces, and education each play a crucial role in shaping climate-responsive infrastructure. Innovations and solutions must be contextualized in all the various contexts of India. Across groups, the conference sessions identified challenges associated with differing timescales of priorities, where long-term sustainability may be at odds with short-term needs. Experts at this convening included government, academia, civil society, and the private sector, aiming to foster collaboration, bridge critical knowledge gaps, and shape actionable research and policy frameworks for a sustainable and climate-resilient future.

Foul air and vitamin B12 deficiency main reason for anaemia in India
While anaemia is long known to be caused by iron deficiency, experts on Thursday noted that air pollution and vitamin B12 deficiency have emerged as major culprits behind its increasing prevalence in the country. Anaemia occurs when there isn't enough haemoglobin in the body to carry oxygen to the organs and tissues. The condition, which mainly affects women and children, leads to the lower count of red blood cells or the haemoglobin. In severe cases, anaemia can cause poor cognitive and motor development in children. 'Emerging research has suggested that anaemia in India is not solely due to iron deficiency. Two additional factors warrant attention: air pollution and vitamin B12 deficiency,' Dr K Madan Gopal, a public health expert working at the National Health Systems Resource Center, a premier think tank of the Health Ministry, New Delhi, told reporters. A recent study led by the Indian Council of Medical Research (ICMR), published in the peer-reviewed European Journal of Clinical Nutrition, found that iron deficiency contributes only marginally to its prevalence, with the other two factors playing a much larger role in the widespread occurrence of anaemia in the country. Gopal explained that exposure to fine particulate matter (PM2.5) can lead to systemic inflammation. This inflammation interferes with the production and survival of red blood cells, exacerbating anaemia. 'Efforts to improve air quality at the community level -- such as local monitoring of pollution sources and public education on pollution mitigation -- can positively impact overall health and, by extension, reduce inflammation-induced anaemia,' the expert said. 'Long-term PM2.5 exposure lowers haemoglobin levels by 2-3 per cent, increasing anaemia risk by 12-15 per cent,' Dr. Sabine Kapasi, advisor, United Nations Covid-19 Task Force, told reporters. In addition, vitamin B12 is also crucial for properly forming red blood cells. In populations with predominantly vegetarian diets, inadequate vitamin B12 intake is common. 'Over 50 per cent of Indians lack vitamin B12 due to poor diets, leading to megaloblastic anaemia -- marked by weakness, dizziness, and cognitive issues,' Kapasi said. Anaemia remains a significant public health challenge in India. The recent data from the National Family Health Survey (NFHS-5) indicate that approximately 57 per cent of women of reproductive age and 67 per cent of children aged 6-59 months are affected by anaemia. To fight the condition, the government has rolled out Anemia Mukt Bharat which focuses on supplementing diets with iron and folic acid, fortifying staple foods, and strengthening primary healthcare delivery. However, Gopal noted that addressing anaemia requires more than top-down approaches. 'At the community level, we must empower local health workers, community leaders, and non-governmental organisations to take ownership of anaemia as a critical health concern. By integrating nutritional education into local outreach programmes, communities can be encouraged to adopt diversified diets and better hygiene practices. Anaemia must become a 'felt need' at the grassroots level,' he told IANS. Alongside iron supplementation, the experts also suggested educating communities on the importance of a balanced diet that includes B12-rich foods or fortified alternatives; and early screening for B12 levels. They also urged a holistic approach with the fortification of staples like rice and wheat, targeted nutrition awareness, and tackling environmental triggers like air pollution to fight anaemia. On the other hand, while air pollution is becoming a growing health issue worldwide, a new study focussed on its health and economic costs in the elderly. The study led by researchers from the University of Tokyo in Japan highlights how fine particulate pollution, or PM2.5 worsens health outcomes, as well as creates significant socioeconomic challenges in regions with ageing populations and limited medical resources. PM2.5 refers to microscopic particles of pollution small enough to penetrate deep into the lungs and bloodstream, leading to severe respiratory and cardiovascular diseases. The particles are small enough to evade the body's natural defences in the nose and throat, making direct prevention difficult. This becomes especially problematic in elderly populations. 'As we age, our immune systems weaken and our bodies are less able to defend against pollutants. Even moderate exposure can exacerbate pre-existing conditions, leading to higher hospitalisation rates and premature mortality,' said lead author Associate Professor Yin Long. 'Our study provides new insights into impacts of PM2.5 in ageing regions, with a particular focus on the mismatch between those impacts and regional medical resource distribution.' The team focuses on Japan -- a country where almost 30 per cent of the population is aged 65 or older. Examining the relationship between PM2.5 exposure, health care disparities, and economic impacts, the team found that elderly people living in rural regions suffer more from PM2.5 pollution.
