As temperatures across India’s capital continue to climb during another summer of extreme heat, the impact is being felt most acutely by those with little protection from the elements. For the hundreds of thousands of people living on Delhi’s streets, daily life unfolds under relentless heat, limited access to essential services and constant uncertainty about safety and survival.

Among them is Shahida, a 20-year-old mother who lives with her family beneath a flyover in Delhi. Their home consists of a section of pavement where they sleep under mosquito nets and store their belongings. Throughout the day and night, they remain exposed to conditions that climate experts say are becoming increasingly dangerous as heatwaves intensify across the region.

Delhi has been experiencing sustained high temperatures, with daytime readings regularly reaching 43 degrees Celsius. Nighttime temperatures have also remained unusually elevated, providing little relief after sunset. According to reported meteorological data, the city recently recorded its warmest May night in nearly 14 years.As authorities issue repeated heat alerts and many residents seek refuge indoors, an estimated 300,000 people living without permanent shelter continue to face direct exposure to extreme temperatures.

Their vulnerability extends beyond heat alone, encompassing challenges related to food security, drinking water, sanitation and healthcare access.Climate researchers say homelessness significantly increases the risks associated with extreme weather.

Chandni Singh, a lead author with the Intergovernmental Panel on Climate Change, noted that people without stable housing often lack reliable access to basic resources required to cope with prolonged periods of heat.“Beyond exposure alone, homelessness is often accompanied by unreliable access to food, water and healthcare all of which are essential to cope with and adapt to extreme heat,” Singh said.

The consequences can be severe. According to a report by the Centre for Holistic Development, at least 192 homeless individuals died during a nine-day period of extreme heat in Delhi last summer. The deaths highlighted the disproportionate burden borne by vulnerable populations during heatwave conditions.

For Shahida, summer brings anxiety long before temperatures reach their highest levels. Having spent most of her life living in similar circumstances, she said the arrival of hotter months is accompanied by concerns about health, safety and the wellbeing of her young daughter, Jannat.Throughout the day, the family must manage basic needs while exposed to intense heat.

Access to cold drinking water is limited. They rely in part on a nearby public institution that permits them to fill containers during evening hours, allowing them to store water for later use. The supply, however, remains constrained and dependent on availability.The challenge of securing shelter is equally significant.

According to Indu Prakash Singh, a member of a state-level shelter monitoring committee established by India’s Supreme Court, Delhi faces a substantial shortage of accommodation for homeless residents. He estimates that the city’s shelter capacity falls short of demand by approximately 75%, leaving many families with few alternatives to sleeping outdoors.

Although a women’s night shelter operates less than 200 metres from where Shahida’s family sleeps, she said conditions inside often provide little respite from the heat.“It is even hotter inside than outside,” she said.The concern is echoed by shelter advocates. Singh said many facilities consist of portable cabin-style structures that absorb and retain heat during summer months.

In some locations, cooling systems are insufficient or non-functional, reducing their effectiveness during periods of extreme weather.Conditions inside shelters can also become crowded, particularly during heatwaves when more people seek relief. Reports from facilities in Delhi indicate that access to cooling equipment is often limited, leading to competition among residents for the coolest spaces.As evening approaches and temperatures begin to decline slightly, daily routines continue beneath the flyover.

Families prepare simple meals, organize belongings and make arrangements for the night. Shahida’s family reheats rice and curry cooked earlier in the day before setting up sleeping mats on the pavement.The reduction in temperature after sunset offers only partial relief.

Even at night, the heat remains significant, and concerns about security persist. Women living on the streets frequently report remaining alert long after lying down to sleep, aware of potential risks to themselves and their children.Shahida said rest is often difficult to achieve despite physical exhaustion. The combination of environmental stress, uncertainty and responsibility for a young child creates a constant state of vigilance.

“Even when your eyes close, your mind stays awake. I need to be always protective of myself and my child,” she said.Around her, other families settle in for the night under mosquito nets and makeshift shelters. Some fan children in the humid air while others arrange possessions in an effort to create a small sense of privacy amid the traffic and noise of the city.

Experts increasingly view such experiences as evidence of the broader social consequences of climate change. Rising temperatures, more frequent heatwaves and warmer nights are expected to place additional strain on urban populations, particularly those lacking adequate housing and access to public services.For homeless residents, adaptation options remain limited.

Without permanent shelter, air conditioning or reliable access to cooling infrastructure, exposure to dangerous temperatures becomes an unavoidable feature of daily life.As traffic continues to flow above and around the flyover where she lives, Shahida said her focus remains on caring for her daughter and enduring each day as it comes.

Looking at the child sleeping beneath a mosquito net on the pavement, she described Jannat as the source of her determination to keep going despite the hardships of life on the streets.“Maybe she is the only hope I still hold on to,” Shahida said. “Otherwise, I don’t know what is left.”

The incident occurred at an aerospace facility in Garden Grove, southeast of Los Angeles, where a storage tank holding about 7,000 gallons (26,000 liters) of methyl methacrylate developed a leak. Emergency officials warned that the situation posed significant risks to nearby communities due to the chemical’s flammable nature and the possibility of a thermal runaway reaction.

Incident Commander Craig Covey said emergency planners were preparing for two primary scenarios: a complete tank failure resulting in a large chemical spill or an explosion that could affect neighboring tanks containing fuel and other hazardous materials.

“We are setting up these evacuations in preparation for these two options,” Covey said, describing the threat as serious and requiring immediate precautionary measures.

Garden Grove Police Chief Amir El-Farra said approximately 40,000 people were covered by the evacuation order, although several thousand residents chose to remain in their homes despite warnings from authorities.

Emergency crews continuously sprayed water on the tank in an effort to reduce its temperature and stabilize conditions. Later on Friday, Covey reported that cooling operations had succeeded in lowering the tank’s temperature to about 61 degrees, closer to what officials described as a safe operating range.

Authorities continued searching for alternatives that could further reduce the risk of either a major spill or an explosion.

Orange County Health Officer Regina Chinsio Kwong said the evacuation zone was established to protect residents from potential exposure to hazardous vapors in the event of a catastrophic failure.

She urged the public to report any detection of a strong fruity odor associated with methyl methacrylate, while noting that the smell alone did not necessarily indicate harmful exposure levels.

No injuries had been reported as of Friday evening, and officials had not determined the cause of the leak, which was first identified on Thursday.

Emergency responders were also preparing containment measures to prevent any released chemical from entering storm drains, waterways or channels that flow into the Pacific Ocean.

According to the U.S. Environmental Protection Agency, methyl methacrylate can irritate the skin, eyes and respiratory system. Acute or prolonged exposure may also result in respiratory and neurological effects.

The Philippine Institute of Volcanology and Seismology said the incident occurred before nightfall on Saturday when accumulated lava on the volcano’s southwestern slope gave way, sending an avalanche of hot rocks, ash and gas downslope.

The agency’s director, Teresito Bacolcol, said the volcano has been exhibiting mild eruptive activity intermittently since January but emphasized that no explosive eruption had taken place.Authorities reported no casualties, though ash clouds spread across 87 villages in three towns, reducing visibility to near zero in some areas and disrupting road movement.

Caloy Baldo, mayor of Camalig, said residents were caught off guard by the density of the ashfall, which he described as severe enough to halt traffic along national roads.Local officials said agricultural losses were reported, particularly in vegetable farms, while livestock deaths included four water buffaloes and one cow.

Cleanup operations were underway in affected communities, including Camalig, which has a population of about 8,000 people.The volcano, rising 2,462 meters and known for its near-symmetrical cone, is among the Philippines’ most active and closely monitored.

Authorities had raised its alert status to Level 3 in January, indicating heightened unrest with potential for hazardous eruptions, including rockfalls and pyroclastic flows.Bacolcol said conditions had stabilized as of Monday but warned that the threat of further activity remained, noting that the volcano’s behavior continues to require close monitoring under the current alert level.

Across large parts of Asia, rising temperatures, rapid urban expansion, and environmental degradation are contributing to a measurable increase in human-wildlife conflict, according to conservation groups and environmental researchers.

From snakebites in rural India to elephant incursions in agricultural zones and leopard sightings in urban peripheries, experts say these incidents reflect deeper ecological disruptions linked to climate variability and land-use change.

Data compiled by the World Health Organization indicates that snakebite envenoming alone remains a major public health issue, with millions of cases reported annually worldwide, disproportionately affecting rural populations.

Environmental scientists note that warmer climates are altering reptile behavior, extending active seasons and expanding habitats into areas with higher human density.India has recorded a steady stream of incidents involving venomous snakes entering residential zones, particularly during unusually warm or erratic weather patterns.

Researchers attribute this to both habitat encroachment and climatic shifts that influence prey availability and breeding cycles. Similar patterns have been observed in parts of Southeast Asia, where deforestation has forced wildlife into closer proximity with human settlements.

Beyond reptiles, large mammals are also increasingly involved in conflict scenarios. Reports from eastern India and parts of Sri Lanka show that elephant populations, traditionally migratory, are encountering barriers such as highways, railways, and expanding farmland. This has led to crop damage, property destruction, and fatalities on both sides.

Conservationists argue that fragmented habitats are disrupting established migration corridors, intensifying interactions.Urbanization is another significant factor. Expanding cities are absorbing forest fringes, creating transitional zones where wildlife adapts to human presence. Leopards in India, for example, have been documented navigating densely populated outskirts, often surviving on stray animals.

While such adaptation demonstrates ecological resilience, it also raises safety concerns.According to United Nations Environment Programme, human-wildlife conflict is emerging as a critical issue globally, driven by population growth, infrastructure development, and climate change.

The agency has emphasized that these interactions are not isolated incidents but part of a broader trend affecting biodiversity and human livelihoods.Government responses have varied. In India, state authorities have implemented measures such as rapid response teams, compensation schemes for affected families, and awareness campaigns aimed at reducing panic and promoting coexistence.

However, experts argue that these measures often address symptoms rather than underlying causes.“Mitigation strategies must include habitat restoration and the preservation of ecological corridors,” said a conservation researcher involved in wildlife tracking programs. “Without addressing land fragmentation, conflicts will continue to escalate.”

Technological interventions are also being explored. Early warning systems using GPS tracking, drone surveillance, and community-based monitoring networks are being deployed in select regions. These systems aim to alert residents to the presence of large animals, reducing the likelihood of surprise encounters.

At the same time, public health systems are under pressure to respond to the medical consequences of these interactions. Snakebite treatment, for instance, remains unevenly distributed, with rural areas often lacking access to timely antivenom. This gap highlights the intersection between environmental change and healthcare infrastructure.

Experts stress that wildlife itself is not the primary driver of these conflicts. Animals typically avoid human interaction and are forced into contact due to shrinking habitats and resource scarcity. From an ecological standpoint, many of these species play essential roles, such as controlling pest populations or maintaining ecosystem balance.The challenge, therefore, lies in balancing development with conservation.

Policymakers are increasingly being urged to integrate environmental considerations into infrastructure planning, particularly in biodiversity-rich regions. Failure to do so could exacerbate both ecological damage and human risk.

As climate models project continued warming and population pressures persist, the frequency and intensity of human-wildlife encounters are expected to rise.

Researchers emphasize that long-term solutions will require coordinated efforts across sectors, including urban planning, conservation policy, and public health systems.

The ongoing reduction in Arctic sea ice is beginning to reshape global maritime trade patterns, with shipping companies and governments increasingly evaluating northern sea routes as viable alternatives to traditional corridors such as the Suez Canal.

According to data from the International Maritime Organization, seasonal navigability in Arctic waters has improved over recent decades, allowing limited commercial transit during summer months.

The Northern Sea Route, running along Russia’s Arctic coastline, has drawn particular attention due to its potential to shorten travel distances between Asia and Europe by up to 40% compared with southern routes.

This reduction in distance translates into lower fuel consumption and shorter delivery times, although operational constraints remain significant.

Shipping activity along this corridor remains modest but is increasing incrementally, with vessels requiring ice-class certification and often escort by icebreakers. Russian authorities have expanded infrastructure investments in Arctic ports and navigation systems to support growing traffic.

The expansion of Arctic navigation is directly linked to rising global temperatures and declining ice cover. Scientific assessments indicate that the Arctic is warming at a rate significantly faster than the global average, contributing to longer ice-free periods.

However, variability in ice conditions continues to pose risks, including unpredictable weather patterns and limited search-and-rescue capabilities.Environmental concerns have also emerged as a key constraint.

The Arctic ecosystem is highly sensitive to disturbances, and increased shipping raises the risk of oil spills, black carbon emissions, and disruption to marine biodiversity.

Regulatory frameworks under the International Maritime Organization, including the Polar Code, set standards for safety and environmental protection, but enforcement and monitoring remain complex.

The strategic importance of Arctic routes has heightened geopolitical competition among major powers. Russia maintains the most developed Arctic infrastructure and asserts regulatory control over the Northern Sea Route, while countries including China have described the region as part of a broader “Polar Silk Road” strategy.

The Arctic Council continues to serve as a platform for cooperation on environmental and scientific issues, though it does not govern commercial navigation. Analysts note that the intersection of economic opportunity, environmental risk, and sovereignty claims is likely to shape policy debates in the coming years.

Despite the potential advantages, industry adoption remains cautious due to high insurance costs, limited infrastructure, and legal uncertainties.

As a result, Arctic shipping is expected to complement rather than replace established global trade routes in the near term.
