Dhaka, the densely populated capital of Bangladesh, ranked 10th among the world’s most polluted cities on Saturday morning, recording an Air Quality Index (AQI) of 115 at 09:27 am. Today's air was classified as ‘unhealthy for sensitive groups’, referring to a health threat, according to the AQI index. India’s Delhi, Thailand’s Chiang Mai and Egypt’s Cairo occupied the first three spots on the list, with AQI scores of 254, 223 and 200, respectively. AQI levels of 101–150 are ‘unhealthy for sensitive groups’, 151–200 is ‘unhealthy’, 201–300 is ‘very unhealthy’, and readings above 301 are considered ‘hazardous’, posing severe health risks. The AQI, which reports daily air quality, informs residents how clean or polluted the air is and highlights potential health effects. In Bangladesh, the AQI is calculated based on five key pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. Dhaka has long struggled with air pollution. Air quality usually deteriorates in winter and improves during the monsoon season. The World Health Organization (WHO) estimates that air pollution causes about seven million deaths worldwide each year, primarily from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.      

Dhaka ranked eighth among cities worldwide with the worst air quality on Friday morning. The capital recorded an Air Quality Index (AQI) score of 151 at 08:45am, which was classified as “unhealthy”, according to IQAir. Thailand's Chiang Mai topped the list with an AQI score of 194. Nepal’s Kathmandu ranked second with a score of 173, while South Korea's Seoul placed third, also recording an AQI score of 173. An AQI between 151 and 200 is considered unhealthy, meaning everyone may begin to experience health effects, with sensitive groups facing more serious risks. When the AQI value for particle pollution is between 101 and 150, air quality is considered ‘unhealthy for sensitive groups’, between 151 and 200 is ‘unhealthy’, between 201 and 300 is said to be 'very unhealthy', while a reading of 301+ is considered 'hazardous', posing serious health risks to residents. The AQI, an index for reporting daily air quality, informs people how clean or polluted the air of a certain city is and what associated health effects might be a concern for them. The AQI in Bangladesh is based on five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone. Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon. As per World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, mainly due to increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.  

Dhaka, the densely populated capital of Bangladesh, ranked 6th among the world’s most polluted cities Thursday morning, recording an Air Quality Index (AQI) of 162 at 10:55 am. Today, the city’s air was classified as ‘unhealthy’, indicating a serious health threat, according to the AQI report. Beijing in China, Delhi in India, and Chiang Mai in Thailand occupied the first, second, and third spots on the list, with AQI scores of 236, 198, and 181 respectively. According to the AQI scale, a reading between 50 and 100 is considered ‘moderate’, with generally acceptable air quality, though sensitive individuals should limit prolonged outdoor exertion. AQI levels of 101–150 are ‘unhealthy for sensitive groups’, 151–200 is ‘unhealthy’, 201–300 is ‘very unhealthy’, and readings above 301 are considered ‘hazardous’, posing severe health risks.

Bangladesh is likely to see an additional 24 deaths per 100,000 people each year due to rising temperatures by 2050, says a new report on Wednesday that places Bangladesh among the 25 most affected countries globally for heat-related mortality. The new report from the Climate Impact Lab finds that climate change is projected to increase these premature deaths and that more than 90 percent of them are slated to occur in low- and middle-income countries. In Khulna, that number rises to 36 deaths per 100,000, exceeding the current death rate from chronic obstructive pulmonary disease in the country, according to the report. Dhaka is projected at 22 deaths per 100,000, Chittagong at 12, according to the report on the impact of rising temperatures on mortality underscores the need for targeted investments to help people and communities save lives. The study is the first in a series to identify where and what climate adaptation investments will be most beneficial. Record-breaking heat waves grab the headlines each summer because they cause tens of thousands of deaths. The report underscores that targeted adaptation investments can substantially save lives, as temperature-related mortality will depend both on the direct impacts of a warming climate and on the investments that people and governments make to protect human health. “This report uncovers one of climate change’s cruelest ironies - it is projected to kill millions of people in the countries that have generally done the least to cause it. Further, their relatively low income levels mean that they are not as well positioned as people in rich countries to confront the new and unfolding risks from climate change,” says Michael Greenstone, a co-founder of the Climate Impact Lab and the director of the Institute for Climate and Sustainable Growth and Energy Policy Institute at the University of Chicago. “In this report, we’ve identified the regions around the world where climate adaptation investments can save the most lives.” The report is based on the Climate Impact Lab’s landmark projections of temperature-related mortality. These are the first projections of rising temperature’s impacts on mortality, based on highly-localized data from around the world.  They highlight that the extent to which adaptation reduces temperature-related mortality hinges on the choices that governments and people make, including investments in air conditioning, cooling centers and other adaptive measures. The findings from the new report underscore the inequality of climate change. The issue is not only that warmer regions are set to experience higher mortality than cooler ones, but also that the greatest impacts are projected to fall on regions that are both hotter and poorer, as they have fewer resources for adaptation. For example, the country of Burkina Faso in West Africa is projected to experience double the number of deaths from heat than the wealthier country of Kuwait in the Middle East, despite their similar climates. Overall, ten times more people are projected to die from the heat in poor countries than in rich countries by 2050. The same pattern happens at the city level. More than 15 times more people are projected to die from the heat in Faisalabad, Pakistan, than in the hot - but wealthy - city of Phoenix, Arizona. In fact, the number of people projected to die from heat in many Pakistani cities in 2050 will exceed the number dying from COPD and stroke today. “The report reveals who stands to gain the most from targeted adaptation investments. The regions where increases in mortality are highest are also those with few resources, limited government capacity, and a weak history of attracting international private investment,” says Tamma Carleton, Faculty Head of Research for the Climate Impact Lab and an Assistant Professor at the University of California, Berkeley. “The stakes are too high for the past to be the prologue. Correctly choosing where to spend limited dollars on adaptations could have massive impacts on who lives and who dies.” The report is the first in a new “Adaptation Roadmap” series that takes as its starting point the urgent need to embrace adaptation as a central part of the strategy to confront climate change, alongside greenhouse gas emissions mitigation. The series is part of an expanded mission for the Lab. Building off a decade of research on the impacts of climate change, the Lab is now working to uncover not only where adaptation will be most needed but also the benefits to specific investments. In addition to characterizing the risks local communities face, the Lab is also developing a global playbook of data-driven, tested adaptation strategies for investors, national and local governments, and the people that will increasingly face climate risks. “Just as a journey requires a map, effective climate adaptation depends on knowing where action is most needed and which investments will have the greatest impact,” said Greenstone when the Lab announced its expanded mission. “We’re providing that roadmap by pinpointing climate risks and the places where adaptation investments can deliver the biggest benefits.” The diverse climates and economies of Asian countries combine to drive a wide range of outcomes in our temperature-related mortality projections for the continent. Climate scientists change El Nino labeling as temperatures spike CIL projections indicate that 95 cities across Asia will experience an increase in temperature-related mortality of at least 10 deaths per 100,000 with 56 of them residing in China. Additional deaths due to climate change in those heavily populated areas of China will be on par with the number of lives currently lost to both esophagus and colon cancer. Other countries with multiple cities that exceed the 10 deaths per 100,000 threshold include Pakistan (9), Japan (4), Iran (4), Bangladesh (3), and Saudi Arabia (3). Elsewhere, in Gaziantep, Turkey, the increase in mortality due to climate is on par with that of lower respiratory infections and in Khulna, Bangladesh, it exceeds the current death rate due to chronic obstructive pulmonary disease (COPD).

Bangladesh Meteorological Department(BMD) has predicted  rain  or thunder showers in parts of the country in 24 hours from 9 am on Wednesday.  “Rain/thunder showers accompanied by temporary gusty wind and lightning flashes is likely to occur at one or two places over Rajshahi, Rangpur, Dhaka, Mymensingh, Chattogram & Sylhet divisions,” said a Met office bulletin. Weather may remain mainly dry with temporary partly cloudy sky elsewhere over the country, it added. Day and night temperature may rise slightly over the country.

The World Meteorological Organization has warned that the Earth’s climate system is becoming increasingly unstable, driven by record levels of greenhouse gases and rising global temperatures. The UN agency said the planet is now “more out of balance than at any time in recorded history,” following an exceptionally hot decade. Between 2015 and 2025, the world experienced its 11 warmest years on record, with 2025 registering around 1.43°C above pre-industrial levels. According to WMO officials, continued warming is accelerating glacier melt and contributing to rising sea levels, as both oceans and land-based ice respond to increasing temperatures. The agency also reported that concentrations of key greenhouse gases — including carbon dioxide, methane and nitrous oxide — reached record highs in 2024, with further increases observed in 2025. These gases are disrupting the Earth’s energy balance by trapping more heat within the atmosphere. Experts explained that the planet is currently absorbing more energy from the sun than it is releasing back into space, leading to a growing energy imbalance. This excess heat is largely stored in the oceans, which absorb about 90% of it. The WMO noted that this trend is particularly concerning for vulnerable populations, especially those living in coastal areas. More than three billion people depend on marine and coastal ecosystems, while around 11% of the global population lives in low-lying regions at risk from rising sea levels and climate-related hazards. The agency called for stronger efforts to improve early warning systems and climate resilience measures to protect lives and livelihoods worldwide.

Bangladesh Meteorological Department predicted  rain  or thunder showers accompanied by temporary gusty or squally wind and lightning flashes in parts of the country in 24 hours from 9 am on Friday.  “Rain or thunder showers accompanied by temporary gusty/squally wind and lightning flashes is likely to occur at a few places over Rangpur, Rajshahi, Dhaka, Mymensingh & Sylhet divisions and at one or two places overKhulna, Barishal and Chattogram divisions with hails at isolated places,” said a Met office bulletin. Day temperature may fall slightly and night temperature  is likely to remain nearly unchanged over the country, it added.
