People use roadside tap water to cool down themselves during the heat wave in Dhaka, Bangladesh, April 26, 2024. The country's capital, Dhaka, saw the temperature reach 40.6 degrees Celsius (105.1 degrees Fahrenheit) on April 16, the highest in 58 years, making people's lives unbearable for more than a week with low humidity in the air, according to Bangladesh Meteorological Department (BMD) officials. Five types of gas layers have been created in Dhaka's air. These gases have been produced from garbage dumps, brick kilns, vehicles and the fumes emitting from industries. These gases are increasing the temperature of Dhaka's air and the ground. Added to the heat wave, these harmful gases are making Dhaka weather intolerable. These observations were made in two recent surveys conducted by a group of scientists. Photo by Suvra Kanti Das/Abaca/Sipa USA
