During the hot summer day Bangladeshi people collect drinking water from a street side water supply, in Dhaka, Bangladesh, April 22, 2024. The country�s capital, Dhaka, saw the temperature reach 40.6� Celsius (105.1� 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
