The atmospheric temperature has increased and all episodes are obvious worldwide. It is no longer a message. How the temperature increase in our country has a living and our health has so far been unclear. A study supported by the World Bank analyzed data on national temperature and moisture trends for the period from 1976 to 2023. The results of the studies were published on September 16, 2024 in the report entitled “A non-sustainable life: the effects of the heat on the health and economy of Bangladesh”.
According to the report “Bangladesh's maximum temperature has increased by 1.1 degrees Celsius since 1980, while the” temperature “has increased by 4.5 degrees Celsius, which leads to an increase in health problems such as diarrhea, persistent cough, breathing and fatigue. Including the mental health problems, depression, anxiety, loss of economic productivity and prosperity. Bangladesch is currently in second place. Improvement of health systems to manage heat disease. To get infrastructure for the mitigating effects of global warming.
The temperature rise in the atmosphere leads to a comparatively lower adverse effects for rich countries. However, the increased hit affects disproportionate poor nations. In addition, increased heat and climate change affect the productivity of the food grain worldwide, which leads to a price increase. The poor nations that depend on the import of food suffered seriously from the price increase. Thus, climate change can have the effects in part of the world serious effects on other parts of the world.
The increase in temperature and moisture has increased the demand for requirements for air conditioning systems and cooling. Published reports indicate that the electricity consumption for air conditioning and cooling has quickly increased worldwide. According to available information, the USA use as much electricity to keep the buildings cool as the entire Africa uses for all possible needs. China and India have caught up with the US current consumption. The demand for cold interior and a rapidly growing middle class population in developing countries has pushed the requirements for air conditioning up. City like Mumbai in India consumes about 40 percent of their total power consumption power. The Kingdom of Saudi Arabia burns one billion barrels of oil a year for the needs of air conditioning. The investigation by the Netherlands Assessment Agency predicts that by 2060 people will consume more energy for cooling than heating until 2060. The International Board for Climate Change (IPCC) estimates that electricity consumption will increase solely for the requirements of air conditioning in residential areas from 300 terawatt hours per year in 2000 to 4,000 terawatt hours in 2025 and 10,000 tterawatt hours in 2100.
However, the energy consumption for the support of cooling systems (air conditioning and cooling) pollutes the environment for the generation of electrical energy and by breaking out refrigerant gases, which leads to cumulative increase in greenhouse gases in the atmosphere.
Unplanned urbanization leads to a loss of wetlands and green coverage. Random structures/buildings take off the heat of the sun more than natural landscapes. In the urban areas, a “heat effect” begins to act, where the green coverage is limited and buildings, roads and high energy consumption are concentrated by commercial infrastructures. This urban “heat island effect” releases higher temperatures for surrounding areas. The buildings and infrastructure use more air conditioning systems to cool off. Due to the heated environment and the heat effect, more and more air conditioning systems are required. In view of the costs and the negative environmental impacts (both domestic and global environmental data, the development strategies in Bangladesh demand radical review. Vegetation with trees and green roofs, preservation of water and green coverage and waters in urban areas can help to improve efficient construction design and physical comfort.
