Is the world we know changing as a result of climate change? Seeing the recent symptoms, it seems so. As a result of climate change, extreme weather events like heavy rains, droughts, heat waves or cold spells are increasing in the whims of nature. It is seen that there is a lot of natural disaster. With all this, the incidence of dangerous hot weather with high humidity is increasing. Researchers have recently released a number of important reports on climate change that are enough to make us think.
■The result of climate change is desertification
The Sahara Desert is one of the warmest regions in the world. Climate change will cause a large part of the land to become as hot as the Sahara Desert in 50 years, scientists say. About one-third of the world's people will be forced to live in that environment. Scientists say that the next half-century will see more changes in the world's climate than in the last 6,000 years.
■Danger of heat with high humidity
Our bodies have their own cooling system to deal with hot weather. Whenever the air temperature rises above the ideal temperature, sweat comes out on our skin. This sweat releases some heat from the body when it evaporates. It maintains a normal body temperature (96.6 degrees Fahrenheit).
In hot weather, if there is less water vapor in the air, sweating is normal. Less difficult than this kind of dry heat. But in hot weather, if the amount of water vapor in the air is high, the process of sweating is disrupted. Then the body's own cooling system becomes useless. This condition is not only difficult but also dangerous to health. As a result, the temperature inside the body may rise above normal. This can lead to damage to important limbs and can lead to various complications including heat stroke. It is not impossible for a person to die from it if he stays in such a state for a long time.
■Dangerous hot weather is increasing around the world due to climate change
A team of researchers recently published a landmark report on ongoing climate change.( According to them, the incidence of dangerously hot weather with high humidity on the earth has almost doubled between 1989 and 2017 due to climate change. )Not only has the number and intensity of such extremes increased, but the size of the affected areas has also increased.
The effects of such climate change are most pronounced in countries bordering the Persian Gulf. (These include Saudi Arabia, Qatar and the United Arab Emirates. In South Asia, India, Pakistan and Bangladesh are also concerned about the effects of hot weather due to climate change.) Extreme temperatures have also risen sharply in Africa, Europe, Australia, North and South America.
This report on climate change was recently published in the journal Science Advances. The researchers compiled the report by analyzing data on temperature and humidity recorded over the past 40 years recorded in six meteorological centers around the world. If the current trend of climate change continues, billions of people around the world will be forced to live in unbearable heat over the next 50 years, the report said.
■The new challenge of adapting to nature
Recent reports of climate change make us think. We may need to make a profound change in the way we experience the increasing incidence of extreme heat and extreme weather in various parts of the world, including South Asia.. Experts say that we need to make the necessary changes in everything from housing construction to lifestyle, food to work, from now on. It has now become urgent for people to survive in the new situation caused by climate change.
