ISLAMABAD (Eshfak Mughal):- Hot weather has set new records in the Northern Hemisphere during the current year as America, Europe, Asia and Africa experienced unusual heat waives that could be part daily life in summer in future.
Currently, European countries including Britain, France, Spain and Portugal are experiencing a heat wave, which have affected millions of people as well as forest fires.
Spain and Portugal alone recently reported more than 1,000 deaths due to rising temperatures.
For the first time in the history of the United Kingdom, a temperature of more than 40 degrees Celsius was recorded in the country. Europe is in the grip of extreme heat, the mercury is forecast to reach 41 degrees in the UK.
Forest fires in France have left thousands homeless, Britain’s hottest day on record on July 19. But Europe is not the only one affected by the extreme hot weather, but from China to North Africa and America have also faced it.
Heatwaves are becoming more common due to the increase in global temperature, but the year of 2022 was emerged as a more prominent one in this regard.
But scientists have warned that in coming years it will become part of the normal life, meaning people will experience longer heatwaves during the summer in future.
They emphasize that the world has to reduce the rate of emission of toxic gases that lead to rise in temperature worldwide.
But at the same time, the world must prepare to cope with the extreme level of temperature, such as limiting the use of asphalt (commonly used in road construction), which is heated by sunlight but melts in high temperatures.
Governments should also ensure that infrastructure is built to withstand extreme temperatures to reduce the incidence of wire meltdowns and power outages.
In March 2022, both the North and South Poles recorded record temperatures simultaneously, although this is the beginning of winter in the regions adjacent to the South Pole and spring at the North Pole.
At the same time, the wave of heat wave that lasted for 2 months started in Pakistan and India.
In June, the sun began to scorch the US and Europe, and various places in the world saw a record rise in temperature.
The scientists believe that this is the result of a global temperature increase of just 2 degrees Fahrenheit, and they are expecting another 4 degrees Fahrenheit increase over the period of this century.
Scientists have not always linked heat waves to climate change, but recent research reports have indicated this that the heat waves come due to climate change.
In May, a study regarding the heat wave in Pakistan and India stated that as a result of climate change, the probability of heat wave in Pakistan and India will increase more than 30 times compared to normal conditions.
As global temperatures rise overall, heat waves will become more common and their intensity and duration will increase.
A study found in 2018 that heatwaves in the US have tripled in duration and it has been increased to 45 days since the 1960s.
The United Nations Intergovernmental Panel on Climate Change has predicted that a similar climate trend will be seen around the world.
As heatwaves increase in frequency and duration, different parts of the world will experience severe heatwaves.
The scientists say that the some part of the world will experience a heat wave almost every day during summer in coming years.
In the 1980s, heatwaves lasted 20 to 30 days each summer, but due to increase in global warming, the number of heatwaves has increased by 6 time over the past 40 years. In the Journal of the American Meteorological Society found that heatwaves are now 17 percent more intense as compared to 40 years ago.
The experts involved in the research believe that the world is now facing a climate that will continue to increase in intensity of weather, scientists were predicting such conditions since the last decade.
They demand for an immediate reduction in the emission of toxic gases. They say that even that it is clear that the world will face record heat like this year in the coming years, but the temperature at this time will be even higher.
