All parts of the world are groaning in the unprecedented heat wave.



Heatwaves hit Europe over the weekend, with parts of France and Spain reaching over 40 degrees Celsius.



The New York Times (NYT) reported that heat waves are occurring simultaneously in various parts of the globe, including the United States, Europe, and Asia, and this phenomenon will continue in the future.



In the United States, where the heat wave reached 100 degrees Fahrenheit (37.78 degrees Celsius) and broke records, on the 22nd, a heat wave warning was issued for 16 states. was lowered to



In contrast, southern China experienced record flooding this month, displacing hundreds of thousands of residents.



India has its hottest March in 122 years since weather observations began, with a high of 33.1 degrees Celsius in March.



The scientific community notes that over time, heat waves occur more frequently in different parts of the globe at the same time.



Climate scientist Andrew Dessler points out that the recent intensification of global warming has made it difficult for scientists to decide what to define as a heat wave and what to define as the 'new normal' of hot weather.



"Over time, more and more parts of the planet will experience these temperatures, and eventually, if global warming reaches sufficient levels, anywhere in the mid-latitudes of the Northern Hemisphere could exceed 100 degrees Fahrenheit (37.78 degrees Celsius)," he said. I expected it.



Some say that the cause of the heatwave is the weakening of the jet stream, a strong airflow in the upper troposphere or lower stratosphere.



As the Arctic temperature rises due to the warming effect, the temperature difference with the mid-latitudes has decreased, and the Earth's atmosphere does not mix properly, triggering an abnormal climate.



Kai Kornhuber, a climate researcher at Columbia University, predicted that extreme weather such as heat waves and heavy rains could last longer as the temperature difference between the upper and lower regions becomes smaller and the airflow slows down.
