AFP reported that a new study warned that nearly 4 billion people globally have experienced at least 30 more days of burning heat in the past year, the main cause of which is human-caused climate change.
The report was conducted by scientists from the World Weather Attribution, Climate Central and the Red Cross - Red Heart and Red River Climate Center, and was published right before the Global Heat Action Day on June 2.
Researchers analyzed data from May 1, 2024 to May 1, 2025, comparing the actual number of extreme heat days with the hypothetical model of a world without human impact. Results: 49% of the world's population endures an average of 1 month of severe heat.
Extreme heat is defined as days with temperatures 90% higher than the temperatures previously recorded from 1991-2020 in a specific area.
Over the past 12 months, the team recorded 67 major heat waves globally, all of which had clear signs of climate change.
The Caribbean island of Aruba was hit hardest, with 187 days of extreme heat, 45 days more than the climate change-free model.
"For each burned oil barrel, each ton of CO2 released, and each small portion of increased temperature, the heat waves will affect more people," warned climate expert friederike Otto ( Imperial College London).
2024 officially became the hottest year in history, surpassing the record of 2023. January 2025 also recorded the highest temperature ever for this month.
On average, global temperatures have risen 1.3 degrees Celsius in the past five years. In 2024 alone, the increase exceeding the 1.5 degree Celsius threshold set by the Paris Agreement on climate change is a "safe limit".
The weather forecast bulletin of the Vietnam National Center for Hydro-Meteorological Forecasting said that on June 2, the Northern region (except Lai Chau, Dien Bien) and the Central region will have hot and severe heat, some places will be especially harsh with the temperature at 1:00 p.m. generally 36-38 degrees Celsius, some places above 39 degrees Celsius.
Some places recorded high temperatures such as: Lang (Hanoi) 39.4 degrees Celsius, Quang Ngai 39.3 degrees Celsius, Bac Me (Ha Giang), Son Dong (Bac Giang), Tuong Duong (Nghe An) all above 39 degrees Celsius.
The actual outdoor temperature can be 2-4 degrees Celsius, or even higher, in areas with a lot of concrete and asphalt roads.
The common humidity is 45-55%.
Forecast on 3.6: The area from Nghe An to Binh Thuan will have hot weather and severe heat with the highest temperature commonly 35-38 degrees Celsius, some places above 38 degrees Celsius. The lowest relatively humidity is commonly 50-55%.
On June 3, the North will end the hot weather.
The widespread hot weather in the Central region will end from June 4.
