How many years is the history of temperature records in the modern sense? How is "1the hottest since 25000" calculated?

In the modern sense, some temperature records have existed for hundreds of years, but it is predicted that this year will be the hottest weather since 125000. Some people don't understand how this calculation is worked out. In fact, some meteorologists or scholars have predicted the weather today and concluded that this year is the hottest year since 125000.

According to relevant media reports, this year is the hottest year since 125000, which has aroused the concern and worry of many residents. Some netizens believe that it is very reasonable for some experts and scholars to make such a guess. After all, this year's high temperature weather is not recorded in history, and some netizens think that this prediction is also very inaccurate. You know, the weather was not so accurate and intuitive earlier.

For today's hot weather, this is indeed very rare, so Bian Xiao thinks that some experts or scholars have made such a guess. Therefore, I also hope that in today's high temperature weather, residents everywhere can be vigilant and avoid the very serious impact of this high temperature weather on themselves. I also hope that residents in all regions can raise their awareness of prevention, especially the protection of today's ecosystem should be put on the agenda. After all, this hot weather is more or less due to too many ecosystems.

High temperature weather will cause some bad effects to a certain extent. I hope that in this environment, many residents will realize the importance of protecting the environment. If people don't protect the environment, it will be very bad for people. Therefore, I hope that people will protect the weather and the ecological environment in their daily lives, and the flowers and trees on the roadside should also be protected. You know, protecting the environment means protecting people themselves.
