Was it so hot then?

It was not so hot before. According to the existing meteorological data, from 1850 to 2022, the global annual average temperature has indeed increased by about 1.2 degrees. Many researchers blame "global warming" on "greenhouse effect" because human activities lead to excessive carbon dioxide emissions. Such a warning is necessary. After all, with the world population growth and the rapid development of production activities, the human influence on the weather is unprecedented, and no one can bear the irreversible and disastrous consequences that may result.
