Since ancient times, humans, as farmers and navigators, have observed and attempted to predict climate change. The scientific study of atmospheric changes began in the mid-17th century, in connection with experiments aimed at demonstrating the existence of a vacuum, which ancient philosophers denied because "nature abhors a vacuum!" If you fill a long tube with water and place it upside down in a bucket of water, the column of liquid will descend until its weight is counterbalanced by the pressure of the air on the surface of the water in the bucket: at a certain point, there will be a vacuum at the upper, closed end of the tube.
Evangelista Torricelli (1608-1647), a mathematician and physicist, a disciple of Galileo, was the first, in 1643, to build an instrument capable of detecting changes in air pressure. He described his experiment, which resulted from the discovery that variations in atmospheric pressure are linked to changes in the weather.
