Global warming is defined as the phenomenon that in recent decades has been affecting planet earth and refers to the progressive increase in the temperature of the oceans and the atmosphere without mentioning that said increase is projected even more in the near future, that is With this phenomenon as shown by the different climate changes that have been occurring in recent times, some of the effects that global warming is having on the planet is the increase in ocean levels, caused by a melting of large glaciers, as well as the destruction of large areas of jungle, produced by the increase in temperature, which affects mostly animals and faunaof said places. Without a doubt, the main responsible for this phenomenon is man, since the indiscriminate use of the earth's resources as well as the emission of different types of toxic elements into the environment, have accelerated this process.

Said increase in both the temperature of the atmosphere and the sea have serious consequences in the different activities in which man has participation, whether in the places where he lives, the food he can sow as well as the place where the crops are sown. themselves. It is for this reason that it is necessary to know at what speed and how much the warming is, in addition to the causes of it, since such knowledge is possible to apply new ways to manage resources and thus be able to preserve the life of the planet for much more time.

An issue that is closely related to global warming is the so-called greenhouse effect, which originates at the moment in which some gases found in the atmosphere begin to retain heat, which makes these gases allow the passage of light, but they still maintain the aforementioned heat. This occurs in the following way, first the light that comes from the sun reaches the earth, where it is used and the rest is returned to the atmosphere but this time as heat, part of that heat is absorbed by greenhouse gases, while the rest is returned to the atmosphere, but as these gases increase, the greater the heat that is retained and consequently the greater the damage to the planet.
