Kinetic energy is the cause of temperature, and heat in the atmosphere. Author; Rogelio Pérez C Summary; At present there exists a world problem known as climate change, which consists of an increase in the temperature of the planet, and as science shows that the temperature and heat of any system are given by the kinetic energies of the atoms or molecules that make up its systems, then this work explains that the cause of the increase in the temperature of the atmosphere, is due to the increase in the kinetic energy of its gas molecules, measuring the difference in the kinetic energy of the atmospheric gas molecules when they are at 14°C and 15°C, it seems simple, logical and that it has nothing special, but that the point where we are today, because the temperature of the atmosphere is explained in another way, “greenhouse effect”, is explained, because the only way to measure the temperature and heat of any system, is with the kinetic energy of the atoms or ...
