The world will enter an era of great frosts
The intense cold of a week ago is not atypical, but is part of the beginning of a recurring pattern, according to Víctor Velasco Herrera, a researcher at the Institute of Geophysics of the National Autonomous University of Mexico (UNAM).
“At the beginning of the century the solar deficit began, a phenomenon in which the Sun for a large part of this century will begin to decrease its activity. Each year less solar energy will reach us, which will have repercussions throughout the world and, of course, snowfalls are expected in Mexico City as it already happened in 1967”, says this UNAM researcher.
The thesis in question is that total solar radiation is the main source of energy for the Earth’s climate system and, consequently, its variations can contribute to natural climate change.
“This variability is characterized, among other manifestations, by decadal and secular oscillations, which has given rise to several attempts to estimate future solar energy,” reads the Reconstruction and prediction of total solar irradiation: from the medieval warm period to the 21st century, Article published by Velasco in New Astronomy, an international scientific journal.
From which it follows that every time the king sun sends less energy to Earth, historic snowfalls are reported; For example, Velasco says that in the time of the great Tenochtitlan, Lake Texcoco froze several times.
“This alerts us to the problems that we are going to face in the coming decades: not only health, but also food production and energy consumption, so I would recommend the authorities to have a short- and medium-term plan in this regard” , says Victor Velasco.
