Climate Change: Understanding the Causes and Consequences
of Global Temperature Shifts
Climate change refers to a variation in the global climate of the earth as
a result of a decrease or an abrupt increase in the average annual
temperatures of the earth. The cause of this phenomenon can be due to
natural processes or human actions.
Some ancient periods such as the ice ages or the Medieval Warm Period
that occurred at the end of 1300 AD were times when the earth
experienced abrupt changes in temperature, triggering other climatic
phenomena such as intense heat waves or prolonged winters. It is
known that these periods occurred as a result of extreme natural
phenomena such as orbital changes of the earth, intense volcanic
activity, plate tectonics, etc.
Scientists have been able to determine that the Earth's orbital changes
affect both the amount and the distribution of sunlight received on the
Earth's surface, which has a direct impact on its global temperature. In
the same way, the intense volcanic activity that was recorded in ancient
periods is a source of high concentrations of carbon dioxide, methane
and ash released into the atmosphere, significantly preventing the entry
of solar radiation, being responsible for the cooling periods. In addition,
plate tectonics plays a fundamental role in the relocation of continents
but can also generate earthquakes or tsunamis that cause slow changes
in the global climate.
However, the most abrupt fluctuations in global average annual
temperatures have been recorded in the last 100 years and science has
been able to confirm that it is due to human activities, with the burning
of fossil fuels, deforestation and pollution causing the changes. more
aggressive in the Earth's climate.
The burning of fossil fuels refers to the process in which coal, oil or
natural gas is used as a fuel or source of electrical or caloric energy.
