There is a great lack of knowledge about what climate change really is, either due to an excess of information, inaccuracy of sources or self-serving misinformation, which gives rise to a series of false myths about climate change. In this space we will address from an objective and scientific point of view what climate change is, what are its causes, its consequences and how it can be combated. In short, how climate change affects us.
Firstly, it is necessary to clarify two concepts that, although closely related, are often mistakenly taken as synonyms: climate change and global warming. There is an important difference, and that is that global warming is the cause of climate change, ie the increase in temperature of the planet caused by emissions into the atmosphere of greenhouse gases resulting from human activity, are causing variations in climate that would not occur naturally.
The Earth has already warmed and cooled naturally on other occasions, but the truth is that these cycles have always been much slower, taking millions of years, while now and as a result of human activity, we are reaching levels that in other times brought extinctions in just two hundred years.
Before going into detail about its causes and consequences, we are going to tell you why you don’t care about climate change…

CAUSES AND CONSEQUENCES OF CLIMATE CHANGE
The main cause of climate change is global warming and has multiple negative consequences on physical, biological and human systems, among other effects.
CAUSES OF CLIMATE CHANGE
Let’s start at the beginning. The greenhouse effect is a natural process that allows the Earth to maintain the necessary conditions to harbor life: the atmosphere retains part of the Sun’s heat; without the greenhouse effect, the average temperature of the planet would be 18ºC below zero.
The atmosphere is composed of various gases that, in the right proportion, fulfill their purpose. The problem is when human activities increase the emission of greenhouse gases into the atmosphere and the atmosphere retains more heat than necessary, causing the average temperature of the planet to increase and produce what we popularly call global warming.
