What are the causes of Greenhouse? Why is it a natural phenomenon? What is the role of human activity in increasing greenhouse gases and what are the consecuencias for the planet?
On the web, it can be frequently read that the effect greenhouse It would be nothing more than a theory, not proven and even that it would be a scam. Before getting into the topic, let's see what a theory is.
In science, a theory is a model or a framework for the understanding of nature and man.
In physics, the term of theory generally designates the mathematical support, derived from a small set of basic principles of equations, which allow to produce forecasts experimental for a given category of physical systems. An example is the "electromagnetic theory", usually confused with classical electromagnetism, and whose specific results are obtained from equations of Maxwell.
In this sense, we can certainly speak of the theory of effect greenhouse, just as we could talk about the temperature measurement from a satellite, since it is the application of the same leyes exactly without adding anything, but they would be bigger words for something that is nothing more than an application of a more general theory.
In common parlance, the term "theory" is often used to designate a set of speculations without true basis, contrary to the sense accepted by scientists.
Some use of the expression "Greenhouse effect theory" it plays with the ambiguity between rigorous scientific definition and ordinary language. And this is not something anodyne.
