Another skeptic

CO2 and climate: a viewpoint of engineering.

Rarely has a debate as concerned about public opinion and the media as that rages today about climate change and the possible responsibility of humanity to it.

Climate scientists themselves are divided into two warring factions. The majority of them seem to fall into the camp “official” one who supports a view that can be summarized in four points:

– The temperature of the earth is increasing and will continue to do so dangerously
– Human activities and particularly emissions of carbon dioxide (CO2) are the major cause of the phenomenon
– We must act to control and reduce these
– There are ways to get there and need to implement urgently to “save the planet.”

But other climatologists, who are increasingly vocal, challenging the very foundations of that reasoning. They argue that climate variations have always existed, and there is no evidence that human activities, including CO2 emissions, have a significant influence on its evolution and the average global temperature.

When oneself is not a climatologist – and there are very few in the world – is it possible to get an opinion? Faced with the difficulty of the subject and scope of the controversy, the temptation is to respond negatively to this question. This article will try to show that it is not, and that a rational approach that could be described as an engineer, that is to say from the facts, can lead a number of conclusions questionable and difficult to throw new light on this complex subject.

Rather than enter the debate between them climatologists about climate change and the potential for humanity to it, the reasoning suggested taking the problem upside down and share a simple question “What is our flexibility with regard to CO2 emissions? Y do we something?
