Summary for Policy Makers. The Role of IPCC. On the Climate Issue. On Humanity vs Nature. Equilibrium Climate Sensitivity: feedback or feed-forward? Why is it that, since 2001 and insisting, IPCC continues to tell that the so-called Equilibrium Climate Sensitivity (ECS) is in the. Range of 1.5 to 4.5 C? This is based on a relatively old, but still in used, lecture by one of the most famous climate modelling expert. I intend here to debunk it. ECS is a major factor used to ascribe warming to CO. Since a s...

Introduction

Summary for Policy Makers. The Role of IPCC. On the Climate Issue. On Humanity vs Nature. Climate varies all the time since the Earth exists. We don't know what constitutes a desirable climate, and it would be an impossible task to democratically agree on what the climate should be. Nor can we determine if and how a change of climatic conditions will have a positive or a negative impact for life on Earth, in particular human life. But we are always afraid of any change, because of its uncertain outcome.

Summary for Policy Makers. The Role of IPCC. On the Climate Issue. On Humanity vs Nature. Physical parameters describing the climate can be measured and monitored. They are similar to those used to characterize the current weather but their evolution must be observed over a much longer period of time, centuries and millennia. But the significance of changes is evaluated by statistical analysis of long time series. A written essay contains all of this website. You can download it as a pdf file. CHF 11&#46...

Summary for Policy Makers. The Role of IPCC. On the Climate Issue. On Humanity vs Nature. Also, a theory may remain valid only within a given application range. Newton’s laws of motion cease to be applicable at speeds near the velocity of light but are quite useful in our day to day slower life and for precise astronomical calculations. Also, highly complex systems cannot be studied by a proper combination of all relevant physical laws in such order that a solution would be found. In the 19. Century, whe...
