Our relative understanding of temperature
The average human body temperature is 37° Celsius. From around 38°, one speaks of fever, a temperature of more than 42° is usually fatal.
Between life and death lie 5° Celsius, in a system which, if we consider the human body as a whole, can certainly be regarded as complex. What effects, then, will even small variations in temperature have in a system many times more complex than our earth?
Our understanding of temperature differences all too often proves to be distorted. We infer from our individual, external temperature sensation to the behavior of several interdependent and interrelated systems during temperature changes. For our perception, a 2° difference means changing from a sweater to a T-shirt. For the human body system, on the other hand, it already means severe stress and that we have a high fever.
Does our earth have a fever?
