When we are exposed to a dangerous, fickle mystery, we should follow what is known as the precautionary principle. And as John Cox explains in his book
Climate Crash, there is no more dangerous, fickle mystery than Earth’s climate system:
The climate system is nonlinear, which means its output is not always proportional to its input - that, occasionally, unexpectedly, tiny changes in initial conditions provoke huge responses. It is chockablock with feedbacks, loops of self-perpetuating physical transactions, operating on their own timescales, that amplify or impede other processes. This constant cross talk of positive and negative feedbacks is said to be balanced, more or less, at various critical thresholds in the system. Forced across such a threshold, by whatever external or internal triggering mechanism, important variables begin gyrating or flickering, and the system suddenly lurches into a significantly different semistable mode of operation, a new equilibrium. All of these variables, all of these timescales, make for a system that is full of surprises. . . . Climate is a precariously balanced nonlinear system that lurches between very different states of coldness, dryness, wetness, and warmth. Now, the precautionary principle is defined in “The Precautionary Principle in Environmental Science,” by David Kriebel et al.
Environmental Health Perspectives. Vol 109, No. 9, September 2001, as:
When an activity raises threats of harm to human health or the environment, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically. (The passage by John Cox is from page 9 of
Whole Earth Discipline: An Ecopragmatist Manifesto, by Stewart Brand. Viking Adult, 2009.)
