2.3   Climate control may not be entirely LTI

Earth’s climate control system may not be entirely LTI

It seems likely that once CO2 levels reach a level that is too high, generally described by Climate Scientists in the IPCC Reports as a “Tipping Point”, the system destabilises and this unlocks and releases very large amounts of CO2 and Methane from trees and ice, that all goes into the Earth’s Atmosphere. 

Systems engineers call this type of behaviour a “positive feedback loop” and they know this type of system behaviour is highly non-linear, extremely difficult to control, and often very dangerous. These ‘over-unity’ feedback systems will Output more than is Input, so the Output just keeps increasing faster and faster. If the feedback loop becomes very large, then even if the original Input reduces to Zero, the Output can keep on growing.

It is likely that this non-linear positive feedback process is already starting to happen because of recent massive Australian Bushfires and the melting of permafrost in Sibera, among many other events, which all have ‘unlocked and released’ enormous amounts of CO2 and Methane in the past 2 years. 

The following diagram generally and simply shows how a climate change positive feedback system works.
