It is not nice to be told that you have been diagnosed with a terminal condition. It is even worse to be given false hope that if you did this or that you could mitigate the problem or turn it around when it cannot. If a medical practitioner does this, they lose their job. But climate scientists do this frequently, and probably to keep their job. It is virtue-signalling to agree with national and international climate agreements which propose that we can fix this by reducing (mitigating) our carbon footprint and carbon emissions… and so continue ‘business as usual’ and live happily ever after.
My response to this is in three sections:
- Anthropogenic (human-induced) warming from greenhouse gas (GHG) emissions must be understood in the context of the natural carbon cycle, which until about 150 years ago was in equilibrium.
- The mitigation myth is that we can reduce the effects of worsening climate change by reducing anthropogenic greenhouse gas (GHG) emissions e.g., net-zero by 2050, or earlier.
- The big problem is not climate change. It is global ecological overshoot: when our ecological footprint exceeds biocapacity or sustainability. Global warming is a result. Overshoot leads to collapse and eventual extinction. The planet is now in irreversible collapse.
1. The Carbon Cycle is out of Equilibrium
Greenhouse gases (GHG) are necessary in the atmosphere to keep the planet warm at an average of 15°C surface temperature. The level of natural GHGs in the atmosphere has been in equilibrium for millennia because the earth has both emitted and absorbed natural GHGs in mostly equal measure (the natural carbon cycle). This all changed with the industrial revolution, about 1750. Since then, anthropogenic or human-caused greenhouse gases have almost doubled the atmospheric carbon dioxide concentration, and this has been the main driver of global warming. The problem has been compounded by the destruction of carbon absorbing plants and forests.
