 +====== Why wean the world from all carbon fuels? ======
 +<​html><​big><​big></​html>​
 +
 +The point I want to address here is the sense of **"​biofuels"​ being different**,​ and thus not having their carbon emissions count in emissions "​inventories"​. ​ **This is based on false assumptions,​ as I will explain, below:**
 +
 +{{:​images:​global_carbon_cycle.jpg?​nolink&​600 |}} \\ \\ \\ The premise is that you start at the beginning of the industrial age and you have a balanced ecosystem where just as much CO2 is consumed as generated.  ​
 +
 +----
 +Then you add in the extraction of carbon from under the ground, which goes into industrial-age processes, and thus produce **new CO2 contributions to the ecosystem**. This is what created the CO2 imbalance in the ecosystem. ​ Secondary "​positive-feedback"​ amplification has increased the net CO2 emissions even further. ​ Further warming would make it even worse.
 +
 +{{:​images:​globalcarboncycle2.jpg?​nolink&​600 | }}  \\ \\ \\ The argument then is made that before the industrial age, you could go take a tree or three and chop them up and use them in the fireplace. ​ The CO2 that came from them is part of the old, pre-industrial-age cycle. ​ You grew it a little, but it was capable of absorbing the difference, so **"it still can"​**. -- **NOT**
 +
 +That is a false assumption. ​ If for no other reason than the 150 years of climate change have gotten to the place where there has been significant damage to the ecosystem. ​ What used to be healthy soils under crops and meadows are now dependent on artificial fertilizers for any success at growth. ​ The soils themselves are no longer alive and that absence of soil activity **prevents major normal sequestration.** ​ The same thing is happening in our forests, which are now **significant emitters of CO2 instead of sequesterers**.  ​
 +
 +And, in the oceans, oxygen levels have decreased noticeably since the 1950s, indicating that the phytoplankton are no longer as productive as before -- therefore t**he phytoplankton is doing less sequestration than before.**
