https://clear.ucdavis.edu/explainers/biogenic-carbon-cycle-and-cattleA discussion of the biogenic carbon cycle, specifically The Methane Cycle. The earth has natural carbon gas clearing capabilities which according to theory have been exceeded by the use of fossil fuels on the scales humans use them. Biogenic carbon has been part of this cycle for nearly as long as the earth has existed.
It's important that people understand the underlying science of carbon gases to be able to assess specific threats of climate change/global warming and the measures being taken to manage it. If they will be effective if and a particular threat like cow farts is actually a threat or not.
The environmental movement has created a bunch of false hypotheses that you see pushed by people like AOC claiming global warming will be irreversible in 12 years or other icons of the environmental like Greta Thunberg with no scientific background to speak of.
The earth theoretically has supported life at temperatures above what we're seeing now, so when scientists claim that we have the hottest year on record you have to determine how long we have been able to record global temperatures. This is an important reference point.
You also must ask why is the natural CO2 clearance method of photosynthesis done by plants unable to keep up with the production of CO2 added due to combustion. Is this CO2 molecularly different than CO2 produced by animal respiration and other natural processes? Have we reached a point where we have destroyed sufficient plant life in comparison to the animal population to balance CO2 production versus clearance and conversion to O2?
This is where I find the discussion with people who are dismissive of environmental issues problematic. This balance point does exist and we're not sure what it is. In a plant abundant environment, CO2 clearance and conversion to O2 was never an issue. We humans need plentiful O2 to function mentally and physically.
There has been a discussion by many who are concerned with the rise of carbon gases, specifically, CO2, that if the atmosphere reaches a certain PPM (Parts per million) of CO2, we will have severe mental impairment as brain function is severely impaired in low O2 environments. Even common people have seen O2 depletion lead to brain damage or death such as when a car exhaust can build up CO in a closed environment leading to asphyxiation.
We have also seen areas of the ocean suffering from O2 depletion lead to dead sea life as the natural processes from the plant life in the ocean that oxygenate the ocean are depleted causing asphyxiation for living organisms requiring oxygen in the ocean. This is rare, but does happen.
So it is important that we study the balance between plant and animal life that maintains the cCO2 clearance cycle and oxygen conversion even more than we watch the warming environment. The warming environment can rise only so far as it is unlikely that greenhouse gases lead to widespread desertification of the earth. Rather it will kill off a large supply of animal life including us naturally balancing the carbon gas environment, increase plant life to clear the carbon gases leading to a high oxygen environment restoring the balance point and creating an environment where animal life can flourish again. This idea of extinction is unlikely and a rebalance is more likely.
Humans throughout their history are always trying to figure out how this planet works. They have so far been able to beat every attempt to make them extinct. We are not dinosaurs. We are far, far, far more intelligent and capable of manipulating our environment to be hospitable to human life than any animal that has ever existed on this planet. This time is likely no different as we need to understand better how to enhance carbon clearance without being excessively stupid about it using some kind of climate Armageddon to push change and also ensure that competing agendas like the anti-animal cruelty movement or the green energy lobby doesn't push false threats in the interest of making money or pushing a social agenda that aligns with their personal ethics.
I think there is sufficient evidence to show cow farts and other natural forms of methane release are naturally recycled from the environment and thus only important to global warming if the normal process of methane removal is overwhelmed. Nowhere does this require the complete end of animal farming. That is a far left, anti-animal cruelty agenda no in line with the science that shows the process of methane removal from the environment.
I tried to make this as succinct as possible to provide some reading material for those interested in climate change as more than a media driven boogieman. I think it is important for people to engage with the science that is being used to govern the world. It is an increasingly bad idea in an age where information is easy to dispense and consume to avoid self-education on a variety of topics important to the decision masking process of governments and industry. Environmental issues are a complex topic involving complex biological processes that you have to study to understand. Everyone should take more time to do so.
