THIS POST IS A STUDY OF THE THEORY OF AGW CLIMATE CHANGE AS PROPOSED BY CLIMATE SCIENCE WITH RESPECT TO THE DISTINCTION MADE IN CLIMATE SCIENCE BETWEEN FOSSIL FUEL EMISSIONS AND CARBON CYCLE FLOWS.
- The video above is a segment of a climate science lecture by NASA scientists available on Youtube [LINK] and discussed more fully in a related post [LINK] . In this segment NASA scientist Dr. Peter Griffith explains the foundational concept of the science of anthropogenic (AGW) global warming and climate change and the kind of climate action implied by the science that humans must undertake to moderate and control the progress of global warming.
- What Dr. Peter Griffith says: “ “the carbon in this chunk of coal was taken out of the atmosphere 350 million years ago. And since the Industrial Revolution, we’ve been taking it out of the ground and using it for fuel. The burning of fossil fuel, whether it is coal, oil, or natural gas, has released this very very old carbon back into the atmosphere a lot faster than the plants and the oceans can take it out of the atmosphere. Bit by bit it is moving the Keeling Curve up“.
- To summarize this excellent lecture: What Dr Griffith has explained so well is an important feature of AGW climate change theory that is not well understood and/or often overlooked in the consideration of climate action policies. Anthropogenic global warming is NOT a theory that carbon dioxide emissions in general and from all sources increase atmospheric CO2 and therefore the temperature. It is a theory specific to the impact of the industrial economy that dug up fossil fuels loaded with carbon from carbon cycles that are millions of years old. This is EXTERNAL CARBON. It is not part of the current account of the carbon cycle.
- The essence of the theory of anthropogenic global warming (AGW) is that external carbon from very old carbon cycles in fossil fuel emissions cause warming by increasing atmospheric CO2 levels and that therefore the amount of warming can be attenuated by reducing fossil fuel emissions (Hansen, 1981) (Meinshausen, 2009) (Stocker, 2013) (Callendar, 1938) (Revelle, 1957) (Lacis, 2010) (Hansen, 2016) (IPCC, 2000) (IPCC, 2014). At the root of the proposed AGW causation chain is the ability of fossil fuel emissions to cause measurable changes in atmospheric CO2 levels in excess of natural variability because very old external carbon in fossil fuel emissions is a perturbation of the current account of the carbon cycle. AGW climate change theory is specific to the impact of the industrial economy in terms of its use of fossil fuels.
- Specifically carbon cycle flows are not a factor in the theory of anthropogenic global warming or in the design of climate action policies needed to attenuate anthropogenic global warming. So for example, respiration emissions are not a factor in the AGW equation. This important detail has been overlooked by climate activists who have not studied the theory well or forgotten these details, or are unaware of these details of the theory of anthropogenic global warming. The theory of anthropogenic global warming is specific to the industrial revolution and the industrial economy in terms of the combustion of fossil fuels.
- However, uninformed climate action enthusiasm often overlooks this detail and starts to look at all human activity, even those that predate the industrial revolution and even those that involve carbon cycle flows, to find CO2 emissions that must be eliminated to fight climate change. The identification of bovine enteric fermentation as relevant to climate change and therefore climate action and the use of this rationale for vegan diet activism is an example of the kind of misinterpretation of AGW theory described above.
