The climate change story is half true

Posted on by

The climate change story is true in some respects: The climate is indeed changing. And CO2 emissions do seem to affect climate. Burning fossil fuels does indeed make a difference in CO2 levels.

The problem I have with the climate change story is that it paints a totally inaccurate story of the predicament the world is facing. The world’s predicament arises primarily from too little affordable resources, especially energy resources; climate change models tend to give the illusion that our problem is one of a superabundance of fossil fuels.

Furthermore, the world economy has no real option of using significantly less energy, because the economy tends to collapse when there is not enough energy. Economists have not studied the physics of how a networked economy really works; they rely on an overly simple supply and demand model that seems to suggest that prices can rise endlessly.

The quantity of energy supply affects both the supply and demand of finished goods and services. History shows that the result of inadequate energy supplies is often collapse or a resource war, in an attempt to obtain more of the necessary resources.

Climate scientists aren’t expected to be economists, but have inadvertently picked up the wrong views of economists and allowed them to affect the climate models they produce. This results in an over-focus on climate issues and an under-focus on the real issues at hand.

Let’s look at a few issues related to the climate change story. Continue reading →

Why We Should Be Concerned About Low Oil Prices

Posted on by

Most people assume that oil prices, and for that matter other energy prices, will rise as we reach limits. This isn’t really the way the system works; oil prices can be expected to fall too low, as we reach limits. Thus, we should not be surprised if the OPEC/Russia agreement to limit oil extraction falls apart, and oil prices fall further. This is the way the “end” is reached, not through high prices.

I recently tried to explain how the energy-economy system works, including the strange way prices fall, rather than rise, as we reach limits, at a recent workshop in Brussels called “New Narratives of Energy and Sustainability.” The talk was part of an “Inspirational Workshop Series” sponsored by the Joint Research Centre of the European Commission.

My talk was titled, “Elephants in the Room Regarding Energy and the Economy.” (PDF) In this post, I show my slides and give a bit of commentary.

The question, of course, is how this growth comes to an end.
