Climate, food and and the connectivity paradox

At the most basic level, climate changes that cause world surface temperatures to rise are rooted in increased fossil emissions in the atmosphere. Total fossil fuel emissions are a function of key variables, most notably population, per-capita gross domestic product (GDP) and the carbon intensity of an individual unit of GDP. Understanding these forces and their relationships with each other is critical to measuring the extent of climate change and how we may seek to deal with it.

Two schools and the path to the steady state

All of economics is divided into two schools: steady state theory and infinite planet theory. They can’t both be right. You’d think the choice between them would be obvious, but infinite planet theory still holds sway in classrooms and in the halls of power where policy is made. Last month, though, brought a significant development: the manager of a major hedge fund registered a carefully reasoned dissent from infinite planet theory. And in doing so, Jeremy Grantham offered a glimpse of how and why steady state economic theory will ultimately come to prevail.

Entropy, peak oil, and Stoic philosophy

Marcus Aurelius didn’t know about entropy, but he had very clear how the universe is in continuous flow. Things change and this is the only unchangeable truth. I think this is our destiny and what we have to do. Likely, we won’t be able to save the world we know. Probably, we won’t be able to avoid immense human suffering for the years to come. Yet, we must do our best to try and – who knows – what we’ll be able to do might make a difference. I think this is the lesson that Marcus is telling to us, even from a gulf of time that spans almost two millennia.

ODAC Newsletter – May 13

Oil demand appears to finally be responding to high oil prices, most significantly in the US where petrol prices have hit $4/gallon. The IEA cut its 2011 demand forecast by 190,000 barrels/day on news of increased US stockpiles and reduced consumption, and prices dropped back from recent highs to around $110/barrel for Brent…

Fleeing Vesuvius: The psychological roots of resource over-consumption

Humans have an innate need for status and for novelty in their lives. Unfortunately, the modern world has adopted very energy- and resource-intensive ways of meeting those needs. Other ways are going to have to be found as part of the move to a more sustainable world.
