A Rational Response to the Ecological Crisis

Rodan's Thinker

As previously stated, the ecological crisis is the result of humankind’s uncontrolled economic expansion since the Industrial Revolution.  This led to overshoot in the 1950s as numerous environmental limits were violated.  The most serious of these violations were the skyrocketing greenhouse gas (GHG) concentrations that produced today’s climate and ocean emergencies.  My proposed response to the crisis thus begins with measures that address these disasters.  I then proceed to measures for tackling overshoot itself.

Geoengineering: the Arguments

In my last post I addressed the key facts about geoengineering.  Here I examine the arguments for and against this contentious approach.  Because emissions mitigation is often cited as an alternative to geoengineering, I begin by explaining their respective impacts on the environment.  For simplicity, I consider only the global warming effects of greenhouse gases (GHGs).  Ocean acidification and other non-warming effects are thus ignored.  See the diagram below.

The Point Of No Return

Graphic of globe poised at edge of a cliff

When a team is behind in a basketball game, time becomes a serious factor several minutes before the final buzzer. What typically happens is that the team’s normal style of play gives way to an accelerated pace and intense pressure to regain the ball and score points. The ecological crisis is roughly analogous. We’re losing a game called “human survival,” and time is now a critical factor. Any strategy for resolving the crisis must therefore incorporate a sense of extreme urgency and a fixed deadline for decisive action. I use the “point of no return” concept to address these imperatives. Continue reading

Mainstream Mitigation, or How to do NOTHING

Mainstream Mitigation - To-do-list-nothing

Unless the emissions fallacy is quickly rejected, it will be calamitous for humankind and the biosphere. The fixation on increases in greenhouse gas (GHG) concentrations while ignoring their existing levels means that global warming and ocean acidification will proceed virtually unchecked. Unfortunately the situation is even worse than this because the mainstream approach to emissions mitigation is itself severely restricted. The result is that humankind’s response to the GHG-based emergencies is essentially zero – nothing at all. My aim in this post is to substantiate this claim. Continue reading

The Emissions Fallacy

I recently said that mainstream sources such as the IPCC implicitly use a falsified model of greenhouse gas (GHG) effects when offering policy prescriptions and making public statements. The central feature of this falsification is the emissions fallacy. This is the idea that the climate and ocean emergencies should be addressed exclusively through emissions mitigation, thereby ignoring reductions in existing GHG concentrations. In this post I address the fallacy in more detail. Continue reading

Nature’s Mortal Wound

Last summer I announced here that I was writing a book to elaborate on my strategy for ecological survival. In preparing for this task I carefully examined the current state of the crisis we face. I was stunned to discover that the situation is far worse than I had thought, and that some of my long-held assumptions were no longer valid. I therefore placed the book on hold and reassessed my environmental position. Here I summarize my key findings. In future posts I will explore the details. Continue reading
