The Deep Politics of Rational Action

In my previous post I used the ideas of deep politics to determine that the capitalist ruling class is primarily responsible for the lack of rational action on the ecological crisis.  Such action would include immediate solar radiation management, rapid reductions in greenhouse gas concentrations, and the transition from economic expansion to contraction.  In this post I again use these ideas, but this time to locate an alternative social group that might take the necessary steps.

The Deep Politics of Ecological Inaction

In a recent post I proposed the following three-part response to the ecological crisis:

  1. Immediate solar radiation management in the Arctic to prevent methane releases that would sharply accelerate global warming;
  2. Rapid drawdown and aggressive mitigation of greenhouse gases to reach safe atmospheric concentrations; and,
  3. Decreased per-capita consumption, lower populations, and higher efficiencies to significantly reduce the global economy’s environmental impact.

Although these steps are necessary to solve the crisis, there is no indication they will be implemented in the time that is ecologically available. Continue reading

A critique of two marches

For the environmentally concerned, two important marches were held this month.  On April 22 (Earth Day) the March for Science defended the integrity of science while protesting the anti-science policies of the Trump administration.  On April 29 the People’s Climate March chanted for environmental justice and jeered Trump’s anti-climate policies.  Although these events were superficially encouraging, they both featured major errors that must be identified and critiqued.

Geoengineering taboo is waning, but urgency still missing

A few days ago the Guardian newspaper printed an article by Martin Lukacs that criticized an upcoming experiment on solar geoengineering (i.e., solar radiation management or SRM).  In today’s Guardian the main target of that criticism, David Keith, offered an effective rebuttal.  The only problem with Keith’s position is that it continues to downplay the extreme urgency of our climate predicament.

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. Continue reading

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
