True Progress

Among the mitigation options for climate change are the so-called geoengineering projects, one of which is the placement in space of devices to deflect, block, or diffuse a small amount of the solar radiation hitting the Earth.

This is one of the most straightforward of all the climate control technologies–if Earth is trapping too much heat or the Sun is getting too hot, just block a bit of it. No matter the cause of the increased average temperatures on Earth, this solution will reduce them. Moreover, even if future needs require additional solar radiation to maintain temperatures due to some cooling event, the same shades or reflectors might be quickly redesigned and used for that purpose as well–the beginning of a global climate control system.

Stay Focused on the Big picture

This is the fifth article in a five part series.

In this series, we have been outlining a evidence-based, constructive method to address the issue of climate change. While using this method doesn’t eliminate any disputes, it does change them from one of attacking philosophies, which are not easily changed, to disputes about data analysis. And disputes about data analysis although sometimes nearly as heated can eventually be objectively resolved. The earlier articles focued on defining the real problem, determining causes, developing solutions and evaluating policy. While those articles briefly covered all of the major aspects of the method I am advocating, there are other important ideas that must be agreed upon to some degree by those participating in the process.

Evaluating Solution Effectiveness and Translating Analysis into Policy

This is the fourth article in a five part series.

To date in this series, we’ve looked at objective measures of how to frame a problem, how to determine the causes of that problem, and consider implementing a robust solution to the problem. In the last article, we examined what to do about risk in an environment of uncertainty both from the standpoint of the problem and in the effectiveness of our solutions. In this article, I am going to discuss how we could form policy in a non-political fashion when given that kind of situation. Read the rest of this entry »

Evaluating Likelihood and Addressing Uncertainty when Applying Solutions

This is the third article in a five part series.

In the first two articles in this series we looked at identifying a problem and a functional understanding of that problem and then at determining all the causes of that problem. Now, we are going to consider how to take account of uncertain data regarding future events both in the probability that they may occur and in the degree to which they might occur. People are generally bad at statistics, which makes this part of the risk assessment process counterintuitive at times. However, risk is something we do accept on a daily basis, and so I will try and find some analogies. Again, this series is about taking politics and argumentative posturing out of the decision making process regarding climate change. To be sure we adhere to that premise, I will continue to make my examples totally neutral regarding the data and whether we are talking about a warming or cooling climate; I am discussing the decision making process.

A Root Cause Analysis on the “Failure Mode” of Changing (Increasing or Decreasing) Temperatures.

This is the second article of a five part series.

In the last article I outlined our functional model of the Earth. According to that model to explain why the current temperature of earth is the way it is, we have a primary energy input from the sun, and secondary energy inputs from other astronomical sources and internal energy from the Earth itself. The properties of the Earth that effect the temperature are the reflectivity, the percentage of energy reaching Earth reflected back out into space, and the emissivity, the ease at which the energy Earth contains can be released into space (cooling at night for example). The goal in this series is to address climate change in a real, technocratic, nonpolitical manner to elimate the arguing and posturing, and outline a process whereby people could identify what problem exists and the best most robust solution.

A Risk Assessment Approach to Climate Change Policy

This is the first article of a five part series.

It is difficult to find a more hotly debated public policy issue today than the one about potential regulatory actions related to global climate change. Much of this debate is emotional focused on various groups’ attitudes toward government action and personal responsibility, pessimism or optimism related to human interactions with the environment, and other philosophical differences. That being what it is, I think a different approach could show us the way out of that kind of divisive argument and produce positive action in an amount properly proportional to the nature of the threat. So, in a series of 5 articles, I am going to address this issue, not as a politician or a policy advocate, but as an engineer considering options and trying to reduce the risk associated with a particular problem. To maintain the non-partisan nature of this series, I am going to assume that increases or decreases in global temperatures are equally likely, and since, in theory, they have related solutions, it does not diminish the outcome of the analysis.
