For anyone reading this thread the article being responded to is an excellent example of the challenges we are facing. Climate change is not a normal problem that is understandable or solvable by traditional problem solving techniques. This overwhelms most people who have never dealt the nonlinear complex problems. The link is to a fairly good wikipedia introduction to nonlinearity. In short, climate change is a problem created by humans through population growth and two hundred plus years of carbon pollution that only began to become apparent early in the 20th century. The patterns are clear and the results are understood but not at the level of a high school textbook. We are dealing with chaotic conditions that we can control only with large scale, long term effort. As this article and its responses from the confused illustrate, we may not be able to survive this. Human psychology is consistent. A normal reaction among a percentage of the population to a problem they cannot understand is to deny it exists and become angry at their own ignorance projecting it on “others”.
