The simple  graph shows two feedback loops that interact to make climate change and its consequences worse, leading to an unexpected (& inescapable?) dilemma. Presently,  there are 413 ppm of CO2 gasses in the atmosphere. Even without any further emission of greenhouse gasses, this high level of CO2 in the atmosphere will ensure constantly worsening climatic consequences because of delays that operate in the climate system. The dilemma is caused by relentlessly worsening of extreme weather events, droughts, forest fires etc., the need for draconian measures to deal with the situation and the opposition to the measures, described by the feedback loop B2.This opposition is rooted in human nature, the psychological defence mechanisms that cause us to repress or even deny unpalatable truths that threaten our basic assumptions and the way we understand life. Together,  the loops B1 & B2 create a vicious reinforcing loop that describes the escalating and worsening situation created by the dilemma.
