This is the problem, in a nutshell. When we delve too deeply into the facts, it is traumatizing, even for those of us who are well aware of our predicament. So denial, or simply "the default setting" as you call it, is an understandable psychic defense against feelings of hopelessness and despair. My own view is that the best antidote is summed up in a slogan I invented (and put on a bumper sticker): "Grow Gardens, Grow Community, Grow Awareness." In that order! First, we go out in our yards and plant some seeds--especially things that we can eat when they mature (spring greens, for example, are very easy to grow in the early spring). This may set us on a journey toward greater food independence. Next, we can share our gardening knowledge and enthusiasm with our neighbors, and ask their advice if they know more than we do. This grows community, and sets us in the direction of greater collaboration--which may come in handy as we are buffeted by one climate catastrophe after another. Finally, as all this happens, grow awareness of our global predicament and its dire implications, but in the context of community, this is more likely to lead to contingency planning together, rather than solitary grief and despair...
