A bright, warm, sunny, late October day.
The sky is blue, butterflies are dancing through the air and a fat red dragonfly buzzes us as we walk along the footpath in our T-shirts.
I want to lose myself in how lovely it is, but part of me is saying "We'll be nostalgic about cold cloudy autumn days with proper rain once climate change kicks in".
Curses! Sustainable development change agents have a hard time of it, what with being so aware of impending ecosystem collapse and the paltry efforts our organisations are making to stop it.
Can't we just enjoy the sunshine and let tomorrow worry about itself?
How do we feel about it? And how do we help ourselves feel effective, empowered and persuasive in the face of the latest information on ice melt, ocean pH and HIV/Aids? This survey of organisational change agents may help you feel less alone.
Take a look at this slide show, that illustrates the results of the same survey and draws some conclusions.
What do you feel about it?
