Ask most alarmists and they will insist they are winning the debate - that the world is about to embrace green orthodoxy, that carbon trading schemes are rising, that "deniers" are more marginalised than ever before.
The article in the SMH tells a very different story - rising despair, despondency, disengagement, and in some cases delusional behaviour, in the wake of serial climate disappointments.
According to environmental scientist Nicole Thornton; "It's strange. Sometimes you just don't feel you're making headway in the time you've got, before it's too late for the planet," Thornton says. "All these little things weigh you down, and then the big stuff breaks you."
The article goes on to describe more serious cases - for example, "Six years ago, a dehydrated 17-year-old boy was brought into the Royal Children's Hospital, refusing to drink water. He believed having a drink would somehow contribute to the global shortage of potable water, and became the first diagnosed case of "climate change delusion".
Personally I've always wondered if their is a correspondence between promotion of green ideas, and poor life choices made by far too many of our children - if you tell a child they have no future, that the world is about to be destroyed, that its all their parent's fault, and that there is nothing they can do about it, don't expect them to be enthusiastic about doing their homework.
However there is an even darker side to green despair. A while ago, Osama Bin Laden attempted to recruit frustrated environmentalists into his global Jihad.
Bin Laden ultimately failed in his effort to recruit frustrated greens to his campaign of mass murder, but if we don't find a way to pull back from this green brink of societal self hatred, next time we might not be so lucky.
