Maybe

It’s not my own point of view, but some sagacious thinkers are predicting an extremity of crisis by the end of this century.

The sea levels have risen over the last fifty years, but very little. Does that become a parabolic function over the next couple of decades? There are droughts affecting swathes of territory and affecting major rivers. But there have always been droughts. Are the droughts now different in kind … are they harbingers of ecological crisis?

The answers to these questions are not definite at this moment in time. Will they be within decades?

I feel certain about looming crisis. But I don’t think the lives of our grandchildren will be all so majorly affected. Yet some authors that I respect do think so:

“This civilization is finished: so what is to be done?” (Rupert Read):

Apologies to the Grandchildren: Reflections on Our Ecological Predicament, Its Deeper Causes, and Its Political Consequences (William Ophuls):

Maybe they’re right.
