Change is Certain

As we concern ourselves with the ways in which humanity is responsible for the increasing march toward a climate that portends our own demise, I wonder about the significance of our input. We see that we are accelerating the increase of CO2 in the atmosphere to the point of irreversibility. The idea that we might alter this trajectory to “save ourselves” is a conceit that we have power large enough to influence this change. The earth has been through eras and epics of geologic change, growth and die outs of life forms. Change is certain. A visit to the dunes reminds me of the magnitude of geologic time and the evanescence of humanity. 
We are each a grain of sand in time.
