Climate change occurs even without humans

In the Dec. 2 Viewpoints piece, “Seeking a sustainable future,” we assume from the subject that the author’s conclusion is that man is the cause and the solution to “climate change” or “global warming.”

Perhaps The News would invite a paleontologist to discuss what caused the interglacial period that preceeded the last ice age that began 2.6 million years ago.

We know earth is currently in an interglacial period that began more than 13,000 years ago. Can anyone tell us what triggered the interglacial period?

Also, we are aware there were at least three ice ages and five mass extinctions of the species over many eons. Perhaps the scientist can tell us why. It certainly wasn’t human activity.

Our point here is that the climate on this planet has been and continues to be dynamic and evolving, with or without humans.
