Prominent Geologist Dr. Robert Giegengack dissents – Laments ‘hubris’ of those who ‘believe that we can ‘control’ climate

Global Warming/Climate Change began as a scientific discussion. It has evolved into a polarizing political argument (whenever a scientific understanding depends on a “consensus”, we know it has become political), and from there to a semi-religious campaign advanced by well-intended people who feel, deep in their hearts, that they are “saving the planet”.

Many of those people have chosen to allow their good intentions to override their scientific objectivity. As soon as people who disagree about scientific conclusions start calling each other pejorative names, we know that the discussion has become primarily political, not scientific.

I know the work of [MIT’s Dr. Richard] Lindzen, [Climatologist Dr. Roy] Spencer, [Georgia Tech Climatologist Dr. Judith] Curry, [Climatologist Dr. John] Christy, [Princeton Physicist Dr. Will] Happer, etc.I share the skepticism that these people have expressed that anthropogenic CO2 emissions represent the primary driver of the climate change now under way.

We know that the climate “warmed”, with a few unexplained reversals, from ~18,000 years ago until ~1830 AD, as a consequence of factors that have controlled climate for all of Phanerozoic time. It defies the imagination to suggest that those factors abruptly ceased to operate ~300 years ago just to accommodate our need to attribute contemporary climate change to human activity.

It beggars the imagination to assert that the natural factors that drove the warming trend from 18,000 years ago to ~300 years ago (with some unexplained temperature reversals) abruptly stopped operating at the end of the Little Ice Age to accommodate our political need to attribute climate variability to human industrial activity.

Climate models are instructive, but they lead to scenarios, not predictions. They can be manipulated to yield desired outputs.
Removing the groundwater contribution, not directly the consequence of climate change, yields a rate of global sea-level rise that is the slowest in the last 18,000 years. In prior “interglacial” times, most recently to ~125,000 years ago, global sea level rose to levels higher than the present sea level, and no humans were burning fossil fuels.

We run an insidious risk: When/if a) we learn that anthropogenic CO2 is not the primary driver of contemporary climate change; b) we drastically reduce anthropogenic output of CO2 and the climate does not respond as we have predicted; or c) we enter a period of unexplained cooling, as the mid-20th-century cooling episode, or the Little Ice Age, the credibility of climate scientists will be dashed, and with it the credibility of any scientist who tries to inform environmental policy via rigorous science.
