Hubris in global climate science scares me. As a scientist, I often carry a British coin that bears Isaac Newton’s statement “standing on the shoulders of giants” as a reminder of humility. I try to remember that most of what I know and understand comes from the work of others before me and a larger reservoir of existing knowledge. Considering this, and hoping knowledge leads to wisdom, it becomes very important to seek wisdom in the climate-change discussion.

Consider geology. From the recent G8 discussions, it is apparent that we are intent, as humans, to mitigate global climate change. During a recent climate-change forum, I heard a distinguished International Panel on Climate Change scientist state that “113 distinguished scientists” agreed that the earth is warming. This statement was made, rather emphatically, to a room filled with hundreds of geologists who did not react at all. The fact is that geoscientists worldwide, and possibly many archaeologists, would agree.

The earth has been warming for the past 18,000 years, since the last ice age. Climate change since the last glacial maximum and the resulting Holocene (recent geologic period) warming and sea level rise is a fundamental fact in the earth sciences. Temperatures have varied, sea levels have risen and fallen and ice sheets grown and diminished many times in the past, with evidence readily apparent in nature. Data from ice core studies, sediment analyses, locations of ancient shorelines, submerged archaeological sites and even from the oral traditions of ancient peoples all verify the Holocene sea level rise plus many more in the deep past.

As a geoscientist who works in that often strange area where government policy, academia and commercial practicality overlap I fully understand the quote, paraphrased from Heraclitus, circa 500BC, that "nothing is constant except change." I suspect Heraclitus had some geoscientist in him.

A recent article in EOS, the weekly magazine of the American Geophysical Union, by Kastens and others, describes a study, by a very diverse research group including theologians, anthropologists, sociologists, as well as earth scientists, about how geoscientists think. Geoscientists think temporally, in time, far into the past and future, think of the earth as a system of complex inter-related processes, stress learning based on observations of data from what the Earth tells us, and think spatially about how things are arranged in all dimensions. Change is inherent in a geologist's understanding of the Earth and is a principal tool for defining what happens between various observed events. Thinking like a geologist is a very good approach to understanding large-scale, complex problems and this includes climate change.
