I’m sure the majority (but not all) of my IPCC colleagues cringe when I say this, but I see neither the developing catastrophe nor the smoking gun proving that human activity is to blame for most of the warming we see. Rather, I see a reliance on climate models (useful but never “proof”) and the coincidence that changes in carbon dioxide and global temperatures have loose similarity over time.
There are some of us who remain so humbled by the task of measuring and understanding the extraordinarily complex climate system that we are skeptical of our ability to know what it is doing and why. As we build climate data sets from scratch and look into the guts of the climate system, however, we don’t find the alarmist theory matching observations. (The National Oceanic and Atmospheric Administration satellite data we analyze at the University of Alabama in Huntsville does show modest warming — around 2.5 degrees Fahrenheit per century, if current warming trends of 0.25 degrees per decade continue.)
It is my turn to cringe when I hear overstated-confidence from those who describe the projected evolution of global weather patterns over the next 100 years, especially when I consider how difficult it is to accurately predict that system’s behavior over the next five days.
Mother Nature simply operates at a level of complexity that is, at this point, beyond the mastery of mere mortals (such as scientists) and the tools available to us. As my high-school physics teacher admonished us in those we-shall-conquer-the-world-with-a-slide-rule days, “Begin all of your scientific pronouncements with ‘At our present level of ignorance, we think we know …'”
I haven’t seen that type of climate humility lately. Rather I see jump-to-conclusions advocates and, unfortunately, some scientists who see in every weather anomaly the specter of a global-warming apocalypse. Explaining each successive phenomenon as a result of human action gives them comfort and an easy answer.
[Editor’s note: Quite likely the one Southern Baptist who best combines Biblical and theological training with scientific expertise in climatology and global warming studies, Dr. John Christy, an ordained minister former Baptist missionary as well as senior research scientist at the University of Alabama, Huntsville, is an expert reviewer for the UN International Panel on Climate Change and a leading critic of global warming alarmism. As an expert reviewer for the IPCC, he ironically shares the Nobel Peace Prize awarded chief alarmist Al Gore. This article, which we ran in the newsletter shortly after it first appeared in the Wall Street Journal, bears repeating now in light of developments in the Southern Baptist Convention.–ECB]
