I want to preface this column by saying that I am very concerned about climate change. The rapid growth of atmospheric carbon dioxide shows no sign of abating, and I have concerns over what this will ultimately mean for the climate.
The fact is that we are conducting a global experiment with the atmosphere, and predictions of severe consequences as a result should be taken with the utmost seriousness.
Having said that, I think it is important to maintain a healthy scientific discourse on the matter. “The science is settled” is just not a statement that I am comfortable with, and I am uncomfortable labelling those who question climate change with something that evokes comparisons with Holocaust denial.
Without a doubt, some of the attacks against climate science are ignorance-based. But some of those challenges and questions are by sincere people — sometimes scientists — who doubt the science in the same way that there have always been skeptics in science. In most cases the small band of skeptics is wrong, but sometimes they overturn entrenched paradigms. Those skeptics should be engaged on the basis of science, and not politics or personal animosity. (Hint: If your willingness to accept the conclusions of a report is based on whether it agrees with your position, then your position isn’t based on science nor is it objective — regardless of which side you are on).
So, in a nutshell I accept that accumulating carbon dioxide has the potential to change the climate — and may very well be doing so now — but I believe skeptics should be engaged scientifically rather than shouted down. On the flip side, I believe skeptics must engage on the basis of the science and not engage in ad hominem attacks.
Not all skeptics are idiots. But not all proponents are well-informed, as I show in today’s column.
