A solid, reasonable view on global warming
Business interests in the manufacturing and energy industries, along with their political allies (like the current administration) are fond of dismissing the concerns of environmental activists by claiming that the existence of global warming and/or its basis in human behavior is still speculative, despite clear evidence of broad scientific support for such concerns. Regretfully the naysayers do have a grain of truth in that the solid evidence so far only indicates a correlation–global climate is too complex a system to definitively claim causal relationships based on only a century or so of detailed weather data (from North America, at least) plus a smattering of older data points.
Yet those who would take this lack of certainty to mean that climate-change concerns can simply be brushed aside are exhibiting our present society’s appalling lack of scientific literacy. I think that a quote from this article on climate change states the best way to look at the present situation:
The climate system is remarkably sensitive to natural variability. It’s likely that it is equally sensitive to effects brought on by human activity, changes like increased greenhouse gases, altered land-use policies and fossil-fuel dependence. Any prudent person would agree that we don’t yet understand the complexities with the climate system and, since we don’t, we should be extremely cautious in how much we ‘tweak’ the system.Scientists rarely deal in absolute Truth, but just because something isn’t 100 (or 99 or 95) percent certain doesn’t mean it’s false!
