There is a bit of news out today re the debate over whether we are the Weather Makers, as Tim Flannery suggests (meaning human activity has so impacted the environment as to cause a catastrophic upheaval), or whether global climate change is all part of a natural cycle.
The article from Science Daily is a bit thick for non-scientists but the message is clear: physicist Pablo Verdes has created a model that includes all data on recorded and projected natural climate impacts such as volcanic activity and solar radiation–known issues with predictable patterns and outcomes–and project the impact, there is still a gaping whole in terms of explaining our current situation: rapidly rising temperatures, more frequent violent storms, melting ice caps, etc.
Following Sherlock Holmes dictum (I’m sure Dr. Verdes would not approve of a fictional character’s approval of his approach), that “when you have excluded the impossible, whatever remains, however improbable, must be the truth.” Dr. Verdes has stretched the known causes as far as possible, making the whole natural cycle theory impossible, leaving the human factor as the only remaining explanation.
The gaping hole left in his model, Dr. Verdes concludes, is filled by our own activity. Bummer.
