Who cares about cause? Something must be done!

An excellent opinion piece by Vin Suprynowicz is here.

Excerpts:

How could meeting all our current power needs with windmills or solar cells (ignoring the costs) possibly cause Lake Mead to fill with water? How could socking us with $5 billion in "carbon taxes" -- doubling the cost of turning on a light switch or pumping a gallon of gasoline, for starters -- cause Lake Mead to fill with water? What evidence is there that this would do any more good than rounding up 10,000 widows and burning them as witches?
...
But how can you deny we've been cursed by the witches? Aren't the lakes drying up? Aren't there storms and wildfires everywhere? Don't children have cancer and asthma? Why can't we all just agree these things are happening, and start to round up and burn the witches? There's no time left to beat around the bush and wait for all this tedious testing of "causality"! Who cares what's causing it? Something must be done!
