A Crash Course in Logic and Its Relationship to the Climate Change Debate presented by Dave Toftsted, PhD, at our September 2017 meeting (9/16/17.)
The weather and circumstances surrounding the recent California forest fires and some climate history were discussed by Bob Endlich at our October meeting (10/21/17).
For our November meeting (11/18/17) Bob Endlich provided an interesting talk on precipitation, measurements, and measurement problems. His presentation was triggered by an analysis done by Dr. David Legates of U Del, presented at the America First Energy Conference in Houston on 11/9/17. The biggest problem is wind effect. In the early 1990’s National Weather Service began using precipitation gages with wind shields to slow the wind. These improvements resulted in improved catch efficiency and an accompanying upward shift in the measured precipitation amounts. Climate alarmists, unaware of the new instrumentation’s effect on measurements, claim this was strong evidence of human-caused CO2-fueled global warming.
