This special page is for the purpose of making available to interested parties the presentation slides and other presentation materials used at our monthly CASF meetings. These materials will be available to members and others who were unable to attend a particular meeting and also for future reference during discussions or when preparing blogs or other presentations.
Bernie McCune presented (5/19/2018) an excellent video briefing by Nir Shaviv on the effect of cosmic rays on the earth’s climate. The movie can be seen at this link. Since complex material in the video was supplied at an extremely fast pace, Bernie provided a number of documents for forum members to study prior to the meeting as an aide to more easily understanding the material. These documents are available here.
For our April (4/21/2018) meeting, Bob Endlich provided a briefing on the scientific grounds for reconsidering the EPA’s carbon dioxide endangerment finding. The endangerment finding was attributed to three considerations: the physical or theoretical understanding of climate, temperature records, and the output from computer models. Bob shows how these factors are just plain incorrect. In the case of physical understanding and computer modeling, the “missing tropical hot spot” shows that; he also shows how surface temperature records have been “adjusted” to essentially eliminate their cyclic nature.
Our March (3/17/2018) presentation provided by Bob Endlich was entitled the “Madden-Julian Oscillation.” This is a mostly tropical weather system originating in the Indian Ocean and moving around the Earth in from 30 to 90 days (see slide show below in which the slides change every 7 seconds.) The MJO, which can have impressive effects on weather in the USA and the Southwest states, was not even discovered until the early 1970s. It and its effects are an active research activity. Bob also presented a small sidebar on the Maritime Continent and a more extensive sidebar on Outgoing Longwave Radiation (OLR). The latter is what keeps the climate stable.
Our January (1/20/2018) and February (2/17/2018) presentations were on “The Future of Everything,” by Bernie McCune. It includes information on demographics, future growth, population pyramids, and other elements which the alarmists tell us are glimpses of imminent doom and climate catastrophe. The slides used for the two-part presentation are Part 1 and Part 2. Additional slides: Biggest US Industries, Labor Force Participation, and World GDP 2016 – 2030.
Our December meeting (12/16/17) presentation by Bob Endlich was on the California’s Santa Ana winds and associated wild fires. This presentation included weather charts and meteorological analyses showing that the presence of cold air and high pressure over Nevada pushes downslope winds which are the controlling factor in autumn wind-driven fires in California. The intense record- setting rainfall of the January and February 2017 provided ample moisture for grasses and weed growth; the lack of summer rains dominates the Mediterranean Climate of coastal California. While California’s Governor Jerry Brown, places the blame for this fire on climate change and refers to it as the “new normal,” it is the dominance of this ridge of high pressure and the lack of rainfall at the end of summer which set the stage for these wildfires. The shift from El Nino to La Nina Watch conditions occurred this year, and Bob showed the NWS’ pattern shift towards drought from California to South Carolina in La Nina winters. In a review of the October 2017, Wine Country fires, the presentation showed newspaper speculation that Governor Brown might have been partially responsible for the catastrophic October fires starting in the first place when he vetoed a bill that would have paid infrastructure funding to reduce the likelihood of sparking from power lines, poles and similar structures.
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. Recent Precipitation Measurements and More False Claims of Global Warming Effects.
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).
