A new look at current climate science and carbon dioxide, Lightfoot H. D. Full paper, unpublished as of September 2019. File: A new look at current climate science and carbon dioxide September 12 2019.PDF


This paper shows how to use available science in the form of the gas laws, AccuWeather on a smartphone, a psychrometric program, the response of CO2 and water vapor to temperature changes and back radiation to prove CO2 has little, if any, effect on atmospheric temperature. It proves the sun controls the Earth's many climates and has always done so.


To help the reader, four additional documents support the full paper:


a. Two page summary of the full paper. Gives a good overview of the full paper - File: A new look at current climate science Two page summary Sept 14 2019.PDF
b. Covering letter: Explains the origin of the concept that CO2 warms the atmosphere and this warming is amplified by water vapor. It also describes some of the harm done by the concept and indicates a new look at it is necessary. File: A new look Covering letter Sept 22 2019.PDF
c. Replace Quito with Taoudenni in the Sahara Desert: Widens the range of temperature and relative humidity File: A new look to replace Quito with Taoudenni Sept 16 2019.PDF

d. Handout for a PowerPoint presentation. It has the slides and the words that go with them. File: A new look at climate science_Handout of PowerPoint presentation Sept 12 2019.PDF
