The current controversy over the cause of increasing global temperatures since the middle of the 20th century comes from the IPCC First Assessment Report issued in 1990. Current, reliable evidence shows the Earth has just come through a warm period. It...
This article is best viewed on a large computer screen. Here are notes to help you understand the analysis by the authors concerning the very minor role of atmospheric carbon dioxide in warming the planet. See more articles by Douglas Lightfoot and...
The temperature recorded by AccuWeather includes all the local physical effects from latitude, elevation, Sun angle, Sun's variability, proximity to oceans and lakes, clouds, any recent volcanic action, as well as the interaction of the 99% non-GHG...
Plants make our food and oxygen. Plants take CO2 and water into their cells. Then, sunlight and chloroophyll, the green coloring matter, convert them into simple sugars and release oxygen to the atmosphere. The plant transforms the simple sugars into...
The psychrometric mathematical model of the Earth's atmosphere accurately separates the warming effects of carbon dioxide (CO2) and water vapor. The methodology uses empirical data to show that the warming effects of CO2 and water vapor are...
The data show water vapor is one thousand to seven thousand times more effective at warming the atmosphere than CO2. The warming effect of CO2 is linear with concentration. CO2 is above its boiling point, and the relationship is linear. Water vapor is...
We constructed the following material to help you in your efforts to bring a rational discussion to the study of climate. There is a need for more people to critically analyze climate policy and news, much of which is misinformation. We hope this...
Science is governed by the Laws of Physics and the Scientific Method. In the case of Climate Science, the more specific requirements are in the Laws of Thermodynamics. Our latest paper is not based on any simulation or advanced computer modelling, but...
This article is best viewed on a large computer screen. This is a handout of text for slides about the effect of carbon dioxide (CO2) in warming the Earth’s atmosphere. It shows that water vapor ranges from 0.1 to 44.0 times that of CO2. The increased...
This article is best viewed on a large computer screen. This study provides temperature estimates about the effect of carbon dioxide (CO2) in warming the Earth’s atmosphere. It compares the grams of water vapor per kilogram (kg) of dry air with the...
