A Review of ‘Skeptical Science’ Alleged Myths

Technical Rating: star
The website ‘Skeptical’ is popular among climate alarmists. The website alleges to refute claims by climate skeptics that global warming is not a crisis. The website features a list of 10 “Most Used Climate Myths” by climate skeptics at the top left part of the webpage. I review and rebut each rebuttal of the 10 alleged myths.

A Brief Review Of Global Temperature Variability

Technical Rating: star
This review submitted by JWR Whitfield puts the anthropogenic global warming theory and temperature variability in a historical context. Global temperatures were declining about half of the time during the period 1870 to 2013 while CO2 concentrations were increasing. There are large uncertainties in the feedback effects of water vapour and aerosols. The Svensmark hypothesis that a more active Sun leads to fewer cosmic rays, less clouds and warming is supported by experiments at the CERN facility and direct measurements. The author writes that there is a "real possibility that from about the year 2020, the global temperature may enter a declining phase ..."

A Skeptic's Submission to the Alberta Climate Change Advisory Panel

Technical Rating: star
The climate has always changed and will continue to change regardless of any action taken by Albertans or the world to reduce greenhouse gas emissions. Natural forces have caused dramatic climate change in the past. Climate model simulation of temperature do not match the observations indicating that the models are not suitable for making policy decisions. The climate is relatively insensitive to carbon dioxide emissions. Models used to calculate the social costs of carbon dioxide ignore many benefits, most notably, CO2 fertilization, and exaggerates the costs.

Modulation of Ice Ages via Precession and Dust-Albedo Feedbacks

Technical Rating: star star
The slow wobble, or precession, of the axis of the Earth causes the "Great Year" because it gives warm and cool seasons over its approximate 23,000-year cycle. The advancing ice sheets during a "Great Winter" increases the Earth's albedo, reflecting sunlight and resisting the warming effect of the next "Great Summer". As the ice sheets grow and the seas cool, CO2 also reduces as it is absorbed by the oceans. Most plants suffer severe stress at 190 ppm CO2 and die at 150 ppm, because CO2 is a primary plant-food. The concentration finally reaches the critical 190 ppm level where world flora begins to die and the Gobi steppe-lands turn into a true sand desert. The ensuing dust storms dump thousands of tonnes of dust onto the northern ice sheets each year. The interglacial periods occur only every fourth or fifth Great Year. Ice core data shows that every interglacial warming period is preceded by about 10,000 years of intense dust storms. When the next Great Summer comes along, the dusty polar ice sheets can warm and melt and the next interglacial is born. Low concentrations of CO2 near the end of an ice age causes a die-off of plants leading to dust storms, reducing the ice sheet albedo, resulting in warming and the interglacial periods.

Letter to the Prime Minister of Canada: COP21 Paris 2015

Technical Rating: star
The Friends of Science Society sent a letter to the PM of Canada, the Minister of Environment and Climate Change, and the Premiers of the Provinces. The letter begins, "As the World’s Nations scramble to make their commitments to reduce Carbon Dioxide (CO2) in the atmosphere to keep the temperature increase below 2 °C, the COP21 representatives apparently have failed to notice that there has been no warming for almost 2 decades." If further states "it is apparent that there is no match between climate models and observed reality. ... The temperature rise from 1911 to 1944 occurred before CO2 could have had a significant effect on temperature but it is very similar to the rise from 1976 to1998, and both increases are coincident with significant increases in solar activity ... Well documented climatic information for the Roman Warm Period and the Medieval Warm period show that they were both significantly warmer than our current warm period and there is nothing unique or unprecedented about modern warming."
