Temperature and CO2 History

by Dr. Ed Berry Temperatures Let us look at temperatures. Here is a plot of the reconstructed temperatures and CO2 concentrations for the past 600 million years. We observe that CO2 is near its lowest concentration for the past 600 million years. Historically, CO2 concentration has been much higher than it is now. We know…

Why our glaciers are melting

by Dr. Ed Berry This chart shows how glaciers have been melting at a constant rate since about 1820. They began melting long before human carbon dioxide emissions became significant starting in about 1950. This raises these questions: How can we blame our carbon dioxide emissions for glacier melting when the glacier melting began about…

The Common Alarmist Logical Fallacy

by Dr. Ed Berry Here is an easy way to illustrate the common logical fallacy called “affirming the consequent. Consider the following logic statement: If Human CO2 causes global warming Then Human CO2 may cause glaciers to melt. (A implies B.) Glaciers are melting. Therefore, Human CO2 causes global warming. (B implies A.) It is…

Human CO2 emissions are irrelevant

by Dr. Ed Berry Tom Quirk shows natural variability of the climate is the prime cause of increasing CO2, not the emissions of CO2 from the use of fossil fuels. See: Energy & Environment, 20, 1-2, Jan 2009, pp 105-121 The IPCC core hypothesis is that human CO2 causes all the increase in atmospheric CO2…
