The Lowdown on Anthropogenic Global Warming / Climate Change

global energy flows
As a registered statistician and well-educated scientist (3 degrees and 37 years of experience), I’ve been all over the IPCC’s and others’ data they use to justify the claim that rising CO2 levels are responsible for global warming. Here’s what I found:
 
1. There is indeed evidence that the Earth has gone through a warming period over the last 70 years, one that was interrupted for at least 12 of the 18 years since the turn of the century.
 
2. There is indeed evidence that CO2 levels have also risen during the last 70 years.
 
3. CO2 is indeed a “greenhouse gas,” meaning it tends to trap a portion of IR (infrared) radiation (heat) from being radiated back into space.
 
4. CO2 is by no means the most potent greenhouse gas out there. In fact, both water and methane are far more potent.
 
5. While animal husbandry does produce some methane, termites and microbes produce far more, and deforestation is a leading cause as it interrupts the biological role of methane in the environment.
 
6. Patterns of atmospheric H2O have been significantly changed by aviation. In gaseous (invisible) form, water vapor is a potent greenhouse gas. In condensate and crystallized (cloud) form, H2O reflects sunlight back into space, but it also reflect Earth’s IR energy back to the ground. In most instances, clouds retain more heat to Earth than they protect Earth from acquiring. Both the shape and altitude of the clouds determine the net IR energy flow.
 
7. While CO2 and global warming over the last 70 years are correlated, there is no statistical evidence that either one has caused the other.
 
8. The amount of global warming occurring over the last 70 years is minuscule as compared to the temperature swings associated with the comings and goings of ice ages.
 
9. Prior to the start of the last ice age, the temperature also took a sharp, but small and short swing upward, and it, too, was accompanied by a short rise in CO2 levels.
 
10. We’re about due for another ice age.
 
11. Scientists still discount the role of sunspots, despite the fact that sunspots are strongly correlated with Earth mean temperatures. Since the Earth is certainly not affecting the cycle of the Sun’s sunspots, simple deduction says that sunspots do affect Earth’s climate.
 
12. Scientists who study the dynamics of sunspot formation have determined that sunspots are formed by the Sun’s magnetic activity, which undergoes periodic cyclical change.
 
13. Indications are strong that the Sun is close to entering a period quiessence, where very few sunspots would form, thereby resulting in an accompanying cooling period — even an ice age — here on Earth.
 
My recommandation: Hyper-insulate your house and stock up on snow shovels. Even if you wind up not needing the shovels, you’ll save on cooling. 🙂
