Major Causes of Global Temperature Shifts
(1) Astronomical Causes
* 11 year and 206 year cycles: Cycles of solar variability ( sunspot activity )
* 21,000 year cycle: Earth's combined tilt and elliptical orbit around the Sun ( precession of the equinoxes )
* 41,000 year cycle: Cycle of the +/- 1.5° wobble in Earth's orbit ( tilt )
* 100,000 year cycle: Variations in the shape of Earth's elliptical orbit ( cycle of eccentricity )
(2) Atmospheric Causes
* Heat retention: Due to atmospheric gases, mostly gaseous water vapor (not droplets), also carbon dioxide, methane, and a few other miscellaneous gases-- the "greenhouse effect"
* Solar reflectivity: Due to white clouds, volcanic dust, polar ice caps
(3) Tectonic Causes
* Landmass distribution: Shifting continents (continental drift) causing changes in circulatory patterns of ocean currents. It seems that whenever there is a large land mass at one of the Earth's poles, either the north pole or south pole, there are ice ages.
* Undersea ridge activity: "Sea floor spreading" (associated with continental drift) causing variations in ocean displacement.

Global climate and temperature cycles are the result of a complex interplay between a variety of causes. Because these cycles and events overlap, sometimes compounding one another, sometimes canceling one another out, it is inaccurate to imply a statistically significant trend in climate or temperature patterns from just a few years or a few decades of data. Unfortunately, a lot of disinformation about where Earth's climate is heading is being propagated by "scientists" who use improper statistical methods, short-term temperature trends, or faulty computer models to make analytical and anecdotal projections about the significance of man-made influences to Earth's climate. During the last 100 years there have been two general cycles of warming and cooling recorded in the U.S. We are currently in the second warming cycle. Overall, U.S. temperatures show no significant warming trend over the last 100 years (1). This has been well - established but not well - publicized.
Controversial New Climate Change Data: Is Earth's Capacity to Absorb CO2 Much Greater Than Expected? ScienceDaily (Nov. 11, 2009) — New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.
...(Carbon Dioxide) is an essential link in a chain of vital processes which involve all the constituents of the atmosphere. Inherently it may be no more necessary to these processes, save in its thermal nature, than is oxygen, but being the minimum factor in the atmosphere it becomes regulative and decisive, because variations in it affect the whole cycle of processes dependent on it, while similar variation in the major constituents may have no appreciable effect. It is the least chemical constituent of a mixture that determines the amount of reaction. A loss of nitrogen or oxygen equal to .0003 of the atmosphere would doubtless be wholly inconsequential, while that amount of loss of carbon dioxide would be fatal to life and to many important geologic process...
The worst yardstick I can possibly imagine for any work is whether or not it gives results you want it to give.

You have got to be kidding me!
Do you really think that only calculations which 'prove' what you are wanting 'proved' are accurate, simply because they offer such 'proof'?

Thanks for your wise words.
Sadly, I already knew this would be an uphill battle because ATS is full of people who think they aren't sheep so they try to go against the norm. to prove it. However, when the norm. is actually the truth and they start to go against it, they don't care how true it is, they just don't want to be a sheep.
Sadly, now, the sheep are starting to follow the people who don't want to be sheep. This makes it harder for them to not be one.
They keep referencing the boy that cried wolf, but they are forgetting the end of the story where the boy told the truth, and nobody listened.

Can't you see that ALLisONE is smarter than you? He made this thread to debate with himself. How dare anyone step into his thread and question him! All hail ALLisONE, the smartest most gifted individual on this planet. True climate change genius and smoothed out scientist.
Edit: I forgot the obligatory huge lettering to get my point across, ALLisONE IS GENIUS
