from Humans Are Free:
For more than 60 years, the National Aeronautics and Space Administration (NASA) has known that the changes occurring to planetary weather patterns are completely natural and normal.
But the space agency, for whatever reason, has chosen to let the man-made global warming hoax persist and spread, to the detriment of human freedom.
It was the year 1958, to be precise, when NASA first observed that changes in the solar orbit of the earth, along with alterations to the earth’s axial tilt, are both responsible for what climate scientists today have dubbed as “warming” (or “cooling,” depending on their agenda).
In the year 2000, NASA did publish information on its Earth Observatory website about the Milankovitch Climate Theory, revealing that the planet is, in fact, changing due to extraneous factors that have absolutely nothing to do with human activity.
This information has yet to go mainstream, some 19 years later, which is why [people with shady agendas] have now begun to claim that we really only have 18 months left before the planet dies from an excess of carbon dioxide (CO2).
The truth, however, is much more along the lines of what Serbian astrophysicist Milutin Milankovitch, after whom the Milankovitch Climate Theory is named, proposed about how the seasonal and latitudinal variations of solar radiation that hit the earth in different ways, and at different times, have the greatest impact on earth’s changing climate patterns.
The below two images (by Robert Simmon, NASA GSFC) help to illustrate this, with the first showing earth at a nearly zero orbit, and the second showing earth at a 0.07 orbit.
This orbital change is depicted by the eccentric, oval shape in the second image, which has been intentionally exaggerated for the purpose of showing the massive change in distance that occurs between the earth and the sun, depending on whether it is at perihelion or aphelion.
The eccentricity of the Earth’s orbit changes slowly over time from nearly zero to 0.07. As the orbit gets more eccentric (oval) the difference between the distance from the Sun to the Earth at perihelion (closest approach) and aphelion (furthest away) becomes greater and greater. Note that the Sun is not at the center of the Earth’s orbital ellipse, rather it is at one of focal points.
Note: The eccentricty of the orbit shown in the lower image is a highly exaggerated 0.5. Even the maximum eccentricity of the Earth’s orbit — 0.07 — it would be impossible to show at the resolution of a web page. Even so, at the current eccentricity of .017, the Earth is 5 million kilometers closer to Sun at perihelion than at aphelion. (Images by Robert Simmon, NASA GSFC)
“Even the maximum eccentricity of the Earth’s orbit – 0.07 – it would be impossible to show at the resolution of a web page,” notes the Hal Turner Radio Show. “Even so, at the current eccentricity of .017, the Earth is 5 million kilometers closer to Sun at perihelion than at aphelion.”
The biggest factor affecting earth’s climate is the SUN
As for earth’s obliquity, or its change in axial tilt, the below two images (Robert Simmon, NASA GSFC) show the degree to which the earth can shift on both its axis and its rotational orientation. At the higher tilts, earth’s seasons become much more extreme, while at lower tilts they become much more mild.
A similar situation exists for earth’s rotational axis, which depending on which hemisphere is pointed at the sun during perihelion, can greatly impact the seasonal extremes between the two hemispheres.
Left: The change in the tilt of the Earth’s axis (obliquity) effects the magnitude of seasonal change. At higher tilts the seasons are more extreme, and at lower tilts they are milder. The current axial tilt is 23.5°. Image by Robert Simmon, NASA GSFC)
Right: Precession — the change in orientation of the Earth’s rotational axis [this can be seen more clearly in an animation (small (290 kB QuickTime) or large (1.2 MB QuickTime))] — alters the orientation of the Earth with respect to perihelion and aphelion. If a hemisphere is pointed towards the sun at perihelion, that hemisphere will be pointing away at aphelion, and the difference in seasons will be more extreme. This seasonal effect is reversed for the opposite hemisphere. Currently, northern summer occurs near aphelion. (Image by Robert Simmon, NASA GSFC
Based on these different variables, Milankovitch was able to come up with a comprehensive mathematical model that is able to compute surface temperatures on earth going way back in time, and the conclusion is simple: Earth’s climate has always been changing, and is in a constant state of flux due to no fault of our own as human beings.
